Calculate Gravity Acceleration Grid
Overview
Calculates gravity acceleration values for raster data and generates a gravity acceleration grid.
How It Works
The tool reads the spatial extent, coordinate system, and cell positions of the input raster, then calculates the gravity acceleration value for each cell based on its latitude. The output keeps the same grid structure as the input raster, and each cell stores the theoretical gravity acceleration at that location.
Use Cases
- Quickly generate standardized results when you need to run the Calculate Gravity Acceleration Grid tool.
- Use the output as an intermediate step in a longer GIS processing chain for subsequent analysis.
- Improve efficiency in batch processing, repeated execution, or standardized delivery workflows.
Parameters
| Parameter | Description | Notes |
|---|---|---|
| Input raster file | The raster file for which gravity acceleration will be calculated. | Required |
| Output gravity acceleration grid file | The output raster file containing the gravity acceleration grid. | Required |
Steps
- Start the tool: Open the Geoprocessing Toolbox, go to Raster Tools > Raster Calculation > Raster Calculation, and open the Calculate Gravity Acceleration Grid tool pane.
- Prepare the input: Select the Input raster file and confirm that the input data is complete and readable.
- Set core parameters: Configure the required parameters according to your workflow. Adjust settings related to units, thresholds, statistics, or interpolation methods when applicable.
- Set the output: Specify the Output gravity acceleration grid file, and confirm that the output path, format, and naming rules meet downstream requirements.
- Run and review the result: Click Run to execute the task. After completion, check whether the result extent, value distribution, field structure, or spatial position is as expected.
Notes
- When calculations involve multiple rasters, first confirm that their coordinate systems, resolutions, extents, and grid alignment are consistent.
