Remote Sensing Capturing information about the earth from a distance. Methods for remote sensing include aerial photography, radar and satellite imaging. Remote sensing is a common method of building a GIS data base. Resampling The process of reducing or increasing an image data set size by representing a number of pixels with a single pixel or by increasing an image data set size by representing a single pixel with a number of pixels. The overall pixel count, and the resulting file size, are either lowered or increased with this procedure, though the image geographic extent is retained.
Resampled images using reduction are coarser than the original image and thus have less information.
Resampled images using an increase in pixel count appear less course than the original image, but they do not inherently hold any more information. Resampling is not supported in ArcView. Rubber Sheeting A procedure to adjust coverage features in a non-uniform manner. See also Rectification. Satellite Image A picture of the earth taken from a satellite.
