Information on crop types derived from remotely sensed images provides valuable input for many applications such as crop growth modeling and yield forecasting. In this paper, a random forest (RF) classifier was used for crop classification using multispectral RapidEye imagery over two study sites, one in north-eastern China and one in eastern Ontario, Canada. Both vegetation indices (VIs) and textural...
Plant community is a significant content in the ecosystem. Traditional investigation method for plant community is mainly based on field sampling, which is limited by the data acquisition from complex terrain areas. In contrast, high-resolution remote sensing technique provides a convenient way to quickly access data in a large area. higher dimensional information is needed to distinguish more fine...
Assessment of land condition is a basic prerequisite for finding the degradation of a territory under climatic and human pressures leading to desertification. The temporal change in vegetation productivity is a key indicator of land degradation. In this paper, taking the Beijing-Tianjin dust and sandstorm source region (BTDSSR) as a case, the annual-maximum normalized difference vegetation index (NDVI_max)...
In industry the line dispensing system has been widely used to squeeze the adhesive fluid in a syringe onto boards or substrates with the pressurized air. For consistent dispensing, it is vital to have a robust dispensing system insensitive to operation condition variation. To address this issue, much research effort has been done. However, a systematic design approach to determine an optimal operation...
