Address Data Management; Site address numbering

ChrisMartinez

I'm testing the Address Data Management solution and plan to deploy it as soon as I have a solid grasp. The issue I'm having currently is with the Full Address Number that is auto generated in one of several different ways. No matter which method I use, the generated numbers are not in line with the actual numbers. Which means this isn't much of a timesaver if I have to go back and edit each one after I create it.

I've tried using the Offset on Left/Right Side of Road and the Address Line Method. The first address I create is generally two to four digits above what I have as my first From Address on my center line. Then gets progressively more out of sync as I go along. Is there anything I can do to make the numbers match up better?

Respectfully,

Chris M.

@ChrisFox,

I am trying to retrofit this attribute rule into an existing geodatabase and am having an issue recreating the Address Line rule. Currently I get an error using the expression as-is: "Geometry cannot have Z values". This is on a feature class that does not have Z-enabled. I have tried removing the "z":0 code from line 122 but still get the same result. Does the SiteAddressPoint feature class have to be z-enabled for the rule to work?

Chris Fox

Hi @ChrisMartinez,

Yes, that is exactly how I would approach it. I tried this out and was able to update the rule below to handle this exact scenario. I added a new field called startnum to the AddressLine feature class and exposed it in the editing template for the layer. Then using the updated code below it behaved exactly as you described, if you leave it blank it will use the original logic, otherwise it will use the number you specify for the 1st address point and then increment by the value you specify after that.

// This rule will create one or more site addresses at each vertex along a line
// The first vertex must intersect a road and is used to determine the initial address of the first site address point (2nd vertex). The 2nd vertex is also used to determine the side of the road the addresses fall on. Each additional vertex in the line will create a site address point and the address number will increment by the value passed in the feature template.
// A new address point will also be added for each new site address point located at the closest point to the site address along the road

@bbaker_tngeo, my best guess is your Address Line feature class is z-enabled. The rule takes the geometry from the vertices of the line sketch to create the site address points and if the line feature class is z-enabled then the vertices geometry will have a z value. Since this feature class is just used for sketching and only has one rule, the easiest fix would probably be to delete it and recreate it without z values enabled.

@ChrisFox,

That worked perfectly. I may have grasped the logic, but tinkering with the code would have taken me a while. Thank you so much for the assist!

Thank you. I understand that it's important to ship the solution so that it will cover as many use cases as possible. Sadly because of numerous factors we are something of a petri dish for edge cases and as such I'm just looking to tighten up the numbering so I don't have to go back and edit 90% of the addresses I just created.

Using the Address Line method you mentioned, does get me closer. It would be great if I could feed the tool a start value similar to the Sequential Numbering tool. That way when an inconsistency comes up, I can end my sketch and pick back up on a number of my choosing. In order to accomplish this, it seems I could add a new field (myaddrnum) to the address line table so I can expose it for editing, then change the necessary code to test: If(myaddrnum != null) use that as the start value of the second vertex and increment, else grab the number from the road centerline and do as you normally do.

Does that seem doable, or is there a lot more to this that I've yet to see?

Respectfully,

Chris M.

Hi @ChrisMartinez,

The methods for constructing new Site Addresses don't consider the address numbers of other Site Addresses when placing new addresses. The logic uses the address range of the road and the distance along the road where the address point is placed to determine the address number. So if the road has a range of 101 to 199 and the address is placed around half way it will get an address number of 149.

Additionally, with the Address Line Method, you have the ability to specify the value addresses should increment by, so if you specify 4, the first site address point will get an address number using the logic above and every site address point you place after that will increment by 4.

Based on what you describe It sounds like the address range of the road may not accurately reflect the correct address numbers along the road. Some communities calculate the address range of the road based on the length of the road and a defined distance between address numbers. We include a disabled rule on the Road Centerlines called Logical Block Addressing. In this rule you can define the interval or distance between unique addresses and when the rule is enabled when you define the left from and right from address number on a road it will automatically calculate the correct left to and right to values based on this interval and the length of the road. You just need to customize the addressIntervalDistance shown below to meet your community's requirements.

// This rule will calculate the left to and right to address number using the left from and right from address numbers, the length of the road and an interval or distance between unique addresses
// This rule is disabled by default. It can be configured by updating the addressIntervalDistance and unit variables below. Enable the rule when you are ready for it to run as the road left and right from values are updated.

// Specify the interval or distance between unique addresses
var addressIntervalDistance = 50;

// Specify the unity of measure. Valid options are feet, meters, yards, miles, kilometers
var unit = "feet";
