Resample/Warp (Reproject)

org.knime.geospatial version 1.0.2 by OSA

This node takes a list of raster file location in the input table, perform the warping using gdalwarp command and generate a list of output rasters in the desired location. The output table contains the generated raster file locations.

Options

Resample method
Resampling method to use. the default value is "average"". Check here for details
Working memory
Set the amount of memory (in megabytes) that the warp API is allowed to use for caching. By default it is set to 500 MB
Source Spatial Reference Set
Source spatial reference set. The coordinate systems that can be passed are anything supported by the OGRSpatialReference.SetFromUserInput() call, which includes EPSG PCS and GCSes (i.e. EPSG:4296), PROJ.4 declarations (as above), or the name of a .prj file containing well known text. It is optional and can be empty.
Target Spatial Reference Set
Target spatial reference set. The coordinate systems that can be passed are anything supported by the OGRSpatialReference.SetFromUserInput() call, which includes EPSG PCS and GCSes (i.e. EPSG:4296), PROJ.4 declarations (as above), or the name of a .prj file containing well known text. It is optional and can be empty.
Output File Resolution (X and Y)
Set output file resolution (X and Y) (in target georeferenced units). Both must be positive values.
Output format
Select the output format. The default is GeoTIFF (GTiff)
Target Aligned Pixels
Target aligned pixels. Check this box if you want to align the coordinates of the extent of the output file to the values of the output file resolution, such that the aligned extent includes the minimum extent.
Overwrite
Check this box if you want to overwrite the target dataset if it already exists.
Output Folder Location
Location of the output folder where your new raster files will be generated. It will also generate a text file "commands.txt" in this location that contains all the commands use for generating raster. The commands in this file can be run separately as a batch file.
File Naming
There are two file naming convention here. If the first option "Use name of source file" is selected then it will generate output the raster files with the same name of source raster file in the input table. This selection will ignore the value in "Select input column" option. If the second option "Sub-directory based on column" is selected then it will generate output the raster files according to the values in selected column in ""Select input column" option. By default it is set to "Use name of source file".
Select input column
This works along with "File Naming" option
Run commands
Check this option if you actually want to run the gdal commands. You have option to run it from the generated "commands.txt" file as a batch script if you decide not to run it. By default it is checked.

Input Ports

Icon
The locations of source raster files. The table must contain a "Location" column.

Output Ports

Icon
The locations of generated raster file. It uses "Location" as column header.
