Precisely Dan.
The issue here is to convert from “Israel_TM_Grid” to “Palestine_1923_Palestine_Grid”.
Unfortunately, none of the built-in algorithms available in ArcGIS can perform the job properly. We found out that the best way to do it is to move the rasters with -50000 in X and -500000 in Y. This way, the “Israel_TM_Grid” is converted precisely to “Palestine_1923_Palestine_Grid”.
Correct. Each raster has its aux:
<PAMDataset>
<SRS>PROJCS["Israel_TM_Grid",GEOGCS["GCS_Israel",DATUM["Israel",SPHEROID["GRS_1980",6378137.0,298.257222101]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]],PROJECTION["Transverse_Mercator"],PARAMETER["False_Easting",219529.584],PARAMETER["False_Northing",626907.39],PARAMETER["Central_Meridian",35.20451694444445],PARAMETER["Scale_Factor",1.0000067],PARAMETER["Latitude_Of_Origin",31.73439361111111],UNIT["Meter",1.0]]</SRS>
</PAMDataset>
What might be the best practice to move the raster with the value (-50000, -500000) other than applying the shift tool?
However, we are forced to convert them from ecw to jpg due to the fact that the ArcGIS Server doesn’t support ecw when it comes to publishing.
