GeoTIFF 형식 소개

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.

완성된 GeoTIFF 파일을 다운로드하여 QGIS에서 여세요

내보낸 뒤 여는 방법

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.
