Otherwise the projection information files in the current location will be Parameter is specified in addition to -c, then a new location will be created. In addition however, if the -c flag is specified, g.proj willĬreate new GRASS projection files (PROJ_INFO, PROJ_UNITS, WIND andĭEFAULT_WIND) based on the imported information. Not required that either the input or output be in GRASS Used to convert between representations of the information.
