Thanks for your reply, Shana! I’m using the address locator from StreetMap, the same one I use when I do normal geocoding. Im using the reverse geocoding tool both in ET Geowizards and the tool in ArcMap. Is this helpful? Thanks so much!

Hi - I've done geocoding a lot in the past, but never reverse geocoding. I have a shapefile that has lat/longs and an ID, and when I try to reverse geocode, the fields returned are blank. My data is projected. My address locator is "Street_Addresses_US". Any thoughts as to why? Thanks so much!

Ok yes, that’s helpful. Thanks! On a somewhat related note, when traveling along the network dataset to get the distance from one point to another, when it stops at the end point, it stops right in front of the point on that road, correct? Assuming there are no restrictions. So if there was a parking lot or a large amount of space between the road and the end point, it would still end on that road (it wouldn’t take you right to the point if there was no underlying road). Does that make sense? Is that correct?

Not particularly confusing, I'm just trying to explain it to a non-GIS user and was hoping to find a website with a clear definition to point her to. But you confirmed my self-made definition so that's helpful! Thank you!

I'm trying to find a proper definition for "Non-routeable segments" within the Layer Properties. I have a general idea of the meaning and I've seen some websites mentioning it, but nothing definitive. Can anyone help me out with the difference between "routable" and "non-routable" roadway segments?

See image. I'm trying to perform a spatial join (one to many). for the "places" city shapefile (blue polygons) and the US counties shapefile (pink polygons with red outlines). I want a list of all of my cities (blue polygons) and the counties they overlap. The problem I run into is the type of polygon on the left side of the image. It's exactly the same shape as the underlying polygon, so when I join the two together, it returns all of the surrounding counties (when I really just want the underlying county). I'm trying to use Clementini for a one to many join (because like the polygon on the right, it overlaps two counties), but the results don't give me a one to many, just one county per city polygon. Does this help?

It does look like Within Clementini is what I need to be using, but it doesn't seem to give a "one to many" output for those city polygons that overlap more than one county. Does this function allow for a one to many output?

Hello! I'm trying to perform a spatial join (one to many). for the "places" city shapefile and the US counties shapefile. I want to see all of the counties the places shapefiles overlap, but because some of the places share a boundary with the counties, it includes those counties as well (something I'm trying to avoid). How do I omit those counties that only share a border with a place shapefile? I considered converting polygons to points, but then I wouldn't get all of the counties if some place shapefiles overlap. Does this make sense? Thank you!

Ahhh yes - a spatial join one to many did the trick! Thank you, Dan!

Hello! I have two poylgon layers (census tracts and a list of 1,000 buffers) and am trying to get a list of all census tracts that intersect the polygons from the other layer. I run the intersect tool, but come up with this issue: my polygon layer of 1,000 records sometimes overlap each other, so the intersect tool counts those overlaps as intersecting - does this make sense? So in one example I'm seeing, one polygon should overlap 12 census tracts, but the intersect tool returns a count of 48 overlaps because it's counting the other polygons that it's overlapping. So basically, I need a list of which tracts intersect my polygon layer, but the intersect tool is returning too many records and is not accurate. Is this the correct tool I should be using? Thank you!!

Good idea. I have a list of 1200+ polygons and a separate list of 400+ points located all throughout California. I need the roadway distance from those 400 points to the 1200 polygons. So then how would I pick which point (created by the intersect tool using the roads/polygons) for it to go to? Ideally, I'd want the closest part of the polygon to the original point. Does that make sense? Not sure how I'd pick each point for it to go to, especially since it's such a large dataset.

‎09-18-2017

Oh, interesting! So I'd just run the intersect tool with all of my roads (I'm working with California) and all of my polygons. Then the output would be points. And I would use those points as my location? Would the output be the central point in those polygons? P.S. Thanks for always answering my questions, Dan!

Hello. I need to map the roadway distance from a point to a polygon (or polygon to polygon). Is this possible in either ArcMap (preferred method - I work on this regularly) or qGIS? I know I can't add polygons as a location in Network Analyst so I'm not sure if it's possible. Thank you!

‎08-24-2017

Ahhhh - that is super helpful! I was able to do it - thanks! Related question, if you know the answer. I have 7 polygon buffers, which points inside each buffer that needs to use the route tool. So I don't want it to cross the buffer line, I want to use the route tool for inside each buffer, but can I run the route tool only one time? I tried using polygon barriers, but it seemed to think inside the polygon was a barrier. Does my wording make sense?

I just get distances from one point to all other points. I think my problem is the travelling salesman problem, but I only get one measurement instead of the distance from each location.
