Frequently Asked Questions

Q: What mesh formats does uraster support?

A: uraster supports various unstructured mesh formats including:

• GeoJSON

• Shapefile

• MPAS NetCDF meshes

• DGGS (Discrete Global Grid System) meshes

• TIN (Triangulated Irregular Network) meshes

Q: What raster formats are supported?

A: uraster leverages GDAL, so it supports all GDAL-compatible raster formats including:

• GeoTIFF

• NetCDF

• HDF5

• ESRI ASCII Grid

• And many others

Q: How does uraster handle coordinate system differences?

A: uraster automatically reprojects data as needed using GDAL’s projection capabilities. It ensures that raster and mesh data are in compatible coordinate systems before processing.

Q: Can I use custom statistical functions?

A: Currently, uraster provides standard zonal statistics (mean, sum, min, max, etc.). Custom functions may be supported in future versions.

Q: Is uraster suitable for large datasets?

A: Yes, uraster is designed to handle large-scale datasets efficiently. It uses chunking and memory management techniques for processing large raster files.
