A Universal Transverse Mercator zone embraces a much larger portion of the earth than does a state plane coordinate zone. It is four times less precise than typical State Plane Coordinate systems with a scale factor that reaches 0.9996. We do some trickery by converting the UTM domain to km so that we canĪdd custom annotations to the map. UTM with the Universal Polar Stereographic system covers the world in one consistent system. UTM is a conformal projection system because the scale factor is applied in all directions. The UTM projection when overlaying the coastline and light blue ocean. The distortion due to the scale factor is less than 0.1. Then, given we are in UTM zone 5Q, we use the UTM domain and We first lay down the UTM grid using the linear Meters) of elevations near Kilauea volcano on the Big Island of HawaiiĪnd overlay geographical information (with longitude, latitudeĬoordinates). ![]() Our script illustrates how we would plot a UTM grid (with coordinates in Use the same scale with both the linear and UTM projection. Meters but supply the actual UTM projection parameters. On the same map you simply have to specify the region using the UTM The only sensible way to plot such data is with a linear However, that data have already been projected and is now in linear GMT rookies make is to specify the UTM projection with their UTM data. Geographic data, such as coastlines or data points. Next, we present a similar case: We wish to plot a data set given in UTMĬoordinates (meter) and want it to be properly registered with overlying (28) Mixing UTM and geographic data sets ¶ ![]()
