TopoTrail QGIS 4 compatibility
QGIS 4 ready Active
Yes — TopoTrail supports QGIS 4 (declared max version 4.99.0).
Topographic suitability, access zones and least-cost routes for preliminary trail and field planning, from a single DEM.
About
TopoTrail is a QGIS plugin designed to support preliminary planning of new trails, access routes and field corridors in natural areas and protected areas. The tool models topographic suitability using a Digital Elevation Model, slope, curvature, relative topographic risk, suitability classes, potential access zones, suggested least-cost routes and access corridors. The plugin does not automatically detect roads, pastures, existing trails, land cover, hydrography or legal restrictions; these layers should be used as complementary evidence in QGIS. No external Python dependencies: it uses only NumPy, SciPy and GDAL/OGR, which every QGIS installation already ships. Developed by Luan da Silva Cortes Maciel (MACIEL, L. S. C.) as a product of his master's research in Biodiversity in Protected Areas, associated with the Escola Nacional de Botanica Tropical and Jardim Botanico do Rio de Janeiro, under the supervision of Leandro Freitas. Associated project: Herpeto Mantiqueira.
