Created through export from Public Layers, addition from raster and vector geospatial files stored locally or found online, from heads-up digitizing, and/or from XY data organized in tables, geospatial layers have the greatest ability to be symbolized, analyzed, and modified.

When logged in as an eRAMS user, geospatial layers are displayed under the User and/or Project tabs. Files under the User tab are available for use in any project, whereas files under the Project tab are only available for use in the current project.
