Example of calculating with minimum and maximum values of coordinates
It might occur that you have a point data set from which only a part of all points lay inside a certain area. You can select only these points to show or to use them for further calculation. In this example, it will be tested whether the points of a point map lay within the area of an existing land use map. The coordinates from the lower left corner of the Landuse map are: (795480, 8071880) and the coordinates from the upper right corner: (808220, 8090520).
Select = INRANGE(CRDX(Coordinate), MINCRDX(Landuse), MAXCRDX(Landuse)) AND INRANGE(CRDY(Coordinate), MINCRDY(Landuse), MAXCRDY(Landuse))

Points 3, 4 and 7 do not lie inside the boundaries of the land use map. The X-coordinate of point number 3 is lower than the minimum X-coordinate of the Landuse map while point numbers 4 and 7 have Y-coordinates which are larger than the maximum Y-coordinate in the Landuse map.
