I performed a simple multiring buffer around two points using the code below. This runs fine as long as the Multiringbuffer is set to "ALL"" When set to "Null" it gets the ERROR 000466 does not match the schema of target as described above. I also notice that if I have the output as a feature in a gdb instead of as a .shp it works fine. Notice that the previous poster also had his output going to a gdb and was unable to reproduce the error. This appears to be a problem associated with output in a shapefile format.

I work in a class room setting with 20 computers running windows 7. Arc Explorer desktop build 1750 was installed on all of them this week and three are unable to load the basemaps. They can however load webserver maps from Arcgis online. Any suggestions on what might be the cause is appreciated. The students are getting frustrated. ... View more

Thanks Melita for the tip, Projecting to a State plane looks a lot better. I was going to reproject after digitizing but this works better. I had also slipped a decimal point on the RMS it was 0.00005. Charlotte ... View more

I am using road intersections based on the PennDot State roads layer from ArcGIS online. (It has a GCS.) The RMS is 0.0005 which I take as being very good but the buildings are not square. Perhaps when I digitize them and and project them into a projected coordinate system they will be? ... View more

Thank you Brad for the style and for the extra explanation. I now see why it is doing it this way. I appreciate it. Charlotte Cain ... View more

The score should be lowered. In this case I am trying to teach how to find the errors and evaluate them plus how to use the geolocator. Although I think the way the zipcode is ignored is an error. You cannot assume that the address you are trying to locate is in the range of the geolocator. For instance if you were trying to geolocate participants at a local event, you could get participants from out of state thus with a valid zipcode that should not match to your locator. ...

Okay, How do I modify the style? Create a new field in my reference data for State and city and set it to zero? Charlotte ... View more

NIM055232 fixes the opposite of the issue that you are having, no matches would occur if the locator is built without all of the zone fields mapped. There is an issue where the score is higher than expected when a locator is built with not all of the zone fields mapped.  Essentially, the locator assumes that, in your case, the city and the state field have a score of 100 and the zip has a score of 0.  This increases the total score of the address and therefore can be a bit confusing. There are a couple work-arounds that we can try and use if you would like.  The first would just be to increase the minimum match score to something like 96.  Another option would be for me to provide an updated style for you in which you could build your locator from. Just let me know what works best for you and sorry for the inconvenience. Brad I am not sure I exactly understand what you are saying. When I set up the Address locator my Reference Data feature [Pittsburgh streets] did not have a field for State and City and the Field Map defaults to <none>. If I understand you correctly you are saying that because the field map is <none> it takes this as a higher value or 100 match and ignores the zip. Thus as long as there is a 5 digit zip in the zip field it will match. [Those addresses with only four digits in the zip field failed] Charlotte ... View more
