ISPRS 2020 paper : Can SPOT-6/7 CNN semantic segmentation improve SENTINEL-2 basedland cover products? Sensor assessment & fusion
This page present inference results in new format for a better understanding of our statements and conclusions. Each of the 3 main comparisons have a dedicated tab containing :
- Metrics bar charts of test dataset
- Maps of train, validation and test datasets
Full camera-ready paper is available here.
Enhanced visualisation of inference results
Sensors assessment between SPOT-6/7 and SENTINEL-2 : 6 classes experiment
Maps for fusion data is currently not available and will be online after quartine.
Sensors assessment between SPOT-6/7 and SENTINEL-2 : 18 classes experiment
OSO map enhancing with CNN SPOT-6/7 fusion experiment
Please keep in mind that we used SPOT images with 1.5m and 6m pixel resolution respectively for panchromatique and RGB sensors. Google aerial images displayed here are 0.25m pixel resolution on RGB sensors. They where not involved into calculations and are only here to give a ground thruth to the reader and to improve results understanding.
The OSO map shown is a special inference processed only on the displayed SENTINEL-2 tile and thus may differ from the France-wise inference.
Use the border color of graph bar to get nomenclature color of the maps.
- Graph : you can remove a set by clicking on its legend.
- Maps : Opacity control on the bottom left impact all train/validation/test dataset of the given inference.
Inference maps where generated thanks to GDAL. Maps are displayed with Leaflet library and grouped layer control plugin (slightly modified by myself). Graph are genreted with Chartjs library.
OSO Map is available at OSO Distribution and is generated by CESBIO.
