Geocoding Results Spatially Off

DavidBuehler — Wed, 27 Nov 2019 15:29:59 GMT

I created a locator in Pro using the "Create Address Locator" geoprocessing tool. It was a "US Address - Single House Subaddress". Then I ran the "Geocode Addresses" geogprocessing tool against a table of addresses, using the preferred location type of address location, and checked the categories.

What I am seeing is the geocoder has matched all of addresses in the table with almost 100% certainty. However spatially the results are off from the actual point. The results are any where from .3' to a foot and half off.

I have checked the data from the source and the map are in the same projection.

I am a loss. Should they not line up exactly?

Given the season, my first thought is you have a lot to be thankful for...

I guess in theory they should be, but that level of precision would be more than good enough for me...

It is just odd that it should line up with an existing feature, but it does not. Nothing to lose sleep over, so I am moving on.

David:

This happens with our locators as well. Did you ever find an explanation?

Hi. Having similar issue. Using the Pro 3.3 modelbuilder Geocode Addresses tool, I get results that are off by up to 100 ft or more. If I use the ArcGIS Pro 3.3 Locate tool, the first result is correct, but geocoding using the same locator and addresses gives a different result. Unfortunaly this case doesn't allow my results to be good enough. Has anyone found a solution? Thanks in advance.

No. No one ever responded to my question. Still very curious about it though.

I opened a case w/ ESRI (#03661884). I was able to change the settings of the locator to get the desired results. Here are some notes from my case. Hopefully this is helpful for you too.

Original issue: The geocoded points do not fall over the reference data and has an offset ranging from 0.5 feet to 1.5 feet to in ArcGIS Pro.
Created a new locator using the "Create Locator tool" with the following parameters:

Country or Region: United States
Primary Table(s): E911Address_Points_Current_Cranston; Role: Point Address
Field Mapping: House Number: Address_Number; Street Name: Street_Name; Suffix Type: Street_Type_Suffix; Full Street Name: Full_StreetName; State: State
Optional parameters: Precision Type- Local Extra High.

The default precision type "Global High" has a precision of approximately 0.5 meter, which is consistent globally. Hence, we were getting an offset in the Geocoded result. Instead use Precision Type- Local Extra High.
Match with no Zones = 'Yes' and comprehensive zone matching = ‘No’ in the Geocoding options
Geocoded the "LocatorTest_E911PtsTable" with the newly created Point Locator, and the output feature layer did not have any offset and was lying on top of the original points.
