Come join us for the second #editathon event of 2013, a weekend of mapping on April 20-21. All over the United States, we will be improving OpenStreetMap starting at 12 noon Eastern going until 6PM Pacific.
In Portland, we'll meet at noon on April 20th. At 1:00pm, we'll have a brief presentation introducing OpenStreetMap and the tools for editing it.
Then we'll start editing, either on your own or on one of our to-be-determined targets.
