Of course, purists will say that the unknown is what makes them fun, but with some Terraria map viewers, you can also edit your map to stop corruption from destroying your work of art.

MoreTerra is a simple Terraria map viewer which will load the world file and output a picture with the fog-of-war removed and all points of interest marked on the map.

While the output picture is detailed, you cannot zoom in to see all the details from each biome. This tool is designed to give you an overview of the map and to do some analysis on the contents.

Form the World Information tab, you can filter chests and see both their location and the contents. Additionally, you can set custom markers for people, containers or specific minerals. This will allow you to hunt down elusive materials needed for crafting.
