{"name": "Granulometria por Fotointerpretacion", "package_name": "GranulometriaPorFotointerpretacion", "description": "Measures rock grain sizes in a photo by photointerpretation and exports gradation reports.", "about": "Granulometria por Fotointerpretacion (Photointerpretation Grain Size Analysis) measures the size of rock grains in a georeferenced photo, typically captured by drone. The user draws the photo outline to obtain the total area, then draws or adjusts grain polygons (for example, produced by a segmentation tool such as GeoAI/Segment Anything). The plugin filters grains by a sieve-size threshold - grains below it are removed from the polygon layer and their area is counted as fine material - computes coarse/fine areas and percentages, and exports: (1) an Excel workbook with area/diameter data in a fixed template layout, (2) a second Excel workbook with image and material summary information, and (3) a GeoPackage bundling the polygon layer, the source photo raster, and an embedded QGIS project, exported as-is in the project's coordinate system (no reprojection). It also offers an optional lossless cropping step and a photo-labelling tab (date, free text and your own logo) for report evidence. No external Python packages are required: the plugin only uses Qt (via qgis.PyQt) and qgis.core/qgis.gui, all of which ship with QGIS.", "homepage": "https://github.com/PardoJean/GranulometriaPorFotointerpretacion", "repository": "https://github.com/PardoJean/GranulometriaPorFotointerpretacion", "tracker": "https://github.com/PardoJean/GranulometriaPorFotointerpretacion/issues", "author": "Jean Pardo", "tags": ["granulometry", "grain size", "particle size", "gradation curve", "sieve", "geotechnics", "soil", "rock", "aggregate", "mining", "quarry", "photointerpretation", "photogrammetry", "drone", "uav", "orthophoto", "segmentation", "image analysis", "raster", "vector", "polygon", "area", "report", "excel", "geopackage", "astm"], "downloads": 341, "latest_version": "1.0.7", "versions": [{"version": "1.0.7", "experimental": false, "qgis_min": "3.22.0", "qgis_max": "3.99.0", "downloads": 101, "uploaded_by": "PardoJean", "upload_datetime": "2026-09-08T18:29:26.062273"}, {"version": "1.0.3", "experimental": false, "qgis_min": "3.22.0", "qgis_max": "3.99.0", "downloads": 87, "uploaded_by": "PardoJean", "upload_datetime": "2026-09-04T15:43:25.428691"}, {"version": "1.0.1", "experimental": true, "qgis_min": "3.0.0", "qgis_max": "3.99.0", "downloads": 153, "uploaded_by": "PardoJean", "upload_datetime": "2026-08-08T13:22:49.976386"}]}
