Common Statistics
Feature Description
The Common Statistics function performs statistical analysis by comparing input raster data with either a fixed value or one/multiple raster datasets. It supports two comparison modes:
- Compares input raster dataset with corresponding pixel values in one or more raster datasets, counting the frequency of "true" comparison results.
- Compares a raster dataset cell-by-cell with a fixed value using specified operators, assigning 1 to cells with "true" results and 0 to "false" results.
Feature Entry
- Spatial Analysis Tab->Raster Analysis group->Raster Statistics->Common Statistics.
- Toolbox->Raster Analysis->Raster Statistics->Common Statistics.
Parameter Description
- Source Dataset: Select raster data to analyze, including its datasource and dataset.
- Statistical Parameter Settings: Configure parameters based on statistics type.
- When comparing with fixed value: Select comparison operators (equal to, greater than, less than, no less than, no more than). Choose "Fixed Value" radio button and enter value.
- When comparing with raster datasets: Select comparison operators. Choose "Raster Dataset" radio button, then select single/multiple datasets via "Select" button.
- Ignore No Value: Enabled by default. Excludes NoData values from statistics when checked.
- Result Data: Configure output parameters including result datasource and dataset name.
