Data Update
Function Description
Use the contents of One or more raster datasets to update the contents of the corresponding part of another Raster Dataset.
The following figure shows an example of batch Data Update: the left figure shows the Updated Data, namely the Target Dataset, and the middle figure shows a group of multiple Raster Datasets, which are used to update the contents of the corresponding positions of the Target Dataset. The figure on the right shows the result after Data Update.

The data used in the Update Raster Dataset shall meet the following requirements:
- Pixel Format of Target Dataset and Update Data set shall be consistent;
- The ranges of two Raster Datasets overlap. Only the overlapping part can replace the value in the corresponding Target Dataset with the value in the Update Data set.
Function entrance
- Data tab-> Data Processing-> Grid-> Data Update.
- Toolbox-> Data Processing-> Grid-> Data Update.
Parameter Description
- Datasource: Set the Datasource where the Target Dataset is located.
- Dataset: Set the Target Dataset.
- Source Data: The data source part includes the toolbar button and the list box.
- Use the toolbar buttons to add, delete, select, and sort the Source Dataset. The
- list box displays one or more raster Image Datasets to be used to update the Target Dataset, which will be loaded into the Target Dataset as Update Data. Data Update follows the order of multiple records in the list box from bottom to top.
