Next-Generation Planetscope imagery will now be published as both standard and test quality. 3 and 4 band data will be available through the existing PSScene3Band, PSScene4Band, and PSOrthotile items. Additionally, 5-band (blue, green, red, rededge, nir) imagery is available under the analytic_5b asset, which is in the PSOrthotile item type. The way to identify data in this release is by the "psb.sd" value in the "instrument" field.
See https://developers.planet.com/docs/data/items-assets/ for details on Items/Assets.
An Image Quality Report on data contained in this release is available at https://assets.planet.com/docs/Planet_Combined_Imagery_Product_Specs_letter_screen.pdf.
Planet is improving its algorithm for calculating Surface Reflectance in PlanetScope and RapidEye products. Planet is also now producing
analytic_sr assets under the existing
REOrthoTile item types.
The new Surface Reflectance algorithm should help reduce scene-to-scene difference due to rapidly varying atmospheric conditions. Reference the updated white paper on the support page: https://support.planet.com/hc/en-us/articles/360012629573-Planet-Surface-Reflectance-Product
analytic_sr assets are available under the existing
REOrthoTile items listed in the Dev Center: https://developers.planet.com/docs/data/items-assets/
UDM and UDM2 files for SkySatCollect items no longer have their nodata value set to 1
Pansharpened and Visual SkySat data product generation has been updated. The scaling of the BGRN pansharpened products is reduced to the scaling of the multispectra (a 16x reduction in DN values)
