Geobricks library to correlate two raster and create statistics and scatter charts.

Project description

Geobricks Raster Correlation

The Geobricks Raster Correlation library provides an easy way correlate two raster of the same size, returning a json containing statistical outputs and frequencies information to be used directly with Highcharts JS library.

# Installation

The library is distributed through PyPi and can be installed by typing the following command in the console:
pip install GeobricksRasterCorrelation
# Examples

## Library usage

from geobricks_raster_correlation.core.raster_correlation_core import get_correlation

raster_path1 = "path_to_raster1.tif"
raster_path2 = "path_to_raster2.tif"
# Number of bins to be applied to the scatter chart
bins = 300
corr = get_correlation(raster_path1, raster_path2, bins)
print corr

The returned json contains:

* in corr['stats'] the statistics: slope, p_value, std_err, intercept, r_value
* in corr['series'] there are the series. The series output can be used directly as an input with Highcharts.
