The Viewshed analysis layer is used to identify visible areas. You specify the places you are interested in, either from a file or interactively, and the Viewshed service combines this with Esri-curated elevation data to create output polygons of visible areas. Some questions you can answer with the Viewshed task include:What areas can I see from this location? What areas can see me?Can I see the proposed wind farm?What areas can be seen from the proposed fire tower?The maximum number of input features is 1000.Viewshed has the following optional parameters:Maximum Distance: The maximum distance to calculate the viewshed.Maximum Distance Units: The units for the Maximum Distance parameter. The default is meters.DEM Resolution: The source elevation data; the default is 90m resolution SRTM. Other options include 30m, 24m, 10m, and Finest.Observer Height: The height above the surface of the observer. The default value of 1.75 meters is an average height of a person. If you are looking from an elevation location such as an observation tower or a tall building, use that height instead.Observer Height Units: The units for the Observer Height parameter. The default is meters.Surface Offset: The height above the surface of the object you are trying to see. The default value is 0. If you are trying to see buildings or wind turbines add their height here.Surface Offset Units: The units for the Surface Offset parameter. The default is meters.Generalize Viewshed Polygons: Determine if the viewshed polygons are to be generalized or not. The viewshed calculation is based upon a raster elevation model which creates a result with stair-stepped edges. To create a more pleasing appearance, and improve performance, the default behavior is to generalize the polygons. This generalization will not change the accuracy of the result for any location more than one half of the DEM's resolution.By default, this tool currently works worldwide between 60 degrees north and 56 degrees south based on the 3 arc-second (approximately 90 meter) resolution SRTM dataset. Depending upon the DEM resolution pick by the user, different data sources will be used by the tool. For 24m, tool will use global dataset WorldDEM4Ortho (excluding the counties of Azerbaijan, DR Congo and Ukraine) 0.8 arc-second (approximately 24 meter) from Airbus Defence and Space GmbH. For 30m, tool will use 1 arc-second resolution data in North America (Canada, United States, and Mexico) from the USGS National Elevation Dataset (NED), SRTM DEM-S dataset from Geoscience Australia in Australia and SRTM data between 60 degrees north and 56 degrees south in the remaining parts of the world (Africa, South America, most of Europe and continental Asia, the East Indies, New Zealand, and islands of the western Pacific). For 10m, tool will use 1/3 arc-second resolution data in the continental United States from USGS National Elevation Dataset (NED) and approximately 10 meter data covering Netherlands, Norway, Finland, Denmark, Austria, Spain, Japan Estonia, Latvia, Lithuania, Slovakia, Italy, Northern Ireland, Switzerland and Liechtenstein from various authoritative sources.To learn more, read the developer documentation for Viewshed or follow the Learn ArcGIS exercise called I Can See for Miles and Miles.

This hosted feature layer has been published in RI State Plane Feet NAD 83.The Urban Services Boundary was developed for the Rhode Island Statewide Planning Program as part of a GIS overlay analysis of land suitability and availability for Figure 121-02-(01), Rhode Island Future Land Use Map - 2025 of the Land use 2025: State Land Use Policies and Plan. This is the State of Rhode Island"s plan for conservation and development in the 21st century. The boundary represents the general extent of the areas within which public services supporting urban development presently exist, or are likely to be provided, through 2025. Within the boundary most land should be served by public water service and many areas will have public sewer service available as well. Public transit service should be generally available. Several watersheds and other sensitive resource areas were excluded from the boundary, indicating that protection of the resources involved must be a principle concern limiting future development intensity potential. Also included within the boundary, are other undeveloped areas which will have lower development intensities due to the presence of resources constraints and or limited infrastructure.The Land use 2025: State Land Use Policies and Plan, was published by the Rhode Island Statewide Planning Program on April 13, 2006. The intent of the Urban Services Boundary is to provide an indication for planning purposes of areas where a higher level of public services is anticipated to be available to accommodate more intensive development and redevelopment. Public services in areas outside the Urban Services Boundary are anticipated to be more limited, and planned development intensities should be lower. The Plan directs the state and communities to concentrate growth inside the boundary and within locally designated centers in rural areas, and to pursue different development approaches for urban and rural areas. The Future Land Use Map with the Urban Services Boundary describes the recommended 2025 future land use pattern for the State of Rhode Island. This map has several purposes and applications: It is intended as a policy guide for directing growth to areas most capable of supporting current and future developed uses (and conversely, away from areas less suited for development). In this regard, it is intended to inform state and local capital investment decisions so that investments may target and support growth in appropriate areas and discourage growth in inappropriate locations. Secondly, the Future Land Use Map is a guide to assist the state and communities in making land use policies. It is important to note the Map is a generalized portrayal of state land use policy. IT IS NOT A "STATEWIDE ZONING MAP" - zoning matters and individual land use decisions are the prerogative of local governments.

These data are for use with the Virginia PSAP Boundary Segment Compilation Guidelines available here. Updated data are available from feature services here. Documentation on using feature services is available here.Additional resources and recommendations on GIS related topics are available on the VGIN 9-1-1 & GIS page.

This hosted feature layer has been published in RI State Plane Feet NAD 83. THIS IS A FUTURE LAND USE PLANNING MAP CREATED IN 2006. THIS DOES NOT SHOW CURRENT 2025 LAND USE LAND COVER. The Land Use 2025 dataset was developed for the Division of Planning, RI Statewide Planning Program as part of an update to a state land use plan. It evolved from a GIS overlay analysis of land suitability and availability and scenario planning for future growth. The analysis focused on the 37% of the State identified as undeveloped and unprotected in a land cover analysis from RIGIS 1995 land use land cover data. The project studied areas for suitability for conservation and development, based on the location of key natural resources and public infrastructure. The results identified areas with future use potential, under three categories of development intensity and two categories of conservation.These data are presented in the Plan as Figure 121-02-(01), Future Land Use Map. Land Use 2025: State Land Use Policies and Plan was published by the RI Statewide Planning Program on April 13, 2006. The intent of the Plan is to bring together the elements of the State Guide Plan such as natural resources, economic development, housing and transportation to guide conservation and land development in the State. The Plan directs the state and communities to concentrate growth inside the Urban Services Boundary (USB) and within potential growth centers in rural areas. It establishes different development approaches for urban and rural areas.These data have several purposes and applications: They are intended to be used as a policy guide for directing growth to areas most capable of supporting current and future developed uses and to direct growth away from areas less suited for development. Secondly, these data are a guide to assist the state and communities in making land use policies. It is important to note these data are a generalized portrayal of state land use policy. These are not a statewide zoning data. Zoning matters and individual land use decisions are the prerogative of local governments. The land use element is the over arching element in Rhode Island's State Guide Plan. The Plan articulates goals, objectives and strategies to guide the current and future land use planning of municipalities and state agencies. The purpose of the plan is to guide future land use and to present policies under which state and municipal plans and land use activities will be reviewed for consistency with the State Guide Plan. The Map is a graphical representation of recommendations for future growth patterns in the State. It depicts where different intensities of development (e.g. parks, urban development, non-urban development) should occur by color. The Map contains a USB that shows where areas with public services supporting urban development presently exist, or are likely to be provided, through 2025. Within the USB, most land is served by public water service; many areas also have public sewer service, as well as, public transit. Also included on the map are growth centers which are potential areas for development and redevelopment outside of the USB. Growth Centers are envisioned to be areas that will encourage development that is both contiguous to existing development with low fiscal and environmental impacts.NOTE: These data will be updated when the associated plan is updated or upon an amendment approved by the State Planning Council. NOTE: Wetlands were not categorized within the Land Use 2025 dataset.When using this dataset, the RIGIS wetlands dataset should be overlaid as a mask. Full descriptions of the categories and intended uses can be found within Section 2-4, Future Land Use Patterns, Categories, and Intended Uses, of the Plan. https://www.planning.ri.gov/documents/guide_plan/landuse2025.pdf

Washington State’s Growth Management Act (GMA) (chapter 36.70A RCW) requires the development of a comprehensive plan. Comprehensive Plan {https://www.snohomishcountywa.gov/2139/Comprehensive-Plan} changes are voted on once per year by the Snohomish County Council, with recommendations given by the Planning Commission, Public comments, and the Department of Planning and Development Services (PDS).The Comprehensive Plan serves as the document that guides County decisions and services on a wide range of topics, including: land use, transportation, parks, housing, capital facilities and the natural environment. The Comprehensive Plan consists of five components:The General Policy Plan consists of goals, objectives and policies that serve as a guide to the county’s growth and development.The Future Land Use Map (PDF) expresses graphically the 20-year vision of the preferred land use pattern. It identifies the urban growth areas around cities and towns, as well as urban, rural, and resource lands. The map is implemented through numerous zoning classifications and development regulations.The Transportation Element presents a plan for transportation facilities and services to support the needs of the projected populations.The Capital Facilities Plan (PDF) contains an inventory of the county’s public facilities and utilities, establishes level of service standards necessary to support development, and prioritizes facilities needed to support the needs of the projected populations.The Park and Recreation Element presents a plan for park and recreation facilities and services to support the needs of the projected populations.Outside of the periodic update cycle, less extensive revisions are allowed through the docketing process and County-initiated amendment proposals. Information on current and past proposals, and to find out about submitting an amendment to the Comprehensive Plan can be obtained from the Docket and County-Initiated Amendments web page.

The Growth Centers data on the Future Land Use Map were developed for the Division of Planning, RI Statewide Planning Program as part of an update to a state land use plan. These data are included in the Plan as Figure 121-02-(01), Future Land Use Map. The growth centers were an end product of a GIS overlay analysis of land suitability and scenario planning for future growth. Initially the factors for centers included 9 urban communities; Providence, East Providence, Pawtucket, Cranston, Central Falls, Warwick, West Warwick, Newport and Woonsocket as potential urban centers as opposed to identifying specific neighborhoods in those municipalities. Historical downtowns and traditional mixed-use central business cores in urban fringe / suburban communities were included as potential town centers, as well as, some of the historical village downtowns and some traditional mixed-use cores in rural communities. All communities in the State either include one or more existing or potential centers or are within the Urban Services Boundary on the map. The growth centers shown in these data were selected by the Statewide Planning staff, the Technical Committee and the State Planning Council through a series of discussions at public meetings, and comments received at public hearings and workshops in the final adoption of Land Use 2025 in 2006. Centers depicted on the Future Land Use 2025 map are illustrative of potential new centers that may be established. It is not a intended as a comprehensive inventory of existing centers. Other centers may be illustrated and or proposed in municipal comprehensive plans. Full descriptions of the methodology for the GIS analysis and scenario planning can be found within the Technical Appendix D to Land Use 2025, Geographic Analysis for Land Available and Suitable for Development for Land Use 2025. Land Use 2025: State Land Use Policies and Plan was published by the RI Statewide Planning Program on April 13, 2006. The Plan directs the state and communities to concentrate growth inside the Urban Services Boundary (USB) and within potential growth centers in rural areas. It establishes different development approaches for urban and rural areas. This Map has several purposes and applications: It is intended to be used as a policy guide for directing growth to areas most capable of supporting current and future developed uses and to direct growth away from areas less suited for development. Secondly, the Map is a guide to assist the state and communities in making land use policies. It is important to note the Map is a generalized portrayal of state land use policy. It is not a statewide zoning map. Zoning matters and individual land use decisions are the prerogative of local governments. Growth Centers are envisioned to be areas that will encourage development that is both contiguous to existing development with low fiscal and environmental impacts. They are intended to be compact developed areas (existing or new) containing a defined central core that accommodate community needs for residential and economic functions. Centers are intended to provide optimum use of land and services, and offer a choice of diverse housing stock, economic functions, and cultural and governmental uses. Density will vary greatly between centers subject to site constraints; however, it is intended that they will share the common characteristic of compact development that capitalizes on existing infrastructure. Centers should reflect traditional New England development patterns with a human scale of blocks, streets, open spaces that offer walkability and access to transit where available. In suburban areas, centers should be distinguished from surrounding sprawling development by a closer proximity between residential and non-residential uses. In rural areas, centers should be surrounded by natural areas, farmland, or open space, and may have a mixed-use and or commercial area in the core for neighborhood-scale goods and services. The land use element is the over arching element in Rhode Island's State Guide Plan. The Plan articulates goals, objectives and strategies to guide the current and future land use planning of municipalities and state agencies. The purpose of the plan is to guide future land use and to present policies under which state and municipal plans and land use activities will be reviewed for consistency with the State Guide Plan. The Map is a graphical representation of recommendations for future growth patterns in the State. The Map contains a USB that shows where areas with public services supporting urban development presently exist, or are likely to be provided, through 2025. Also included on the map are growth centers which are potential areas for development and redevelopment outside of the USB. These data will be updated when plan is updated or upon an amendment approved by the State Planning Council.

This is a polygon data set depicting sites designated by the City of Boise as historic local landmarks and sites registered as historic by the National Register of Historic Places (NRHP) within Boise's Area of Impact. Historic landmarks are defined as sites, buildings, structures or objects that possess exceptional significance in history, architecture, engineering, archaeology or culture at the local level and have been designated as an historic landmark through either the public hearing process as defined by the Boise City Historic Preservation Code, Title 11 Section 05-09 of the City Code, or by being listed on the NRHP. The historic landmark polygons represent the area (building(s), parcel(s), or feature(s)) of historic significance for a given site. This data set was developed by Boise Planning and Development Services (PDS) staff based on available documentation of the landmark's representative area. Historic local landmarks are established by City of Boise ordinances; these sites may or may not also be registered as national historic landmarks. Properties that have historic landmarks present are regulated for all building and demolition permits in order to protect the City's historic resources. This data is updated as changes occur to the national registry and the local landmark listing for Boise.For more information, please visit City of Boise Planning and Development Services.

This feature class is maintained in coordination with the addressing authorities of Thurston County Development Services and the Cities of Olympia, Lacey, Tumwater, Yelm, and Rainier. The intent of this data is to provide emergency services with the earliest address plan for new developments even while the development is under construction.Street centerlines are initially digitized from center of right-of-ways shown on survey plats and are then updated when a new orthophoto becomes available. Unnamed roads, driveways, planned roads, alleys are only intended for graphic display. These segments are generally not topologically connected to addressed streets. This feature class is used as the street centerline source for TCOMM911 Operations Center (CAPCOM) CAD/Ti Geo file load and Maverick Map data. As of 1/06, edits in this data regarding exact street name and begin/end address ranges are also entered in the County's Master Street Address Guide through Intrado's 911Net database maintenance request site.Layer/Field Explanation:Street centerlines are initially digitized from center of right-of-ways shown on preliminary plats and updated in final survey plats. If this source is delivered in hard copy, then the document will be scanned and the image georectified using common parcel corners found in the source and in the County parcel layer. Some centerlines are imported directly from digital survey drawings. When a new orthophoto becomes available, the centerlines are reviewed again and adjusted and/or vertex weeded as necessary.Theoretical address ranges are used to extend valid ranges beyond physical addresses. This will influence the positional quality of geocoded points if used as a reference source. It should be noted that the County Development Services Addressing Department does not assign house numbers where the right two digits exceed the number 49. For emergency services, address ranges need to be continuous where the physical street is continuous and maintain 100 block interval changes at intersections. As a result, geocoded points are likely to be skewed toward the lower end of each address range.Zero address ranges will not be used on any name/addressed street types. Any named and signed road without address ranges will default to a 100-199 address range Speed Limit- This attribute was created using the best available information at the time. Use with caution. Limited access segments (I5 and US 101) have been assigned address ranges based on mile post location. Decimal house numbers are not valid so mile post address ranges have been multiplied by 100.CITY_L and CITY_R are used to define msag community, not postal community. Unincorporated areas and those within the City of Olympia are given the community of 'OL'. A list is posted to the County GeoData Center showing unique street names selected by all jurisdictions within the county for addressing officers to consult in selecting street names, http://www.geodata.org/capcom.aspx. Capcom's policy requires that new street names are unique regardless of jurisdiction and street type. Unnamed roads, unofficially named roads, driveways and alleys are identified as TYPE=5.Special characters in street names are not valid. Hyphens are generally replaced with a space character.Forest roads within Capitol Forest are being captured with proper WA DNR road identification based on DNR map. The address range applied to forest roads is based on distance in miles x 100 from the trunk in which branching road extends.
