GDAL Virtual Raster (beta)

Open Betabeta

.vrt.zip · application/zip

VRT हे रास्टर डेटासेटचे GDAL चे XML वर्णन आहे. आम्ही VRT रेंडर केलेल्या GeoTIFF सोबत एकाच ZIP मध्ये पॅक करतो (map.vrt.zip) — अन्यथा gdalinfo/gdal_translate "map.tif not found" सह अपयशी ठरतात. बीटा: सध्या ओव्हरव्ह्यूशिवाय एकल बँड-संच.

Beta: बीटा -- प्रायोगिक. सेवेला मूळ DWG तयार करता आला नाही, तर ती प्रामाणिकपणे X-Actual-Format: dxf हेडरसह DXF फाइल परत देते (दोन्ही त्याच CAD अनुप्रयोगांत उघडतात).

VRT स्वरूपाबद्दल

VRT is a service format of GDAL: an XML file that contains no pixels but describes where they lie and how to read them. That is the usual way to stitch mosaics and redefine referencing without copying gigabytes of raster.

We hand over the VRT together with the raster itself: the map.vrt.zip archive holds the XML description and the rendered map as a GeoTIFF. That was done deliberately — a lone .vrt would refer to a file you do not have, and gdalinfo simply would not open it.

The XML records the WGS84 coordinate system, the georeferencing (corner coordinates and pixel size) and three RGB bands, each pointing at the corresponding band of the GeoTIFF. The format is in beta status: it is one set of bands with no overview pyramids, and the raster itself is a flattened picture of the map rather than vector layers.

निर्यातीनंतर कसे उघडावे

Unpacking is a mandatory first step: map.vrt and map.tif must lie next to each other in the same folder, since the reference inside the XML is relative.
GDAL — gdalinfo map.vrt will show the size, the referencing and the bands; gdal_translate will convert the set into GeoTIFF, PNG or COG.
QGIS — Layer → Add Raster Layer and pick map.vrt; the layer will land in its place by coordinates.
A mosaic — your own .vrt over several rasters is assembled with gdalbuildvrt out.vrt tile1.tif tile2.tif, if the map has to be stitched with other data.
Editing by hand — VRT is plain XML: the path to the raster, the referencing and the band descriptions can be fixed in a text editor.
