New geometric processing: Projected

The image acquired in the plane of the sensor is projected onto a cartographic or geographic terrestrial plane. The plane is defined with a constant altitude, which is the mean height value over the area of interest.
Projected products include all the radiometric and geometric corrections of the Primary level (external orientation). An associated geometric model is described in an RPC file that can be directly integrated into image processing and analysis software.

Main benefits for users:

- Directly compatible with GIS environments
- Easier orthorectification by users who use their own reference layers (Ortho, GCPs and DEM…) thanks to the geometric model described in the embedded RPC file

New Radiometric processing: Reflectance

The image is radiometrically corrected from sensor calibration and systematic atmospheric effects (molecular or ‘Rayleigh’ diffusion). Cloud, cloud veil, haze, aerosol (pollution and sandstorm) remain.
Image values are provided in normalized reflectance values with a 1/10,000 ratio.

Main benefits for users:

- Correct the bluish effects from the atmosphere
- Obtain reliable true colors
- Ensure more stable luminosity/contrast on screen
- Prepare direct near seamless coverage (eg. Mosaicking…)

New Radiometric processing: Display

Display level products are generated from a new algorithm based on the Reflectance product. The Display level replaces the former OVR (Optimized Visual Rendering) option.
8-bit pixel coding should be requested since 16-bit pixel coding does not provide any additional information. Moreover, image files are lighter with 8-bit pixel coding.
Display processing should be selected when images need to be immediately displayed on screens with optimized visual rendering.

New product available in GeoStore: Best of SPOT 1.5m!

Select the  product in the SPOT archive product collection and display directly in GeoStore the freshest and cloud-free images on your AOI in a few clicks. These images have been manually selected by Airbus Defence and Space imagery experts.

New: Upload your polygon names directly in GeoStore!

You can now import the native names of your AOIs directly from your Shapefile or KML/KMZ. This option is very useful if you have a lot of AOIs to cover, simply extract the site locations from your own GIS and batch upload them into GeoStore.

Click on  and select  to upload a KML/KMZ file or   to upload a Shapefile.

If you are uploading a Shapefile, make sure to select all the related file types (.shp .dbf .shx .prj) by maintaining the SHIFT or CTRL key while clicking.

Then click on the switch button to select “Yes”, choose the field name to import and click on “OK” to start the upload.

Note that if you are uploading a KML/KMZ file, only the “Name” attribute will be selectable.
