Q-GlaRe+ QGIS 4 compatibility
Not QGIS 4 ready Active
Not yet — the latest version declares max QGIS version 3.99.0, so it is not offered to QGIS 4 users.
Q-GlaRe+ reconstructs the 3D surface elevation and ice thickness of palaeo- and extant glaciers from digitised flowlines, and facilitates calculation of Equilibrium Line Altitude (ELA).
About
Q-GlaRe+ is a QGIS plugin for reconstructing the 3D surface elevation and ice thickness of palaeo- and extant glaciers and calculating their Equilibrium-Line Altitude (ELA). It adds a Q-GlaRe+ provider to the Processing Toolbox with five tools for flowline ice-thickness estimation, manual and shape-factor corrections, 3D surface interpolation, and ELA calculation. Main tools: - 2D FL Ice Thickness: estimates ice thickness and surface elevation along digitised flowlines - 2D modified FL Ice Thickness: adjusts individual flowline point values (e.g. basal shear stress) - 2D shape-factor FL Ice Thickness: applies a valley shape-factor (F-factor) correction - 3D Interpolation: interpolates the flowline estimates into a continuous glacier surface and ice-thickness raster. - Q-ELA: calculates the ELA by the AABR, AAR, and AA methods. External dependencies (must be installed before use): the 3D Interpolation tool requires SAGA GIS and the Processing Saga NextGen Provider plugin, installed and configured separately. numpy and pandas are included with standard QGIS / OSGeo4W installations. The other tools run without SAGA. How to cite: Burnham, B. S., M. Spagnolo, R. Pellitero, et al. 2026.
