I think it depends on how you score a match. In the limited experience Ive had with composites, I set the score at 100%.  That way it's either a hit or not. It makes sense to me that if you are okay with a match scoring less than 100% that both might return partial hits. ... View more

Well, I just added a published locator service to a 9.3 ArcMap session using the geocoding tool bar and everything works.  Don't know why it doesn't work for you. ... View more

I keep hearing all these great things about ArcGis 10.x and geocoding.  Gotta give it a try some time... All serious aside, unless things have radically changed in 10.x from 9.3.x and earlier, you should be able to access the locator from ArcCatalog or ArcMap.  Take a look at this link for ArcCatalog connections.  It's pretty straight forward. In the good old days of ArcMap 9.3 (which is where I live, work and play) one simply goes to the Tools menu, and selects Geocoding/Address Locator Manager.  Then use the add button to navigate to the connection you've already set up in ArcCatalog. See attached image. Hope this helps. ... View more

I need roads that were built last month. Well... I'll settle for roads with homes receiving mail. Yeah, everybody wants them and wants them for free.  Good luck with that.  For Utah you can check the state's Automated Geographic Reference Center. ... View more

I'm not suggesting to look at each record, just the field names of the address table.  However, you may also want to look for <null> values within the actual records. I don't like using spreadsheets for address tables; I'd rather upload them into some flavour of geodatabase.  The select tool is good for listing all the values in any field including <null>; you let the machine do the work, right?! ...

My comments in bold.... I created a geocoding engine from census edge shapefiles. How can I update with new streets? Your locator points to a feature class of streets; if you edit that feature class, and you want the changes to be recognized by your locator, right click on the appropriate locator icon in arc catalog and select rebuild. Where can I find updated data? How far is up?:rolleyes:  What region are you looking for? Have you tried local governments like city, county or state gis providers?  Isn't there some streets data that ships with ArcGIS software? How current are your census edges?  have you tried to get more current data from them? Hope this helps- ... View more

Take a look at the field names in the spreadsheet.  If there are any special characters or spaces in the field names it'll choke. ... View more

I get the same (lack of) performance as you do Dan.  It doesn't seem to want to hang on to the field mapping.  As soon as I close that field, and then reopen it, they are gone... ... View more

Dan-  saw your reply on the general forum.  I guess I'm lucky that I only deal with one locator at a time, but interesting to know you can batch process locators. I may give a go just to see how/if it works for me. Hopefully someone here can answer your question; there are a couple of ESRI folks lurking out there in the cloud that could probably take care of you. ... View more

Personally, I wouldn't user the tool, I'd just go through the tutorial listed here.  Basically what you need is a feature class to match against, typically street centerlines that have address ranges and street names.  Depepnding on how that data is set up is how you'll go about creating a locator.  The easiest locator to use (assuming you are in the U.S. and you have street centerline data) is the U.S Streets type. Your table of addresses will have to follow the same standardization as the data you are matching against.  For example, there will need to be a field called ADDRESS and it should contain the address info that will work against your data.  It should look like 1234 Main ST, or 1234 S Money Grubbing LN.  Notice that one address has a prefix directional and the other does not.  They both have street Sufix types and those are standarized.  How is your data set up? Do you use pre-directionals?  If you do, are spelled out or simply N E W S?  Or are is it No sometimes and N other times and NORTH still other times?  If you have a type, is it Street or ST or STR or??  That's what I mean about standarization. Give the tutorial a spin and if you are still lost, post something back up here.  You can email me at my first intitial, lastname at companyname.com shown below. Hope this helps- ... View more

These look a lot like Utah addresses.  Some counties like Salt Lake have rules about numbered streets; they end in 0 or 5.  I suppose you could parse out your address string and then examine the second numeric string to see if it's divisible by 5 (modulus function) and make an assumption that if it is, then it is the street, whereas if it is not, then you'd want to swap the the two elements before you stick them back together as the address string.  There is always a certain risk in making assumptions however... ...

My response(s) in bold Thank you for the quick response Joe.  I just wanted to make sure I understand correctly what you are recommending that I could do to address this issue.  For the ones which are 100 percent matched, but tied, I could take a sample and verify that they do in fact lie within the same tract.  However, I understand that the partial matches may be much more of a problem, if the two candidates are matched at 78 it is more likely that they are in very different locations.  Look at two addresses: 1234 S Main ST and 1234 N Main St.  Toss out the pre-directions and they are an exact match. That's why partial hits can be problematic. Is it possible then to have Arc count them as matched if there score is 100 but unmatched if it is any less (if I find that I am comfortable with the 100 percent matches)? Absolutely; when you create your locator you can adjust what scores can be a match or a miss.  You can also score ties as a miss if you like. Secondly, is there anything known about how Arc chooses 1 of the tied candidates as the match address? Is this process random? Or is it determined by the layout of the line file? It occurred to me if it were random, it is likely to be less of an issue, however if it just chooses the first one it comes across it may be biased in some way. Any insight into this process would be greatly appreciated. I've never really thought about that way; typically I view ties as a problem in the data I'm matching against and go in and fix the problem.  If two addresses match against two separate streets, that means the ranges overlap, and I like to fix those. Thanks again for all the help!  Cheers. Good luck ... View more

I don't know of any literature cititations to reccomend, however, just for fun you maight make some random checks on your ties and see if the tied addresses are not in different tracts.  You'll need to decide what a significant sample of that would be. Also, I think your partial hits might be more of a problem.  Let's say you have an incident logged as 1234 S Main St  and you get a partial match at 1234 N Main ST because S Main ST is now called  S Old Main St but the LEO still calls it S MAIN ST.  You may want to take a look at your partial hits; working in 9-1-1, I always look carefully at those that match but less than 100%.  Obviously that's not a practical standard for the numbers of records you are dealing with. Hope this helps- ... View more
