11:15a CDI FY15 Project Presentation: USGS Unmanned Aircraft System (UAS) Data Management Opportunities and Challenges - Brent Johnson, USGS
Presentation: Slides are available to CDI Members. Please login to download the slides. If you would like to become a member of CDI, please email email@example.com.
Abstract: As Unmanned Aircraft System (UAS) technologies advance, so do the sensors they carry. This results in hundreds or even thousands of gigabytes of data in a single flight. Where do these data go, who can access them, and does it adhere to standards? These and similar questions are ones that need to be addressed with the increasing use UAS technologies. This project developed mechanisms and protocols to make such data available to the public and government agencies on a streamlined, structured, and managed way. As the USGS, and other government agencies, conduct more UAS missions, we need to address how we conduct data management activities associated with data acquired by UA.
Questions & Answers
Lance: Reminds me of some other datasets that we have.I have a question about the interface for agencies and vendors to load information. What type of information are they loading and is that tied to metadata?
Brent Johnson: That will be a web form and the agency/vendor would have to enter specific metadata explaining the data and there will be a place to upload the data here, as well.
Brent Nelson: Designed so that vendors in the field would have access from the field to the site to load the data initially, so we can turn it around fairly quickly and they would then have access to all of those data from our site.
Lance: Thank you, defining vendors really helped. That was great.
Leslie: You mentioned that there are evolving sensors and evolving types and that its important to capture the metadata. Who's responsibility is it to capture the right metadata? At what point in the process do people need to start thinking about the metadata and what metadata is captured?
Brent Nelson: Yes, that is really key. Things are moving very quickly, so we are working to develop software so that it can be adapted in the future. Long term goal will be for the project or people flying the mission to enter the metadata and we are trying to make it as intuitive as possible. We will work with the vendors to ensure that we get that metadata because it is really essential to have the metadata to understand the data.
Brent: At the moment, there is not a standard, but the webform will be standardized at on our end.
Leslie: There are some teams out in the USGS who are interested in starting to use UAS technology. Do you have any advice on how to get started, especially with respect to UAS and data management?
Brent: First thing would be to get in touch with Joe Adams and I believe he is on the line.
Joe Adams: You can start exploring UAS at uas.usgs.gov. You are also welcome to call me, Josip Adams. I can help you navigate these waters and help you get started.
Leslie: Are you seeing in increase in the use of this technology?
Joe: It has been relatively level. There is a lot of buzz about UAS in the media; however, UAS are treated as aircraft within the Department of the Interior and the FAA rules and the safety protocols present a number of road blocks for the use of UAS in the USGS. We are hoping some of these rules will change here in the future; however, we have been able to get flights flown for pretty much anyone who wants this type of data for a project. Also, there have been a number of examples of projects using contractors to fly UAS flights.
Rich: Is there an established way for delivering high resolution terrain data? Is there a way to view them in a performant way in a web browser?
Joe: I have not seen a standard for online delivery of UAS data.
Brent: I do not believe there is a standard for viewing these.
Joe: This is where USGS can lead the way. Everything is moving very fast.
Rich: So that is an area where CDI can help out?
Joe: Yes, certainly. There are also a number of technology groups coming on board. ESRI is developing Drone2Map. Also, Structure from Motion is another tool out there. I expect big changes in the near future.
Leslie: Is USGS speaking with other federal agencies or organizations to see how they are dealing with their UAS data and Metadata?
Brent: Ryan Longhenry has had some other conversations with BLM but can't speak to other conversations outside of the USGS.
Joe: DOI has a GIS position open focusing on Data Management and protecting data and privacy. They are looking at that very closely don't want to get in trouble with privacy concerns. Conversations about this happening at a high level.
Leslie: We have compiled a few links about UAS in preparation for this call and discussion. There is a lot of activity out there. If you are interested in learning more about UAS activities, there are a few links on the CDI Blog to get you start. ESIP has drone cluster that meets frequently. Had a presentataion from ESRI for viewing drone technology.
Rich: Sharing a link for displaying UAS data "An experiment: drone-derived DEM+Ortho in TerriaJS: http://bit.ly/Caco_001"
11:45a Introduction to the CDI 2016 Virtual Trainings - Leslie Hsu, USGS (.pdf slides 8-10)
Leslie: Please submit your questions about reproducibility for the Workflows and Reproducibility Training so that April can address USGS-related questions during the training event. Please submit through the CDI Idea Lab
CDI Calendar now available on the wiki: CDI Calendar. Please note that default time zone for your calendar might not be your current time zone.
12:00p Working Group Reports
Last May Connected Devices discussed software release IMs and what it is going to take to do code review, especially for mobile apps. Dave G. gave briefing on EPA's work last month. Next meeting is June 23rd at 12:00pm ET. Presentation on Fisheries Harvest in developing countries and discuss their plans for mobile app development. They are trying to determine if they should use an existing app or start fresh. Also an overarching view of Angular2/Ionic2/Electron2 – building web, mobile, and desktop apps from one set of Typescript components. Background info at http://electron.atom.io/ (also built on angular) for building Windows, Linux, and OS X apps.
