RT journal article T1 Q–Str2–Models: A software in PyQGIS to obtain Stress–Strain models from GNSS geodynamic velocities A1 Ramírez Zelaya, Javier Antonio A1 Peci, Luis Miguel A1 Fernández Ros, Alberto A1 Rosado Moscoso, Belén A1 Pérez Peña, Alejandro A1 Garate Pasquín, Jorge A1 Berrocoso Domínguez, Manuel A2 Matemáticas K1 Strain rate K1 Stress–Strain models K1 Earth deformation K1 Interpolation K1 Geodetic deformation software AB Q–Str2–Models is an opensource application developed in Python (PyQGIS) and integrated into QGIS that provides us with several tools for creating Stress–Strain models in geodynamically active areas, from the calculation of the horizontal velocities of many points from a temporal or permanent GNSS network. This software generates the results of the maximum geodetic deformation, shear deformation, rotation and dilatation of the points, which are later translated into graphic products; heatmaps, displacement vectors and Stress–Strain tensors. In this article we show the results of the application of Q–Str2–Models for the analysis of 65 GNSS stations of SPINA (South of the Iberian Peninsula and North Africa) network to know the geodynamic behavior of the Andalusian region and its surroundings. © 2023 The Authors PB ELSEVIER SN 0098-3004 YR 2023 FD 2023-03 LK http://hdl.handle.net/10498/27988 UL http://hdl.handle.net/10498/27988 LA eng DS Repositorio Institucional de la Universidad de Cádiz RD 11-nov-2026
