[GRASS-user] S.K. Jenson and J.O. Domingue (1988) method to filter the elevation map

I assume you refer to:
https://grass.osgeo.org/grass78/manuals/r.fill.dir.html<https://grass.osgeo.org/grass79/manuals/r.fill.dir.html>

There is also:
https://grass.osgeo.org/grass78/manuals/r.terraflow.html<https://grass.osgeo.org/grass76/manuals/r.terraflow.html>
and
https://grass.osgeo.org/grass76/manuals/addons/r.hydrodem.html
as well as a couple of AddOns based on richdem (starting with r.richdem.*):

Maybe that helps. Can you inform us about the new methods you had in mind?

GRASS GIS manual: r.hydrodem<https://grass.osgeo.org/grass76/manuals/addons/r.hydrodem.html>
DESCRIPTION r.hydrodem applies hydrological conditioning (sink removal) to a required input elevation map. If the conditioned elevation map is going to be used as input elevation for r.watershed, only small sinks should be removed and the amount of modifications restricted with the mod option. For other modules such as r.terraflow or third-party software, full sink removal is recommended.

Emne: [GRASS-user] S.K. Jenson and J.O. Domingue (1988) method to filter the elevation map

Hello everyone,

I'd like to know if Grass still uses the S.K. Jenson and J.O. Domingue
(1988) method to filter the elevation map, in its original conception. I've
read about some new and more improved methods and was wondering if there
wasn't any improvement in Grass method.

Thank you.
