Research on design and development of software and technological support for geo-portal of ICM SB RAS are discussed. Its main components and implementation details are presented. A number of problems are discussed in details, such as web-based metadata catalog, the logic of building applications based on web services geoportal. A list of implemented information systems, based on discussed technologies is presented. The authors were directly involved in the develop-ment and implementation of geoportal based projects. In developing the software many different software libraries and components were used. Web mapping user interface was created using a number of open source libraries. To create a server-side web application authors used GIS platforms MapGuide Open Source and Min-nesota Mapserver. GeoWebCache was another essential component of distributed web mapping ap-plications. By analyzing and summarizing the experience gained creating information systems, it should be noted that the use of geoportal-based solutions in this area, can dramatically improve the efficiency of software development and problems solving.
