Remote Sensing Data
YERC employs a range of remote sensing data and analysis methods to optimize the retrieval of biophysical parameters that support ecological research. We utilize airborne and spaceborne platforms, optical and microwave wavelengths as well as passive and active sensors. From high resolution photography to shuttle based radar data, YERC takes advantage of the strengths of different datasets and has the experience to exploit
YERC possesses a wealth of remote sensing data over the Yellowstone Ecosystem including multispectral and hyperspectral data, lidar, and Synthetic Aperture Radar (SAR). Below are some examples of the data that YERC scientists are using:
| Image |
Data Type |
Sensors/Use |
|
Hyper-spectral
Data |
Hyperpsectral data from AVIRIS, HyMap, Probe1 and hyperion sensors provide over 100 spectral channels to describe biophysical parameters |
|
|
Multi-spectral
Data |
Multispectral data from Landsat (MSS, TM, ETM+), ASTER and MODIS provide large scale repeat coverage at the landscape scale |
|
|
High-res Airborne Imagery |
Airborne from ADAR and color infra red photography provide detailed sub-meter imagery for fine-scale analysis |
|
|
Synthetic Aperture Radar (SAR) |
Polarimetric SAR data from AIRSAR, SIR-C and JERS provide information on vegetation type and structure as well as soil moisture |
|
|
Lidar |
LIDAR data provide detailed measurements of vegetation height and a source for DEMs |
|
|
Digital Elevation Models (DEMs) |
DEMs from Star3i, SRTM and lidar provide detailed descriptions of topography and play a critical role in modeling ecological processes and for assisting in the analysis of other remote sensing data layers |
