Examples of commonly used satellite resolution clarity.
The resolution of the satellite imageryThe clarity is determined, and the current maximum resolution of the satellite is 03 meters, in order: 03 meters" 05 meters" 08 meters" 1 meter "15 meters, 2 meters, 4 meters, 10 meters, 15 meters, 30 meters, and 60 meters.
At present, the highest resolution of the satellite is taken by the French PNEO satellite, the American WorldView3 satellite, and the Chinese SuperView-NEO and Jilin-NEO satellitesThe 3-meter resolution satellite image has the highest definition, which can identify the details of houses and roads, and can be used for planning and design projects in a small area of the main urban area of the city. This was followed by 0Satellite imagery with 5-meter resolution, the most data, is updated almost every month. In addition, there is 08-meter satellite image, taken by the French spot6 satellite5-meter resolution satellite imagery, 2-meter resolution satellite imagery taken by China's GF1 series satellites, and 3 4-meter resolution Planet satellite imagery taken almost daily.
"With so many resolutions, how do I choose? "If you need a small area (such as a house, a park, or a field) and you need to see the details of the house's field, then it is recommended0.3 meters and 05 metersResolution.
If you need a medium area, such as an urban area of a city or tens to hundreds of square kilometers, and you want to see things such as houses and farmland, then it is recommended0.5–1.5 metersSatellite imagery of resolution.
If you need a large area, such as the entire range of a county or a prefecture-level city, thousands or even tens of thousands of square kilometers, and the clarity requirements are not particularly high, then it is recommended to choose1 2 metersSatellite imagery of resolution.
If you need a large area, such as a province, or your budget is low, only a few thousand yuan, but you want to buy a large area of satellite images, then it is recommended to choose10 15 metersResolution satellite imagery.
0.3 meter resolution satellite image clarity.
