College of the Canyons GIS

Need to fulfill a beginning GIS requirement?  Or just want to expand your knowledge and learn a new skill?  Then come join me at College of the Canyons and sign up for GIS 101, Introduction to Geographic Information Systems.  I promise you the class will be challenging and rewarding!  Also, your earned units are UC/CSU transferrable.

GIS 101 is filling up quickly, so register for the Spring semester as soon as possible.  The GIS class will meet at the Valencia campus every Tuesday from 6:30pm to 9:35pm, February 5 to May 28.  We start next week!

Feel free to contact me, Michael Carson (, if you have any questions.

Unintended Consequences with Data

Many of us that create GIS data and share with others have no idea of the unintended consequences that the data might produce.  Using data and ignoring the scale, resolution, accuracy, and where it came from might produce very wrong results.

ArcGIS Pro 2.3

ArcGIS Pro 2.3 just became available today.  Check out what’s new here.

Quite a few customer requests were added to this release.  To view what they are, ESRI has made a video of each request.

More info can be found here.  Release notes can be found here.

The system requirements for 2.3 can be found here.  ArcGIS Pro will not be supported on Windows 7 after January 2020.

And if you have been running ArcGIS Pro on a Mac using Parallels or VMware Fusion, at 2.3 you will not be able to do that anymore.  Instead you must use Boot Camp.  Read more about that here.
