Abstract

The paper shows the possibility of creating digital spatial data using the software product with open source Quantum GIS and "conditionally free" space imagesof Landsat. Outlined the course of work with QGIS to create simple digital spatial data. Describes step-by-step extraction and how to order Landsat images. The technique of creating digital spatial data with attributive information as the form of a point, line and polygons is presented. The notion of spatial data as a state resource is given. The reasons for the formation of geospatial data in the form of spatial data infrastructure (local, agrarian, national) are justified. The presented work can serve as a starting point for mass creation of digital spatial data with application of actual raster data.
