Dear All,
Am trying to derive the land surface temperature of an area within the tropix in a bid to detect Urban Heat Island. Am proposing a time series to detect if at all it is existing. My biggest problem lies with deriving of the emissitivity where i have used formulars that have been advanced before but cant get values within the range, Anyone with a clear tutorial on how to derive LST using Envi or Erdas will be very helpful.
Thank you in advance and Regards to all.
