I have 12 MODIS images (one of each month). I want to create a single image having maximum annual pixel values for each pixel. I did layer stacking operation in Erdas Imagine 13, but how to extract the maximum pixel value ?
You can also complete this analysis using ArcGIS or QGIS. If you are using indices derived from MODIS, just add them into the queue. Otherwise, you will need to separate the MODIS bands prior to adding them to the queue.
