Examples for a blog series on Geospatial Julia using ArchGDAL. The aim of this series is to have a look at the potential for Julia in Geospatial technology. I am more focused on Raster data, in particular data from Satellites - in these posts I will be using Sentinel 2a data. I will be using the ArchGDAL package for this work. There maybe other packages available, at present (Feb 2019) ArchGDAL offered far more than any other Julia package that I could find. I am more than happy to be corrected though.

Dec 2021 I have updated all the code for Julia 1.7.0. Plus added a new notebook and blog. Enjoy!

Isle_Wight.tif (https://github.com/acgeospatial/Julia_Geospatial/blob/master/Isle_wight.tif) is a sample image to be used in some of these scripts. It is a 10m spatial resolution RGB Sentinel 2a image from 2017 (from May I think). I have preprocessed it. I have performed a 99% clip stretch on the data for better display. This was done in Python using Rasterio, but should be possible in ArchGDAL as well, perhaps using https://juliastats.github.io/StatsBase.jl
