Name | Type | Description |
---|---|---|
_ptg | ITGIS_Point | reference point /searching point/ |
_prec | double Double | precision /not a longer distance than/; for points inside the polygon (if _prec >= 0) the distance will be multiply by 0.95 (to prefer points inside the polygon) but will not be bigger then _prec; for point distance will be multiplied by 0.9 to prefer points over lines and polygons; precision is express in map units |
