How ArcMap Aligns Your Data

[sharebox sharetext=”Share This Page”] [/sharebox]

For today’s video blog topic, it’s back to the basics.  Understanding coordinate systems and how ArcMap handles them is fundamental to a proper understanding of GIS.  This is a topic a struggled with — a lot ! — when I was first learning GIS on my own.

In this video, I will show you how to investigate the coordinate system information of your data and how ArcMap handles data with different geographic and/or projected coordinate systems.  There’s even a part that shows what happens when a shapefile is missing its projection file.


Still confused?  Why not take one of our online training courses?  Working with Coordinate Systems in GIS & GPS covers this topic in great detail.  You can learn more about it by visiting or clicking on this link. The course is part of our GIS Bundle.
