![]() ![]() Each of these are labelled with two letters, which form the first part of every National Grid. I have so far downloaded an OS grid square layer and managed to isolate the individual grid squares from this layer that I need, creating 24 individual grid square layers. The whole country is divided into squares 100km x 100km. I've packaged this into a QGIS plugin (experimental) which should show up in the repository soonish. For my study I need to export Ordnance Survey 1km grid squares from my topographical data. Update - if I rename my map to map then this works: Map Centre is at In a layout you should be able to do something like: īut I can only get NULL as a response to any of the item_variables function calls - may be my map isn't called Map 1? Its a good excuse to get out more Its a free and open online community project for all. To get output like TF392033 or gridSquare(1, $geometry) to get TF3903. You can then use expressions like: gridSquare(.1, $geometry) Insert the following into a new Function in the Expression Function editor (see this class for more details of how to do this). Originally intended under the master plan to sit alongside the grid roads. Each of the original villages is the heart of its own grid-square. This was easy enough to do with the 1km MGRS grid shapefiles available from NGA.mil, but Im not sure how to do it in ArcMap itself. Most grid squares have a local centre, intended as a retail hub, and many have community facilities as well. They create up-to-date paper and digital maps for individuals and businesses to use. I want to be able to generate an MGRS grid of arbitrary resolution (say, 1km or 100m) and have each grid square individually labeled with its full MGRS coordinate. ![]() You need a custom function which I have translated from my Java translation of the OS Visual Basic to python. The Ordnance Survey (OS) is the mapping agency for Great Britain. ![]()
