The term “Pixel identification” refers to a classification of a measurement made by a space borne radiometer, for the purpose of identifying properties of the measurement which are influencing further algorithmic processing steps. Most importantly is the classification of a measurement as being made over cloud, clear sky land or clear sky ocean surfaces. Depending on the downstream processing steps some additional properties like cloud or mountain shadow, snow cover or aerosol contamination are needed.
IdePix is a multi-sensor pixel identification tool available as a SNAP (Sentinel Application Platform) plugin. It provides pixel identification algorithms for a wide variety of sensors like Sentinel-2, Sentinel-3, MERIS, Landsat-8, MODIS, Proba-V or SPOT VGT, just to mention a few. It is therefore a one-stop pixel identification tool if you are working with multiple sensors. As a SNAP plugin, it can be used in combination with other algorithms available from S2 & S3 toolbox, to create powerful processing chains with SNAP or GPT (Graph Processing Tool).
