Determination of Optimal Sampling Design for Spatial Data Analysis

Extended Abstract. Inferences for spatial data are affected substantially by the spatial configuration of the network of sites where measurements are taken. Consider the following standard data-model framework for spatial data. Suppose a continuous, spatially-varying quantity, Z, is to be observed at a predetermined number, n, of points ....[ To Countinue Click here]

Utilizing Repeated Gps Surveys from Field Operations

Topographic data collected using RTK‐DGPS‐equipped farm vehicles during field operations could add additional benefits to the original capital investment in the equipment through the development of high‐accuracy field DEMs. Repeated surveys of elevation data from field operations may improve DEM accuracy over time. However, minimizing the amount of data to be processed and stored is also an imp...

The Attitude Determination Algorithm Using Integrated Gps/ins Data

Traditionally, the extended Kalman filter (EKF) is a well known approach for general nonlinear data fusion problem. But the unit norm constraint of quaternion vector, which is the most efficient expression of attitude, results in the singularity of error covariance matrix. To overcome this difficulty, the modified extended Kalman filter (MEKF) has been developed by Shuster (1982). In order to i...

Simplifying GPS Trajectory Data with Enhanced Spatial-Temporal Constraints

Raw GPS trajectory data are often very large and use up excessive storage space. The efficiency and accuracy of activity patterns analysis or individual–environment interaction modeling using such data may be compromised due to data size and computational needs. Line generalization algorithms may be used to simplify GPS trajectories. However, traditional algorithms focus on geometric characteri...

Mining Spatial Data from Gps Traces for Automatic Road Network Extraction

The car manufacturing industry has been conducting a considerable effort to allow future vehicles to communicate, either between them or with a road infrastructure, in order to improve driving safety. As the position of each vehicle is an essential attribute of the proposed application protocols (to avoid collisions at blind intersections, for instance), and is also fundamental to support compl...
