Join Adam Wilbert for an in-depth discussion in this video Understanding projection and coordinate systems, part of Up and Running with ArcGIS.
…Whenever you make a map, you're abstracting…information about the real world and placing it…on to a flat plane such as a computer screen or a piece of paper.…Since the planet earth isn't flat, some distortions of…the data will inevitably occur during the transformation process.…These show up as distortions of area, shape, direction, distance, and scale.…Various map projections try to minimize the distortions,…but no projection can eliminate all distortions at once.…Coordinate systems, on the other hand, are how we locate a point on the Earth.…Typically, we think of the latitude and longitude values of…a GPS receiver as being the coordinates of a place.…
But it's only been in the last few years…that GPS coordinates have been so easy to obtain.…There are many other ways to locate a point.…The state plane coordinate system, for…example, was designed to make surveying easier.…Measuring the number of feet north and east…of a standard location that was used state wide.…An in-depth review of the math behind these complex…
