In Reefmaster, the vector maps created can be manipulated for draw order (level), which is intuitive. What I am not understanding is where the draw order data is stored in the output datafiles (.shp, .dbf, .shx, .prj). I don't see anything in the relevant .dbf file, which is where I expected to find it. I'm trying to convert a large shoreline/lake polygon/island (essentially this is a basemap) dataset currently stored as an .mp file to .at5. I can export it using Trevor's tutorial (thanks again for all that you've done here!), but I want to give it a low draw order so that Reefmaster output data will show on top of it in areas where I have bathy data. Surely this can be done?
