CAUTIONS: DUE TO TECHNICAL LIMITATIONS...
POLYLINES ARE NOT SUPPORTED
- This tool only accepts POINT or POLYGON shape files.
DUPLICATION WOULD BE REMOVED
- Overlapping or adjacent objects (polygon, point) will be merged together automatically.
USE "SIMPLE" SHAPES PLEASE.
- No. of polygon vertices will be kept less than 500 per polygon. The same goes for merged polygons. This may collapse the accuracy and topology of your polygon data.
USE WGS84 Lat/Lon COORDINATES PLEASE. (NOT NAD27)
- Shape files are strongly recommended to have WGS84 coordinate system. Transformation to WGS84 will be attempted over non-WGS84 files basing on the given PRJ file or EPSG code, which may be inaccurate.
