If you don't have ArcView 3.2, or are frustrated from the speed of AV3.2's Projection Utility Wizard you might need an extension to convert your data between your local datum and WGS 84
Datum Conversion Sample extension (provided by ESRI) allows conversion of the shapefiles between various datums. It uses Standard Molodensky Datum Transformation as defined in DMA TR 8350.2. The extension works fine to convert a Local Datum to WGS 84, however the conversion from WGS 84 to a Local Datum gives incorrect results (to try it convert a shape file in aLocalDatum To WGS 84 and then back To aLocalDatum using the ESRI's extension ).
NEW:
Have you had the frustrating messages?
ERROR: "Unable to read datum.par"
ERROR: "Unable to load datum parameters"
Have you wondered what to delete from the provided script or in which directory to place the parameters file ?
This update will spare you all these troubles. Just load and RUN.
The extension provided here uses the ESRI's code with some modifications:
Creates new shapefile
Produces CORRECT results when converting from WGS 84 to a Local Datum
All the Datum Parameters are embedded in the extension |
