Index Map
A map showing the location and extent of individual map sheets within a larger area, aiding in spatial data organization and retrieval (inferred from standard GIS usage).
What is an Index Map?
A reference map called an index map is used to arrange, find, and give a summary of a group of map sheets or data layers. Particularly in extensive mapping projects, it serves as a guide to illustrate the arrangement of individual map tiles or datasets.
Essential components of an index map:
Shows the grid arrangement of data tiles or map sheets.
Assists customers in finding the appropriate map sheet according to their location.
Frequently include names, codes, or sheet numbers for convenient access.
Frequently found in aerial image collections, cadastral maps, and topographic maps
Index maps are crucial for efficiently organizing spatial data across many regions or topics and exploring big datasets in GIS.
