Venus: How Does GIS Help in the Mapping of the Planet Venus

If you don’t already know, GIS (geographic information system) has enabled researchers and scientists to get a clear picture of all planets. In fact, the technology has reached a point where researchers can get a 3D picture of the planets. GIS has made it possible for scientists to learn more about the geographical features of venus. The tool gives you better images of the planet, along with the geological maps, and other details. The close-up view of the surface tells you everything you need to know about how venus looks and what components the planet’s surface is made of. It would have never been possible to penetrate those thick clouds without geospatial technology. The satellite in space is equipped with cameras and sensors that click 3D photos of the venus’ surface and give you a better look at the planet. Once the scientists collect the pictures of the venus surface, they group them and identify the materials present in the Venusian surface. The radar-based observations and the GIS technology have enabled researchers to get photos of the Venusian surface despite the thick layer coating. The researchers could only know that the venus is surrounded by a thick coating, but they did not get a picture of the surface of the planet. Venera The Soviet Union launched by Venera became the first tool to land on venus - the project that started in 1961 and continued till 1984. The Venera made a soft landing on the planet, but it could last for only 23 minutes. The probe got destroyed by the venus’ atmosphere. However, these 23 minutes were sufficient for the probe to collect high-quality and crystal-clear pictures of the venus surface and the surroundings. It sent the photos of the venus, along with the photos of the area where it landed. InSAR - A New Venus Mapping Project The use of InSAR for researching Venus and getting more information about this planet has gotten approval from authorities. However, InSAR (Interferometric Synthetic Aperture Radar) will not be used for surface mapping. This time the researchers are going to deploy it to record the movements of the surface during a natural disaster, like an earthquake. InSAR will record the venus surface twice - before and after the disaster. This will help reveal the changes in the terrain, giving scientists a better idea of the Venusian surface and how it changes. So far, the SAR image gives high-resolution photos, even though it produces black and white images. The SAR does not point downwards, its angle is rather on the side around 10 degrees to 45 degrees. The scientists and astronauts have a detailed view of the venus with high-resolution pictures of the planet collected by the SAR. It provides 75/m pixel, which is by far the best resolution quality for the venus surface mapping. GIS has not only been used for Venus mapping but the technology is used a lot for mars and other planets as well.
