GIS

AN OVERVIEW

                                                                           

                                                

• For simplicity's sake we often call GIS "mapping software.“

GIS gives a pictorial presentation of information; ‘a picture is worth a million words’

Total: 11,170 Hhs - Require IMMEDIATE assistance, at leastuntil late October or Deyr rains & perhaps longer.Figure increased from 9,000 Hhs identified in May due to;- Hagay season (dry period)- More wealthier Hhs affected (especially due to camel deaths)

• Simply put, a GIS combines layers of information about a place to give you a better understanding of that place.

Why Use GIS?

• 1: Improve Organizational Integration

One of the main benefits of GIS is improved management of your organization and resources. A GIS can link data sets together by common locational data, such as Health facility name, which helps and agencies share their data. By creating a shared database, one department can benefit from the work of another—data can be collected once and used many times

2: Make Better Decisions • The old adage "better information leads to better

decisions" is true for GIS. A GIS is not just an automated decision making system but a tool to query, analyze, and map data in support of the decision making process.

• For example, GIS can be used to help reach a decision about the location of a the most affected persons given a certain environmental impact; answer questions like where are they, How many, logistics for intervention etc.

• The information can be presented succinctly and clearly in the form of a map and accompanying report, allowing decision makers to focus on the real issues rather than trying to understand the data. Because GIS products can be produced quickly, multiple scenarios can be evaluated efficiently and effectively.

Map products can then be created centered on any location, at any scale, and showing selected information symbolized effectively to highlight specific characteristics. A map can be created anytime to any scale for anyone, as long as you have the data.

This is important because often we say "I see" to mean "I understand." Pattern recognition is something human beings excel at. There is a vast difference between seeing data in a table of rows and columns and seeing it presented in the form of a map. The difference is not simply aesthetic, it is conceptual—it turns out that the way you see your data has a profound effect on the connections you make and the conclusions you draw from it. GIS gives you the layout and drawing tools that help present facts with clear, compelling documents.

3: Make Maps

• For simplicity's sake we often call GIS "mapping software." We most often associate maps with physical geography, but the map to the right demonstrates that GIS is flexible enough to map any kind of terrain, even the human body. GIS can map any data you wish.

GIS in Food and Nutrition Surveillance

Basic information that may needed:

-Settlements: rural and urban

(e.g villages and towns)

-Administrative boundaries (line and polygon)

-Demography

- Communications network (roads, rails etc)

-Geographic features (rivers, lakes, mountains etc)

Hardware and Software

-Computer

-GIS software: Arcview, arc Info, Map Info etc

Image processing: Erdas, Idrisi, Ilwis etc
