The Map Projection System used in Nepal is the MUTM (Modified Universal Transverse Mercator). Read more about Map Projection System in Nepal here.
In this exercise, I will be using ArcGIS. Other methods will be posted in the future.
- Load the data in MUTM. If you don’t have data yet, you can download from here.
- Go to the Search window and Search for Create Custom Geographic Transformation.
- In the next popup window, specify as follows:
Geographic Transformation Name: MUTM84_2_WGS
Input Geographic Coordinate System: Import from your data source.
Output Geographic Coordinate System: Go to Geographic -> World -> WGS 1984.
X-Axis Translation (meters): 282
Y-Axis Translation (meters): 726
Z-Axis Translation (meters): 254
Click OK.Note: Remember if you wanna do from WGS_2_MUTM84, then be sure to make these sign negative (-ve).
- Then, in the Search tab, search for Project (Data Management)
- In the Project window popup, specify as follows:
Input Dataset or Feature Class: Select the shapefile that you want to convert.
It should take the Input Coordinate System (optional) automatically.Output Dataset or Feature Class: Select the location and name accordinglyOutput Coordinate System: Go to Geographic -> World -> WGS 1984.Geographic Transformation (optional): Select the custom transformation that we just created. The name should appear as MUTM84_2_WGS if you followed along. Click OK. Your projected shapefile should be in the location that you specified.
