DMAP: UTM Grid Zones of the World There are 60 longitudinal projection zones numbered 1 to 60 starting at 180°W. All you need to do is add the UTM parameter to your link and launch the link. The important feature of the Universal Transverse Mercator Projection is that the zones are standard and readily identifiable, so that an area may easily be designated as lying within a specific zone. In the far north, where zones are narrow, medium- and small-scale maps may show parts of more than one zone. By convention, the edges of most maps fall along parallels and meridians. Right-click the ne10madmin0countries layer and select Save As. ![]() Utm projection series#Use the Select features by area or single click tool and click on United States feature to select it. Please note that this is not a new revised projection, but a series of maps using the same projection (Transverse Mercator). In Canada this is done to produce the 1:250 000 and 1:50 000 scale maps, which are the two scales of the National Topographic System. Rather than re-projecting the entire layer, we can also re-project some features from the layer. UTM projected coordinate systems are conformal and their distortion of other map properties is minimal. Because this is a narrow piece of the earthwithin 6 of longitudeyou can use a UTM zone. The white rectangle represents the area you want to map. This GaussKrüger system is similar to the universal transverse Mercator system, but the central meridians of the GaussKrüger zones are only 3° apart, as opposed to 6° in UTM. These basic sheets are divided further into sections and each section is published as a map of a larger scale. In addition, this projection distorts area and distances dramatically in higher latitudes. Once the zone has been flattened onto a level surface it can be divided into a basic set of map sheets of a convenient size. ![]()
