The competent authority of the regulations is the Agency of Rural Development and Soil and Water Conservation, Ministry of Agriculture (ARDSWC, MOA; \u8fb2\u696d\u90e8\u8fb2\u6751\u767c\u5c55\u53ca\u6c34\u571f\u4fdd\u6301\u7f72). This plugin is an independent tool and is not an official product of ARDSWC. Draw a rectangular analysis frame on the map (move / rotate / resize it interactively), choose a 10 m or 25 m cell, and the plugin fills the frame with square cells starting from the top-left corner, counts intersections between each cell edge and the contour lines, and computes the mean slope S = n\u03c0\u0394h/(8L)\u00d7100 and inclination \u03b8 for every cell. Slope grades 1\u20137 (Art. 23) and cell aspect (Art. 26) are written to attribute fields, and an aspect map (8-direction downslope arrows) is produced. When a plan boundary is given, the frame is kept large enough to contain it and only cells overlapping the boundary are generated. Terrain input can be contour lines or a DEM (contours are generated automatically). The plugin styles and labels the results like a conventional hand-drawn grid slope map, builds print layouts for the slope map and the aspect map (legend, north arrow, scale bar, statistics table, notes, signature box), and saves the whole project into an output folder as a new .qgz project file plus a GeoPackage holding all data. \u4f9d\u6c34\u571f\u4fdd\u6301\u6280\u8853\u898f\u7bc4\uff08\u4e3b\u7ba1\u6a5f\u95dc\uff1a\u8fb2\u696d\u90e8\u8fb2\u6751\u767c\u5c55\u53ca\u6c34\u571f\u4fdd\u6301\u7f72\uff09\u5775\u584a\u6cd5\u8a08\u7b97\u5761\u5ea6\u3001\u5206\u7d1a\u3001\u5761\u5411\u4e26\u81ea\u52d5\u7522\u88fd\u5775\u584a\u5716\u3001\u7248\u9762\u8207 GeoPackage \u5c08\u6848\u3002", "homepage": "https://github.com/yoshihuang/swc_grid_slope", "repository": "https://github.com/yoshihuang/swc_grid_slope", "tracker": "https://github.com/yoshihuang/swc_grid_slope/issues", "author": "\u9ec3\u654f\u90ce (Min-Lang Huang)", "tags": ["slope", "grid", "soil and water conservation", "taiwan", "contour", "dem", "\u6c34\u571f\u4fdd\u6301", "\u5775\u584a", "\u5761\u5ea6"], "downloads": 50, "latest_version": "1.2.4", "versions": [{"version": "1.2.4", "experimental": false, "qgis_min": "3.22.0", "qgis_max": "4.99.0", "downloads": 50, "uploaded_by": "yoshihuang", "upload_datetime": "2026-10-31T01:24:23.373780"}]}
