Terrafirma is mapping tool for Terraria.
It gives block information
in the statusbar as you hover, lets you zoom and pan around your map, and
can save your map out as a png.
If "Use Textures" is grayed out, it's because the program can't find your Terraria directory. Go to Help » Settings and adjust your paths, then restart
