Global Positioning System Reference
In-Depth Information
Users interested in analyzing this data must access separate systems, which
also limits the number of variables that can be requested. Furthermore,
each aggregation or different combinations of variables requires another
query to be issued.
On the other hand, CCP counts on publicly available spatial data that
refers to a wide variety of topics, e.g., administrative distribution, health
or economic regions, localization of beaches, bank agencies, schools,
clinics, crop distribution, risk zones, national park distribution, among
others. This spatial data is represented as a shape fi le (ESRI 1998) that uses
hybrid architecture where spatial and related conventional data is stored
separately. An example of a shape fi le for Costa Rican districts is given in
Fig. 2. However, spatial data is not delivered to the CCP users due to the
lack of the system that instead of displaying conventional data attached to
the shape fi le allows the integration with other data related to the topics
of interest of CCP users.
