nyuki.geotiff_resampler module

Console script for src.

nyuki.geotiff_resampler.resample_raster(raster, out_path=None, scale=1)

Resample a raster multiply the pixel size by the scale factor divide the dimensions by the scale factor i.e given a pixel size of 250m, dimensions of (1024, 1024) and a scale of 2, the resampled raster would have an output pixel size of 500m and dimensions of (512, 512) given a pixel size of 250m, dimensions of (1024, 1024) and a scale of 0.5, the resampled raster would have an output pixel size of 125m and dimensions of (2048, 2048) returns a DatasetReader instance from either a filesystem raster or MemoryFile (if out_path is None)

nyuki.nyuki module

nyuki.utilities module

Utilities file for Nyuki package.

These are some miscellaneous helper functions to facilitate some of Nyuki’s operations. The functions include

1. get_file_type(): Function to determine if a file is a vector or raster file.

nyuki.utilities.dhash_distance(left, right, hash_size=8)

nyuki.utilities.get_file_type(filename)

This function will determine whether a file is a raster or vector geospatial file. For example, a Geotiff file is a raster file, while a shapefile or geojson file is a vector file.

nyuki.vector_reprojector module

Console script for geotiff_reprojector.

nyuki.vector_reprojector.vreprojector(sourcefile, target_epsg='EPSG:4326', yes=False)
