Assessing the Effects and Effectiveness of Conservation Practices Through Advanced Geospatial Techniques
Hydrology and Remote Sensing Laboratory
2013 Annual Report
1a.Objectives (from AD-416):
The objective of this agreement is to develop methods to produce maps of wetlands and key wetland functional drivers and link those maps to ecosystem function.
1b.Approach (from AD-416):
ARS will meet with operational agencies to determine science needs and acquire remotely sensed data. Both parties will jointly determine the best approach for processing remotely sensed data and integrating in situ information. The cooperator will implement the agreed upon approach and both parties will analyze and present study results.
Efforts to refine the satellite calibration for nutrient uptake by winter cover crops continued under this project. This effort involved collection of cover crop samples during the winter and spring periods and related biomass measurements to spectral information in satellite images. Additional effort involved determining the utility of atmospheric corrections for improving calibrations. State wide implementation of satellite monitoring of cover crop performance requires development of software tools for capturing of geospatial data and for data analyses within the geospatial context. Substantial progress was made toward the development and refinement of these tools.
