No output after running step one of Water Bodies Mapping - Radar #3

Hi, I am trying to run the first step of water bodies mapping (radar), using WOIS and after selecting all the required parameters, the process runs well but without an output (or an error result). I am using sentinel 1 image GRD for the step. Whatt could be the issue?

Hi, Maybe you cannot download the orbit file. It could be that your firewall is blocking the access to the required server or your SNAP is out of date and the address of the server with orbit files has changed. However, in case of S1 this step is not very important so your could try skipping it.

Also, please consider switching to the GlobWetland-Africa toolbox since WOIS is not being actively supported at the moment. GlobWetland Africa Toolbox contains an Inundation Regime workflow which you could use to map water bodies with SAR and optical data.

@radosuav Thank you for introducing me to GlobWetland-Africa toolbox. I guess it is a plug in in QGIS. Will try using it.

Technically it is very similar to WOIS. So it consists of QGIS, SNAP, R, etc. plus QGIS plugins, workflows, models and scripts. But the focus is on wetland inventorying and monitoring, rather then water resources management as was the case for WOIS.
