GEOREFERENCED INFORMATION PROCESSING SYSTEM - SPRING
1. Purpose and objectives
To be a free-distribution geoprocessing tool for the development of Geographical Information Systems (GIS).
SPRING (from its name in Portuguese: Sistema para Processamiento de Informações Georeferenciadas) is a 2nd generation geographical data base for UNIX and Windows, with the following characteristics:
* Operates as a seamless geographical data base with a large volume of
* Supports both raster and vector data and integrates remote sensing
* Provides an easy-to-use and powerful environment, with a combination
* Works with the same functionality on desktop PCs and on
* Contains innovative algorithms for spatial indexing, image
* Data base is unique. The data structure is the same on desktop PCs
Point data, such as hydrological and meteorological data from georeferenced stations, and spatial data derived from satellite images, aerial photographs or radar images.
Thematic maps, such as isolines maps, spatialization of point data, etc.
5. Operational requirements and restrictions
For its operation, SPRING needs a system with minimum 32 Mb of main
memory. The minimal installation of SPRING requires 50 Mb disk space. It is
recommended to reserve at least 500 Mb for the data banks to be created by
the user. Peripherals such as digitizer boards, HPGL compatible plotters
6. Form of presentation
SPRING 3.0 is available via CD-ROM or from the Internet. To install
it, follow the instructions on the Installation Manual or on the web page.
7. Operational experience
SPRING has been used extensively in various applications in Brazil and other countries. Examples can be found in the software tutorial. SPRING 3.0 was tested on the following setups:
* SUN SPARC workstations using Solaris 2.4 or higher;
* IBM RISC/6000 workstations using AIX 3.2.5;
* Silicon Graphics workstations, series IRIS 4D, using IRIX 4.0;
* Hewlett-Packard workstations, series HP-700, using HP-UX 9.0;
* Dec Alpha workstations using OSF/1 version 3.2;
* IBM PC compatible microcomputers.
8. Originator and technical support
