        At present, the most commonly used high-resolution satellite image in the world is WORLDVIEW A series of , It is famous in the satellite remote sensing circle , It not only has ultra-high resolution, but also has what other high-resolution satellites do not have 8 Band , Unlimited scenery . At present, the resolution is only WORLDVIEW3 and WORLDVIEW4 Can achieve 0.3 Meter resolution , The ground observation is clearly visible . Beijing mapus technology has fully represented a series of WORLDVIEW Satellite imagery , It can process satellite images 、 Interpretation, etc , The following is the above picture to prove the image effect .

      at present Geographic remote sensing ecological network platform High resolution satellite remote sensing image data has been released .

     WorldView-1 On 2007 year 9 month 18 Solar launch successful ,WorldView-2 On 2009 year 10 month 8 Solar launch successful ,WorldView-3 On 2014 year 8 month 13 Solar launch successful .

    WorldView-1 After launch, it has become the highest resolution in the world 、 The most responsive commercial imaging satellite , Space borne large capacity panchromatic imaging system can shoot up to 50km² Of 0.5 Meter resolution image . The satellite will also have modern geographic positioning accuracy and excellent response ability , It can quickly aim at the target to be photographed and effectively carry out the same orbit stereo imaging .

    WorldView-2 The spaceborne multispectral remote sensor on the satellite not only has 4 Industry standard spectrum segment （ red 、 green 、 blue 、 The near infrared ）, It also includes four additional bands （ coast 、 yellow 、 Red edge and near infrared 2）. The diversity of spectral bands can effectively provide the ability to accurately detect and map changes , because WorldView Satellites respond faster to commands , So the turnaround time of the image （ The time from giving imaging instructions to receiving images ） Just a few hours, not a few days . The satellite can provide 0.46 Meter panchromatic image and 1.8 Meter resolution multispectral image .

   WorldView-3 It is currently the satellite with the highest spatial resolution among commercial imaging satellites , The spatial resolution reaches 0.31m. Its photographic image continues WorldView-2 Provided 8 Spectrum of bands , And added 20 Special bands , Include 8 A short wavelength infrared band , It is more conducive to the classification and detection of special features . in addition 12 Bands are distributed from visible light to invisible light CAVIS-ACI Band , Conducive to rain and fog detection 、 Image restoration and obtaining more correct ground reflectance .

    WorldView-4 The satellite is in Eastern time 2016 year 9 month 26 The morning of 11 spot 30 It was launched from Vandenberg Air Force Base .WorldView-4 Can shoot panchromatic 0.3 Meter resolution and multispectral 1.24 Meter resolution image .
