FRINGE 2015 ABSTRACT Temporal tracking of rice paddy heights with TanDEM-X
نویسندگان
چکیده
Can the height of a rice plant be measured from space? TanDEM-X, a mission designed to generate high accuracy global elevation models, has been shown to be capable of doing just that [1]. The growth of a rice plant can be observed starting from its vegetative phase, through its maturation phase until harvest. The measured height is very accurate, with a root mean square error ranging from a few up to 20 centimeters, depending on the phenological phase. This result is of particular interest considering that the plant grows to only about 1.5 meters and the TanDEM-X system’s relative and absolute elevation accuracy requirements are on the order of meters.

Transferability of Models for Estimating Paddy Rice Biomass from Spatial Plant Height Data
It is known that plant height is a suitable parameter for estimating crop biomass. The aim of this study was to confirm the validity of spatial plant height data, which is derived from terrestrial laser scanning (TLS), as a non-destructive estimator for biomass of paddy rice on the field scale. Beyond that, the spatial and temporal transferability of established biomass regression models were i...
متن کاملMapping paddy rice planting area in wheat-rice double-cropped areas through integration of Landsat-8 OLI, MODIS, and PALSAR images
As farmland systems vary over space and time (season and year), accurate and updated maps of paddy rice are needed for studies of food security and environmental problems. We selected a wheat-rice double-cropped area from fragmented landscapes along the rural-urban complex (Jiangsu Province, China) and explored the potential utility of integrating time series optical images (Landsat-8, MODIS) a...
متن کاملMapping paddy rice planting areas through time series analysis of MODIS land surface temperature and vegetation index data.
Knowledge of the area and spatial distribution of paddy rice is important for assessment of food security, management of water resources, and estimation of greenhouse gas (methane) emissions. Paddy rice agriculture has expanded rapidly in northeastern China in the last decade, but there are no updated maps of paddy rice fields in the region. Existing algorithms for identifying paddy rice fields...
متن کاملMapping Paddy Rice Agriculture using Multi-temporal FORMOSAT-2 Images
Most paddy rice fields in East Asia are small parcels, and the weather conditions during the growing season are usually cloudy. FORMOSAT-2 multi-spectral images have an 8-meter resolution and one-day recurrence, ideal for mapping paddy rice fields in East Asia. To map rice fields, this study first determined the transplanting and the most active tillering stages of paddy rice and then used mult...
متن کاملObject-Based Paddy Rice Mapping Using HJ-1A/B Data and Temporal Features Extracted from Time Series MODIS NDVI Data
Accurate and timely mapping of paddy rice is vital for food security and environmental sustainability. This study evaluates the utility of temporal features extracted from coarse resolution data for object-based paddy rice classification of fine resolution data. The coarse resolution vegetation index data is first fused with the fine resolution data to generate the time series fine resolution d...
