Geographic Information Technologies
Global Positioning Systems (GPS)
A system of Earth-orbiting satellites which provides precise location on the earth’s surface in lat./long coordinates.
11 hours 58 minutes orbital period
24 hour 3D coverage worldwide
Remote Sensing (RS)
Use of satellites/aircrafts to capture info-earth’s surface.
Digital ortho images a key product.
GIS are designed to answer thefollowings:
Location
Where are particular feature found?
Patterns
What geographical patterns exist?
Trends
Where have changes occurred over given period?
Conditions
Where do certain conditions apply?
Planning
• Involves surveys, review of exiting infrastructure.
• GIS- integrates, manage, analyze and visualize the wide range of data sets.
Design
• GIS- data management tools to manage and share data between GIS and CAD soln.
Maintenance
• Detailed understanding of the location of assets for transport infrastructure.
Information
• Up to date information systems for travellers.
• The wide choice of travel options require true multi-modal solutions.
Conclusion
With increasingly complex projects, GIS provides the civil engineers with tools for
Creating , managing , analysing and visualizing all types of geographic information.
GIS education is expected to prepare individuals in the civil engineering profession
for the implementation of engineering projects/tasks with time- and money-saving approaches.
