Problem in conversion raster to shapefile

Mohd_NurhafiziSaidin — Tue, 25 Apr 2017 08:17:37 GMT

Hello everybody,

I'm doing the conversion from Raster with tiff format (with GDM_2000_MRSO Spatial reference) to polygon shapefile. I want to set the new shapefile with WGS84 for spatial reference. The problem is, the new shapefile with WGS84 not match with imagery basemap (esri basemap) or others basemap with spatial reference wgs84.

can somebody tell me the best idea to convert tiff to shapefile? with gdm 2000 mrso to wgs84?

is it good to do conversion in arcgis with different spatial reference?

Please help me..

Thank you.

Hi,

when you convert a raster into a polygon, if the Raster has a Coordinate System, the resultant shapefile will retain that CSR.

Make the conversion with "Raster To Polygon"

Once you have the shapefile, in ArcMap use the tool "Project" to transform your data from the GDM2000 to WGS84.

hope it helps.

We don't have any transformations between GDM2000 and WGS84. There are no publicly available transformations. You need to talk to JUPEM, if you need that level of accuracy.
