Incorporating
Remote Sensing Data into a GIS
Remote sensing and GIS technologies were initially
developed for different purposes. However, both of these
resources can provide information about the earth's
resources. Advancements in computer hardware and software
technology now make it possible for data from these
sources to be easily integrated.
Most GIS software packages allow remotely sensed data
to be imported, or at least viewed, within the software
application. This ability allows the analyst to overlay
remote sensing data layers with other spatial data layers.
Analysts use remotely sensed imagery with GIS data sets
for a variety of reasons, including providing a continuous
regional view of the areas and extracting GIS data layers,
such as contours or building footprints. click
