Planet updated the way that it selects and composites SkySat "anchor frames" or Scenes. Hence now SkySatCollects which would have previously faulted or been truncated due to faulty anchor frame selection will now publish to their full extent, potentially allowing gaps in the imagery. Note, faulty imagery will publish to the archive, however will not qualify to fulfill revenue orders.
The resolution limit over Israel has been updated from 2m to 0.4m, hence full resolution SkySat products may now be produced over Israel. This applies to both new captures and archive imagery.
Surface Reflectance (SR) assets will now be published for all SkySat images (including archive), except where MODIS imagery did not overlap the SkySat AOI on the same day as capture. The SR assets will be available for both SkySatScene and SkySatCollect item-types, as the new asset-type ‘analytic_sr’. However note SR assets will not be available in Explorer or the Command Line Interface until the end of February.
A new SkySat asset, the ‘basic_l1a_all_frames’ (aka All-Frames) is now available under the SkySatCollect item-type. This asset is published for all SkySat imagery dating back to October 2017. The All-frames asset includes all of the originally captured frames in a Collect, up to 50 frames per second, uncalibrated and in a raw digital number format. Delivered as a zip file containing all frames as basic L1A panchromatic DN imagery files, with accompanying RPC txt files, and a JSON pinhole camera model.
Planet Explorer now displays both the 'gsd' and 'pixel_resolution' parameters for both SkySatScenes and SkySatCollects. The 'gsd' parameter represents the ground sample distance of the basic SkySat product, whereas the 'pixel_resolution' parameter represents the resampled resolution of the orthorectified assets.
The SkySat cloud_cover field is now computed as the sum of cloud_percent and heavy_haze_percent so all cloud values are consistent. Note that cloud_cover is still in the range 0-1 (a ratio), while cloud_percent and heavy_haze_percent are percentages in the range 0 to 100. The properties of the archive have not been changed at this time, but may be changed in the future to also reflect this change.
