The Web GIS is one of the Geoinformation Technology

fields.

The basic tasks of Web GIS are:

• Visualization - spatial representation of the

existing information

•Simplification of work with the spatial information in a

web;

•Managements and publication of spatial data, search and

other services based on a site of objects (LBS - location

based services)

Conclusion

Creating of centralized WebGIS database will lead to success in every field of work related to spatial analysis. After completing of the module WebGIS you can build your own map in Internet with different attribute data. It means that you will be architecture but not client (user) of this product.

The Laboratory exercise and assignment you can find in the folder \\gisnet\Pi_webGIS\
