Background HealthCyberMap aims at mapping parts of health information cyberspace in novel ways to deliver a semantically superior user experience. This is achieved through "intelligent" categorisation and interactive hypermedia visualisation of health resources using metadata, clinical codes and GIS. HealthCyberMap is an ArcView 3.1 project. WebView, the Internet extension to ArcView, publishes HealthCyberMap ArcView Views as Web client-side imagemaps. The basic WebView set-up does not support any GIS database connection, and published Web maps become disconnected from the original project. A dedicated Internet map server would be the best way to serve HealthCyberMap database-driven interactive Web maps, but is an expensive and complex solution to acquire, run and maintain. This paper describes HealthCyberMap simple, low-cost method for "patching" WebView to serve hypermaps with dynamic database drill-down functionality on the Web.

   Results
   The proposed solution is currently used for publishing HealthCyberMap GIS-generated navigational information maps on the Web while maintaining their links with the underlying resource metadata base.


   Conclusion
   The authors believe their map serving approach as adopted in HealthCyberMap has been very successful, especially in cases when only map attribute data change without a corresponding effect on map appearance. It should be also possible to use the same solution to publish other interactive GIS-driven maps on the Web, e.g., maps of real world health problems.

PHS On The Web (POTW) is a web-based, interactive mapping tool for citizens, landowners, local governments, developers, conservation groups and others to find basic information about known locations of Priority Habitats and Species (PHS) in Washington State. PHS is a source of best available science that can inform local planning activities, development projects, conservation strategies, incentive programs, and numerous other applications. The three GIS layers provided in this file geodatabase are the layers displayed in the POTW (Public) online map application. The three layers are scheduled to be updated on the first Monday of each month. These three GIS layers are: WDFWPHSPlusPublicLine, WDFWPHSPlusPublicPoint, and WDFWPHSPlusPublicPolygon. In these three layers, sensitive species are not shown as mapped (as a point, line, or polygon) but the locations are masked as a Section (one square mile), Quarter Township (nine square miles), or Township (thirty-six square miles) polygons.Sensitive species and habitat information are defined in WDFW Policy 5210. Priority habitats and species locations deemed sensitive by WDFW are not publicly displayed beyond a certain resolution (e.g., township or section) due to an increased risk of human interference. Sensitive data is exempt from public disclosure under the Public Records Act; this term is defined in RCW 42.56.430. Sensitive species are any wildlife species likely to become endangered or threatened; this term is defined in WAC 200-200-100. Qualifying landowners, university researchers, government agencies, and tribes may request PHS maps that contain this sensitive data.Since this GIS layer contains non-sensitive species information, it can be used without limitations, but please acknowledge the Washington Department of Fish and Wildlife (WDFW) as the source of this information. Please do not distribute this data, instead refer others to WDFW. If you have any questions about this layer, you can contact PHS at this email address: phsproducts@dfw.wa.gov with a subject line of the email being "POTW Public Dataset Question".Please note, although mapped PHS data is useful for determining the general extent of priority species or habitats, the department has not surveyed the entire state of Washington. PHS map data is meant to serve as a starting point to identify priority habitats and species. It is not meant to replace or preempt more detailed field-based, site-level mapping. Site-specific surveys are usually needed to rule out the presence of priority habitats or species. PHS maps do not provide an official agency determination of the potential impacts to fish and wildlife of a specific project.Additional ResourcesPHS On The Web Application: https://geodataservices.wdfw.wa.gov/hp/phs/PHS On the Web Map Service: https://geodataservices.wdfw.wa.gov/arcgis/rest/services/PHSOnTheWeb/PHSOnTheWebPublic/MapServer

USACE personnel compiled multiple shapefiles and databases with historic high water marks (HWM) records from within the Omaha District. This data was combined with the digitized HWM USACE Books 1-14. Not all databases had a geolocation for sites, these are not included in this file geodatabase.USACE Omaha District digitized paper high water marks to ArcGIS format. Dataset consists of high-water marks from USACE Books 1 - 14. Book dates range from 1960 to 1993 and points were entered based off referencing paper maps. Due to the age of the HWM paper records and potential changes in geography – the exact physical location of the HWM may differ from the location documented in the shapefile. Staff made their best effort to locate HWM based on description provided in the paper records. The user should be aware of the low level-of-accuracy that may be associated with some HWM. This data is provided to understand the rough magnitude of past historic flood events and should not be used as the only source of information for calibration purposes. Original USACE is located in book form at the Omaha District Office as well as scanned at "

This site provides access to download an ArcGIS geodatabase or shapefiles for the 2017 Texas Address Database, compiled by the Center for Water and the Environment (CWE) at the University of Texas at Austin, with guidance and funding from the Texas Division of Emergency Management (TDEM). These addresses are used by TDEM to help anticipate potential impacts of serious weather and flooding events statewide. This is part of the Texas Water Model (TWM), a project to adapt the NOAA National Water Model [1] for use in Texas public safety. This database was compiled over the period from June 2016 to December 2017. A number of gaps remain (towns and cities missing address points), see Address Database Gaps spreadsheet below [4]. Additional datasets include administrative boundaries for Texas counties (including Federal and State disaster-declarations), Councils of Government, and Texas Dept of Public Safety Regions. An Esri ArcGIS Story Map [5] web app provides an interactive map-based portal to explore and access these data layers for download.

The address points in this database include their "height above nearest drainage" (HAND) as attributes in meters and feet. HAND is an elevation model developed through processing by the TauDEM method [2], built on USGS National Elevation Data (NED) with 10m horizontal resolution. The HAND elevation data and 10m NED for the continental United States are available for download from the Texas Advanced Computational Center (TACC) [3].

The complete statewide dataset contains about 9.28 million address points representing a population of about 28 million. The total file size is about 5GB in shapefile format. For better download performance, the shapefile version of this data is divided into 5 regions, based on groupings of major watersheds identified by their hydrologic unit codes (HUC). These are zipped by region, with no zipfile greater than 120mb: - North Tx: HUC1108-1114 (0.52 million address points) - DFW-East Tx: HUC1201-1203 (3.06 million address points) - Houston-SE Tx: HUC1204 (1.84 million address points) - Central Tx: HUC1205-1210 (2.96 million address points) - Rio Grande-SW Tx: HUC2111-1309 (2.96 million address points)

Additional state and county boundaries are included (Louisiana, Mississippi, Arkansas), as well as disaster-declaration status.

Compilation notes: The Texas Commission for State Emergency Communications (CSEC) provided the first 3 million address points received, in a single batch representing 213 of Texas' 254 counties. The remaining 41 counties were primarily urban areas comprising about 6.28 million addresses (totaling about 9.28 million addresses statewide). We reached the GIS data providers for these areas (see Contributors list below) through these emergency communications networks: Texas 9-1-1 Alliance, the Texas Emergency GIS Response Team (EGRT), and the Texas GIS 9-1-1 User Group. The address data was typically organized in groupings of counties called Councils of Governments (COG) or Regional Planning Commissions (RPC) or Development Councils (DC). Every county in Texas belongs to a COG, RPC or DC. We reconciled all counties' addresses to a common, very simple schema, and merged into a single geodatabase.

November 2023 updates: In 2019, TNRIS took over maintenance of the Texas Address Database, which is now a StratMap program updated annually [6]. In 2023, TNRIS also changed its name to the Texas Geographic Information Office (TxGIO). The datasets available for download below are not being updated, but are current as of the time of Hurricane Harvey.

Soil is the foundation of life on earth. More living things by weight live in the soil than upon it. It determines what crops we can grow, what structures we can build, what forests can take root.This layer contains the physical soil variable percent clay (clay).Within the subset of soil that is smaller than 2mm in size, also known as the fine earth portion, clay is defined as particles that are smaller than 0.002mm, making them only visible in an electron microscope. Clay soils contain low amounts of air, and water drains through them very slowly.This layer is a general, medium scale global predictive soil layer suitable for global mapping and decision support. In many places samples of soils do not exist so this map represents a prediction of what is most likely in that location. The predictions are made in six depth ranges by soilgrids.org, funded by ISRIC based in Wageningen, Netherlands.Each 250m pixel contains a value predicted for that area by soilgrids.org from best available data worldwide. Data for percent clay are provided at six depth ranges from the surface to 2 meters below the surface. Each variable and depth range may be accessed in the layer's multidimensional properties.Dataset SummaryPhenomenon Mapped: Proportion of clay particles (< 0.002 mm) in the fine earth fraction in g/100g (%)Cell Size: 250 metersPixel Type: 32 bit float, converted from online data that is 16 Bit Unsigned IntegerCoordinate System: Web Mercator Auxiliary Sphere, projected via nearest neighbor from goode's homolosine land (250m)Extent: World land area except AntarcticaVisible Scale: All scales are visibleNumber of Columns and Rows: 160300, 100498Source: Soilgrids.orgPublication Date: May 2020Data from the soilgrids.org mean predictions for clay were used to create this layer.

This layer can be combined with your data and other layers from the ArcGIS Living Atlas of the World in ArcGIS Online and ArcGIS Pro to create powerful web maps that can be used alone or in a story map or other application.Because this layer is part of the ArcGIS Living Atlas of the World it is easy to add to your map: In ArcGIS Online, you can add this layer to a map by selecting Add then Browse Living Atlas Layers. A window will open. Type "world soils soilgrids" in the search box and browse to the layer. Select the layer then click Add to Map. In ArcGIS Pro, open a map and select Add Data from the Map Tab. Select Data at the top of the drop down menu. The Add Data dialog box will open on the left side of the box, expand Portal if necessary, then select Living Atlas. Type "world soils soilgrids" in the search box, browse to the layer then click OK.In ArcGIS Pro you can use the built-in raster functions or create your own to create custom extracts of the data. Imagery layers provide fast, powerful inputs to geoprocessing tools, models, or Python scripts in Pro.Online you can filter the layer to show subsets of the data using the filter button and the layer's built-in raster functions.This layer is part of the Living Atlas of the World that provides an easy way to explore the landscape layers and many other beautiful and authoritative maps on hundreds of topics.More information about soilgrids layersAnswers to many questions may be found at soilgrids.org (ISRIC) frequently asked questions (faq) page about the data.To make this layer, Esri reprojected the expected value of ISRIC soil grids from soilgrids' source projection (goode's land WKID 54052) to web mercator projection, nearest neighbor, to facilitate online mapping. The resolution in web mercator projection is the same as the original projection, 250m. But keep in mind that the original dataset has been reprojected to make this web mercator version.This multidimensional soil collection serves the mean or expected value for each soil variable as calculated by soilgrids.org. For all other distributions of the soil variable, be sure to download the data directly from soilgrids.org. The data are available in VRT format and may be converted to other image formats within ArcGIS Pro.Accessing this layer's companion uncertainty layerBecause data quality varies worldwide, the uncertainty of the predicted value varies worldwide. A companion uncertainty layer exists for this layer which you can use to qualify the values you see in this map for analysis. Choose a variable and depth in the multidimensional settings of your map client to access the companion uncertainty layer.

As part of the NERP TE project 2.3 temperature loggers were deployed at 15 sites across Torres Strait to measure the sea temperature. The loggers regularly measure the sea water temperature and record it in their memory. Every year or so the loggers are swapped with new loggers and the recorded data is extracted and recorded in the AIMS Real Time Data Systems database as part of the Australia wide Sea Temperature Observing System. While these loggers do not provide real time data, they provide a vital historical record of conditions across Torres Strait allowing researchers to better understand potential temperature thresholds that might cause coral bleaching and to calibrate satellite measurements of sea temperature. At each site loggers were placed at two depths and were located close to islands or cays to facilitate easy maintenance and replacement. This dataset contains the locations of loggers that may not have been recollected from the field yet. Logger data access: The data from the retrieved data loggers can be accessed by following the link to the "Logger metadata and data tool" associated with each island. These pages can also be accessed via the interactive map showing the retrieved data. Each site on this map contains a link to the associated metadata and data access for that site. Format: 1 shapefile, 2 interactive maps. A shapefile and its interactive map showing the Torres Strait temperature data logger deployed sites. The associated data contains links to pdf files showing the data loggers and their position information. An interactive map providing access to the retrieved data from the Torres Strait temperature data loggers.

The Tisbury zoning GIS feature layer was created from on-screen digitizing of the official Tisbury Zoning map to the FY20 parcel lines. The GIS work was completed by the Martha's Vineyard Commission. The 'official Tisbury Zoning map' was created by Schoefield Barbini & Hone to the best of their ability based on the information they had at that time. Please visit the Town's website for their zoning bylaws.The overlay zoning districts are described within the Town's zoning bylaws. Some overlay zones are regarded as DCPCs (Districts of Critical Planning Concern). DCPCs are initially created and adopted by the Martha's Vineyard Commission (MVC) (the regional planning agency for Dukes County) and then adopted by the Town. The Town may choose to amend the language adopted by the MVC but only to make it more restrictive. Some overlay zones are enforced by the Board of Health and language for those zones may not appear in the Town's bylaws.The overlay zones have been compiled by the MVC from a variety & vintages of basemaps over the years based on the language within the Town's bylaws. See the attributes in the feature layer for date of last GIS edit and notes regarding compilation.The Town's parcel data is compiled by CAI Technologies per the MassGIS Level 3 parcel data standard. These data are then delivered to MassGIS for public sharing. The parcel data layer within this webmap is a direct feed from the MassGIS ArcGIS OnLine cloud. Whenever MassGIS pushes an update of the Tisbury parcels to the AGOL cloud, the parcel bounds within this webmap will automatically reflect the latest update.The property information associated with the parcel bounds is a static export and only updated at the time the parcel bounds are updated by CAI Technologies. For the most current property information, please see the Assessor's online parcel property interactive map. This website is maintained by CAI Technologies per their contract with the Town.

All datasets and products specific to the Steptoe Valley model area. Includes a packed ArcMap project (.mpk), individually zipped shapefiles, and a file geodatabase for the northern Steptoe Valley area; a GeoSoft Oasis montaj project containing GM-SYS 2D gravity profiles along the trace of our seismic reflection lines; a 3D model in EarthVision; spreadsheet of links to published maps; and spreadsheets of well data. Geodatabase (.gdb) containing: 1) A polyline shapefile of basin depth contours clipped to the Steptoe Valley basin, 2) a point shapefile of geologic attitudes covering the SW 1/4 of the model area (from existing pub: NBMG M35), 3) miscellaneous rock unit data, 4) a clipped and re-projected point shapefile of well collars in the Steptoe Valley model area, derived from published well collar datasets available in NBMG M162 (see links spreadsheet), and an interactive map of Nevada geothermal wells (NBMG website).

This dataset contains 63 shapefiles that represent the areas of relevance for each research project under the National Environmental Science Program Marine and Coastal Hub, northern and southern node projects for Rounds 1, 2 & 3.

Methods: Each project map is developed using the following steps: 1. The project map was drawn based on the information provided in the research project proposals. 2. The map was refined based on feedback during the first data discussions with the project leader. 3. Where projects are finished most maps were updated based on the extents of datasets generated by the project and followup checks with the project leader.

The area mapped includes on-ground activities of the project, but also where the outputs of the project are likely to be relevant. The maps were refined by project leads, by showing them the initial map developed from the proposal, then asking them "How would you change this map to better represent the area where your project is relevant?". In general, this would result in changes such as removing areas where they were no longer intending research to be, or trimming of the extents to better represent the habitats that are relevant.

The project extent maps are intentionally low resolution (low number of polygon vertices), limiting the number of vertices 100s of points. This is to allow their easy integration into project metadata records and for presenting via interactive web maps and spatial searching. The goal of the maps was to define the project extent in a manner that was significantly more accurate than a bounding box, reducing the number of false positives generated from a spatial search. The geometry was intended to be simple enough that projects leaders could describe the locations verbally and the rough nature of the mapping made it clear that the regions of relevance are approximate.

In some cases, boundaries were drawn manually using a low number of vertices, in the process adjusting them to be more relevant to the project. In others, high resolution GIS datasets (such as the EEZ, or the Australian coastline) were used, but simplified at a resolution of 5-10km to ensure an appopriate vertices count for the final polygon extent. Reference datasets were frequently used to make adjustments to the maps, for example maps of wetlands and rivers were used to better represent the inner boundary of projects that were relevant for wetlands.

In general, the areas represented in the maps tend to show an area larger then the actual project activities, for example a project focusing on coastal restoration might include marine areas up to 50 km offshore and 50 km inshore. This buffering allows the coastline to be represented with a low number of verticies without leading to false negatives, where a project doesn't come up in a search because the area being searched is just outside the core area of a project.

Limitations of the data: The areas represented in this data are intentionally low resolution. The polygon features from the various projects overlap significantly and thus many boundaries are hidden with default styling. This dataset is not a complete representation of the work being done by the NESP MaC projects as it was collected only 3 years into a 7 year program.

Format of the data: The maps were drawn in QGIS using relevant reference layers and saved as shapefiles. These are then converted to GeoJSON or WKT (Well-known Text) and incorporated into the ISO19115-3 project metadata records in GeoNetwork. Updates to the map are made to the original shapefiles, and the metadata record subsequently updated.

All projects are represented as a single multi-polygon. The multiple polygons was developed by merging of separate areas into a single multi-polygon. This was done to improve compatibility with web platforms, allowing easy conversion to GeoJSON and WKT.

This dataset will be updated periodically as new NESP MaC projects are developed and as project progress and the map layers are improved. These updates will typically be annual.

USDA Wildfire Risk to Communities ViewerThis web-based tool assesses a community’s wildfire risk. The user is able to visualize areas at risk through a series of charts and maps, and data and maps can be downloaded and printed. Additionally, resources are provided for communities to manage and mitigate risk.Wildfire Risk to Communities is a free, easy-to-use website with interactive maps, charts, and resources to help communities understand, explore, and reduce wildfire risk. It was created by the USDA Forest Service under the direction of Congress in the 2018 Consolidated Appropriations Act (H.R. 1625, Section 210). As wildfires increase in frequency and severity across the country, Wildfire Risk to Communities uses the best available science to not only identify risk, but also provide resources for communities to manage and mitigate risk.

This layer provides a darker version of multi-directional hillshade, generated dynamically using a server-side custom function on the World Elevation Terrain layer. It complements the lighter version of Multi-Directional Hillshade function. The z factor is varied based on scale to generate an appropriate visualization at all scales. This layer is useful for visualization of the Terrain and is suitable to use as backdrop for thematic content in web applications and maps. For more information about uses, refer Introducing Dark Hillshade.Note: If you intend to use it as basemap, consider using the tiled version of this service i.e. World Hillshade (Dark), which provides fast and performant rendering.Update Frequency: QuarterlyCoverage: World/GlobalData Sources: This layer is compiled from a variety of best available sources from several data providers. To see the coverage and extents of various datasets comprising this service in an interactive map, see World Elevation Coverage Map.

What can you do with this layer?

Use for Visualization: Yes. Dark Multi-Directional Hillshade provides a quick indication of the shape of the terrain at a range of map scales. The image service can be added to web applications or other maps to enhance contextual understanding. For basemap needs, use World Hillshade (Dark) instead.

Use for Analysis: No. A hillshade is generally not used for analysis.This layer is part of a larger collection of elevation layers that you can use to perform a variety of mapping analysis tasks.
