I have to calculate the GiZScores to Dengue incidences in District wise.This should be done using ArcGIS software by using Getis Ord GIS tool. But the problem is that I have to use climatic factors (rainfall,temperature,humidity) weights matrix file as my "Conceptualization of Spatial Relationships". I want to know that how to make this weight matrix file. Can anyone explain the method to do this to me? I have all the climatic data for each district, weather station locations (weather stations are not located in each district).
