What is GIS?

GIS is computer-based system that can be deal with virtually any type of information about features that can be referenced by geographical location.It is a powerful computer mapping and analysis technology that allows large quantities of information to be visualized and analyzed within a geographic context.

GIS in Managing Natural Resources

Types of Information needed to build-up effective GIS in Natural Resources

• Agricultural Information.

• Socioeconomics data (population data,…).

• Natural Resources data.

•Remote Sensing of Satellite Imagery.

• Nutrional and Health Information.

• Meteorological indicators.

GIS in Avoiding-Reduction of Major Hazards

A Natural Hazard is an unexpected or uncontrollable natural event of unusual magnitude

that threatens the activities of people or people themselves.

A Natural Disaster is a natural hazard event that actually resulted in widespread destruction of

property or caused injury and/or death.

GIS is useful in Assessing Major Hazards

• Geological Hazards (Landslides, Earthquakes, etc..)

• Meteorological Hazards (Floods, Drought, Dust Storm,..)

• Biological Hazard (Devastation of Vegetation).

• Other hazards (Forest Fires).

Flood!! How GIS can assist?

Drainage and Flood Prone Areas

Nile Flood prone Drainage (Wadi)

High risk areas always near the Nile.Very low risk at Wadis prone areas only
