Purpose: This short tutorial focuses on understanding how to query and download the data from the Goddard Earth Sciences Data and Information Services Center (GES DISC). Since GES DISC consists of 32 projects and missions, we will look into one of the commonly used data – The Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG … CONTINUE READING
GDAL is a powerful geospatial processing library that backups many of the geospatial software you are using. The full list can be found here.
In this post, we will look at a very basic example of reading the raster file including all the bands and looping through the bands to get the statistics (Minimum, … CONTINUE READING
Satellite remote sensing plays an important role in the monitoring of surface water for historical analysis and near-real-time applications. Due to its cloud penetrating capability, many studies have focused on providing efficient and high-quality methods for surface water mapping using Synthetic Aperture Radar (SAR). However, few studies have explored the effects of SAR pre-processing steps … CONTINUE READING
In this tutorial, we will use the MODIS based V6 Terra Vegetation Indices 16-Day Global 250m product. This MODIS NDVI and EVI products are computed from atmospherically corrected bi-directional surface reflectances that have been masked for water, clouds, heavy aerosols, and cloud shadows. We will use this product to create NDVI based threshold classified thematic … CONTINUE READING
Understanding land cover change dynamics and potential pathways of change is of critical importance for sustainable resource management, to promote food security and resilience on a range of spatial scales. Data scarcity is a key concern, however, with the availability of free Earth Observation (EO) data, such challenges can be suitably addressed. In this research, … CONTINUE READING
