Research question

Where are the hottest surfaces in the urban core, and how do they relate to canopy and impervious cover?

Objective

Derive land-surface temperature from thermal bands and relate it to land cover and tree canopy.

Data
Landsat thermal bandssource ↗NLCD canopy & impervioussource ↗
Methodology / Workflow
  1. 1

    Converted thermal DN to brightness temperature and corrected for emissivity.

  2. 2

    Aligned LST with canopy and impervious-surface layers.

  3. 3

    Summarized temperature by land-cover class.
