1. Native GIS formats
Other GIS formats may need to be converted to a common format to be truly compatible.
Non-traditional GIS datasets
These may include such items as digital terrain data, orthophotographs, and satellite imagery. These data may provide tremendous capability, but must be managed in ways different from traditional vector information. Conversion to a standard format is relatively straightforward. The new high-resolution satellites with high spectral and spatial definition are often difficult to view and render with commonly available tools.
Digital data already in tabular form integrate into the GIS database in two very important ways. First, they form the basis for GIS feature attributes. In this case they must be linked somehow to the objects forming the spatial geometry. If a common key is available the linkage becomes relatively straightforward, but if not the problem becomes significantly more complex. Second, they are the basis for the spatial objects themselves. Coordinates stored in a tabular form may be extracted and converted to a common coordinate system, then linked to whatever other attribute information is contained within the table.
Items in analog (paper) form such as reports, maps, or charts, involve the most effort in terms of data conversion - these data must be keypunched, manually digitized, scanned, or otherwise automated to suit the demands made of them. Report data become digital tables, which then assume the characteristics of that item discussed above. Maps and charts should realistically be digitized into the preferred GIS format, if possible, to avoid the other issues associated with the non-preferred formats.
