Table 1 Estimated growth in GIS sales and revenues
At the moment there is large demand for tire products and
services of the GIS industry, and GIS is undergoing tremendous
growth (Table 1).
Another index of the growth in the spatial data industry is the
number of new software packages released onto the market
(Figure 2). GIS and remote sensing activity is continuing to
expand in response to regional and global environmental
problems (i.e. rising populations and shrinking resources), as
well as demand from specialised marketing services and
delivery' of human services. Thus, GIS technology is a rapidly
growing service sector industry, and remote sensing is a spatial
data input to GIS.
