the task file for the remote sensing task is currently sar.
I don't know if the task file name has any relevance in the process
of metapackages generation.
The metapackage becomes: gis-sar.
If it does you should consider to rename the task file: remote
sensing is a wider scope with respect to SAR (Synthetic Aperture
Radar)
We should decide about a proper name right now because there is not yet
any debian-gis metapackage set released. Once it is released with this
name it becomes harder to change afterwards. I'm fine with any choice
that makes a proper (i.e. not too longish) package name.
