I want to look at the accessibility of health care facilities for a class project for the city of Chicago. I was told to do the two-step floating catchment area to measure accessibility. I did a spatial join with census tract to create a count field for the number of facilities within the census tracts. Then a created centroids for each census tracts to establish a Service Area with Network Analysis. Afterwards, I also created a service area for the facilities. Now I am stuck; I do not know where to go next. I am aware that the two-step floating catchment area is an equation but I am not sure even how to do it or where to do it. Do I now do a spatial join with the two Service Area that I created and then add a new field and calculate the equation there or did I do a Clip to gain attribute information, then the equation? Can anyone direct me to a tutorial or somewhere that can help me?
