Geographic Similarity - Finding that which is hidden
Track: Modeling Techniques
Authors: Elizabeth Hayes

Geographic Similarity is an analysis technique to look for people or things that wish to remain hidden.

After finding items of interest, one may identify the best places to look for similar items by taking principal components of the thematic layers where they were found, and using linear regression to identify the most closely matched terrain.

Geographic Similarity was pioneered by archeologists, but it’s widely used in other fields such as ecology and, in our case, military intelligence.
