In the habitat quality module of INVEST 3.15.1, is the unit of MAX_DIST in the threat settings **meters (m)? I noticed that previous tutorials used kilometers (km) .
Hi @sunflower, and welcome to the forum!
As of InVEST version 3.15.0, the expected unit for MAX_DIST is meters. Prior to 3.15.0, the model expected kilometers, which is why you’ll see km in older tutorials. The change to meters was made to align with distance measurement parameter units used across InVEST models.
I would like to confirm from which version of the InVEST model the unit of max_dist was adjusted to kilometers.I am currently using InVEST 3.16.0. May I ask if you are an official member of the development team?In previous reference academic papers, this parameter was always interpreted with kilometers as the default unit.
I need to explain this situation to the reviewers.
Hi @yik,
I am a member of NatCap’s Software Team. Prior to InVEST 3.15.0, max_dist values in the threats table were expected to be in kilometers. Beginning with InVEST 3.15.0 (released 2025-04-03), InVEST has expected max_dist values in meters. You can find reference to this change under the “Habitat Quality” header for the 3.15.0 release in our HISTORY.rst and the related GitHub issue is available here.
