Using MODIS data over China for the 2000-2008 period, we performed a statistical analysis of the apparent reflectance difference of two blue bands (BRD) between the 469nm and 415nm over ocean and land. The results showed that the BRD gives a discrimination of heavy biomass burned smoke and dust from others phenomena such as cloud, snow/ice, haze and clear-sky surface. It indicates that the MODIS blue...
Leaf area index (LAI) is an essential parameter for monitoring crop growth dynamic. An algorithm, which is based on physical model and neural networks to derive crop LAI from MODIS land surface reflectance, is presented. This algorithm utilizes the directional reflectances instead of the BRDF normalized data to avoid complex BRDF normalization and the error from it. The estimated LAI is compared with...
The information of urban road surface facilities cannot be updated in a timely fashion. This has been identified as an urgent problem to urban manager in some cities of China where the speed of economic development and the population growth is fast. This paper presents an Urban Road Surface Facilities Management System (URSFMS) based on Mobile Mapping System for updating system database timely. URSFMS...
