What kinds of web map images are available?

Most web map services can provide a variety of aerial views. The 3 most universal aerial image views are:

  • Base map layer (a plain aerial view of an area on the planet)
  • Road layer (shows the location of roads)
  • Hybrid layer (shows a combination of aerial images combined together in one web map image, i.e. both a basic aerial image with roads overlaid onto that image).

What is “ortho imagery?”

Ortho imagery is web map imagery of the earth from an overhead view that has been geometrically corrected to adjust for the tilt of the camera or lens, and any distortion.
