Usefulness of GIS as a robust tool for decision planning depends entirely on the quality and authenticity of the database (spatial and aspatial) it is built upon. These databases can be of various types like the paper maps, softcopy (Pdf, Jpegs etc) maps, AutoCAD drawing, field reports, tabular charts etc. However, to produce a error less and truly realistic database, survey plays an instrumental role either in creating new maps of an entirely uncharted area or in modifying and geocoding exiting maps with real world scenario or collecting Ground Control Points for orthorectification of satellite image. A currently surveyed dataset can be relied upon to make informed decision about development planning of an area.
