Hi guys and gals, We - a group of students working on an SL project - have a problem. Can we get the rez restricted and regular restricted/banned regions without entering them or crashing into them. We are trying to get the coordinates of all regions in a continent to create a path creation thingie and we need the coordinates for all regions. So far, we have a vehicle that we ride around and when we enter a new region, it sends the coordinates and the region's name to our database. We use these data to create paths. Basically, we need to somehow know which regions are closed before entering them. The reason we need to know which regions are rez restricted is that, we will not always stroll around and get data manually. Ideally, we would rez prims that report the traffic data and coordinates for all regions in a continent. But since we can't rez there, we can't... Any ideas, suggestions welcome. Thanks in advance, and here's our project blog: http://sltourismhub.wordpress.com/
