How to distinguish between swamps/marshes from cropland and grassland with using LANDSAT-8 data? Is there any index to find out only swampy or marshy lands?
Can I calculate it in any one of the following platform : ArcMAP/ERDAS IMAGINE/R/ MATLAB/PYTHON environment please also mention.
Or
Do high resolution open source global land cover data available online that has swamps/marshes as one of the land cover class?
For indices calculation as far as I know you can use all of them but the three first are the one I'm certainly sure.
You can find in this link some of the most popular indices out there right now. You could start using NDVI or NDWI to tackle your problem.

I hope this will help you
I am in agreement with Ivan. NWDI may be useful in solving your problem.
dear you can visit RG for me , so I thank written for this subject and meet you
I am working on similar task. You can use machine learning classifier， terrain data (DEM, and its derived terrain indices )and multi spceral indices (NDVI, NDWI, NDWI, MNDWI, EVI...) to detect swamps/marshes.
Hi, Jingzhe Wang. Can you please share some documents, tutorials or research papers that explain details of this aspect? Mainly the flow chart of the process.
