|Title||Pasture monitoring using TeraSAR-X|
|Investigator||Pairman, David - Landcare Research, Rural Land Use|
Close monitoring of pasture cover, coupled with climate and weather information for prediction of pasture growth, can provide significant improvements in the efficiency of pasture utilisation by cows, sheep and cattle and also other pasture-based agricultural applications. The CSIRO (Australia) has developed a “Pastures from Space” application for annual pastures of Western Australia, based on MODIS which monitors and predicts pasture growth on a two-weekly basis. Currently the technology is being trialled in Waikato, New Zealand, using SPOT-4 and -5 data.
In New Zealand, persistent cloud cover is very likely to limit optical remote sensing for this application. Our proposal aims to gain an understanding of whether SAR data is sensitive to pasture biomass, the impact of co-factors such as moisture, and the practical implications of using SAR for this purpose.
If successful, TerraSAR-X data could find a market supplementing, or complementing, optical imagery, especially in cloudy regions or in seasons when optical imagery can not be reliably obtained.
To test this application, we wish to analyse 18 datasets over a 12-month period, comparing the TerraSAR-X-derived biomass with ground-based sampling. Promising results would be followed up by a second year of analysis covering two different test sites to:
The deliverables would be:
Landcare Research will be bidding for funding for this project, if accepted by the satellite operators, as part of their portfolio of work for the next 6 year time interval – 2006-2012.
In addition, there are a variety of funding opportunities for further development of this project. AgResearch is already a member of the NZ industry partnership evaluating a range of remote sensing opportunities in NZ, including “Pastures from Space”. There are opportunities for this project to work with this existing industry initiative.
