This paper uses GMDH method to establish a prediction model to forecast the output value of transport & storage of Guangdong in China, since the original samples of the output value of transport & storage are less enough to be used with the traditional methods. Compared with traditional linear regression and artificial neural network, the predicted results show that GMDH method is an effective...
Motion data storage in 3D GIS has a lot of special requirements than other data storage, especially motion data coding. The management of motion data based on sampling requires the flexible balance of data quantity, quality and process complexity, i.e. the compression ratio, precision and processing time. Grid coding together with bit assembly works well to meet the requirements. An experiment designed...
