关于 GeoTIFF 格式
GeoTIFF is an ordinary TIFF with coordinates written into its tags: where the top left corner lies, what the pixel size is and which coordinate system all of it is recorded in. A GIS program opens such a file and immediately puts the picture in its place on the ground — there is nothing to georeference by hand.
A raster map is needed where vectors are excessive or awkward: an underlay beneath your own layers, a print-ready original, an overlay on a satellite image, material for interpretation and for raster algorithms.
The file contains a map page drawn in the chosen style and saved as a georeferenced image. The default resolution is 300 DPI, that is print quality; the default sheet is A4 landscape. LZW compression is lossless, yet noticeably smaller than an uncompressed TIFF.
The default coordinate system is WGS84 (EPSG:4326); the georeferencing sits in the file's own tags, so there is no need to keep any companion files alongside it.

格式规格
- 开放标准
- 仅 2D
- 无损(无质量损失)

- GeoTIFF (OGC) with georeferencing tags. Single .tif file; default LZW compression. Standard for GIS raster.
谁在使用 GeoTIFF 地图
如何导出 GeoTIFF
导出后如何打开
- QGIS (free) — drag the .tif into the program window: the layer lands in place and the projection is detected automatically.
- ArcGIS and Global Mapper — Add Data; the raster attaches as an underlay beneath your vector layers.
- Google Earth Pro — File → Import, choose the GeoTIFF: the map lands on the globe (for heavy files the program will offer to reduce the resolution).
- GDAL — gdalinfo map.tif shows the georeferencing and the projection, and gdalwarp -t_srs EPSG:3857 map.tif out.tif reprojects the raster for a web map.
- Printing — the file is calculated for 300 DPI and goes to print as is; in Photoshop or GIMP do not change the pixel dimensions, otherwise you will lose both quality and the match to the scale.
