• Hello 2019! Let’s talk PostGIS and Spatial DBs!

    Happy New Year! We hope one of your resolutions is to attend GeoDC every single month. :) 2019 will be momentous for GeoDC. In April, we have the American Association of Geographers (AAG) conference in town, and July is our 10th birthday. Are you excited? We are! This month is all about spatial databases, especially Postgres. We have a number of fantastic talks for you: Paul Ramsey will present on PostGIS. PostGIS is a widely used spatial extension to the PostgreSQL database that adds types, functions and indexes suitable for carrying out a wide array of GIS operations right within the database environment. Paul will review the many features of PostGIS, some interesting GIS problems that can be solved with them, and provide a peak into changes planned for the 3.0 version next year. Dan Noble will present on how Geofable, a tool for building map-based infographics, uses PostGIS under the hood. Topics will include spatial indexes, PostGIS and Python with Geoalchemy2, GeoJSON generation, vector tile generation, and more. Nick Ingalls, Geocoding Engineer at Mapbox and Co-Founder of OpenAddresses, will present on Hecate, a modern Geospatial Feature Storage API.

  • Street-Level Imagery

    Local 16

    We have another exciting round of lightning talks for you this month! However, instead of looking down from above, we will be looking around our neighborhoods. Street-level imagery is possible thanks to both companies and volunteers collecting millions of images of their surroundings. Besides being fun to view (how many hours have you spent using Google Street View?), there are a multitude of practical applications using this form of location intelligence: Max Grossman will give a quick intro to street level imagery. Dan Joseph from the American Red Cross will talk about how he uses street-level imagery for disaster response and preparedness. Holly Krambeck from the World Bank will discuss using street-level imagery to plan for road investment in Laos. Agenda: - 7:00: networking - 7:30: lightning talks - 8:00-???: more networking! On the first Wednesday of the month, we gather to socialize, network, and hear about the work people are doing with maps, GIS, geodata, and more.

  • GeoDC is turning NINE!!! Tech Talks to Celebrate!

    This month is extra special for the GeoDC community: we are celebrating our ninth birthday! We hope you can join us to have some fun, network with old friends, meet some new ones, and listen to some great talks. Never attended before? Now's a great time to start! We are one of the largest geospatial networking events in the D.C. metro area, which itself is one of the largest concentrations of geospatial professionals in the world. Our last Meetup had over 80 attendees from industry, government, startups, academia, non-profits, and everything in between. We are a community nine years strong, and with no end in sight! (For your old-timers, try and remember which Meetup you first attended. You may be asked... hint.) Think we're taking a month off because of our birthday? Nope! We have a terrific lineup of presenters: Drew Zachary from the U.S. Census Bureau will talk about The Opportunity Project, an awesome initiative where developers, mappers, and data scientists collaborate with government and communities to solve big problems using open data. Starting in August, she is working on a #GEOCOHORT where she will use geospatial data and tech to solve problems like the opioid epidemic, Puerto Rico recovery efforts and more. Join and participate! https://opportunity.census.gov/ Julian Simioni, co-founder of Cleared for Takeoff and formerly Senior Software Engineer on the geocoding team at Mapzen, will present an amazingly-titled talk: "2, 4, 6, 8, Here's how we Interpolate" about the challenges of global address interpolation. Eric McDonald will present about GeoWave, an open source tool for storing, analyzing, and visualizing large spatiotemporal datasets. https://github.com/locationtech/geowave Agenda: - 7:00: Networking - 7:30-8:00: Lightning talks - 8:00-?: More networking!
