Exports a selected Area of tiles into a .MAP file which can be imported into Warlanders DeedPlanner
----THIS IS A SERVER MOD!---------
1. Create a construction Marker
2. Activate the construction Marker
3. Right click the construction Marker and select a survey area size that you want to export. The numbers are the Radius of tiles around the Player. so 5 would be 11x11
4. Right click the construction Marker again and hit Survey Area
5. Hit the export button to export a .map file to a location of your choice
Sometimes it takes a while for the save window to open if you hit the button more than once multiple save windows are going to open just close them and you are good.
