All,    I am looking for best practice for setting up my locator to handle interstate and Highway exit numbers, i.e "I-20 @ exit 465" I currently have a composite locator that is a Point Single Address and Lot and then it goes to my US Streets with City, State and Zip. And Help or suggestions would be appreciated. I am willing to create any reference data that I might need if my centerline data for the interstate and Highways is not the route to go. I don't know about best practice, but this is what I have done in the past: Freeways in urban areas:  I address them just like the local grid.  For example 4500 S I-15 SB FWY.  For my freeways, this puts the point right on the 4500 South overpass... Freeways in rural areas: use the mile markers as the basis for your address ranges.  Give yourself enough 'room' for decimal miles.  For example, I recently took a care of a short segment of freeway that goes from MM 81 through MM 112, so the address range is 810-1120.  Address 955 is at mile post 95.5 etc. Mile Posts; I'm lucky that I can get good point data for mileposts, so I use them as a point feature class like MM 293 I-15 SB FWY  or MM 9 HWY 201  etc Exits I do the same thing:  Exit 293 I-15 SB FWY or Exit 293 I-15 NB FWY.  For exits, I take the location where the off ramp diverges from the main flow. On ramps/Off ramps can be ranged 1-3, 2-4 if you need to.  That gets confusing for people other than gis-geocode people.  I work in 9-1-1 dispatch and it's a really tough sell for dispatchers to imagine four houses along an on ramp with houses 1 and 3 on one side and 2 and 4 on the other.... If you don't have a special need to address range freeways, I'd say stick to point references for everything.  You get a little leeway when it comes to locations along freeways. Hope this isn't rambling too much and you find it helpful! ... View more

Oops. Sorry about that. Your post does say source locator! I think you will need to start over but I certainly wouldn't re match everythingthing. Extract those records that don't meet your standards for a match, write them to a table and geocode them. My guess is you've probably 'fixed' a number of no-hits; no sense getting paid single time for double work! Hope this helps. ... View more

Due to some server restructuring, the source locator that I used to perform a geocode has moved. When i attempt to rematch addresses I get the following error:  "There was an error reading the geocoding information from this dataset".   The locator still exists, just in a different location. Is there a way to repoint the locator's location, or do I have to do this all over again? Try rebuilding it. I'm not sure if it'll give you the option to provide the path to the data or not. [edited moments later...] I had an old locator on my home system and moved the source data to a different directory. Then I checked the locator in ArcCatalog, and it had the dreaded red ! next to the source. All I did was re-point it and it filled in the blanks for me. I'm using 9.3.1; ymmv..... Oh, I always like to use 'relative paths' for my locators as well... ... View more

I have been trying to accomplish the same task, but can't create the composite coder.  There is no information in the error, just that it "could not complete the task".  Anyone have any ideas on weather it is something that can be done or I am still missing something? Thanks Mary Since I suggested to try it, I figured I ought to do it as well.  I just created one.  Perhaps you could detail the steps you are taking and we can trouble shoot what's going on... ...

Is it possible to set up an alias table so that all possible addresses within a range point to a single address? Example: 150 A st, Fakecity, NY 12345 If the user type 144 A st, I want the point to show at the same location that 150 A st show. Like wise if they type 149 B st (opposite side of building) should create a point at 150 A st. The way alias tables have been traditionally used is the reference data is aliased.  For example, let's say you have a segment of Main St that is AKA ESRI St; the user can type in 1234 Main St or 1234 ESRI St and get a hit. I think the way you might want to approach your issue is with a series of locators within a composite.  Depending how many of these sorts of multi-address-one-location addresses you need to deal with, you'll be spending an awful lot of time building them. Good luck- ... View more

Hello. Navteq street data includes an attribute that models dividers on a single link/arc, it is used to prevent right turns because a divider exists. check the attached image...., the left side is the real life, and the right side is how navte models it. The "Street" with the divider is modeled as a single arc with dir travel = Both  It is posible to model a restriction in the network dataset using the divider attribute?? Or we have create a polyline for each intersection to model invalid turns?, in the example it would be 4 additional turns?? I would aprreciate any help or insights from you experts.... Thanks Had to take a second look at your images; obviously, you're not in the U.S.!  😮 Anyway, I'm not at all familiar with Navtech data, but could you augment it with an additional line that has a one way restriction to the correct direction of travel? ...

Can anyone tell me how to go about geolocating photos? I have a lot of photos taken with Ricoh and Terrasynch (Trimble) software that have gps coordinates embedded in their properties. I can't find a way to have them automatically located in a map. Have created shape files with a Photo field and have the address links in the Photo field for the photos but don't know how to get them to geolocate. Any help would be greatly appreciated. Sincerely, Edi Can you elaborate on the shapefile you created? My guess is it's a point feature class that is derived from the 'gps coordinates embedded' in the photos themselves? It sounds like you want the image to symbolize the feature class, right? In past, using photos/images have been with hyperlinks where you mouse click on the point and the image appears in a second window.  If my interpretation is correct, it'll be a fairly complex procedure since you are dealing with several variables; anchor point, image size, etc.... ...

Hi Joe and thanks for your reply, I have no experience whatsoever of working with turn feature classes and from what I just checked on the documentation it doesn't seem that straightforward to me. Can you tell me a bit more what it would entail? Do you really think that it is simpler than finding the proper way to have a function in the evaluator that connects to a field? Thanks You're right, they aren't that straight forward, but once you figure them out, they work very well.  Basically, you are creating a set of lines that you assign an impedance to.  There isn't enough space here nor do I have the time to describe the process fully; there are several online resources though available.  Use your favorite search engine on 'creating turn features' and see what you find.  There are several posts to this forum on the subject as well; here's one. Friend and Colleague Mike Price at ESRi has written several excellent articles in ArcUser magazine as well: here's one. And another. Hope this helps- ... View more

I have built a custom cost evaluator in my network data. One aspect of it relates to edges and I have no problem with that. I would now like to complicate it and add a component of the cost linked to junctions. If, in the evaluators window, for that attribute and in the line that corresponds to junctions (the 3rd one) I add a constant value for junctions, I have the behaviour I want. However, rather than a constant I would like this cost to be the value of a field which I plan to add to my junctions table (the table associated with the layer whose name ends with ND_junctions).  The "Field" type of evaluator is not available for the junction. Therefore I have tried going round this with the "VB script" type of evaluator but I failed miserably. Could you let me know how I would set the cost for junctions to be field "F" in my table xxx_ND_junctions? Thank you Couldn't you do the same thing with a turn feature class?  Even a 'straight' turn can be modeled that way... ... View more

Hi all, Im new to Geocoding and I'm using ArcGIS10 (ArcInfo license).  I have a spread sheet of point locations, but some are listed by address and some by intersection.  Further, some of these addresses and intersections have spatial operators.  For example, the point is "32 feet North from 4300 McGlothen Way", or the point is "250 feet East from Snowden Ave @ Ganges Ct". So, I have questions as to how to set up my excel table to properly represent this information, so that it will import correctly and geocode the points.  So far, my headings are:  SITE_NUM (which is an ID), FACILITIES (which is a name), ADDRESS, INTERSECTION, SPATIAL OPERATOR, CITY, STATE, ZIP 1. Should I have separate headings for Address and Intersection, or can I put an intersection in as an Address? 2. Is SPATIAL OPERATOR an acceptable field?  How do I populate it so that the address/intersection point location will be moved the correct amount of feet in the correct direction?  Right now each record looks similar to this: "250 feet East from Snowden Ave @ Ganges Ct". 3. To further complicate things, some of these point locations are just Place Names.  Do I need to create a separate spreadsheet and address locator for these? Answers to any or all of these questions would be greatly apppreciated.  I thank you in advance for your time and much needed help. Christi Nelson First and foremost; if you are going to use excel, be sure you don't have any spaces or special characters in the field names.  For example, if you want to use Spatial Operator, rename it to Spatial_Operator or SpatialOperator or something along those lines. As far as your specific questions: 1.  You can use the address or an intersection to geo-locate a point, so long as the address is standardized to the data you are matching against, AND, you use the proper symbol indicating an intersection; typically these include &, AND etc. 2. I would drop the the 'spatial operator' concept.  If you are geocoding against street centerline data, you results are interpolated anyway.  In other words you are going to introduce a certain amount of precision error.  Think about this; if a street has a range of 100-200 on the even side, and 101-199 on the odd side, any geocoding locator is going to interpolate the address 150 half way on the block and on the even side.  It may be that house 150 is at one end or the other.  If you require the level of precision that your 'spatial operator' implies, you'll need to find a more reliable method. 3.  Geocoding is a translator of sorts.  It takes something that us humans know, like 1234 S Main St and turns it into an X,Y coordinate pair that a GIS understands.  You can create a locator that works with Place Names, but you'll need to provide the X,Y for each.  A locator of that type matches against a point feature class where the X,Y of the Place Name is known. Take a look at the online help for geocoding, starting here. Hope this helps- ... View more

Hi again Jay, So essentially I need a shapefile of points, and a shapefile of lines, and then follow the network analyst tutorial here? http://help.arcgis.com/en/arcgisdesktop/10.0/pdf/network-analyst-tutorial.pdf (I realise I'm simplifying alot!) James Not to steal Jay's thunder, but yeah, that's about right.  I googled London Underground Shapefiles and found a download of the station locations (no .prj file though) Haven't come across the actual 'tubes' as they are known. ...

I�??m trying to do this now, and I am concatenating, problem is that not all the fields have values and I end up with leading/trailing spaces or double spaces.  How can I get it to concatenate but skip over the empty fields? Small sample set attached. That's a pretty common problem.  There are several approaches you can take: Perform a selection such that all the elements are present and concatenate all those list, and then perform subsequent selections (and subsequent concatenations) that 'weed out' those address elements that are <null> or blank. or Just perform the concatenation process on all records regardless of individual column content, and then go back and search and replace for double spaces or leading spaces.  I don't think trailing spaces will give you a problem when geocoding. or In the field calculator, use the advanced setting and build a series of conditional statements that take care of empty field contents. Whatever you do, I suggest that you import the data to a table in some flavor of a geodatabase and leave Excel to the accountants. ... View more

Often times error messages are pretty vague. These seem pretty specific. Go to any of the locations listed in the error and with the network inspection tool poke around and see if there are any problems with connectvity. If an element is non-traversable there is a reason for it. Does it have a barrier? Is it restricted due to an evaluator? Is it disconnected from the network? You might also make sure that your taz centroids are within the specified tolerance to be considered as a network element. Hope this helps- ... View more

Hello, I'm new to NA and trying to figure out if the following is possible: I've got a network dataset of toll roads and I want to generate a route between an entry and exit point and then generate a list of toll plazas and their associated tolls along the route. I'm having no problem setting the toll plazas as cost barriers, generating the route and getting the accumulated toll but is there a way to get a list of barriers encountered along the route? Ultimately I'll be accessing this as an ArcGIS Server service from Silverlight. There is a Barriers property returned by the RouteTask but it appears to be every barrier in the layer. Is the only way to retrieve a list of barriers to do a separate spatial query? Thanks! Jill Your barriers are a feature class right?  Can't you just select the current route and then do a spatial selection based of the barriers/tolls based on proximity to the current route? (Can't help you with silver light althought there is a guy lurking out there that probably can.  Alexey are you reading this?!) ... View more
