I'm trying to compile a list of MGRS 100km square identifiers for every such square (eg 4QFJ for Honolulu Hawaii); excluding the poles (85 to -85 latitudes). If possible it'd also be great to know which of these 100km squares intersect land.

Is there any way to compute this or is there a recommended data set to look at?

  • What GIS software are you using to try and do this?

  • I'm not using any gis software but I would be open to doing so. I was really hoping that there would just be a list of these values somewhere though @PolyGeo

  • If you are after data, rather than help with using GIS software, then the Open Data Stack Exchange may be worth looking at. If you decide to ask there then be sure to check their Help to make sure that what you are asking is on-topic first.

    Calculating MGRS squares from scratch is NOT something you want to do without GIS software. I had the Esri Projection Engine to help, and it still look a great deal of effort to build what I needed. Part of the issue is that the tiles at the edges of UTM zones overlap.

  • Exactly @PolyGeo
