Domain type: | any Value domain |
Output
MAPMIN returns: | a value |
Domain: | system domain Value |

Tips:
Usable in
Simple calculators, MapCalc, TabCalc
Examples
Pocket line calculator examples:
? MAPMIN(DEM) |
returns the minimum value of raster map DEM, e.g. 342 |
? MAPMIN(Rain.mpp) | returns the minimum value of point map Rain, e.g. 17 |
MapCalc example:
OutMap = MAPMIN(InMap)
InMap |
OutMap |
||||||||||||||||||
|
|
OutMap1 = InMap1 - MAPMIN(InMap1)
InMap1 |
OutMap1 |
||||||||||||||||||

TabCalc example:
OutCol = InCol + MAPMIN(InMap)
