如何查看 GEOTIFF、COG、TIFF 文件
GeoTIFF stores georeferencing with raster pixels, while COG optimizes tiled range access. Use this tool for inspection, not QGIS reprojection or raster analysis.
- Choose a .tif or .tiff file.
- Review dimensions, band count, geographic bounds, resolution, and NoData.
- Select RGB bands or a single-band color ramp.
- Read pixel values under the pointer and check orientation, stretch, and gaps.
Wobei es hilft
- Distinguish ordinary TIFF from geospatial raster
- Quick band and geotag inspection
- The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
Kompatibilität und Einschränkungen
- Not every EPSG definition is resolved and no reprojection is performed
- Huge non-COG files can consume substantial memory
- Display stretching is a preview, not quantitative remote-sensing analysis
Häufig gestellte Fragen
Can it open a normal TIFF?
It may display pixels, but reliable map bounds are unavailable without geotags.
Why is the image black?
16/32-bit data often needs a display stretch; choose the intended band and adjust min/max.
Is the raster uploaded?
The file is parsed inside this browser tab and is not uploaded to FreeTool to use the tool.
