Anna University, Chennai

Abstract
Public health management needs information on various aspects like the prevalence of diseases, facilities that are available in order to take decisions on either creating infrastructure facilities or for taking immediate action to handle the situation and so on. These decisions need to be taken based on the observations made and available data.

      ArcGIS Network Analist Step 4

      This Tutorial is Separated in to Five steps :

        1. a. Step 1 Preparing The Dataset
        2. b. Step 2 Creating a Multimodal Network Dataset
        3. c. Step 3 Finding a Route

        5. e. Step 5 Creating a Model For route Analysis

          Exercise 6: Calculating service area and creating a OD Cost Matrix

          In this Exercise you will create a series of polygons representing the distance that can be reached from a facility within a specifi ed amount of time. These polygons are known as service area polygons. You will calculate 3-, 5-, and 10-minute service area polygons for six warehouses in Paris. You will also fi nd out how many stores lie within each of these service areas. You have to identify one warehouse that should be relocated to better service the stores. Additionally, you will create an Origin- Destination Cost Matrix for delivery of goods from the warehouses to all the stores within a 10-minute drive time. Such a matrix is used as an input for logistics, delivery, and routing analyses.

              Abstract
              Landslides occur in different parts of Southeastern Nigeria due to widespread impact of gully erosion resulting from annual rainfall and subsequent flooding. In this area landslide occur mostly as earth movement, rock and debris flows on slopes previously weakened by flood water. Remotely sensed images combined with field observation were used in this study to map potential areas of landslides in south – central parts of Anambra State in Southeastern Nigeria. The study generated landslide zonation map highlighting areas of different degrees of susceptibility and confirmed the possibility of using medium scaled remotely sensed data in landslide susceptibility study.

              Head of image processor at SSTEC (Satellite Science & Technology Engineering Co)

              Abstract
              Concerning the importance of carbonates in mineralization and the necessity of separation of important formations in remote sensing data, we try to separate carbonates into two groups including limestone and dolomite by using PCA on ASTER SWIR bands. As you know this analysis results can be used in compiling geological maps and GIS modeling for finding the favorable potential area.

              Flood Hazard Mapping is a vital component for appropriate land use planning in flood-prone areas. It creates easily-read, rapidly-accessible charts and maps which facilitates the administrators and planners to identify areas of risk and prioritize their mitigation/ response efforts. This article presents an efficient methodology to accurately delineate the flood-hazard areas in the Kosi River Basin, North Bihar, India in a GIS environment.
