I'm using MOD09GQ product of MODIS to calculate vegetation indices in Erdas 2014, and I was able to extract NDVI using Erdas Model Builder.
My question is: How can I calculate Land Surface Water index (LSWI), Normalized Difference Water Index (NDWI) and Wide Dynamic Range Water Index (WDRVI) in Erdas? what are the formulas I should use in model builder? Do i need to download another products of MODIS for computing these indices?
