Quality Assessment of the French OpenStreetMap Dataset
Tập 14 Số 4 - Trang 435-459 - 2010
Jean‐François Girres, Guillaume Touya
AbstractThe concept of Volunteered Geographic Information (VGI) has recently emerged from the new Web 2.0 technologies. The OpenStreetMap project is currently the most significant example of a system based on VGI. It aims at producing free vector geographic databases using contributions from Internet users. Spatial data quality becomes a key consideration in this c...... hiện toàn bộ
Integration of Space Syntax into GIS: New Perspectives for Urban Morphology
Tập 6 Số 3 - Trang 295-309 - 2002
Bin Jiang, Christophe Claramunt
The research field of transportation demand forecasting has started to focus on disaggregate travel behavior and micro‐simulation models. To create data infrastructure, disaggregate trip surveys are conducted and large numbers of observations are collected. To efficiently exploit these surveys, the transfer of the individual trip data to a GIS must start with the development of a solid con...... hiện toàn bộ
The Effect of DEM Raster Resolution on First Order, Second Order and Compound Terrain Derivatives
Tập 8 Số 1 - Trang 83-111 - 2004
S. W. Kienzle
AbstractIt is well known that the grid cell size of a raster digital elevation model has significant effects on derived terrain variables such as slope, aspect, plan and profile curvature or the wetness index. In this paper the quality of DEMs derived from the interpolation of photogrammetrically derived elevation points in Alberta, Canada, is tested. DEMs with gri...... hiện toàn bộ
Spatial Prediction of Landslide Hazard Using Logistic Regression and ROC Analysis

Toward Optimal Calibration of the SLEUTH Land Use Change Model
Tập 11 Số 1 - Trang 29-45 - 2007
Charles Dietzel, Keith Clarke
AbstractSLEUTH is a computational simulation model that uses adaptive cellular automata to simulate the way cities grow and change their surrounding land uses. It has long been known that models are of most value when calibrated, and that using back‐casting (testing against known prior data) is an effective calibration method. SLEUTH's calibration uses the brute fo...... hiện toàn bộ
Mapping Large Spatial Flow Data with Hierarchical Clustering
Tập 18 Số 3 - Trang 421-435 - 2014
Xi Zhu, Diansheng Guo
AbstractIt is challenging to map large spatial flow data due to the problem of occlusion and cluttered display, where hundreds of thousands of flows overlap and intersect each other. Existing flow mapping approaches often aggregate flows using predetermined high‐level geographic units (e.g. states) or bundling partial flow lines that are close in space, both of whi...... hiện toàn bộ
A Characteristic‐Hull Based Method for Home Range Estimation
Tập 13 Số 5-6 - Trang 527-537 - 2009
Joni Downs, Mark W. Horner
AbstractRecent literature has reported inaccuracies associated with some popular home range estimators such as kernel density estimation, especially when applied to point patterns of complex shapes. This study explores the use of characteristic hull polygons (CHPs) as a new method of home range estimation. CHPs are special bounding polygons created in GIS that can ...... hiện toàn bộ
Spatial Differences in Multi‐Resolution Urban Automata Modeling
Tập 8 Số 4 - Trang 479-492 - 2004
Charles Dietzel, Keith Clarke
AbstractThe last decade has seen a renaissance in spatial modeling. Increased computational power and the greater availability of spatial data have aided in the creation of new modeling techniques for studying and predicting the growth of cities and urban areas. Cellular automata is one modeling technique that has become widely used and cited in the literature; yet...... hiện toàn bộ
Consistency among parts and aggregates: A computational model
Tập 1 Số 3 - Trang 189-206 - 1996
Nectaria Tryfona, Max J. Egenhofer
Heterogeneous geographic databases contain multiple views of the same geographic objects at different levels of spatial resolution. When users perceive geographic objects as one spatial unit, although they are physically separated into multiple parts, appropriate methods are needed to assess the consistency among the aggregate and the parts. The critical aspect is that the overall spatial ...... hiện toàn bộ
