1) If my model outputs a shapefile with an attribute table with multiple rows, what is the best way to write the output from the attribute table to a new table? 2) How can I rearrange the cells from the attribute table to the new table? (I.e. merge two rows from the attribute table into one row in the final output table) 3) Finally, how can I have the results of other iterative runs of the model add on to the new table? I'm searching for solutions using either Python or ModelBuilder. These maybe newbie questions, but it is where I'm stuck. Looking forward to hearing back from you. Thanks!

I addressed Point 2 using a Similarity Search tool. Just need to iterate now.

I was able to address Point 1, however I'm still uncertain on how to Select By Attribute based on the most similar value rather than an exact value. Any ideas?

Hi Dan, I'm a bit stuck on the modeling for even one case. The two specific points I'm stuck on for modeling one case is: How do I select all the county polygons which are intersected by the edge of my circle polygon? How do I select by attribute based on the most similar value rather than an exact value? Any suggestions?

Hi, I have 120 individual data points (each representing a small airport) that I would like to perform the following analysis: Select a county that the airport is located in and extract a statistic from that county (e.g. income/capita). Let’s call this County A and the statistic X. Select another county (let’s call it County B) subjected to the following constraint: County B must be intersected by a circle of the same geodesic radius as the distance between the airport in County A and a central location. The selection of County B should be based on another given statistic of County B being most similar to County A. Let’s call this selection criteria statistic Y. (E.g. If statistic Y is population, I would like to select the county with closest population to County A that is intersected by the circle.) Extract the names of County A, B as well as statistic X, Y for County A and B to a table. Repeat for the other rows of data (i.e. the other small airports and central locations they are paired with.) The image below is an example of one of these situations. The small green dot towards the right is the airport in consideration, the selected county is County A in this situation. Thus, County B is the county that is closest to County A for a statistic Y (e.g. most similar in population) and is intersected by the geodesic circle. I believe this is a combination of Selection by Location and Selection by Attribute. Would Model Builder be the best approach for this problem? Thanks ahead for the help! Regards, Jao

Hi, I have a layer of 120 polylines created from XY coordinates of start and end points. I now would like to create a layer of circles (polylines not polygons) with one end point of each polyline as the center and the other end point of the polyline as the outer radius. How do I do this? Thanks!
