PLANET Labs PBC 20227 GLOSSARYThe following list defines terms used to describe PLANET s satellite IMAGERY MaskAn alpha mask is an image channel with binary values that can be used to render areas of the image producttransparent where no data is Programming Interface (API)A set of routines, protocols, and tools for building software CorrectionThe process of correcting at-sensor radiance IMAGERY to account for effects related to the interveningatmosphere between the earth s surface and the satellite.
8 Atmospheric correction has been shown tosignificantly improve the accuracy of image pixels or pixels outside of the buffered area of interest that are set to black. They may appear aspixels with a value of 0 or as noData depending on the viewing Elevation Model (DEM)The representation of continuous elevation values over a topographic surface by a regular array of z-values,referenced to a common datum. DEMs are typically used to represent terrain standard for encoding geospatial data using JSON (see JSON below).GeoTIFFAn image format with geospatial metadata suitable for use in a GIS or other remote sensing Sample Distance (GSD)The distance between pixel centers, as measured on the ground.
9 It is mathematically calculated based onoptical characteristics of the telescope, the altitude of the satellite, and the size and shape of the CCD User Interface (GUI)Web based interfaces enable users to interact with PLANET 's IMAGERY products without needing knowledge ofhow to use APIs or Application Programming Object Notation (JSON)Text-based data interchange format used by the PLANET 8 Freely available dataset offered through NASA and the United States Geological delivered with PLANET s IMAGERY products that describes the products content and context and can beused to conduct analysis or further processing. PLANET Labs PBC 20228 NadirThe point on the ground directly below the (NIR)Near Infrared is a region of the electromagnetic process of removing and correcting geometric image distortions introduced by satellite collectiongeometry, pointing error, and terrain TileOrtho Tiles are PLANET s core PRODUCT lines of high-resolution satellite images.
10 Ortho tiles are available in twodifferent PRODUCT formats: Visual and Analytic, each offered in GeoTIFF first three generations of PLANET s optical systems are referred to as PlanetScope 0, PlanetScope 1, andPlanetScope CorrectionThe correction of variations in data that are not caused by the object or image being scanned. These includecorrection for relative radiometric response between detectors, filling non-responsive detectors and CoefficientThe reflectance coefficient provided in the metadata is used as a multiplicative to convert Analytic TOAR adiance values to TOA refers to the five-satellite constellation operating between 2009 and single image captured by a PlanetScope CorrectionThe correction of variations in the data that are caused by sensor geometry.
