[udig-devel] How to implement custom DataStore?

[Filip Krikava <fikovniky@xxxxxxxxx>]

Hello,

For couple of months I was working on an eclipse based application for  
traffic data analyses and now it's time to add some GIS support and I  
decided to use udig, which looks really nice.

What I need to do, is to display a map which consists of number of  
road stretches. I have is a file-based database that have an interface  
which provides a method that for given geographic coordinates and  
given list of road classes returns a list of all road stretches with  
attributes like name, geometry, maximum speed, etc. The data set is  
rather huge about 2GB, in order to keep good responsive UI it needs to  
limit the number of stretches to minimum - filtering based on zoom  
level (on the country level it only makes sense to show motor-ways for  
example).

I'm very new to both geotools and udig and I was wondering what is the  
best way to implement it.

Thanks a lot for help
Filip
