Slide 23 of 24
Notes:
One important limitation of this study is the fact that the average maps are based on a rather small number of individual maps. In order to ensure statistical reliability we need to increase the N to about 30 maps per area. We intend to do this by sending maps to some of the respondents to our telephone survey asking them to color black and white maps, in a similar manner to the procedure used during the focus group sessions.
Map generation for this project will not be resumed to digitizing hand drawn maps. Based on a set of survey questions, which asked respondents to indicate the cross streets close the the areas they go most often or they try to avoid, we will be able to build point theme maps. These maps then can be used for further analysis, including spatial correlation and autocorrelation. Also, by using interpolation techniques, such as kriging, we will be able to generate continuous coverage maps. These maps, if converted to grid files, could then be used for comparing the maps generated from the hand drawn maps.
Another series of items in the survey asked the respondents to what degree do they visit each other’s neighborhoods. This data can then compared, at community level, to data obtained from the comfort maps. Statistical correlation could again reveal if the maps are associated or not.
