Can any one tell me from where I can buy commercial High resolution Satellite images for Biodiversity research ? I need some websites that sells these kind of images ?

2What spatial resolution are you looking for, what geographic coverage, what sort of repeat time, and what is your budget :D. This will help people to answer, as there are global sources, regional sources and national sources.– John PowellFeb 9, 2015 at 15:27

And welcome to GIS SE. You will get better answers with more specific questions, was what I was trying to say.– John PowellFeb 9, 2015 at 15:41

Thanks John, I just want to know where I can buy these kinds of HR images, as there are different companies when I do search on internet.– Muna LearnFeb 9, 2015 at 16:53

Do you think about take your own photos with drone or some kind of uav for specifi places?– Ömür BilgiliOct 17, 2017 at 7:45

Two of the best commercial high resolution multispectral products available are Worldview-2 and Worldview-3. These sensors are commonly used for natural resources and biodiversity applications. You can learn more about these products here. Another more cost efficient option is to use RapidEye medium resolution imagery (details). Of course, if your budget allows you can acquire LiDAR data for your study area. LiDAR in combination with multispectral data will allow you to make predictions based on structural and spectral properties.

@Pau, GeoEye may be useful in combination with LiDAR. Although the spectral resolution on GeoEye alone limits its application in biodiversity research.– Aaron ♦Feb 9, 2015 at 20:54
Here it is the list of some high resolution imagery providers and resellers:
- https://www.digitalglobe.com/
- https://earthexplorer.usgs.gov/
- http://www.intelligence-airbusds.com/en/4871-browse-and-order
- https://www.planet.com/
- http://catalog.sovzond.ru/
- http://search.kosmosnimki.ru/
- http://www.imagesatintl.com/high-resolution-satellite-imagery/
- http://www.si-imaging.com/purchase/
The biggest data provider is DigitalGlobe. They also have the arguably best satellite (WorldView-3). You can buy directly from them, or you can go through one of the many resellers. A price of around 16$ per sqkm is usual for 4 spectral bands and 20$ for 8-bands - link to list with prices.
A slightly cheaper option is Pleiades and SPOT data from Airbus D&S. Only 4 bands available.
Furthermore, you can also go for RapidEye. A 5 meter resolution is still good for many projects, but the level of detail is not near that available from DigitalGlobe or Airbus.
