Using GIS for Determining Variations in Health Access in Jeddah City, Saudi Arabia
2. Materials and Methods
2.1. Study Area
2.2. The Database
2.3. Network Analysis
3.1. Health Center Classification and Analysis
- Calculate the mean center of the input points. If a Population field other than None was selected, this, and all the following calculations, will be weighted by the values in that field.
- Calculate the distance from the (weighted) mean center for all points.
- Calculate the (weighted) median of these distances, Dm.
- Calculate the (weighted) Standard Distance, SD.
- Apply the following formula to calculate the bandwidth:
- SD is the standard distance
- Dm is the median distance
- n is the number of points if no population field is used, or if a population field is supplied, n is the sum of the population field value.
3.2. Access to Health Centers
3.3. Population within Access to Health Centers
