GIS analysis of water point distribution across constituencies in Nakuru County, Kenya. # Kenya Water Points – Nakuru County ## Project Overview This project analyses the spatial distribution of water points across constituencies in **Nakuru County, Kenya** using Geographic Information Systems (GIS). The analysis uses a national water-point dataset and administrative constituency boundaries to identify how water points are distributed geographically and provide a clear visual representation of water-source availability across Nakuru County. ## Objectives * Map the distribution of water points across Nakuru County. * Aggregate water points by constituency. * Identify differences in the number of water points between constituencies. * Demonstrate the application of spatial analysis techniques using ArcGIS Pro. * Produce a professional map suitable for planning, monitoring and GIS portfolio purposes. ## Data **Water point data:** Kenya Water Points dataset **Data provider:** ICPAC **Publication date:** 2017 **Number of water-point records analysed:** 21,310 **Administrative data:** Constituency boundaries for Nakuru County, Kenya. **Coordinate Reference System:** WGS 84 (EPSG:4326) ## Methodology The analysis was completed using **ArcGIS Pro**. ### Workflow 1. Imported the Kenya water-point dataset into ArcGIS Pro. 2. Prepared the water-point and administrative boundary datasets. 3. Performed a **Spatial Join** to associate water points with their respective constituencies. 4. Aggregated the water points by constituency. 5. Isolated the constituencies within Nakuru County. 6. Applied graduated symbology to visualize differences in water-point counts. 7. Designed a professional cartographic layout including: * Title * Subtitle * Legend * Coordinate grid * North arrow * Scale bar * Data source * Author and date 8. Exported the final map as PDF and PNG. ## Final Map **View the high-resolution PDF map** ## Key Outputs The project produced: * A constituency-level water-point distribution map for Nakuru County. * A spatially joined dataset …
