Geoportals are databases for spatial data. The main purpose of geoportals is to provide a fast and handy search of necessary spatial data.

• aerial and space-borne images;
• digital elevation models;
• raster and vector layers;
• maps and plans.

Geoportal contains geospatial data about a city/town or about a region. There are also federal and global geoportals. For instance, "Google Earth" is the global geoportal.

All geoportals have user-friendly interface. A user can search an object by address, coordinates (lat/lon), keywords or any other attributes. As a result, a list of suitable objects appear. Another way to display results – visualization on a digital map. Geoportal's user will be able to see all metadata related to found objects.
