PSScene3Band

PlanetScope 3-band multispectral basic and orthorectified scenes. This data set includes imagery from PlanetScope-0 and PlanetScope-1 sensors as well as full-frame and split-frame PlanetScope-2 sensors. Newer PSScene3Band items have a corresponding PSScene4Band item.

Products Overview

The visual and analytic products are in GeoTIFF format and the basic scene products are available as either NITF or GeoTIFFs. The GeoTIFFs are resampled at 3 meters and projected in the UTM projection using the WGS84 datum. An alpha mask is provided as a binary color channel, and can be used to remove or hide low quality pixels near the periphery of a given scene. This mask compensates for effects due to vignetting, low SNR, or hot or cold pixels.

PlanetScope satellites collect imagery as a series of overlapping framed scenes, and are not organized to any particular grid system. The Ortho Scene products enable users to create seamless imagery by stitching together PlanetScope Ortho Scenes of their choice and clipping it to a tiling grid structure as required.

The PlanetScope Ortho Scene product is orthorectified and is designed for applications that require imagery with an accurate geolocation and cartographic projection. It has been processed to remove distortions caused by terrain and can be used for cartographic purposes. The Ortho Scenes are delivered as visual (RGB) and analytic products. Ortho Scenes are radiometrically, sensor, and geometrically corrected products that are projected to a cartographic map projection. The geometric correction uses fine Digital Elevation Models (DEMs) with a post spacing of between 30 and 90 meters.

Ground Control Points (GCPs) are used in the creation of every image and the accuracy of the product will vary from region to region based on available GCPs.

Product band order:

  • Band 1 = Red
  • Band 2 = Green
  • Band 3 = Blue
