Hi GeoClubSS, For land use/land cover (LULC) change detection, the number of bands required can vary depending on several factors such as the spatial resolution of the imagery, the complexity of the landscape, and the specific algorithms or techniques being used. However, commonly used satellite data like Landsat typically provide multispectral imagery with several bands. For basic LULC change detection, you can start with using bands such as near-infrared (NIR), red, green, and blue. These bands are often sufficient for detecting changes in vegetation, urban areas, and other land cover types. Additionally, incorporating bands like thermal infrared or shortwave infrared can provide additional information for certain applications. Ultimately, it's essential to consider the specific requirements of your study area and the objectives of your analysis when determining the number and types of bands to use.
Hi you can download those bands (Landsat 8 satellite image) from EarthExplorer website. Please check my video on downloading landsat 8 images: ua-cam.com/video/UuE8tFYz6q0/v-deo.html
For LULC change detection, how many bands are required? kindly help
