WEB-based Geoinformation Data Warehouse Prototype
WEB-based Geoinformation Data Warehouse Prototype (GIS DW Prototype)
is a database-centric WEB-GIS (or GIS-Internet) decision focused directly on end-users, and based on using of: reliable and productive
ORDBMS Oracle 10g; universal and effective J2EE platform; simple and flexible
XML-based technologies.
Fragments of GIS DW Prototype user interfaces
Demos of GIS DW Prototype may be obtained from Downloads
section.
GIS DW Prototype basic functionalities:
1. Use of a standard WEB-browser for user applications.
2. Accumulation, storage and search of the mixed information - spatial and
nonspatial data (SAND) in a uniform database (recommended and current ORDBMS:
Oracle 10g, but it is possible adopt GIS DW Prototype for use of noncommercial
RDBMS, for example MySQL).
3. High-quality multi-color 2D vector visualization of SAND with
capabilities of zoom and pan and management of SAND layers on client and server
levels.
4. Realization of basic operations of the spatial analysis (calculation of
the area, centroid, perimeter, length; association, subtraction, interaction;
topological operations: "within a distance"; "overlap", ", "touched" etc.);
Spatial Clustering.
5. Dynamic search of the shortest routes ("routing") on the basis
of network model.
6. Real Time (more exact quasi-real time) SAND Subsystem (interval of SAND
auto updating: from 5sec).
GIS DW Prototype includes more than 40 thematic layers of SAND - the information about USA Counties,
obtained from: USDA Forest Service; National Weather Service; U.S. Geological Survey; USDOT/BTS; Environmental Systems Research Institute (ESRI) and other (see About Project section).
