Name | Type | Description |
---|---|---|
_ptg | ITGIS_Point | reference point |
_prec | double Double | precision /not longer distance than/; point inside polygon is always not greater than _prec; if _prec less then 0 then being outside/inside polygon means the same; |
_part | int Integer | part number to which the distance will be computed |
_proj | ITGIS_Point | point projected to a nearest element of the shape |
Type | Description |
---|---|
double Double | Distance in map units. |
