Geographic Information Systems (GIS) and Imagery Approach to Historical Urban Growth Trends Around Military Installations

摘要

Recent advances in computer analysis techniques based on remotely sensed satellite images can be used with other geographic information systems (GIS) data to establish a scientifically derived baseline of growth near military installations. Developing such a trend analysis is one step in support of a military initiative to identify and mitigate pressure on its military mission activities due to the development or placement of land uses near installation boundaries. The new land uses, often described as 'encroachment,' may in some way conflict with the ongoing activities at an installation. This study documents a unique procedure called 'CellPicker' to generate land cover changes using satellite images and contextual GIS data for the each decade beginning in the 1970s.
