GDAL boots

Python friendly wrapper over GDAL

"When you see someone putting on his Big Boots, you can be pretty sure that an Adventure is going to happen."

A. A. Milne

WARNING

This is early implementation of library, use it for you own risk.

Example

import json
import affine
import numpy as np
from gdal_boots import RasterDataset, GeoInfo, JP2OpenJPEG, GTiff

minsk_polygon = json.load(open('./tests/fixtures/minsk-polygon.geojson'))

img = np.random.randint(
    0, 255,
    size=(1098, 1098),
    dtype=np.uint8)

geoinfo = GeoInfo(
    epsg=32635,
    transform=(
        affine.Affine(10.0, 0.0, 499980.0, 0.0, -10.0, 6000000.0) *
        affine.Affine.scale(10, 10)
    )
)
with RasterDataset.create(img.shape, img.dtype, geoinfo) as ds:
    ds[:,:] = img
    ds[100:350, 100:350] = 128
    ds.to_file('tile.jp2', JP2OpenJPEG(quality=50))

    cropped_ds = ds.crop_by_geometry(minsk_polygon)
    cropped_ds.to_file('minsk.tif', GTiff(tiled=True))
