MyGeoHub is a science gateway for researchers working with geospatial data. Based on the HUBzero cyberinfrastructure framework, it provides general-purpose software modules enabling geospatial data management, processing and visualization. Termed “GABBs” (Geospatial Data Analysis Building Blocks), these modules can be leveraged to build geospatial data driven tools with minimal programming and construct dynamic workflows chaining both local and remote tools and data sources. We will present examples of such end-to-end workflows demonstrating the underlying software building blocks that have also found use beyond the MyGeoHub gateway in other science domains.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. Following the vegetation plot data analysis, the preliminary vegetation map was edited and refined to produce a revised preliminary vegetation map prior to thematic accuracy assessment. Using ArcMap 9.2 (ESRI 1999-2006), polygon boundaries were revised on screen based on the plot data, field observations, classification analyses, aerial photography signatures, and topographic maps. Each polygon was assigned the NVC Community Element Global (CEGL) code of a preliminary vegetation association based on the information sources listed above. Second, third, and fourth CEGL code choices were entered in cases of uncertainty, or for polygons representing mosaics of two or more types.

Tags are part of the information, commonly called metadata, that can be added when creating new items, authoring maps and apps, or creating new groups in your organization. They can be added to any item, can be edited, and are a useful way to boost search results and find specific content.Without proper forethought, tagging data will quickly become a subjective process with a mess of inconsistent tags existing within an organization. When sharing data publicly over a multi-organizational open data platform such as the Florida Geospatial Open Data Portal, these tags may be incompatible with tags used by other organizations.This webpage seeks to provide guidance to State of Florida organizations that participate in the Florida Geospatial Open Data Portal by highlighting how tagging data works in the ArcGIS Online platform, providing best practices for getting started tagging data in your own organization, and explaining how tagging works with the Florida Geospatial Open Data Portal.

It can therefore overlap impervious layers.High vegetation is distinguished from low vegetation based on crown, texture, and derived height models. Leveraging stereo imagery produces results using 3D elevation models used to aid the distinction of vegetation categories. Distinguishing low from high vegetation is based on a 5m threshold, but this is not always feasible, especially in areas where heavy canopy prevents a visualization of the ground. In these circumstances, high vegetation will be given the priority over low vegetation.

To improve public health and the environment, the United States Environmental Protection Agency (EPA) collects information about facilities, sites, or places subject to environmental regulation or of environmental interest. Through the Geospatial Data Download Service, the public is now able to download the EPA Geodata Shapefile, Feature Class or extensible markup language (XML) file containing facility and site information from EPA's national program systems. The files are Internet accessible from the Envirofacts Web site (https://www3.epa.gov/enviro/). The data may be used with geospatial mapping applications. (Note: The files omit facilities without latitude/longitude coordinates.) The EPA Geospatial Data contains the name, location (latitude/longitude), and EPA program information about specific facilities and sites. In addition, the files contain a Uniform Resource Locator (URL), which allows mapping applications to present an option to users to access additional EPA data resources on a specific facility or site.

The portal hosts a wide range of data and information as well as providing map services that allow visitors to see and use the data on their own computers.
It is a significant step toward the long-term SDI goal of establishing a network of seamlessly inter-operable agency nodes for geospatial data. Acting as a data clearinghouse, the portal is a common repository for our stakeholders' data and also hosts data for those agencies not yet able to implement and administer their own node.
The portal acts as a gateway to an extensive metadata catalog--this is a master inventory where users can find standard information about available geographic data sets. The data sets are generated by our stakeholders, the Abu Dhabi government agencies that develop and maintain the most commonly needed fundamental geographic data in the Emirate.

Science gateways are becoming an integral component of modern collaborative research. They find widespread adoption by research groups to share data, code and tools both within a project and with the broader community. Sustainability beyond initial funding is a significant challenge for a science gateway to continue to operate, update and support the communities it serves. MyGeoHub.org is a geospatial science gateway powered by HUBzero. MyGeoHub employs a business model of hosting multiple research projects on a single HUBzero instance to manage the gateway operations more efficiently and sustainably while lowering the cost to individual projects. This model allows projects to share the gateway’s common capabilities and the underlying hardware and other connected computing resources, and continued maintenance of their sites even after the original funding has run out allowing time for acquiring new funding. MyGeoHub has hosted a number of projects, ranging from hydrologic modeling and data sharing, plant phenotyping, global and local sustainable development, climate variability impact on crops, and most recently, modeling of industry processes to improve reuse and recycling of materials. The shared need to manage, visualize and process geospatial data across the projects has motivated the Geospatial Data Building Blocks (GABBs) development funded by NSF DIBBs. GABBs provides a “File Explorer” type user interface for managing geospatial data (no coding is needed), a builder for visualizing and exploring geo-referenced data without coding, a Python map library and other toolkits for building geospatial analysis and computational tools without requiring GIS programming expertise. GABBs can be added to an existing or new HUBzero site, as is the case on MyGeoHub. Teams use MyGeoHub to coordinate project activities, share files and information, publish tools and datasets (with DOI) to provide not only easy access but also improved reuse and reproducibility of data and code as the interactive online tools and workflows can be used without downloading or installing software. Tools on MyGeoHub have also been used in courses, training workshops and summer camps. MyGeoHub is supporting more than 8000 users annually.

This NYC Reservoirs Watershed Areas (HUC 12) GIS layer was derived from the 12-Digit National Watershed Boundary Database (WBD) at 1:24,000 for EPA Region 2 and Surrounding States. HUC 12 polygons were selected from the source based on interactively comparing these HUC 12s in our GIS with images of the New York City's Water Supply System Map found at http://www.nyc.gov/html/dep/html/drinking_water/wsmaps_wide.shtml. The 12 digit Hydrologic Units (HUCs) for EPA Region 2 and surrounding states (Northeastern states, parts of the Great Lakes, Puerto Rico and the USVI) are a subset of the National Watershed Boundary Database (WBD), downloaded from the Natural Resources Conservation Service (NRCS) Geospatial Gateway and imported into the EPA Region 2 Oracle/SDE database. This layer reflects 2009 updates to the WBD that included new boundary data for New York and New Jersey.

Science gateways are generally accessed via web browsers from workstation or laptop computers. However, activities such as fieldwork and data collection have prompted an increasing call for new methods of access using a wide range of mobile and specialized devices. Our work to extend the HUBzero gateway framework with new access routes is described. Specifically, an emphasis is placed on enabling the flow of geospatial data and metadata between geo-enhanced HUBzero hubs and devices in the field.
