OTB Virtual Workshop

Virtual Workshop: Remote sensing from space and applications

Training material for an introduction to OTB

This repository is a fork of David Youssefi workshop for Malta university (https://gitlab.orfeo-toolbox.org/dyoussef/2020-otb-malta) with some notebooks initially prepared for the "OTB Guided Tour" (https://gitlab.orfeo-toolbox.org/dyoussef/otb-guided-tour). This repository contain different notebooks, designed to be run on Python environment, locally or remote (for instance, with Google Colab or Binder). The wiki pages associatd with this repo contain some slides as well as some datapackages.

Download the 64-bit Linux installation of the Orfeo Toolbox

mkdir -p ~/install && cd ~/install
wget https://www.orfeo-toolbox.org/packages/OTB-7.2.0-Linux64.run

This package is a self-extractable archive. You may uncompress it with a double-click on the file, or from the command line as follows:

chmod +x OTB-7.2.0-Linux64.run
./OTB-7.2.0-Linux64.run
cd OTB-7.2.0-Linux64/
. otbenv.profile
ctest -S share/otb/swig/build_wrapping.cmake -VV

Then, create a vitual environment

python3 -m venv ~/venv_OTB7.0
. ~/venv_OTB7.0/bin/activate
pip install --upgrade pip
export CPATH="~/install/OTB-7.2.0-Linux64/include"
pip install --no-binary rasterio
pip install notebook matplotlib folium Shapely requests geojson
