About
QGIS plugin to generate topographic longitudinal profiles from vector alignments and Digital Terrain Models (GeoTIFF, ASC, IMG, BIL, FLT, DEM, HGT — any GDAL-supported format). Supported alignment formats: DXF, SHP, KML, KMZ, GeoPackage, GML, GPX, GeoJSON. Automatic CRS reprojection (e.g. WGS84 axis over UTM DTM). Main features: - DTM and alignment can be loaded from file/folder OR selected directly from layers already loaded in the QGIS project. - Smart DTM cache: scans folder once, reuses the index for subsequent runs. - Automatic detection of DTM tiles intersecting the alignment. - Bilinear interpolation of terrain elevations along the axis. - Configurable segmentation interval (e.g. 1 m for smooth profiles). - Longitudinal profile in standard topographic style: terrain line, comparison plane, partial/total distances in PK format (0+860) and elevations at original vertices. - Independent horizontal and vertical scales. - Automatic or fixed comparison plane. - DXF export with polylines, annotations and data table (guitar). - CSV export with partial/total distances and elevations. - Cross-section profiles: configurable spacing, width and scale. DXF grid layout with terrain, axis, PK, comparison plane and elevation table. - 3D axis export: original vertices with PK labels (horizontal text, no Z annotation) plus optional clean 3D polyline draped on DTM at segmentation interval. - DTM buffer export: GeoTIFF clipped to alignment bounding box + buffer, LZW-compressed. - Contour lines: DXF with normal and master contours, Chaikin smoothing, optional Douglas-Peucker vertex simplification (configurable tolerance) to keep straight stretches lightweight, and minimum-length filter to suppress tiny closed contours.
