Custom Map Downloader is a QGIS plugin that allows users to generate high-resolution, georeferenced GeoTIFF images from any loaded map layer. By providing a single latitude–longitude point, desired GSD (ground sampling distance), and output dimensions, the plugin automatically computes the correct map extent, renders the specified layer at the requested resolution, and exports a fully geotagged TIFF file. It supports satellite imagery, XYZ tiles, raster layers, and vector tile layers, making it ideal for simulation, training data generation, offline map extraction, and custom analysis workflows. Features include optional georeferencing toggle, automatic layer loading, progress feedback, and GDAL-based geospatial metadata.
✅ Export Any Layer - Works with satellite imagery, XYZ tiles, raster layers, and vector tile layers
✅ Precise Positioning - Specify center point using latitude/longitude coordinates (EPSG:4326)
✅ Custom Resolution - Configure Ground Sampling Distance (GSD) in meters per pixel
✅ Flexible Dimensions - Set custom output dimensions (width × height in pixels)
✅ Optional Georeferencing - Toggle between georeferenced GeoTIFF or plain TIFF export
✅ Automatic Layer Loading - Optionally load exported image directly into QGIS
✅ Progress Feedback - Visual progress dialog during export
✅ Proper Metadata - Full GDAL georeferencing with EPSG:3857 projection
✅ Optimized Output - LZW compression and tiling for efficient storage
