I am preparing to add address ranges to a street centerline dataset for use with geocoding. It seems having separate start and end values for left and right segments is the preferred method. I am confused at how these left and right values are determined. How do I know if I am apply the range to the correct side? I couldn't find this information in the geocoding help section (9.3, although I may have access to 10.1 if necessary). To put it another way, how does the ArcGIS geocoding process interpret "right" and "left" Naturally, I want to make sure my hits are placed on the correct side of the street... Typically, address ranges follow the direction of the line as defined by the from node (green) and the to node (red).  Consequently the right side and left side is defined with respect to the direction of the line.

Thanks for your reply. This is a very new area to me so the terminology goes over my head a little. I have an SQL 2005 database and  have managed to find the longitude and latitude for the 10,000 property records i have, those are stored in fields called "longitude" and "latitude". I was going to use JavaScript and the Google API to plot the results once i had found the properties in the radius I am searching. I was hoping i could take my starting properties long and lat and from there do a few JavaScript functions to calculate the miles/degrees to search in my SQL database, return the properties within x amount of degrees east to west and the same north to south. With those results  push them to the Google API and i have all my results pinpointed. Does that sound possible? Thanks again. I suppose so. Knock yourself out..... ... View more

Hi, I have a database of properties in the UK and each property has a longitude and latitude assigned to it. What I am trying to do is find out how many other properties are within a certain radius (in miles or kilometers) of a single property that is selected. The question is, if I have a longitude of 53.915100 and latitude of -1.945800 for example. And I wanted to find other properties in a 5 miles radius of this one, is there a simple calculation I can do to measure 2.5 miles either side of the longitude and 2.5 miles either side of the latitude? Many thanks for looking. Hopefully someone out there has had to do this 🙂 When you say you have the properties in a database, what type of database? Have you added the points as an event layer and then saved them as a point feature class? Once you have a set of actual points in your GIS, you could buffer a single point and perform a spatial selection or you could use the near command.  I think you could also create a graphic circle centered on your XY pair and select those points within the graphic... ...

Thanks for that. With domains I thought that just creates a list which is not much help as I am typing in many different things into the boxes that wouldn't be in the list. I do however use domains on other fields. Thinking about it, how does one add null to a domain. Surely typing in null or <null> would produce characters rather than null itself. I think what I did is set it to 'Allow NULL Values' = YES for the field. And then assigned the domain to the field.  That may not be helpful with you since your database is already set up.  The thing about domains is you can always calc a value of your choice; if working on a single record it provides a pick list to choose from, but you don't have to select the choice. You can enter in what you want, as long as it 'fits'; that is if you have a 2 character field, obviously a 10 character value won't fit..... With respect to your original post, the key might be allowing null values; it's been a while since I set that database up and I just don't recall. Hope this helps- ... View more

Okay; now I think I see what you mean. Can you use a domain where <null> value is one of the choices?  I have a couple text fields set up that way. ... View more

Brent-  given what I saw in the original data, you're doing better than I thought you would. I was thinking along the same lines as what Robert mentioned; if your cut off values are too low, you could be shutting down before you really want to. ... View more

I am trying to run a closest facility analysis but routes are only being calculated for 4 of my 54 incidences.  For the remaining 50 incidences I get... �??Warning: No "Facilities" found for "XXX" in "Incidents"�?�.  It looks like the routes are not making turns at any junctions. I have found that a connectivity issue is usually the case, but I have created a network dataset from the New Jersey Roadway network http://www.state.nj.us/transportation/gis/data.shtm and it looks like the network is connected and it comes up with junctions at every interest when the network dataset is created.  I have also snapped the facilities and incidences to the network. The only attribute I have in my network dataset is �??length�?� as a cost because I am only concerned with the distance traveled when determining a route. I have had the connectivity policy set to any vertex and end point, and neither has worked. Any help would be appreciated. Thanks, Brent I just downloaded the shapefile, imported it into my own pgdb and then clipped out a dense area on the east side of the state. (Not familiar with NJ, so I don't know the town). Looks like there are some major connectivity issues to me.  Or should I say lack there of.  See the attached screen shot.  For each of the selected streets, I only 'clicked' on one end to select it.  Shouldn't there should be intersections along the way? Try to create a service area by just interactively dropping a 'facility' around the state and see what you come up with.  My guess is you'll see a lot of what I show here. ... View more

Here's some free advice: you get what you pay for... Seriously, SDE and Server are not trivial technologies.  I took an SDE management course from ESRI back when the current version was 8.x and have been using the technologies ever since.  Been learning them all along the way as well. Do yourself a favor and check with ESRI online courses or instructor led courses.  It's money well spent. ... View more

Hello everyone.  I'm trying to geocode about 3000 addresses from a CSV file using ArcGIS 10.0 SP3.  I have tried using the following ArcGIS server link: http://tasks.arcgisonline.com/arcgis/services/Locators/TA_Address_NA.GeocodeServer When I run the following python script I get an error after about 10-15 minuntes.  Seems like sometimes it works, others it doesn't without changing anything. arcgisscripting.ExecuteError: ERROR 000010: Geocode addresses failed. Failed to execute (GeocodeAddresses). Is it a timeout issue?  I have noticed when the network traffic at my location is slower it works fine.  Still takes a while though.  Should I be using a local locator?  If so, which one.  I'm not very familiar with these locators.  Tried to create one but kinda got lost.  Other tips to speed it up?  Can anyone help me out? Thanks Can't help much with the ArcGISOnline thing; I suppose you have a paid subscription?  Without one I dn't think you can do batch geocoding. Personally I shy away from CSV files when performing any sort of geoprocessing.  I like to use real-live database tables of addresses.  I also prefer local locators since I have control over the data.  Choosing a locator style depends on the data you have access to as well as the format of your addresses. You may want to start here to gain a little more knowledge of the subject. ... View more

Just know that you'll have 'false positives' when it comes to cul de sac streets.  In other words, your topology will report more errors than you truly have. ... View more

Hi, I have recently got a new PC so went to re-install Network Analyst. I have ArcGIS 9.2 and I have the Network Analyst extension, I ran the user license and it gave me the authorization message. I then expected it to be in the extensions (Tools>Extensions) but it's not. I have a project set up already which has an ITN layer etc, and I added in the Network Analyst toolbox and tried to run some of the stuff in there but it says i dont have the required license (Network Analyst). Any idea's what I am missing? When you ran the install, did you do a standard installation?  It should have installed all the extensions.  Tack a look in your c:\programfiles\arcgis\bin directory and see if you have any of the Network Analyst dll's. Just an fyi, my guess is 9.2 is nearing the end of it product life cycle, so support will begin to dry up. ... View more
