Display/Edit MetadataΒΆ

This module allows for the display and custom editing of metadata associated with raster images. It is especially useful for defining nodata values or band names.

  1. Band Name - Shows the current name of a raster band within the dataset. Change to a different band by using the drop-down menu.

  2. Rename Band Name allows the user to change the name of the currently selected band.

  3. The Dataset section shows physical information about the dataset.

  • Top Left X-Coordinate: Raster X coordinate in the NW corner of the dataset.

  • Top Left Y-Coordinate: Raster Y coordinate in the NW corner of the dataset.

  • X-Dimension: width of a grid cell (in the x-direction).

  • Y-Dimension: height of a grid cell (in the y-direction).

  • Null/Nodata Value: A unique value assigned to areas of the dataset with no data.

  • Rows: Number of rows in the dataset.

  • Columns: Number of columns in the dataset.

  • Dataset minimum: Minimum Z value in the dataset.

  • Dataset maximum: Maximum Z value in the dataset.

  • Dataset mean: Mean Z value in the dataset.

  • Dataset units: A label used in graphs to denote the units of the data in the currently selected band.

  • Data type: The data type such as float32, float64, integer etc.

  • Acquisition Date: Data collection date of the currently selected band

  1. Input Projection: Current projection assigned to the raster band. It can be reassigned, but note that this does not reproject the data.
