Good first try, some serious issues

Good ability to measure distance and area.
Map centers OK, but annoying that pins drop in top left corner where cross hairs are (iPad1 with updated iOS).
GPS coordinates way off. Try todays earthquake at 17.431°N, 93.978°W , it points just outside of Veracruz, instead of near Las Choapas, hundreds of miles away.
If you fix these, then four stars.
To get five stars, you have to be able to combine on road routes with off-road portions!
