Thanks, Chris.
I am interested in the chlorophyll-a level near Indian coastal districts and Modis aqua has the data for the entire world from 2002. I also have the shape files for indian districts and trying to overlay them on the Modis Aqua raster file, to find the chlorophyll-a content in certain kms from the coastal border. For ex, I would like to draw a circle of 25 km radius from each coastal district and create smaller areas within each circle (as in fishnet) and calculate the chl-a within each smaller area.
I have checked the image analysis toolbar and trying to do some raster analysis. Is there any source you can recommend for me to learn about ocean colour measurement and sea level temperature measurement for the task I explained here, please. Any textbook or some link would be helpful.
Thanks.
