This layer provides slope values in degrees calculated dynamically from the elevation data (within the current extents) using the server-side slope function applied on the Terrain layer. The values are integer and represent the angle of the downward sloping terrain (0 to 90 degrees). Note: slope is a function of the pixel size of the request, so at smaller scales the slope values are smaller as pixel sizes increase. Units: DegreesUpdate 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.WARNING: Slope is computed in the projection specified by the client software. The server resamples the elevation data to the requested projection and pixel size and then computes slope. Slope should be requested in a projection that maintains correct scale in x and y directions for the area of interest. Using geographic coordinates will give incorrect results. For the WGS84 Mercator and WGS Web Mercator (auxiliary sphere) projections used by many web applications, a correction factor has been included to correct for latitude-dependent scale changes.What can you do with this layer?Use for Visualization: No. This image service provides numeric values indicating terrain characteristics. Due to the limited range of values, this service is not generally appropriate for visual interpretation, unless the client application applies an additional color map.

This data set represents a 5-meter resolution LiDAR-derived percent slope layer for New Hampshire. It was generated from a statewide Esri Mosaic Dataset which comprised 8 separate LiDAR collections that covered the state as of January, 2020. The Mosaic Dataset was used as input to the ArcGIS Spatial Analyst "Slope" geoprocessing tool which calculates the percent slope for each cell of the input raster, in this case, the statewide mosaic dataset.
Open the Data Resource: https://doi.org/10.5066/P9EJ6PGT The marsh-forest boundary in the Chesapeake Bay was determined by geoprocessing high-resolution (1 square meter) land use and land cover data sets. Perpendicular transects were cast at standard intervals (30 meters) along the boundary within a GIS by repurposing the Digital Shoreline Analysis System (DSAS) Version 5.0, an ArcGIS extension developed by the U.S. Geological Survey. Average and maximum slope values were assigned to each transect from surface elevation data. The same values were also provided as points at the center of the transect where it crossed over the boundary. The slope values across the marsh-forest transition zone and at the boundary itself provide comprehensive data layers for local, state and federal managers to improve understanding of salt marsh migration. This additionally aids the U.S. Geological Survey in its effort to assess the coastal vulnerability and response of salt marsh ecosystems, including the Chesapeake Bay region.

Raster functions are operations that apply processing directly to raster dataset pixels. The raster functions supplied here are the same operations applied to the 3 ft. DEM-related web services from NC OneMap (Aspect, Hillshade, Shaded Elevation, Shaded Relief, Slope, and raster contours for 1 foot, 2 feet, 4 feet, 20 feet, and 100 feet). The downloaded functions can be used in ArcGIS products.
These could be helpful if there is a need to use an NC OneMap DEM-derivative elevation product in a disconnected environment, an instance where web service use is not practical. The county-based DEMs can be downloaded and the raster functions applied in ArcGIS Pro, for use in an offline environment.
In the downloaded raster functions ZIP file are XML files for:
Aspect
Hillshade
Shaded Elevation
Shaded Relief
Slope
Raster Contours for intervals: 1 ft., 2 ft., 4 ft., 20 ft., 100 ft.
Information on using raster functions in ArcGIS Pro can be found here.
This dataset identifies areas with steep slopes in two categories used in local planning agencies: slopes 15-25% and slopes over 25% (slope=rise/run).

This layer provides slope percent rise values calculated dynamically from the elevation data (within the current extents) using the server-side slope function applied on the Terrain layer. Percent of slope is determined by dividing the amount of elevation change by the amount of horizontal distance covered (sometimes referred to as "the rise divided by the run"), and then multiplying the result by 100. The values range from 0 to essentially infinity. When the slope angle equals 45 degrees, the rise is equal to the run. Expressed as a percentage, the slope of this angle is 100 percent. As the slope approaches vertical (90 degrees), the percentage slope approaches infinity.Units: Percent (%)Update Frequency: QuarterlyCoverage: World/GlobalData Sources: This layer is compiled from a variety of best available sources from several data providers.

Dewberry collected LiDAR for ~3,942 square miles in various Virginia, West Virginia, and Maryland Counties. The acquisition was performed by Geodigital. This metadata covers the LiDAR produced for the Fairfax, Fauquier, Frederick, and Jefferson County project area. The nominal pulse spacing for this project is 1.6 ft (0.5 meters). This project was collected with a sensor which collects intensity values for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to contract specifications: 1-Unclassified, 2-Ground, 7-Noise, 9-Water, 10-Ignored Ground due to breakline proximity, and 11-Withheld. Dewberry produced 3D breaklines and combined these with the final LiDAR data to produce seamless hydro flattened DEMs for the 2150 tiles (1500 m x 1500 m) that cover this deliverable.This is a MD iMAP hosted service.

Steep slopes for Anne Arundel County, MD. This dataset was created using ESRI's ArcGIS 10.7.1 with the Spatial Analyst extension. The source data was the County's 2020 Digital Elevation Model with a 1 foot resolution. The "Slope" command was used against the DEM to create a raster dataset with slope classifications based on the County Code (15 - 24.99%, 25% and greater). The raster dataset was then converted to a vector dataset by using the "Extract by Attribute" raster tool for both "15 to 25%" and "25% and greater". These two datasets were then merged together. Please download the shapefiles for the area of interest based on image below.Area 1, Area 2, Area 3, Area 4, Area 5Area 6, Area 7, Area 8, Area 9, Area 10Area 11, Area 12

This SRTM Slope Map was created from level 1 SRTM NASA data which was cleaned and had holes patched. The slope map was created in ArcMap (presumably using the simple 3x3 nearest neighbour method). The data does not include the Shetland Islands as SRTM data becomes unreliable at 60N. The cell size is close to 90m. Data was acquired between the 11th - 20th Feb 2000. SRTM Slope Map was created from level 1 SRTM NASA data, slope map generated in ArcGIS using a basic nearest neighbour approach. Digital Terrain Model. This dataset was first accessioned in the EDINA ShareGeo Open repository on 2010-06-30 and migrated to Edinburgh DataShare on 2017-02-20.
The slope image in this tile service from MassGIS shows the variation in elevation (steepness), expressed in degrees (0 is flat, 89 is nearly vertical). A 3X3 window was used to calculate the slope at each pixel. Darker areas represent steeper slopes.For more information, see MassGIS' Lidar Terrain Data page.
The digital maps presented here were originally published as hard copy maps in the Coastal Zone Atlas of Washington between 1978 and 1980. Although the Atlas has been out of print for many years, the maps contain information that remain the basis for local planning decisions. After receiving multiple requests for electronic versions of portions of the Atlas, an effort was made to scan, georeference and digitize aspects of the Atlas, beginning with the slope stability maps. These maps indicate the relative stability of coastal slopes as interpreted by geologists based on aerial photographs, geological mapping, topography, and field observations. Such methods are standard, but may occasionally result in some unstable areas being overlooked and in some stable areas being incorrectly identified as unstable. Further inaccuracies are introduced to the data through the process of converting the published maps into digital format. Important land use or building decisions should always be based on detailed geotechnical investigations. This mapping represents conditions observed in the early and mid-1970s. Shorelines and steep slopes are dynamic areas and many landslides have occurred since that time that are not reflected on these maps. Subsequent human activities may have increased or decreased the stability of some areas.
This map provides a colorized representation of slope, generated dynamically using server-side slope function on the Terrain layer.
