Create image composites can be useful for many applications but it can be difficult to do well and efficiently. The following tutorial shows how to create a maximum NDVI composite for two Landsat row/paths for 2005 and 2010.

This is a tutorial which goes through automating drone flights using the PrecisionFlight app and then processing the resulting imagery using the Precision Mapper service to produce an ortho-mosaic. This PDF for the tutorial can be downloaded from here: DroneCapture_PrecisionFlight_Compress.pdf The resulting orthomosaic from the flight within this tutorial can be viewed from here: https://remotesensing.info/tutorialmaterials/drones/IntroPrecisionFlight/DroneTest1.html Other […]
This tutorial provides an introduction to different methods of change detection for remote sensing image analysis and classification. It also demonstrates comparing a number of machine learning classifiers. Worksheet (RSGISLib_ImgClass_ChangeDetection.pdf) Datasets (RSGISLib_ChangeClassification_Training.zip)
We’ve written a plugin for QGIS which allows the accuracy of classification to be assessed in an efficient manner. For information on how to use the plugin and follow the tutorial in the worksheet below: Worksheet (ClassAccuracyQGISPluginTutorial.pdf) Example Dataset for Worksheet (ClassAccuracyExample.zip) The latest version of the plugin can be download from the bitbucket repository.
The following tutorial provides an introduction to analysis ready data (ARD) and atmospheric correction using ARCSI. The main datasets used for the tutorial are some Landsat 5 scenes, these are smaller in file size and therefore quicker to download. However, Sentinel-2 is also addressed and the modifications to the Landsat 5 commands provided as examples. […]

The tutorial includes: Image band maths Create python command line tools Using the python multi-processing library Per-pixel based image classification Object Base image classification Image segmentation The tutorial using ALOS PALSAR and Landsat Image. The documents can be […]
The MOMENTS project is a Newton fund project administered in the UK by NERC and is focused on understanding changes in mangrove forests. The project is working in Sumatra, Indonesia and the Red River Delta, Vietnam. Within the tropics, mangrove forests are seen as one of the most sustainable solutions to coastal climate adaptation and mitigation […]
