Summary
Spectra are shown for dominant Everglades marshland covers of sawgrass ( Cladium jamaicense) and periphyton as well as common woody plants that boarder Everglades marshlands: willow ( Salix carliniana) and buttonbush ( Cephalanthus occidentalis). Three worksheets are provided in the file. The first (named Graphics) shows the data in line chart form. The second (ASD) shows the spectra in tabular form as collected by the instrument with values in nanometer regions 1800-1962 and 2400-2500 filtered out to reduce noise caused by atmospheric conditions. The third (TM5) contains the spectra as resampled to Landsat Thematic Mapper 5 bands to simulate what would be recorded by Landsat for those land covers. Two tables (nanometers and micrometers) [...]
Summary
Spectra are shown for dominant Everglades marshland covers of sawgrass (
Cladium jamaicense) and periphyton as well as common woody plants that boarder Everglades marshlands: willow (
Salix carliniana) and buttonbush (
Cephalanthus occidentalis).
Three worksheets are provided in the file. The first (named Graphics) shows the data in line chart form. The second (ASD) shows the spectra in tabular form as collected by the instrument with values in nanometer regions 1800-1962 and 2400-2500 filtered out to reduce noise caused by atmospheric conditions. The third (TM5) contains the spectra as resampled to Landsat Thematic Mapper 5 bands to simulate what would be recorded by Landsat for those land covers. Two tables (nanometers and micrometers) are provided. Also, the Modified Normalized Difference Index value for each specta is also provided in the TM5 worksheet.
These spectra were originally collected for a variety of work related to Greater Everglades restoration science. However, this particular subset was used to parameterize an algorithm designed to detect inundated areas in the Everglades using Landsat calibrated surface reflectance products. At the time of publication this algorithm is one of many candidate algorithms for Dynamic Surface Water Extent Landsat Science Product development. The details regarding that use of these spectra are provided in the citation above.
