On July 2, 1967, at 14:19 UTC , the Vela 4 and Vela 3 satellites detected a flash of gamma radiation unlike any known nuclear weapons signature.  Uncertain what had happened but not considering the matter particularly urgent, the team at the Los Alamos Scientific Laboratory , led by Ray Klebesadel , filed the data away for investigation. As additional Vela satellites were launched with better instruments, the Los Alamos team continued to find inexplicable gamma-ray bursts in their data. By analyzing the different arrival times of the bursts as detected by different satellites, the team was able to determine rough estimates for the sky positions of sixteen bursts  and definitively rule out a terrestrial or solar origin. The discovery was declassified and published in 1973 as an Astrophysical Journal article entitled "Observations of Gamma-Ray Bursts of Cosmic Origin".  This alerted the astronomical community to the existence of gamma-ray bursts (GRBs) , now recognised as the most violent events in the universe.
The elevation data is provided by the Google Elevation Service, the raw data for that were originally obtained during the Shuttle Radar Topography Mission (SRTM) : The freely available SRTM data consists of SIR-C data from NASA and X-SAR data of the German Aerospace Center (DLR). The SIR-C data have a height accuracy of about 6m on at a horizontal resolution of about 30m . The X-SAR data should indeed have a higher accuracy up to 1m, but cover only 40% of the earth's surface. Which of these elevation data are actually provided through the Google Elevation API is not known to us. Geoplaner rounds Googles elevation values to a precision of or 1ft. This allows to recognise elevation differences between waypoints which lie very close to each other.
