GPS Data into ArcGIS Explorer Desktop – you don’t need the full ArcGIS suite to do it

Per ESRI’s tip at:

Census 2010 Data available through ESRI

If you have Business Analyst (online or desktop) or Community Analyst, ESRI has released Census 2010 data and geographies into those products!  Check out more details at:

“GIS on a sphere”

Thanks to Erik Gakstetter at Geospatial Solutions for bringing this to my attention.  Basically, it’s GIS displayed on a globe and it is big and it looks like it is leaps and bounds away from 3D on a screen or elsewhere.

Erik’s article is at:

Fourth Episode of Geospatial Revolution is out!

The series is great, and the fourth episode is no exception.  Check it out at:

GIS in Public Health Conference in Atlanta, GA on June 27-30, 2011

Please check out the details of this conference hosted by URISA if you are interested in the intersection of public health and GIS…

A KML view of the Bible

Thanks to the folks on the Maps-L listserv for bringing this site to my attention!  They’ve geocoded almost all of the Biblical places and even the bodies of water and made them available, for free, in KML format.

The twists and turns of geospatial data and privacy…

Many thanks to the folks at Flowing Data who help to graphically show some of the issues surrounding geospatial data and personal privacy.  See their post at:

Free Landsat Data from ESRI

This should be great for lots of us who are interested in the different Landsat layers such as natural color imagery, false color imagery, ag, vegetation and the like.  Thanks ESRI!  More details at:

Shameless self-promotion and a geodatabase online class

I’m an instructor in the UC San Diego Extension Certificate of Completion GIS program, and the third class in our series is starting up on 3/29/11 and it’s entirely online…so if you are looking for an introduction into geodatabases and if you have some (even limited) GIS experience but need some structure to get you to sit down and just do it, this might just the ticket!  The description of the course online is not quite what we do – rather it is more geodatabases and data sources.  The shameless self-promotion comes because I’m the instructor.  : )

SANDAG portal to 2010 San Diego Census data

Many thanks to John at SANDAG for making this data accessible!  Here’s the info on it per John:  Census data for San Diego are now available on the SANDAG website. Go to Census Data Online and look under “2010 Census Redistricting Data”. We have “filtered” the Census Bureau’s Redistricting Data from hundreds of fields to: total population; eight race categories; and three housing unit fields. The data are available as zipped Excel files. The census geographies are tracts and blocks. Also available are SANDAG Subregional Areas and Major Statistical Areas. This summer, the Census Bureau plans to release Demographic Data (age, sex, income). SANDAG will again “filter” the data and post selected information in our Profile Warehouse.

You can download matching shapefiles from the SANDAG GIS Downloads. Look for “2010 Census Geography” under Administrative Boundaries. The TIGER/Line shapefile data are projected from longitude-latitude to local California State Plane Coordinates. This is “raw” unadjusted TIGER shapefiles. We are in the process of adjusting some block boundaries to better fit local GIS layers (parcels, municipal boundaries, etc…). If you want or need the original TIGER shapefiles, please go to 2010 Census TIGER/Line Shapefiles Main.

Note: If you are using block-level data, please contact me. I am happy to share my experience concerning some of the strangeness (e.g. census voting districts).
