Landsat 7, launched on April 15, 1999, is the latest satellite of the Landsat program. Landsat 7's primary goal is to refresh the global archive of satellite photos, providing up-to-date and cloud-free images. The Landsat Program is managed and operated by the USGS, and data from Landsat 7 is collected and distributed by the USGS. The NASA World Wind project allows 3D images from Landsat 7 and other sources to be freely navigated and viewed from any angle. The satellite's companion, Earth Observing-1, trails one minute following the exact orbital characteristics.
Landsat 7 was designed to last for five years, and has the capacity to collect and transmit up to 532 images per day. It is in a polar, sun-synchronous orbit, meaning it scans across the entire earth's surface. With an altitude of 705 kilometres +/- 5 kilometres, it takes 232 orbits, or 16 days, to do so. The satellite weighs 1973 kg, is 4.04 m long, and 2.74 m in diameter. Unlike its predecessors, Landsat 7 has a solid state memory of 378 gigabits (roughly 100 images). The main instrument on board Landsat 7 is the Enhanced Thematic Mapper Plus (ETM+).
On May 31, 2003 the Scan Line Corrector (SLC) in the ETM+ instrument failed. The SLC consists of a pair of small mirrors that rotate about an axis in tandem with the motion of the main ETM+ scan mirror. The purpose of the SLC is to compensate for the forward motion (along-track) of the spacecraft so that the resulting scans are aligned parallel to each other. Without the effects of the SLC, the instrument images the Earth in a "zig-zag" fashion, resulting in some areas that are imaged twice and others that are not imaged at all. The net effect is that approximately 22% of the data in a Landsat 7 scene is missing when acquired without a functional SLC.
Landsat 7 continues to acquire data in this mode. Data products are available with the missing data optionally filled in using other Landsat 7 data selected by the user. To continue the Landsat legacy, studies are underway to fly an equivalent scientific sensor on a new satellite.
EarthOnDrive/WavGen is partnered to deliver high quality world geodata coverages for the Tour de France 2021 once again. We have delivered geospatial data covering the 52 departments in France and we have Trimaran and Terra Media utilizing our software WavGen 3D Studio Max for the event.

The 2021 Dakar Rally was the 42nd edition of the event and the first edition held in Saudi Arabia. The event started in Jeddah on 5 January and finished in Al-Qiddiya 17 January after 12 stages of competition. The rally was marred by the fatal accidents of Portuguese motorcyclist Paulo Gonçalves on stage 7 and Dutch motorcyclist Edwin Straver on stage 11. After 11 years in South America, the event was held in the Asian continent for the first time ever. Organizers admitted that there was "hesitation" before the decision to hold the event in a country which has been under fire over human rights..
