But it is a tedious process, so you might be better off just using lat/lon It is possible to add a UTM grid to a map that is only

Many other map makers only provide lat/lon references. USGS puts both lat/lon and UTM coordinates on all of their large scale That have been supplied by the map maker. On larger scale maps the choice of coordinate system is often determined by the coordinate references Of longitude appear to be parallel, such as a Mercator projection. Small scale UTM gridded maps need to use a projection where lines That will result in UTM grids that are not square. Small scale maps are often projected using a map projection Less, you will probably want to use lat/lon coordinates. If you are working with maps that cover more than 6 degrees of longitude or are 1:1,000,000 scale or Use a system that works well with your maps You will find that most aviation and maritime users are already using lat/lon coordinates. Something better and you're willing to be the force behind the change. Unless of course you're convinced they should all change to Same coordinate system and notations that they use. If you are working with other folks and passing map coordinates around, then you will want to use the Use the same system that your peers are using Lat/Lon – Using Latitude Longitude Coordinates.kUTM - UTM with kilometer based measurements.For specific information on the two coordinate systems, check out the tutorial pages. When it comes to selecting tools for plotting and measuring coordinates,Īll of our tools that work with the UTM system also work with the other UTM based systems USNG, MGRS, and kUTM. To help you make the choice between using UTM based coordinates or lat/lon coordinates. But, as muchĪs I like using UTM, there are some circumstances where lat/lon is a better choice.

Many land based users will find them to be easy to use and well suited to their needs. I would urge you to consider coordinate formats based on the Universal Transverse Mercator map projection and coordinate system.

Never consider that there may be other coordinate system that would better meet their needs. Most GPS receivers come out of the box set to use latitude/longitude coordinates.
