3 Introduction -In srok Peareang (Prey veaeng Province) lack Health Centers in other khums. -People difficultly go to Health Center (far a way from 3-4 Kilometers). -So I chose the Tool in GIS for analysis this project. Introduction Stating problemBreak down the problemResultPerforming Analysis

4 Stating the Problem My problem is to find the suitable location for siting a new health center in srok peareang (Prey veaeng province). The result is a map showing potential sites (ranked best to worst). Introduction Stating problemBreak down the problemResultPerforming Analysis

5 Breaking down the Problem Best site For new Health Center Near the high population A way from Existing health centers Built on Agriculture land,… Near the Road Introduction Stating problemBreak down the problemResultPerforming Analysis

6 Diagram Process Best site For new Health Center Calculate distanceCalculate density Population Density Population Health Centers Distance Health Centers Roads Distance from Roads Land Use Raster Land Use Convert to Raster Introduction Stating problemBreak down the problemResultPerforming Analysis

7 Near the high population It is preferable to locate the new Health center close to high population. So we need to create a map displaying the density of population. By using : Density function Picture: Density Introduction Stating problemBreak down the problemResultPerforming Analysis

8 Near the high population Introduction Stating problemBreak down the problemResultPerforming Analysis

10 Near the high population Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

11 A way from Existing health centers We want to site new health centers a way from existing health centers. So we need to create a map displaying the distance to health centers. By using : StraightLine function Picture: StraightLine Introduction Stating problemBreak down the problemResultPerforming Analysis

12 A way from Existing health centers Introduction Stating problemBreak down the problemResultPerforming Analysis

13 A way from Existing health centers Introduction Stating problemBreak down the problemResultPerforming Analysis

14 A way from Existing health centers Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

15 Near the Road To find area that near the road to make easy for people to find it. So We need to create a map to display the distance from the nearest to far a way. By using : StraightLine function Introduction Stating problemBreak down the problemResultPerforming Analysis

16 Near the Road Introduction Stating problemBreak down the problemResultPerforming Analysis

17 Near the Road Introduction Stating problemBreak down the problemResultPerforming Analysis

18 Near the Road Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

19 Built on Agriculture land,… A agricultural land is considered the least costly to built on and therefore the most preferable. The Barren land is next, then move on … This process is convert form feature to Raster and,just identify the land use are most preferable to built on. Picture: Convert (feature->Raster) Introduction Stating problemBreak down the problemResultPerforming Analysis

20 After we just broke down problem. We move on to reclassify(Reclassify function) all elements and combine by using function Raster Calculator. There are two ways to find the best location for built new health center : - combining all elements by provide each a percentage influence. - Query Introduction Stating problemBreak down the problemResultPerforming Analysis

23 Reclassify Distance of Health Center Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

24 Reclassify Distance of Road Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

25 Reclassify Distance of Road No Data Before After Introduction Stating problemBreak down the problemResultPerforming Analysis

26 When We reclassified all elements, we need use Raster Calculator function. We need to provide the number of percentage influence : - Land use : 0.15 (15%) - Road : 0.15 (15%) - Health Center : 0.30 (30%) - Density population : 0.40 (40%) Picture: Raster Calculator Introduction Stating problemBreak down the problemResultPerforming Analysis

27 Result Introduction Stating problemBreak down the problemResultPerforming Analysis

28 Conclusion - The result is one level. Lack Data Lack technique to analysis and use tools - But GIS is useful to display data for both presentation and analysis as well ( ability to process data).
