A collection of fancy functional tools focused on practicality

A collection of fancy functional tools focused on practicality. Inspired by clojure, underscore and my own abstractions. Keep reading to get an overview or read the docs. Or jump directly to cheatsheet. Works with Python 2.7, 3.4+ and pypy. Installation pip install funcy Overview Import stuff from funcy to make things happen: from funcy import whatever, you, need Merge collections of same type (works for dicts, sets, lists, tuples, iterators and even strings): merge(coll1, coll2, coll3, …) join(colls) merge_with(sum, dict1, […]

The whitebox Python package is built on WhiteboxTools

whitebox-python The whitebox Python package is built on WhiteboxTools, an advanced geospatial data analysis platform developed by Prof. John Lindsay (webpage; jblindsay) at the University of Guelph’s Geomorphometry and Hydrogeomatics Research Group. WhiteboxTools can be used to perform common geographical information systems (GIS) analysis operations, such as cost-distance analysis, distance buffering, and raster reclassification. Remote sensing and image processing tasks include image enhancement (e.g. panchromatic sharpening, contrast adjustments), image mosaicing, numerous filtering operations, simple classification (k-means), and common image transformations.

Get Landsat surface reflectance time-series from google earth engine

Google Earth Engine data extraction tool. Quickly obtain Landsat multispectral time-series for exploratory analysis and algorithm testing Online documentation available at https://loicdtx.github.io/landsat-extract-gee A python library (API + command lines) to extract Landsat time-series from the Google Earth Engine platform. Can query single pixels or spatially aggregated values over polygons. When used via the command line, extracted time-series are written to a sqlite database. The idea is to provide quick access to Landsat time-series for exploratory analysis or algorithm testing. Instead […]
