National Mapping of New Zealand Pasture Productivity Using Temporal Sentinel-2 Data

نویسندگان

چکیده

A national map of pasture productivity, in terms mass dry matter yield per unit area and time, enables evaluation regional local land-use suitability. Difficulty measuring this quantity at scale directed research, which utilises four years Sentinel-2 satellite imagery collected measurements to develop a model productivity. The uses Normalised Difference Vegetation Index (NDVI), with spatio-temporal segmentation averaging, estimate mean annual productivity across all New Zealand’s grasslands standard error prediction 2.2 t/ha/y. Regional aggregates demonstrate expected spatial variations. may be used classify objectively into stratified levels production on scale. Due its ability highlight areas land use intensification suitability, the is value landowners, users, environmental scientists.

Pasture species and cultivars used in New Zealand – a list

In recent years, the number of pasture species and cultivars commercially available to farmers in New Zealand has increased significantly. Reasons for this include increased commercial activity in the development and supply of proprietary cultivars, and more specialisation in New Zealand’s pastoral agriculture. In particular, pasture cultivars are increasingly marketed as proprietary products w...

Potential of Resolution-Enhanced Hyperspectral Data for Mineral Mapping Using Simulated EnMAP and Sentinel-2 Images

Spaceborne hyperspectral images are useful for large scale mineral mapping. Acquired at a ground sampling distance (GSD) of 30 m, the Environmental Mapping and Analysis Program (EnMAP) will be capable of putting many issues related to environment monitoring and resource exploration in perspective with measurements in the spectral range between 420 and 2450 nm. However, a higher spatial resoluti...

Comprehensive Annual Ice Sheet Velocity Mapping Using Landsat-8, Sentinel-1, and RADARSAT-2 Data

Satellite remote sensing data including Landsat-8 (optical), Sentinel-1, and RADARSAT-2 (synthetic aperture radar (SAR) missions) have recently become routinely available for large scale ice velocity mapping of ice sheets in Greenland and Antarctica. These datasets are too large in size to be processed and calibrated manually as done in the past. Here, we describe a methodology to process the S...

Feasibility of sentinel lymph node mapping in renal cell carcinoma using intraoperative radiotracer injection

Introduction: The applicability of sentinel lymph node biopsy for early detection of metastasis in patients with renal cell carcinoma (RCC) is still in the validation phase and under investigation, which might be due to the unpredictability of the lymphatic pattern in RCC. In this study, we aimed to evaluate the feasibility and accuracy of sentinel node biopsy in patients with ...
