SPATIAL DATA MANAGEMENT BASED ON STANDARDS AND OPEN SOURCE SOFTWARE PRODUCTS
In order to create a geospatial data infrastructure (GDI), it is necessary to solve complex organizational, legal and technological issues. Currently, there is a number of multi-purpose commercial GIS, the most common of which are ArcGIS (www.arcgis.com), MapInfo (www.mapinfo.ru), GIS Panorama, etc. These GIS can store, manage, publish maps and map layers of indefinite scale and complexity. They have powerful functionality; through their use one can solve almost any application tasks. However, the high cost of the GIS and the high level of qualifications required in the projects push many users to consider other options. We offer the efficient technology for GDI management by building an integrated domain object model in the form of appropriate classifiers and by developing spatial data storage and geo-portal on their basis.
