Superpowered attribute editing

Spatial is only part of geospatial data. Placemark handles the rest – attributes – with a particular pizazz. Table editing, editing JSON values, long text - we've got it.

Works with your data

Have a CSV file with coordinates? How about a GeoJSON file? Or some KML from Google Earth? Maybe you're drawing data from scratch. It'll all work great with Placemark.

Build maps together

Placemark is perfect for your classroom, newsroom, or situation room. It works if you and a friend have an idea to find all the best coffee joints, or share a new mountain biking trail you recorded with GPS. Collaborate in real-time.
