Check your data for null or some other weird value.  You could also try to select a few and export them; if that works, then you've got a problem somewhere in the data.  And, check the field names; excel is famous for spaces or special characters that ArcGIS does not like ... View more

Thx Jay, I think I have located it....let me do this again at my end and will write back if I have further questions. Deb I'd really like to hear how this turns out for you.  Good luck with it.... ... View more

But can the users edit any other fc in that fgdb?  If they can then it's weirder than a permissions issue, right? ... View more

This is a total WAG (wild a** guess), but what are the permission/privileges on the geocoding results point feature class?  If you are working in the SDE environment, wouldn't that feature class need to be registered as versioned? Sorry this isn't much help but might be worth looking into.  While I use an SDE locator, I typically write the results to a pgdb or a fgdb so I've never encountered what you are experiencing. ...

Why don't you guys just give it a try and let the rest of us know what you find out?  If it's a published resource, my guess is it ought to work... ... View more

Deb-  I just took a peek at your data; you only have 13483 roads in your network: 13070 have a value of 0 (zero) minutes. You are basing your analysis on drive time and using the minutes field as your basis of accumulation.  If the vast majority of your roads have no time calculated, then the 5,10,15, or any amount of time is never met. See attached jpg; I selected minutes = 0. ... View more

Hi All, I am having some similar problem: 1) I need to find the service area within 5, 10, 15 minutes of the county centroids. When i solve that with the create new service area tool of network analyst it doesn't give the correct answer (it selects the whole state of Texas for some of the points which is wrong. It should create concentric  circles around the county centroids with regions at 5, 10, 15 minutes from those points). 2) I am having the same issue with the cities too. When I try to create a service area within 3 hours from San Antonio, Austin, Houston and Dallas it selects the whole of Texas. In fact it should create a circle around the city with areas within 3 hrs from it. The data is at the following site: http://kbdi.tamu.edu/SHRP2/Projected/deb.zip I am attaching a screenshot for this. i would greatly appreciate if you could kindly look into the matter and get back to me at the earliest. 1. I have never seen nor expected to see concentric circles around any location for which I've created a service area for.  It just dosen't work that way.  I haven't looked at your data, but you should; obviously there is a problem with the way your travel time calculation is or isn't working to be able to drive 15 minutes across Texas. 2. Again, it won't create a circle.  Leave that misconception behind.  And again, look more closely at your data and or you drive time calculations. ... View more

The city I work for is looking for a real-time routing solution for tree cleanup, and I know I can build a model to do the routing, but I can't figure out the first half of the solution to have a comprehensive point file for the routing to be applied to the model, because it wouldn't be me creating this, and after every "storm" it would be a different set of points.  They would need to be able to access this at any time of day, to be able to add new points when a complaint is lodged by a resident, or one is found by the clean-up crew. I am just kind of stumped on how to streamline this part.  I have network analyst. This seems to me a fairly complex issue; have you considered some sort of on-line geocoding service that could interact with your networking solution?  It'll never truly be in real time as it will take time to geocode the address(es) and then add them as part of the stops. ...

Good day everyone! When I chose a retailer location on my map, the coordinates indicate a different position from the real adress of retailers. The difference is between 50-150 meters. I am triyng to find out what caused this type of errors?! Thank you in advance for your time and patience! You mention 'real address'; is this an indication of 'real location'?  How did you obtain the coordinates for your retailers?  If they were geocoded with an 'address' against a street layer of address ranges, your precision issues should be expected. Let's say we have a street layer and we match an address 150 Main St against it.  The geocoder looks for a street called Main ST and finds a segment that has a range of 100-200 on the even side and 101-199 on the odd side.  It's going to figure that address 150 is right in the middle of the block on the even side.  The reality might be that the building with 150 painted on the front door is actually at one end of the block.  Accuracy in geocoding is one thing; in my example above, the locator is accurate to the block.  If you want precision, that is a X,Y value that better represents the actual location of address 150, you'll need to match against a data source that is better precision built into it (like address points, derived from parcels, gps'd points etc) rather than interpolating against a linear feature. Hope this helps- ... View more

I am wanting to do Location-Allocation analysis (minimize facilities) using network analyst, but I need the maximum distance to be as the crow flies, and not a distance down a road in my network.  Currently it works really well, doing what I'd expect it to do, highlighting the minimum facilities I need, however this is all based on a maximum distance down a road.  I need the maximum distance to be a straight line between facility point and demand point, and ignoring the distance traveled down roads. Is this possible to do, and how?  I don't need my roads, if there's a way to replace them with something else, I've just used them as that's the network I already have.  I'm trying to model sound, so the road traveled is irrelevant. Does this make sense? I attempted to make a new network, I created lines radiating out from each facility point (360 lines from each point), however I then needed to split each one as they intersected, and so far the tool hasn't finished running (been several hours so far).  I'm working with about 38000 lines pre-intersect, with many of them overlapping with a number of others.  So I'm not sure yet whether this will work. I'd appreciate any suggestions 🙂 Thanks, Mike. I'm not sure I understand your situation.  Could you simply buffer your locations to your 'as the crow flies' distance? ... View more

Hello there, I am doing some geocoding on the addresses of our program participants.  I have about 25000 addresses that I am running in batches of 2500 (anything more than that seems to crash the program before the matching is done).  when I run the geocoding addresses function, it produces the geocoded shapefile and attribute table but the window that pops up when it is done, the one with the matching statistics that allows you to match interactively is not giving correct results.  It always says zero for the % matched, % unmatched, %tied etc.  Yet, if you look in the attribute table, most of the addresses have been correctly matched.  I am able to match interactively by selecting the 'all addresses' criteria in the rematch criteria section but no matter how many addresses I manually rematch - the statistics never change!  Any ideas why this might be happening? I am very new to geocoding so maybe I am missing something obvious??? When I've run smaller sized files (<1000) I have not had this problem. any help is appreciated - cheers, Julie Oh - I am running ArcMap 9.2 and the data is stored in a dbf file prior to bringing it into ArcMap. The fact that the process bails out with more than 2500 records is a problem, and I wonder if it's a memory issue on your machine.  I routinely geocode 50,000 +- records without a problem, in 9.3.1 and was doing the same in 9.2 . The rest of your described issues are very strange as well, but I guess I don't need to tell you that.  I wonder if something is fishy with the software and you need to reinstall? Not much to go in, but I hope it helps even a little. ... View more

Hello, I have a dataset where the entire address is broken up in different columns such as house number, direction, ect.... (see attached sample of data). When I go to geocode the only options for the data are address, city, state, and zip? Is there any way to have more fields to select, or must I concatenate all the fields so they fit under the address part? I prefer not to concatenate as I think the results will be more accurate. What is the best way to geocode these addresses in this format? I've always concatenated address data; the accuracy is in your locator when it comes parsing out address components.  For example if you are matching against streets, it's always better to have Prefix, StreetName, Suffix etc in their own fields. It only takes a second to add a field to your table, call it something like, hmm.... address and then calc it with &" "& between your field names if you are still old fashioned like me and use vb. (Or really really old fashioned and use Perl, Csh, Bourne etc which I've been known to use too...) Hope this helps- ... View more

That's the only way you'll be able to do it as far as I know.  Since the order of your attributes is important, I suggest creating an empty feature class of the same type, and create the attribute table just like the one you have, but when you get to that particular attribute, make it the length you need.  Then you can use the simple data loader to load all your existing features into the new feature class. If you are working in a versioned sde environment this approach is going to s**k.  If it's a file geodatabase or a personal geodatabase it's not to painful.  Acutally, if it's a personal geodatabase, you can open the attributes table in access and change the field length there.  Nobody likes to admit you can do that, but you can; just back up your data first.... ...

Interesting- I do most of my work in CAD and some flavor Public Safety RMS myself; I'm still using 9.3.1 so any of the enhancements in 10.x are foreign to me.  I'm just curious; where do the actual lat/longs come from?  The CADs I work with assign them as long as the address is verified upon dispatch (it hits).  Of course we still dispatch if the address doesn't verify but since the CAD is (are) address-centric we don't store any history of the call since there isn't an address to assign the incident to. Perhaps we could carry on this more tangent discussion off line; jborgione at alpinegeographic dot com. ... View more
