Traditionally, scale bars are based on the origin point of the map’s coordinate reference system (CRS), commonly the intersection of the equator and Prime Meridian. Many users don’t realise that the scale bar may be inaccurate due to the distortions that occur with any map projection. In ArcGIS Pro, this inaccuracy can be reduced with the “Compute at center” property, though not entirely corrected for every map Not all…
Read detailsOn our dynamic Earth, continents don’t sit still. They slowly move around the planet, stretching oceans and lifting mountain ranges. Sure, it’s not like you risk being overtaken by Africa on your commute. Tectonic movements average a couple of centimetres per year – about the same speed as the growth of your fingernails.
