This map provides a hillshaded surface generated dynamically using a multi-directional hillshade server-side custom function on the World Elevation Terrain layer. This algorithm computes hillshade from six different directions, where each hillshade is multiplied by a weight and thereafter the sum of all is normalized to produce the final output. The z factor is varied based on scale so that a suitable hillshade is visible at all scales. This layer is useful for visualization of the Terrain because it is easy to interpret and use as a base layer in applications and maps.For more information about uses, refer Introducing Esri’s Next Generation Hillshade.What can you do with this layer?Use for Visualization: Yes. 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.Use for Analysis: No. A hillshade is generally not used for analysis.Note: If you intend to use it as basemap, consider using the tiled version of this service i.e. World Hillshade, which provides fast and performant rendering.Data Sources and Coverage: 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 Elevation Coverage Map.This layer is part of a larger collection of elevation layers that you can use to perform a variety of mapping analysis tasks.

This data set represents smoothed, 2-foot bare earth contours (isolines) for the Ossipee Lake (0106000208) HUC 10 unit. It was derived from a data set which was compiled from LIDAR collections in NH available as of spring, 2019. The raster was filtered using the ArcGIS FOCAL STATISTICS tool with a 3x3 circular neighborhood. The contours were generated using the ArcGIS CONTOUR tool while applying a Z factor of 3.2808 to convert the elevation values from meters to feet. The filtered contours were then smoothed using the ArcGIS SMOOTH LINE tool. The data include an INDEX field with values of 10 and 100 to flag 10 and 100-foot contours. Note on HUC 01060000310: Due to limitations in the source LIDAR data, some anomalies exist in the generated contours in coastal areas of the state. These were left in the data so that users can determine what further processing best meets their application needs.
