The long-time historical evolution and recent rapid development of Beijing, China, present before us a unique urban structure. A 10-metre spatial resolution SPOT panchromatic image of Beijing has been studied to capture the spatial patterns of the city. Supervised image classifications were performed using statistical and structural texture features(More)
Using airborne multispectral digital camera imagery, we compared a number of feature combination techniques in image classification to distinguish vineyard from non-vineyard land-cover types in northern California. Image processing techniques were applied to raw images to generate feature images including grey level co-occurrence based texture measures, low(More)
We developed a method for integrated analysis of multi-source data for vegetation classification at the continental scale, and applied it to China. Multi-temporal 1 km NOAA Advanced Very High Resolution Radiometer (AVHRR) Holdridge's life zone system and its vegetation–climate classification indices such as bio-temperature (BT), potential evapotranspiration(More)
There are two X-band ripples horn single-lens antennas, waveguide transmission segment, fixture, a mounting station, an Agilent N5225A network analyzer and a computer in the free-space measurement system of 8GHz~40GHz frequency range. S<sub>11</sub> and S<sub>21</sub> of sample measured by network analyzer are used to calculate the dielectric constant. A(More)
