  • Reconstructing Urban Memory of the Wenxi Fire Haoran Chang Figure 1 Photogrammetry Model
    Photogrammetry and Zhongshan Pavilion: Reconstructing Urban Memory of the Wenxi Fire Haoran Chang Figure 1 Photogrammetry model of Zhongshan Pavilion. Image courtesy of the artist. In line with the government’s scorched-earth policy, on November 12, 1938, a devastating fire was started in the city of Changsha, China. This military strategy calls for the intentional burning and destruction of all valuable resources, such as buildings, food, and transportation infrastructure, to prevent the invading enemy Refract | Volume 3 Issue 1 242 from utilizing them. During the Second Sino-Japanese War (1937–1945), the gov- ernor of Changsha followed instructions from the Nationalist government to exe- cute this scorched-earth policy. Yet officials mistakenly initiated the fire too quickly and destroyed the more-than-three-thousand-year-old city. In this fire, thousands of people lost their lives, and the majority of the city’s buildings were destroyed. Referred to today as the Changsha Fire of 1938, or the Wenxi Fire, this event left Changsha one of the most damaged cities during World War II, along- side Stalingrad, Hiroshima, and Nagasaki.1 Zhongshan Pavilion is one of the few architectural structures that survived the 1938 Wenxi Fire. As technology widely applied in cultural preservation, pho- togrammetry can play a significant role in preserving this structure for future gen- erations. Yet this project intends to further the conversation about the role of photogrammetry in memory preservation by considering the Zhongshan Pavilion as a heterogeneous site. The resulting virtual 3-D model opens new potentialities in challenging historical narratives that are told in the singular voice (the state’s) as presented at the physical site in Changsha.

  • Free-Flight Mapping with Dji Spark
    Free‐Flight Mapping: Pix4Dcapture & dji Spark Jerry Davis, SFSU Institute for Geographic Information Science The best way to do mapping is using a GPS‐guided grid pattern programmed by an app like Tower or Pix4Dcapture to ensure reliable coverage with suitable overlap, and with little user input needed during the flight. But what do you do if GPS is not reliable, such as under forest canopy, in deep canyons, or maybe in urban canyons with tall buildings degrading GPS signal? Free‐ flight mapping may be the only choice under these conditions. This guide provides a method that will work for the dji Spark, which is a light‐weight drone easily flown without GPS with a perfectly capable camera on a gimbal, but it doesn't accept a flight plan. Its obstacle avoidance, visual positioning and propeller guards make it safe flying in difficult locations with limited GPS signal. The same method could be applied to other drones that can be flown manually. Note: not described here, but you'll also need to survey in ground control points; the photos don't have accurate GPS tags. One challenging mapping task is along stream corridors where riparian canopy can be very dense. These sites can be very difficult and in the coastal selva environments we commonly encounter (e.g. in streams in San Mateo County) the vegetation can often be so dense that it's difficult to envision doing any drone‐based mapping. However many of these creeks with mature riparian canopies can be open enough below canopy to allow drone flights if we can accurately control the aircraft.

  • DJI Government Edition UAS Data Management Assurance Flight Test and Evaluation Report
    Flight Test and Technical Evaluation Report DJI Unmanned Aircraft System (UAS) Mission Functionality and Data Management Assurance Assessment U.S. Department of the Interior Office of Aviation Services Boise, Idaho by Mark L Bathrick Brad Koeckeritz July 2, 2019 This Flight Test and Technical Evaluation Report presents results of an assessment of the flight, payload, and data management assurance performance of the SZ DJI Technology Co., Ltd. Matrice 600 Pro and Mavic Pro unmanned aircraft systems (UAS) modified with DJI Government Edition (GE) hardware, firmware, and software for suitability in selected Interior bureau missions. Test articles were operated under the Office of Aviation Services (OAS) Test Plan for Validation and Verification of Data Security Software for Employment of DJI UAS Platforms, originally signed on April 9, 2018 and later updated with approved Modifications One and Two of November 14 and 16, 2018, respectively. APPROVED FOR RELEASE: Mark L Bathrick, Director Page 1 of 53 SUMMARY In 2014, following four years of unmanned aircraft systems (UAS) operational test and evaluation (OT&E), the U.S. Department of the Interior’s (DOI) Office of Aviation Services (OAS) and over 300 subject matter experts from DOI bureaus developed the Master UAS Requirements for the DOI. In 2015, while conducting UAS market research, OAS determined the privacy policy of the largest provider of UAS in the U.S. (SZ DJI Technology Co., Ltd) did not meet UAS data management assurance standards contained in the Master UAS Requirements for the DOI. Specifically, they did not meet DOI’s requirement to be able “to decline and lock out any device information sharing including telemetry through aircraft, software or applications preventing any automated uploads or downloads.” In 2016, Interior awarded its first contract for fleet small UAS to a U.S.

    OpenBot: Turning Smartphones into Robots Matthias Muller¨ 1 and Vladlen Koltun1 Abstract— Current robots are either expensive or make significant compromises on sensory richness, computational power, and communication capabilities. We propose to leverage smartphones to equip robots with extensive sensor suites, pow- erful computational abilities, state-of-the-art communication channels, and access to a thriving software ecosystem. We design a small electric vehicle that costs $50 and serves as a robot body for standard Android smartphones. We develop a software stack that allows smartphones to use this body Fig. 1. OpenBots. Our wheeled robots leverage a smartphone for sensing for mobile operation and demonstrate that the system is and computation. The robot body costs $50 without the smartphone. The sufficiently powerful to support advanced robotics workloads platform supports person following and real-time autonomous navigation in such as person following and real-time autonomous navigation unstructured environments. in unstructured environments.
