STEREO toolbox en LUMOS

U bent hier

Tijdens de opeenvolgende STEREO-programma's ontwikkelden de onderzoeksteams een hele reeks beeldverwerkingsalgoritmen. Deze algoritmen zijn toepasbaar op verschillende soorten afbeeldingen en in een heleboel werkvelden

Het LUMOS-project (Remote sensing image processing algorithms for land use and land cover monitoring systems) werd opgezet als onderdeel van het STEREO III-programma / Ontwikkeling van toepassingen, met het specifieke doel om deze algoritmen te promoten en de onderzoeksresultaten van Belgische wetenschappers te valoriseren. 

Het doel is om de algoritmen die werden ontwikkeld tijdens het STEREO II-programma om te zetten in gebruiksvriendelijke plug-ins (geschreven in Python) voor de algemene open-sourceomgeving QGIS.

Ontdek hieronder de tools die al door LUMOS zijn ontwikkeld, evenals een reeks software die parallel met het LUMOS-project is ontwikkeld door de teams van onderzoekers die betrokken zijn bij het STEREO-programma.

Te verwachten producten en diensten

  • Een reeks gebruiksvriendelijke QGIS-plugins, handleidingen, testgegevens en oefeningen;
  • Een standaardprotocol voor toekomstige software ontwikkelaars in het kader van STEREO-programma's;
  • Een specifieke workshop om de STEREO-tools te lanceren en aan gebruikers te demonstreren. 

Potentiële gebruikers

De tools worden zó geschreven dat ze drie types gebruikers van dienst kunnen zijn:

  1. Thematische gebruikers: gebruiksvriendelijke GUI met standaardinstellingen;
  2. Gespecialiseerde gebruikers: gebruiksvriendelijke GUI met (gespecialiseerde) opties;
  3. Ontwikkelaars: duidelijk gedocumenteerde tweakcodes.

LUMOS AVAILABLE TOOLS

MESMA in QGIS

 

MESMA is both a QGIS plugin and stand-alone python package that implements the MESMA (Multiple Endmember Spectral Mixture Analysis) unmixing algorithm in the field of Remote Sensing.

It is based on VIPER Tools: a software package written for ENVI/IDL and released in 2007. Several updates have been released since and now it has been ported to PyQGIS in the period 2017 - 2020. The original VIPER Tools is now split over two python/QGIS tools: Spectral Library Tool and MESMA.

Spectral Library Tool

 

The Spectral Library Tool software package is both a QGIS plugin and stand-alone python package that provides a suite of processing tools for multi- and hyperspectral spectral libraries.

The software is based on VIPER Tools: code written for ENVI/IDL and released in 2007. Several updates have been released since and now it has been ported to PyQGIS in the period 2017 - 2020. The original VIPER Tools is now split over two python/QGIS tools: Spectral Library Tools and MESMA.

 

Tree Density Calculator

 

The Tree Density Calculator is a QGIS plugin and command line interface package designed to calculate tree densities based on brightness images, using the local maximum of a sliding window.

The original Tree Density Calculator was written in C++ and ported to PyQGIS in 2018/2019. It has been developed in an open source environment to encourage further development of the tool.

Neural Network MLPClassifier

 

The Neural Network MLPClassifier software package is both a QGIS plugin and stand-alone python package that provides a supervised classification method for multi-band passive optical remote sensing data. It uses an MLP (Multi-Layer Perception) Neural Network Classifier and is based on the Neural Network MLPClassifier by scikit-learn.

The program was originally developed by Lieven P.C. Verbeke (Ghent University, Laboratory of Forest Management and Spatial Information Techniques). It was written in C++ and ported to PyQGIS in 2019 - 2020. It has been developed in an open source environment to encourage further development of the tool.

    OTHER STEREO AVAILABLE TOOLS

    Onderzoeksteams betrokken bij het STEREO-programma hebben ook software ter beschikking gesteld buiten het LUMOS-project. Hieronder een selectie.

    Complete InSAR suite developed by the signal Lab of CSL

     

    The Centre Spatial de Liege (CSL) has a long standing experience in the frame of SAR processing and SAR interferometry (InSAR). In the frame of numerous projects mainly funded by BELSPO and ESA, the signal Lab of CSL has developed a complete InSAR suite now known has CIS. CIS, as all tools of its kind, allows performing all processing steps for InSAR, DInSAR, PolSAR, PolInSAR, … including geoprojection of results in raw or ENVI format.

    DIARS toolbox

     

    This website is part of the DIARS project that brings together European experts from remote sensing and ecology to demonstrate and characterize the impact of invasive species on ecosystems through the combined use of field data and data obtained through remote-sensing technologies and support the monitoring and prediction of spread and risk assessment of invasive plant species. It consists of a series of tutorials that walk you through a remote sensing-based framework for mapping, modelling and assessing the impact of biological invasions.

    SAT-EX Codes & Data

     

    The SAT-EX project focused on tne impact of climate and climate extremes on global vegetation. Different source codes are freely available via the Laboratory of Hydrology and Water Management (LHWM) github channel:

    • ConditionalSpectralGrangerCausality

    • E2CI---Detecting-relations-between-modes-of-climate-variability-and-land-evaporation

    • Hydro-climatic-biomes

    • ClimateVegetationDynamics_GrangerCausality

    TACT

     

    TACT is the Thermal Atmospheric Correction Tool for Landsat developed at RBINS. It retrieves ERA5 atmospheric profiles and uses libRadtran to compute the atmospheric transmittance, and down- and upwelling radiances. Currently TACT outputs the Water Surface Temperature (WST) in each thermal band present on the Landsat sensor, assuming a constant (water) emissivity over the scene.

    TREX  

    TREX (Tool for Raster data EXploration) is an automatic processing tool allowing extraction of Time series of Leaf Area Index from ProbaV satellite images.

    TREX was developped for the STEREO III HIWET (High-resolution modelling and monitoring of water and energy transfers in wetland ecosystems) project and is  available on GITHUB.
