Preprocessing of Planetscope 4-band imagery

This repository contains scripts for preprocessing and basic analysis of Planetscope imagery. Code is based on notebooks from Planetlabs.

Available notebooks

Preprocessing

• PS_preprocess_reflectance_images

Preprocess multiple images that does not need mosaicing.
Convert Radiance to Reflectance. Deliver images scaled/unscaled, with/without clipping to AOI (area of interest).

• PS_preprocess_reflectance_mosaic

For large AOI's that require several scenes/images (mosaic) to cover the AOI.
Convert Radiance to Reflectance. Deliver images or the mosaic scaled/unscaled, with/without clipping to AOI.

Analysis

• PS_analysis_veg_indices

Takes reflectance images as input, calculate, visualize and export vegetation indices from PS 4-band imagery.
Vegetation indices: NDVI, EVI, SAVI, MSAVI2, ARVI, IPVI, DVI, RVI

• PS_analysis_segment_threshold

Takes vegetation indices as input, apply thresholding to segment image, smoothen with majority filter and export mask.
