GIS-What is it?
GIS
• Computer-based Technology
• Designed with software, hardware, data, procedure,
network and live ware.
• Storage, retrieval, mapping and analysis of
geographic data.
• Data is stored in coordinate form.
• Layered together for mapping analysis.
GIS Functions
GPS satellites
• Stores in Vector or Raster format
• Spatial and Attribute data
• Identifying specific features
• Identifying features based on conditions
• Proximity analysis
• Overlay analysis-overlap 2 layers
• Network analysis-examines linear features
• Visualized as a maps
• Reports, 3-D views, photographs
• Paper map, Document, Image
• Internet
TRANSPORTATION
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 infrast.
Information
• Up to date information systems for travellers.
• The wide choice of travel options require true multi-modal solutions.
Conclusion
Geographic information is at the heart of all engineering
projects.
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.
