How to transfer GPS heights into normal heights has become a hotspot in survey engineering. With the development of computer and information technology, artificial neural networks (ANN) has been used widely, which has the character of the high parallel distributed processing, associative memory abilities, self-organization, self-learning and strong nonlinear mapping abilities, and the theory has proved...
Artificial neural networks (ANN) has been used in GPS heights conversion. It is impossible to avoid gross errors in conversion of GPS heights. So, the paper puts forward a kind algorithm to detect gross error considering of ANN used in conversion of GPS heights. After the three tests, the algorithm proposed for disposing of gross error is validated in conversion of GPS heights, and some practicable...
How to effectively monitor water quality of Coastal and inland waters by optical remote sensing has always been a difficulty. This study develops a neural network model to improve the accuracy in monitoring water quality of Lake Taihu, China, a large shallow subtropical lake. A three-layer back-propagation neural network is built up to estimate concentrations of chlorophyll-a, total suspended matter...
