I am conducting a buffer analysis on a vector feature class of Urban-Wildland Interface zones, and am trying to calculate the total areas of each particular classification of interface area.
As I walk through this question, elements that represent column attributes will be [framed], and data will be indicated with (parentheses)
For example... Buffer A's [municipal_name] is (Charleston), and features [Interface_Type] (HighDensity_Interface); (HighDensity_Intermix); and (MedDensity_Interface) areas.
Buffer B's [municipal_name] is (Amherst), and features Interface_Type; (HighDensity_Intermix); and (LowDensity_Interface) areas.
- I have successfully isolated the two buffer areas using the "Identify" function. The vector data based on the original Urban-Wildland interface feature class is somewhat "checkerboarded" (metaphorically speaking) given the diversity of interface areas within each.
- I then added a new field and "calculated geometry", populating the new field with [Area] data
- Now, each metaphorical "square" in the "checkerboard" has an area calculated. For example 6 of the individual "squares" in (Amherst) have now had their (HighDensity_Interface) [Area] calculated, and so on with the other [Interface_Type].
Since (Amherst - Buffer B) and (Charleston - Buffer A) are in the same feature class, I am having a difficult time summarizing the areas of each interface type and aggregating those calculations based on [municipal_name].
Is there a way to do this in ArcMap? Or should I begin analyzing my tables in a separate statistical tool, such as SAS?
I tried doing a basic "dissolve" function, but that unites (HighDensity_Interface) across both buffers, which is not what I want.
- Is there a way to split this new "dissolved" feature class based on [municipal_name], separating results from (Amherst) and (Charleston)?
I may have just done things backwards... time for some more poking.
