About Us

This Gaslamp Map has been created using esri’s ArcGIS mapping software. 

It has been updated every year since 2004 by the founders of BallparkGIS, Martha S. Rodgers, MBA, GISP, and her husband Jim Rodgers, President of Research and Ground Truthing.  Jim and Martha Rodgers have been in the GIS/mapping business for over 2 decades.  They enjoyed living in downtown San Diego for several years.

Ms. Rodgers is also a Real Estate advisor working with buyers, sellers and investors in the San Diego area.  If you have any questions about San Diego real estate please contact Martha, she’d love to help you out!  You can access more information at

This map was first created specifically for the annual
ESRI User’s Conference held at the San Diego Convention Center.  However, now both visitors and locals are downloading the map every day!
