Reproject Raster Data
Overview
Reproject Raster Data in IXGIS lets you transform raster datasets online to a target coordinate reference system in a browser-based GIS workflow.
Reprojects Input raster file to a target coordinate system and outputs a new raster result.
Use Cases
- Standardize raster data to the project coordinate system before overlay or raster calculation.
- Use the result as an intermediate step in a longer GIS processing workflow.
- Improve consistency in batch processing, repeated tasks, or standardized delivery scenarios.
Parameters
| Parameter | Description | Notes |
|---|---|---|
| Input raster file | Specifies the input raster file. | Required |
| Target coordinate system | Target coordinate reference system, using an EPSG code or WKT string. | Required |
| Resampling method | Resampling method used during reprojection. | Required; default: nearest; options include nearest neighbor (nearest), bilinear (bilinear), cubic (cubic), cubic spline (cubic_spline), Lanczos (lanczos), average (average), mode (mode), Gaussian (gauss), and others. |
| Output raster file | Specifies the output raster file. | Required |
Steps
- Start the tool: Open Geoprocessing Toolbox > Data Management Tools > Projection, then start Reproject Raster Data.
- Prepare the input: Select Input raster file and confirm that the input data is complete and readable.
- Set core parameters: Set Target coordinate system and choose a suitable Resampling method. Use nearest neighbor for classified rasters and bilinear or cubic methods for continuous rasters when appropriate.
- Set the output: Specify Output raster file, and confirm that the output path, format, and naming rule meet downstream requirements.
- Run and inspect the result: Click Run. After completion, check the output extent, cell size, coordinate system, and value distribution.
Notes
- For multi-raster calculations, first confirm that coordinate system, resolution, extent, and grid alignment are consistent.
