As the Internet develops into a more powerful cyberinfrastructure (the Grid), Geological Survey knowledge will enter a framework where users assess its value by its relevance and evaluated reliability rather than its source, and artificial boundaries of place and discipline lose significance. Within Geological Surveys, much effort has been devoted to the development of the geological map throug...

Geological engineers have mostly been involved in geotechnical problems since the beginning of 19 century. Engineering geological maps and field data are needed to solve these problems. The amount of data for these maps is extremely large, so putting all the map elements on the map sheet causes difficulties while solving problems. The magic words, Geographic Information System (GIS) is a tool f...
