PROJ4 Visualiser is a practical tool that allows you to pinpoint coordinates and view map data anywhere in the world. The application allows you to locate certain geographical coordinates and to view detailed maps from online sources.

You can choose the type of information you want to view and the program will retrieve it from BMNG, LANDSAT, NaturalEarth imagery or Google. The data can be exported to WKT files in order to be used with other applications.
