You can get to the park by either the Red or Purple Line. The area is well-served by buses as well; please visit and let the Metro Trip Planner figure out your transit options. We hope to see you there!

Newly released maps show how Housing Discrimination Happened

This was certainly interesting to read about in the National Geographic – about redlining and the historical impact on minority communities.  I checked and you can download these as georeferenced images.

OSGeo Kids’ Map Gallery

Even as FOSS4G 2016 was ending in Bonn barely two weeks ago, organizers are busily preparing for FOSS4G 2017 in Boston next summer. Among many other things, a Kid’s Map Gallery is being planned, with prizes to be awarded at the closing session. Since many children will not be able to attend the conference, the awards ceremony will be on video.

“…End result? They find maps unbelievably amazing, do all their homework, go to bed on time and grow up to be brilliant open source geographers, and yes, they save the world. That is the plan…”

It was hard not to pass this along.

MaptimeLA Headed to Catalina Island – Should be fun!

maptime_la_catalina_islandI’m passing this along…

Our friends at MaptimeLA are looking for folks interested in heading to Catalina (9/30/16 to 10/2/16). From their invite:

Join us for a weekend of camping, mapping and collecting 360 photos on Santa Catalina Island. We want to improve the data on the island and give them “street view” via Mapillary. Never walked around and added points to OpenStreetMap before, but always wanted to? This is just for you.

More information can be found on their site:

Digital maps send all ‘bad’ requests to same coordinates; land of lousy data

If You Can’t Follow Directions, You’ll End Up on Null Island

Digital maps send all ‘bad’ requests to same coordinates; land of lousy data

Every day, countless people seeking digital directions on their computers and smartphones are diverted to an isolated spot on the Atlantic Ocean, 1,000 miles or so off the coast of Africa, where the Prime Meridian and the equator intersect. It’s called Null Island.

This lonely way station in the Gulf of Guinea is, according to its website, a thriving republic with a population of 4,000, a roaring economy, a tourism bureau, a unique native language and the world’s highest per capita use of Segway scooters. In the realm of digital cartography, it is one of the most-visited places in the world. The only problem for its millions of visitors is that there isn’t much to see.

Null Island doesn’t exist.
