Paradise Project
Goal:
The stated goal of this project is to "apply object-oriented and parallel database technology to the task of implementing a parallel GIS system capable of managing extremely large (multi-terabyte) data sets such as those that will be produced by the upcoming NASA EOSDIS project. [1]"
Overview:
Paradise is an extended object-relational database system: not only does it support the standard data types, but it also has "built-in support" for vector and raster data (i.e., raster, polygon, polyline, point, circle data types) [3].
Features:
- Employs parallelism
- All data types, both standard and GIS, are implemented as ADTs (in C++)
- GIS data types implemented:
- Vector data: Paradise includes point, polygon, polyline, swiss-cheese polygon, and circle ADTs
- Raster data: Paradise supports 8-bit, 16-bit and 24-bit pixel sizes for raster data
Concerns:
Evaluation:
Notes:
- Supports clipping of raster files to a polygon (vector file)
