With China Remote Sensing career advancement, a large number of independent researches and development satellites have launched. Among a new generation of high-resolution satellites, GaoFen-1 (GF-1) stands out. It sets high spatial resolution (2 m-16 m), multi-spectral and high temporal resolution (4-day) with 60 km-800 km swath in a fusion technology with strategic significance. In order to explore...
Two GF-1 WFV images on August 3, 2015 and October 2, 2015 were selected to extract the cultivated area of paddy rice in Jianhu county of Jiangsu Province. Vegetation indexes were extracted from the original spectrum data in order to extract paddy rice area with Maximum Likelihood Classifier (MLC), Support Vector Machine (SVM) and Classification and Regression Trees (CART). The extraction accuracy...
Agricultural landscape is designated as important landscape components for partly controlling water quality, biodiversity, as well as for their aesthetic role in landscapes. Therefore, the change of agricultural landscape is at the top of the agenda for many policy makers and landscape planners. As a basis for conservation management, sufficient information about landscape structure should be providing...
Crop phenology is a critical component of implementing agricultural activities and providing important indicators for climate related research. The needs for crop phenology estimation not only exist in large scale but also in medium or small scale. In this work, Jianhu County was chosen to test the ability of crop phenology estimation by Moderate Resolution Imaging Spectroradiometer (MODIS) data....
Coastal ecosystem is one of the most important ecosystems on the earth. However, the ecosystem is being fragile due to both anthropogenic (e.g., aquaculture) and natural (e.g., climate change) effects. The recurrent green algae blooms in the Yellow Sea, as one of the environmental disaster, affect the coastal ecosystem. Thus, detecting the origin of the algae and tracing the underlying causes are...
Crop Growth Condition (CGC) monitoring is one of the most important methods for the yield estimation and the food security. The needs for CGC monitoring not only exist in large scale but also in medium or small scale. In this work, Sihong County was chosen to test the ability of the 10-day CGC monitoring by remote sensing data. Over 600 Moderate Resolution Imaging Spectroradiometer (MODIS) 250-m resolution...
