Converting MUTM Everest Coordinate 1830 to WGS 84 using ArcGIS: Projection and Transformation

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.

  1. Load the data in MUTM. If you don’t have data yet, you can download from here.
  2. Go to the Search window and Search for Create Custom Geographic Transformation.
  3. In the next popup window, specify as follows:
    Geographic Transformation Name: MUTM84_2_WGS
    Input Geographic Coordinate System: Import from your data source.lekmmdx
    Output Geographic Coordinate System: Go to Geographic -> World -> WGS 1984.
    Method: MOLODENSKY
    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).3pegkup
  4. Then, in the Search tab, search for Project (Data Management)
  5. 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.

Batch zipping your shapefiles with Python

    where do you get parameters

    I got slight displacement in the output layer with this method but without applying any custom geographic transformations I got no displacement at all in the output layer. I am using ArcGIS desktop ver 10.8.
    The output was completed with a note saying there was a datum conflict between input and output but it seems everything is ok.

      Good to know. Thanks! I can try it later and update the post.

  3. I would like to ask how do you got this parameter. Can you site the source? Also, the Survey Department for Nepal is responsible to provide the official transformation parameter, which don’t match the parameters you used. So, please contact SD for parameters.

      This was given by a friend at SD. Since, you are affiliated with the SD, could you help provide the source and parameters here?
