Hi @Neetu and welcome to the forum! Please take a look at this post: Guidelines for posting software support questions and share, at minimum, your logfile.
However, the carbon stock maps for 2015 and 2020 appear exactly the same, with no visible changes between them.
Have you opened the maps in a GIS and inspected the values to confirm they are identical? Or better, computed a difference map to check if they are actually the same or just similar?
Additionally, for the years 2020 and 2025, the “low” value is showing as -inf, and the entire output map appears completely black, with no clear visualization.
Which version of InVEST are you using? This could certainly be a bug in how NoData is calculated. If possible, could you share your data?
However, the issue persists — all four maps are showing similar low-to-high ranges, and the maps look almost identical.
What are you expecting to see instead? For example, if there are no LULC changes (post-alignment), we wouldn’t expect to see a difference in the carbon maps.
Thanks
