There is a new paper (open access) describing a novel method to estimate sub-pixel planimetric displacements between two DEMs:
Riazanoff, S.; Corseaux, A.; Albinet, C.; Strobl, P.A.; López-Vázquez, C.; Guth, P.L.; Tadono, T. Best BiCubic Method to Compute the Planimetric Misregistration between Images with Sub-Pixel Accuracy: Application to Digital Elevation Models. ISPRS Int. J. Geo-Inf. 13, 96. https://doi.org/10.3390/ijgi13030096
So you want to post something to geomorphometry.org? Excellent!
The posts themselves are quite simple to make. Just write it using markdown and it should work. If you’re new to markdown, this guide can help you with the first steps.
There is a new paper (open access) by the DEMIX workgroup on a global ranking of the global DEMs:
Bielski, C., López-Vázquez, C., Grohmann, C. H., Guth, P. L., Hawker, L., Gesch, D., Trevisani, S., Herrera-Cruz, V., Riazanoff, S., Corseaux, A., Reuter, H. I., & Strobl, P. 2024.
