I have some coordinates in datum REGCAN95, and I want to know how to convert them to something usable in OpenStreetMap. I have found that REGCAN95 uses the EPSG codes as follows:
For example I have the coordinate 28BR205306 or 28BR067530, which I want to find in OpenStreetMap or other webmaps. How can I convert them? PS: I have also asked this on GIS.stackexchange.com and got some comments with hints, but no answer. I answered it myself, as I have found a solution via the Wikipedia page abouth the MGRS reference system. |

Conversion to & from various co-ordinate systems is usually done using the Proj4 library. This projection occurs in proj4 with the following parameters: "+proj=utm +zone=27 +ellps=GRS80 +towgs84=0,0,0,0,0,0,0 +units=m +no_defs", which appears to be identical to EPSG:3187 shown here on Spatial Reference. This site allows on-line conversions between many reference systems. Otherwise you will have to make use of tools provided by OSGeo. This question has been asked & answered on GIS Stack Exchange also. The OP did not provide this information. Thank you for your answer. I like this proj4 tool, because you can convert many coordinates per script at once. Well, theoretically. I tried it with your command:

I have searched on spatialreference.org and there seems no data about EPSG:4083.

To use cs2cs/proj4 to convert the locations, you would first need to translate the MGRS representation to a UTM representation. proj4 doesn't understand the MGRS representation.

@erik Re: EPSG:4082. Yes I'd have told you that but thought I was wasting my time with my answer. However I thought what I had written might be of some use to someone else.

@maxerickson Would you mind telling me how to do so? I mean, how to translate MGRS to UTM with cs2cs? Or is that impossible? Maybe another commandline tool?

There is no support for MGRS in cs2cs so you would need to use another tool.

Please dont duplicate questions here & on GIS Stack Exchange. Or if you do, say so; and certainly take the trouble to update the query when it's already answered. It's very frustrating to start writing an answer & find the query has already been answered. I like to help, NOT HAVE MY TIME WASTED.
