COG (Cloud Optimized GeoTIFF) ni kiendelezi cha GeoTIFF kwa huduma za wingu. Kwa kazi za eneo lako, GeoTIFF ya kawaida ni bora zaidi.

GeoTIFF (Georeferenced TIFF)

Open Beta

.tif · image/tiff

GeoTIFF ni umbizo la rasta lenye urejeleaji wa kijiografia uliojengwa ndani. Ramani huhifadhiwa kama picha ya TIFF yenye viratibu, mradio, na metadata. Kiwango halisi cha ramani za rasta zenye urejeleaji wa kijiografia.

Vipengele Muhimu

✓Viratibu vilivyojengwa ndani (WGS84 / UTM)

✓Usaidizi wa mradio

✓Mwonekano wa juu kwa uchapishaji

✓Uoanifu wa kawaida wa GIS

Kuhusu Muundo wa GeoTIFF

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.

Nani Hutumia Ramani za GeoTIFF

🏗

Ramani zenye urejeleaji wa kijiografia

A picture of the map that puts itself in the right place in any GIS.

💻

Uchanganuzi wa GIS

A raster underlay beneath your own vector layers and calculations.

📊

Uwekeleaji wa picha za satelaiti

The map lands over the image in the same coordinates — you can see at once what changed and where.

🎨

Utambuzi wa mbali

Material for interpretation and comparison with survey data.

🗺

Uchapishaji wa ramani

300 DPI — ready print quality for a poster or a report appendix.

Jinsi ya Kufungua Baada ya Kuhamisha

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.
