Class: GeoTIFFSource

ol/source/GeoTIFF~GeoTIFFSource 


import GeoTIFFSource from 'ol/source/GeoTIFF';

A source for working with GeoTIFF data.

new GeoTIFFSource(options)

source/GeoTIFF.js, line 157
Name Type Description
options

Data tile options.

Name Type Description
sources Array.<module:ol/source/GeoTIFF~SourceInfo>

List of information about GeoTIFF sources. Multiple sources can be combined when their resolution sets are equal after applying a scale. The list of sources defines a mapping between input bands as they are read from each GeoTIFF, and the output bands that are provided by data tiles. To control which bands to read from each GeoTIFF, use the bands property. If, for example, you spedify two sources, one with 3 bands and nodata configured, and another with 1 band, the resulting data tiles will have 5 bands: 3 from the first source, 1 alpha band from the first source, and 1 band from the second source.
