Use when planning a spatial analysis workflow, choosing between analysis approaches, or chaining multiple operations. Prevents wrong analysis method selection and suboptimal workflow ordering. Covers vector vs raster decision trees, processing algorithm…
Use when generating complete maps from data: loading, styling, composing layouts, and exporting. Prevents poor cartographic choices and empty map exports. Covers the full map pipeline: data loading, symbology selection, labeling, layout composition, atlas…
Use when creating QGIS projects, understanding PyQGIS architecture, or reasoning about the QGIS data model. Prevents mixing standalone script initialization with plugin context, and threading violations. Covers Qt-based architecture, 5 core modules, project…
Use when handling coordinate reference systems, transforming coordinates, or measuring distances/areas. Prevents silent data corruption from wrong CRS assignment and lat/lon coordinate order confusion. Covers CRS creation, coordinate transforms, datum…
Use when loading data into QGIS, constructing layer URIs, or choosing between data formats. Prevents URI format errors that cause silent layer loading failures. Covers 12+ data providers, URI construction patterns, vector/raster/mesh formats, and GeoPackage…
Use when diagnosing data loading failures, invalid layers, or provider connection errors. Prevents silent failures from unchecked layer validity and incorrect URI formats. Covers invalid layer detection, URI format errors, encoding issues, GeoPackage locking,…
Use when diagnosing CRS/projection errors, coordinate mismatches, or datum transformation issues. Prevents silent data corruption from wrong CRS assignment and coordinate order confusion. Covers wrong EPSG selection, lat/lon vs lon/lat, datum warnings,…
Use when creating 3D map views, configuring terrain, or rendering vector/point cloud data in 3D. Prevents performance issues from unoptimized point cloud rendering and incorrect terrain configuration. Covers Qgs3DMapSettings, terrain providers, 3D symbols,…
Use when georeferencing raster images or vector data using ground control points. Prevents accuracy loss from insufficient GCPs and wrong transformation type selection. Covers GCP management, 7 transformation types, QgsVectorWarper, residual computation, and…
Use when performing routing, shortest path, or service area analysis on road/transport networks. Prevents incorrect results from wrong edge direction assumptions and missing cost strategies. Covers QgsGraphBuilder, QgsGraphAnalyzer (Dijkstra),…
