Overview of Weighted Site Selection and Suitability Analysis

Site selection is a type of analysis used in GIS to determine the best place or site for something. Weighted site selection analysis is one type of site selection that allows users to rank raster cells and assign a relative importance value to each layer. This article examines weighted site selection by explaining how it works and when it should be used. It also provides an example of a weighted site selection project for reference.

Common Map Projections

Selecting the right map projection is one of the important first considerations for accurate GIS analysis. Reviewed here are the Robinson, Transverse Mercator, Lambert Conformal Conic, and Space Oblique Mercator projections

The Power of Mapping

The real value of GIS come from the ability to integrate spatial information with higher end statistical and analytical processes to derive spatial patterns not readily apparent to the observer.
