And while projected coordinates systems are typically preferred to a geographic system, you often need to know their zone number to load them quickly in various software applications you also need to know the zone number if you wish to reproject a spatial file in an alternate projection into UTM. There are some high quality options out there but it seems that most use Google Earth for their base maps.The vast majority of the order polygons we are sent and then the data we deliver here at Apollo Mapping is in a projected coordinate system such as Universal Transverse Mercator (UTM). Google Maps and Apple Maps are okay but I need access to high quality aerial imagery for professional uses. I really wish there was a better option. I've tried to use google earth for +/- 10 years and it has never worked properly.

Many spatial data users choose UTM (the coordinate system) WGS84 (the datum) as their projection of choose as it is generally accepted as the most accurate way to represent spatial data. A projected coordinate system is a mathematical function that lets us display data from a curved globe on a flat computer monitor or piece of paper and then the datum is the generalized shape of the planet used in this mathematical transformation. In order to display spatial information in its correct location on the planet, this data must be assigned a projection which is comprised of a coordinate system and datum.

If the data is above the Equator, then it would be in zone 24 North and if below the Equator, it would be in zone 24 South. Finally round-up to the next highest whole number.So for example, the UTM zone number for 39В° W would be found through these steps:So 39В° W is in UTM zone number 24. Most often, people will choose a coordinate in the north-west corner of their data, and assign it this zone number even if the data straddles two zones. Take your longitude coordinate in decimal degrees and add 180. Here is a re-hatch of the technique described in my two-part series above: Option 1 вЂ“ The Mathematic ApproachIf you know the left (or west) most longitude of the dataset in question, then one approach to determining the correct zone number is using good old mathematics.

Then click on the Identify button to see what zone number your spatial dataset falls inside of. Option 3 вЂ“ Check the Zone Number in ArcGISIf you have access to a copy of ArcGIS (or a similar GIS software application) and a shapefile of UTM zones, you can simply load the UTM zone grid file and the spatial dataset in the same session. The zone number would look something like this in a text editor:So we are in zone 28 North in this example. PRJ file with it, you can simply open the PRJ file in a text editor like Notepad or Wordpad to find the zone number.

Be sure your units are set to Universal Transverse Mercator in Google Earth вЂ“ if they are, you will find the zone number at the bottom center of your screen when you zoom in on the KMZ/KML.In the video that accompanies this article, I will walk you through the steps to complete Options 2, 3 and 4 above. Option 4 вЂ“ Check the Zone Number in Google EarthIf your dataset is a KMZ/KML file or you can convert it to a KMZ/KML (for instance by using Image Hunter for the conversion), then you can load it in Google Earth to find the zone number. This is probably the best way to determine your zone number if the dataset is a raster file.
