Welcome to the Imagery and Elevation Services knowledge base for the Spatial Portal. The Spatial Portal is a collection of spatial web services from a variety of categories. This site is written for users of Imagery and Elevation Services. These services can be accessed in an online map viewer and GIS client software.
The Imagery and Elevation services cater to both public and restricted users. Publicly-accessible services are free to use and can be connected to a GIS software. Restricted services contain the most recent imagery acquired through the Spatial Imagery Services Program (SISP).
