Planet Labs is a new startup with a bold mission: To image the entire planet every day. In the last year alone, the company has built and launched 67 satellites, made possible with an "Agile Aerospace" approach.
The current operational constellation is successfully imaging the earth at a resolution of 3 to 5 meters. The goal is to create a much greater awareness of all that is happening on our planet. Key to this mission is greatly increasing the world's access to satellite imagery and the valuable information that can be derived from it.
The fusion of Open Source Hardware and Software have enabled the birth of interesting mapping platforms. In this session, we will walk through the process of building a drone, from scratch, using hardware platforms like ArduPilot and O.S. software like Mission Planner. We will go over all the major components, explain what they do and how they (literally) fit together. At the end of the session, we will show how to collect imagery with it and put it on a map so you can have the most recent imagery in the planet of your data collection area!
Planet Labs operates the largest constellation of earth observing satellites of any geospatial data provider. Each satellite is designed to continuously capture around one scene per second. With clouds, seasons, and a possible pointing error of up to 100 km, the Rectification Team is charged with aligning every pixel to its ground location. From experimental beginnings using GDALSimpleSURF, Planet's pipeline now includes FLANN, OpenCV, GDAL, GRASS, PROJ.4, and OSSIM.
Drones have recently received a lot of media attention for their use as a surveillance tool. Their utility for video and still aerial photography is undeniable, but legislation threatens to restrict the use of drones even for scientific purposes. But kites are rarely subject to the same restrictions, even if they are used for similar purposes. Additionally, kites fly in windy conditions that would ground a drone and flight times are limited by arm muscle endurance, not by battery life. Processing the photos from either a drone or a kite, however, follows largely the same workflow.
Description: The workshop is implemented in two segments. The first segment will introduce participants to Program R (http://www.r-project.org/) and the Integrated Development Environment (IDE) of R Studio (http://www.rstudio.com). We will begin by covering basic data management, summaries and visualization.
Earlier this year, Stamen launched parks.stamen.com, a project that collects geotagged social media content within parks and other open spaces in California. We harvest data from four major social media services (Twitter, Foursquare, Flickr, and Instagram), each of which provides a unique view into the different facets of each park, and the diverse communities who enjoy these parks.
The San Francisco Municipal Railway is the public transit system for the city and county of San Francisco, and is responsible for operating buses, light rail, and the world famous cable cars. Although route schedules are prefaced with the modifiers "Inbound" and "Outbound", Muni's use of these terms often has little to do with their generally understood meaning.
