iMap 4.0Effective management of spatial information

About iMAP

iMap is an application developed for ArcIMS technology few years ago (2005). With the development of spatial data servers and the introduction of ArcGIS we switched for AGS technology.

The first release of MVS application (thin client) for AGS was very unstable, “heavy”, most of the operations were conducted by server, making it impossible to support large number of users (i.e. one user session was consuming around 300-500MB of RAM).

After almost a year of trials and improvements we have decided to drop MVS and start working on our own thin client, that’s how iMap 3.0 andsubseqently 4.0 started. We chose to use Java and focus on “no session” approach. After few months we had a product which was fast, reliable and what is most important - open for implementing new functionality, being able to catch up with market demands.

iMap 4.0 is a network service providing a view service in scope of INSPIRE Directive regulations.

iMap 4.0 allows to integrate numerous map services and provides dedicated tools in scope of browsing objects localization, selection, reports and analysis.

iMap 4.0 enables authorized access to data services providing application functionality both for Internet and Intranet users.

iMap 4.0 provides functionality to edit spatial data by means of standard Internet browser.

iMap 4.0 does not require installing any additional plug-ins in web browser.
