Binary and Ordinal Data for Kirging or other Interpolation techniques?

Hi all,

I have a question regarding interpolation technique and I hope someone here can give me some help. I???ve done the Geostatistic ESRI online tutorial, which I am pretty sure many people in this forum have also completed. The tutorial used all sort of interpolation tools to predict Ozone level across California based on continuous data collected from air quality stations.

I would like to do the same thing but I am wondering if I can do this for ordinal or binary data. For example, I have some public transit satisfaction level data from a public transit customer satisfaction survey. In this case I am almost certain that you can use Kirging to predict the satisfaction level across the study area base on sample data. However, I am wondering if we can do interpolation on binary data. For example, when the survey ask if you have ever used public transit there will be a Yes or No answer. Similar to binary regression, I am thinking if I can assign a dummy variable (Yes = 1, No = 0) as the input in the ArcGIS interpolation tool to predict the location of the public transit users and the non-public transit users across the study area.

Thanks,
Jason
