All of the attributes from the input and overlay layer will be carried over to the result layer. The type of result features will depend on the overlay method and inputs. The features or portions of features in the input layer that do not overlap with the areas in the overlay layer. The input and overlay areas are combined. The dimension of the output geometry type must be the same or less than both the input and overlay dimensions, where Points=0 dimensions, Lines=1 dimension, and Areas=2 dimensions. You can specify the type of output as Points, Lines, or Areas when intersecting line or area features. The features or portions of features in the input that are overlapped with the overlay features are kept. An area feature can be erased by area features.A line feature can be erased by line or area features.A point feature can be erased by point, line, or area features. ![]() The following erase options are supported: When using the Erase overlay method, the input features must be of the same or lesser order feature type of the overlay layer. The availability of overlay method options depends on whether the input and overlay layers are points, lines, or areas. The Overlay Layers tool requires two inputs: an input layer and an overlay layer. See the Site a new hospital lesson for the complete workflow. ![]() Buffers and drive times are used to create layers based on the stated criteria, and Overlay Layers is used to combine the layers to determine which areas meet all the criteria. The site must be within two miles of urban areas, be more than a 20-minute drive from the current main hospital, and be within one mile of main roads. The Loudoun County Board of Supervisors is searching for a suitable location for a new hospital. See the Use species distribution patterns to assess protected areas lesson for the complete workflow. Overlay Layers is used to clip the species data to a specific study area, such as countries in Africa. GIS analysts with the project use spatial analysis to determine which habitats should be protected based on their species diversity and rarity. The Half-Earth Project is working to conserve half the earth's land and sea in order to protect enough habitat for 85 percent or more of Earth's species. The Overlay Layers tool combines two layers into a single layer using one of three methods: Intersect, Union, or Erase. To learn more, see Overlay Layers ( Map Viewer). This tool is now available in Map Viewer, the modern map-making tool in ArcGIS Online. ![]()
