Join Adam Wilbert for an in-depth discussion in this video Understanding projection and coordinate systems, part of ArcGIS Essential Training.
- Whenever you make a map,…you're abstracting information about the real world,…and placing it onto a flat plane,…such as a computer screen or a piece of paper.…Since Planet Earth isn't flat,…some distortions in the data will inevitably occur…during that transformation process.…These show up as distortions of area,…shape, direction, distance, and scale.…Various map projections try and minimize the distortions,…but no projection can eliminate all distortions all 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 from 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 is used for each state in the United States.…Let's go ahead and explore some of these concepts…
