Geoportals are databases for spatial data. The main purpose of geoportals is to provide a fast and handy search of necessary spatial data.
Stages of creation:
Geoportals can store the following types of information:
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.
Advantages:
- thematic vocabulary and portal's structure development;
- metadata profiles' projecting;
- creation of the storage, search tool and visualization.
Geoportals can store the following types of information:
- aerial and space-borne images;
- digital elevation models;
- raster and vector layers;
- maps and plans.

Advantages:
- high resolution of images;
- reliable and relevant information;
- an opportunity to study and analyze hard-to-reach locations;
- any scale available.
