QGIS 4 Arch - Satellite Remote Sensing with Sentinel-2 (SCP, NDVI, Band Combos, Raster Calculator)

Описание

QGIS4Arch is a free online course for learning QGIS, an open source geographic information system (GIS) software package. This course is for those who works with cultural heritage resources, including archaeologists, architectural historians, and historians. The course is designed to take you from beginner to expert. New tutorials uploaded weekly until complete. This video uses QGIS Latest Release version 3.12.

This lessons explores the use of the Semi-Automatic Classification Plugin (SCP) to download satellite imagery, common band combinations, and calculating NDVI. This includes working with the raster calculator.

Updated Sentinel-2 Data Link to Update SCP - https://scihub.copernicus.eu/dhus/

Can't get SCP to download Sentinel-2, go here - https://earthexplorer.usgs.gov/ (it does have a 1-2 week versus the above website, but is a good workaround if needed)
