Object Data Base: Spatial Data
The object oriented data base in WaterWare is implemented on industry standard relational data base engines
(RDBMS) such as ORACLE, MySQL, or PostgreSQL, with a high level of normalization.
The data base implementation supports basic numerical, symbolic, and hypermedia formats (text, imagery, video),
as well as an easy-to-use interactive menu driven interface,
and display, editors, and analysis tools. OBJECTS are dynamically instantiated when accessed,
so the system is always up-to-data, in real time.
SPATIAL data in raster, line or polygon formats cover DEM (30 m resolution), land use/cover
(USGS and various public domain sources, satellite imagery), soils (FAO), and basic geographical features
such as administrative boundaries, roads. The GIS tools support
interactive map generation,
a range of data import formats (e.g., ESRI) but also the choice between local,
UTM based raster and vector (combined) maps from a
map catalog and on-line Google map access.
See the introduction on the Embedded GIS manual pages .
Supporting tools cover a range of data import formats, and export formats such as various image formats,
but also NetCDF, or
Open GIS Web Map Services (WMS).
The Spatial data/GIS tools cover both spatial input data such as DEM, land use/land cover, vegetation, soils
and any Remote sensing (RS) data, but also serve as (interactively selected) background and orientation
for any georeferenced object display, including the grid-based rasters of hydro-meteorological data
computed by the
prognostic meteorological models.
