Maptive’s elevation tool displays measurements every 200’. The placement of these measurements will also vary between maps. You’ll find measurements displayed at certain levels. For example, when creating a map with Maptive the distance represented by the space between each contour line is 40’. Contour intervals may vary from map to map. The lines increase in elevation at equal intervals to allow you to determine the height at each level. They’re not straight, but rather they bend and weave depending on the shape of landmasses and changes in elevation. These lines are different from longitude and latitude. Contour lines indicate elevation on most maps, with each line representing a new level of elevation.
