I had to write code to convert MGRS to LL last year, however, I am unable to post the code. What I can post though are the two main resources I utilized while writing the code: US Military Grid Reference System description, published by NGA and the related Appendix and an Online MGRS to LL Converter to check your results as you are coding.
To convert back from mgrs to lat long use the following function. The input string must have metre (i.e. 5 digit) easing and northing resolution and have spaces as output by the above function.
What's the best way to convert MGRS using gdaltransform given that it doesn't have an EPSG code ...
2. What I gather from looking at the source code of the library is that MGRS is assumed to be the same as USNG but without spaces. When you call the LLtoMGRS function, behind the scenes all the library is doing is removing the spaces and calling the LLtoUSNG function. The library does have a USNGtoLL function, so I assume if you remove the ...
In the library's MGRS to LL function it states "create a Military Grid Reference System string. this is the same as a USNG string, but with no spaces. space delimiters are optional but allowed in USNG, but are not allowed in MGRS notation. but the numbers are the same." By that logic, presumably USNG to LL is MGRS to LL.
Isolating just the MGRS conversion code was not easy. GDAL: Was implemented in another programming language. IBM (via j-coordconvert.zip): Is complact, suits well for the UTM conversion, but the MGRS conversion is described to be errorneous. Alas. Is there a good (compact) Java source for converting between LatLon/wgs84 and MGRS?
oskarlin. 1,94112845. 3. If you have access to ArcGIS 10.x, there is a "Convert Coordinate Notation" tool that will do this. MGRS is a coded alphanumeric string based on UTM. – Neil Ayres. CommentedNov 12, 2014 at 15:25. This question appears to be looking for a mathematical formula that can convert without using an external tool.
return c + ad + ' ' + af + ah + ' ' + aa + ' ' + ab; }; To convert back from mgrs to lat long use the following function. The input string must have metre (i.e. 5 digit) easing and northing resolution and have spaces as output by the above function. function LatLongFromMGRSstring (a) {. var b = a.trim();
mgrs. The PInvoke Signature we used: [DllImport("mgrs.dll")] public static extern int Convert_Geodetic_To_MGRS(. double Latitude, double Longitude, int Precision, // 1 to 5, we used 4 (10 square meters) StringBuilder MGRS); which corresponds to this function in mgrs.h:
Below is the SQL for converting Military Grid Reference System (MGRS) to decimal Latitude and Longitude. It is very accurate, but not perfect. If you can make it work 100%, it is yours, but PLEASE
