+# Simple Extraction Tools
 Simple extraction tools remote module developed in the framework of Theia-Geosud
+
+# Contents
+This remote module of Orféo ToolBox contains some useful filters and stuff for remote sensing image processing. 
+
+## CacheLessLabelImageToVectorData
+This mapper produces an output vector data layer. The input pipeline it triggered using streaming to avoid caching the entire bulk of data on the largest possible region of the pipeline output. It's largely inspired from the OTB ImageFileWriter, but uses the LabelImageToVectorData filter to vectorize the label image. Work only on integer images (not vector images!).
+
+## RegionComparator
+A set of useful functions, maybe already existing somewhere in the OTB. Images layout, region intersection, coordinates conversion of regions, etc.
