In-Depth Information
These values are adjusted by the burn value given by “-burn value” or “-a
attribute_name” if provided. As of now, only points and lines are drawn in 3D.
-l layername
Indicates the layer(s) from the datasource that will be used for input features.
May be specified multiple times, but at least one layer name or a -sql option must
be specified.
-where expression
An optional SQL WHERE style query expression to be applied to select features
to burn in from the input layer(s).
-sql select_statement
An SQL statement to be evaluated against the datasource to produce a virtual
layer of features to be burned in.
-of format
(from GDAL 1.8.0) Select the output format. The default is GeoTIFF (GTiff).
Use the short format name.
-a_nodata value
(from GDAL 1.8.0) Assign a specified no-data value to output bands.
-init value
(from GDAL 1.8.0) Pre-initialize the output image bands with these values.
However, it is not marked as the no-data value in the output file. If only one value
is given, the same value is used in all the bands.
-a_srs srs_def
(from GDAL 1.8.0) Override the projection for the output file. If not specified,
the projection of the input vector file will be used if available. If incompatible
projections between input and output files, no attempt will be made to reproject
features. The srs_def may be any of the usual GDAL/OGR forms, complete
WKT, PROJ.4, EPSG:n or a file containing the WKT.
-co "NAME=VALUE"
(from GDAL 1.8.0) Passes a creation option to the output format driver. Multiple
-co options may be listed. See format specific documentation for legal creation
options for each format.
-te xmin ymin xmax ymax
(from GDAL 1.8.0) set georeferenced extents. The values must be expressed
in georeferenced units. If not specified, the extent of the output file will be the
extent of the vector layers.
-tr xres yres
(from GDAL 1.8.0) set target resolution. The values must be expressed in geo-
referenced units. Both must be positive values.
-tap
(from GDAL 1.8.0) (target aligned pixels) align the coordinates of the extent of
the output file to the values of the -tr, such that the aligned extent includes the
minimum extent.
