FauxGeo: generate simple geospatial rasters

FauxGeo is a python library that generates simple OSGeo-supported rasters. The primary purpose for this library is to help test geoprocessing functions.

Features

Available Signal Functions

Signal Function	RasterFactory Method
uniform	.uniform(val)
ramp	.ramp(zero_index, slope=1)
saw tooth	.saw(low, high, period)
triangle	.triangle(low, high, period)
step	.step(low, high, period)
random range	.random(low, high)
random from list	.random(list)
alternating	.alternate(val1, val2)

Installation

To install FauxGeo, simply:

$ pip install fauxgeo

Usage

import numpy as np
from fauxgeo import RasterFactory, Affine

options = {
  'affine': Affine.identity(),
  'epsg': 4326,
  'datatype': np.float32,
  'nodata': -9999,
  'driver': 'GTIFF',
  'shape': (10, 10)
}

factory = RasterFactory(**options)
factory.uniform(5).to_file('path/to/file')
