Exploit information available in a Feature orFeature Collection to derive application-oriented quantitative results that are not available from the raw data itself.

Composed of 9 operations

①Buffering to create a proximity zone②Boolean operations to perform binary operations on two or more features③Determine if any features in the Feature Collection obstruct④Compute non-stored geometric properties⑤Exploiting elevation coverages⑥Create geospatial model of one or more related Feature Collections⑦Interpret feature properties⑧Exploiting transportation routes⑨Computing exposure

Process flow of GSM’s active retrieval mechanism (in future)If the terminal capability is sent to the GSM, it is evaluated and dispatched spatial retrieval functions, then retrieved data is actively converted into various forms by the media conversion function. This mechanism corresponds with various level of portrayal model.
