#4005: i.sentinel.mask: use raster based approach for shadow detection -----------------------------+------------------------- Reporter: sbl | Owner: grass-dev@… Type: enhancement | Status: new Priority: normal | Milestone: Component: Addons | Version: unspecified Keywords: i.sentinel.mask | CPU: Unspecified Platform: Unspecified | -----------------------------+------------------------- Detection of cloud shadows can be quite time consuming at times, esp. with many clouds and shadows in an image.
The performance of the process could be improved by orders of magnitude, if a raster based approach (r.reclass.area + r.region + r.stats) would be used, instead of going through vector data (r.to.vect + v.clean + v.transform + v.to.db). In most cases, a raster mask is needed anyway in the processing chain downstreams... -- Ticket URL: <https://trac.osgeo.org/grass/ticket/4005> GRASS GIS <https://grass.osgeo.org>
