First I would like to show you a short presentation about map services. Let me start with defining map service
A maps service also called (web map service, web map, web app...) is a tool for showing geographical information on the web. They are ussually interactive so you can view, analyze, extract or even analyze geodata. There are a lot of examples of web map services. For example... In these examples you can view a map and you can also view information about the features.
Why do we need a map service in HELCOM
This is extracted from our new data and maps web page. In HELCOM there is something called the Data and Information Strategy. It says that data and information activities should make possible to produce assesments, facilitate decission making AND MAKE ENVIRONMENTAL INFORMATION ACCESSIBLE. Environmental information has ussually a geographical component, it’s related to something happening SOMEWHERE. A map service is the best way to share geographical information.
Basicaly nothing was wrong with the previous map service. It worked and it worked fine for some years. BUT there were reasons why it was necessary to do the change: it’s based on an old technology which ESRI, our GIS provider, will eventually stop giving support. Also, the look and feel was ok for some years ago but not for today.
