| Zusammenfassung |
| Assessment of geological hazards in urban areas must integrate geospatial
and temporal data, such as complex geology, highly irregular ground surface,
fluctuations in pore-water pressure, surface displacements and environmental
factors. Site investigation for geological hazard studies frequently
produces surface maps, geological information from borehole data, laboratory
test results and monitoring data. Specialized web-based GIS tools were
created to facilitate geospatial analyses of displacement data from
inclinometers and pore pressure data from piezometers as well as geological
information from boreholes and surface mapping. A variety of visual aids in
terms of graphs or charts can be created in the web page on the fly, e.g. displacement vector, time displacement and summaries of geotechnical testing
results. High-resolution satellite or aerial images and LiDAR data can also
be effectively managed, facilitating fast and preliminary hazard assessment.
A preliminary geohazard assessment using the web based tools was carried out
for the Town of Peace River. |
