GIS Day and PostGIS Day Coming Up

| |


Every year, GIS Day is celebrated on the Wednesday of Geography Awareness Week.  GIS Day was first celebrated in 1999. This year GIS Day will be celebrated on Wednesday, November 13, 2019 and will mark the 20th anniversary of this celebration.  GIS Day was initiated by Esri, a commercial GIS software company, who has a list of suggestions for celebrating this day.

The day afterGIS Day is PostGIS Day, which is more geared towards celebrating open source GIS apps and tools and is a clever take on the open source PostGIS.  You can follow along virtually and also find in-person events by tracking #PostGISday hashtags on social media platforms such as Twitter.

What are your geospatial plans for this week?   Here are some suggestions for celebrating both days this year.  If you have a suggestion to add to this list for GIS Day and PostGIS Day, email it to

Participate in #GISChat on Twitter

If you’re active on Twitter, each Wednesday at noon  (PT) you can participate in the global #GISChat where geospatial professionals discuss various GIS related topics.  Since GIS Day falls on a Wednesday each year, this makes the #GISChat event even more special.

Attend a Local GIS Day Event

Many educational institutions, government agencies, and geospatial firms hold GIS day events.  You can search for a local GIS Day event via the site.  Browse the map or use the search function to find events near you.

Attend GIS Day and PostGIS Day Online

If you aren’t able to make a local GIS day event, participate online by tracking events and photos happening on GIS Day via social media by following the hashtag #gisday on Twitter on Wednesday and #PostGISDay on Thursday.

If you are a participant on the 3D virtual reality game, Second Life, you can also experience the remnants of a virtual 2009 GIS Day held by the New Mexico State University’s GIS students and Geography professor, Michael DeMers.  NMSU’s College of Extended Learning and Information and Communications Technologies maintains a virtual environment on Second Life called Aggie Island.  The virtual GIS Day map gallery has been kept up as an example of how to use a medium such as Second Life to facilitate learning and collaboration.   The virtual GIS Day can be accessed from within Second Life via the landmark: AggieLand Public, NMSU Aggie Island (133, 76, 26).

Bake a Geospatial Themed Cake

One of the things I truly enjoy about GIS is that it can integrate with just about any subject matter.  I particularly love seeing artistic expression using geospatial technology and no GIS Day or PostGIS Day meeting is complete without some baked offerings.  The Collegiate Baker has instructions on how to bake a globe cake which uses a Bundt cake mold, printed out continents, and lots of blue and green frosting.

Send a geoGreeting

GeoGreeting works by spelling out words based on buildings and other features within Google Maps that look like letters (more fun with GIS and Geography).  Type in your message (up to 40 characters) and email the link to your recipient.  The web page spells out the words to your greeting letter by letter.

Here’s my GIS Day greeting:

Happy GIS Day
Happy GIS Day!
