New video series helps users deploy the ArcGIS parcel editing solution

With the release of ArcGIS 10, Esri provides users with a Land Records solution as a core part of the ArcGIS platform. This solution helps you produce great web maps, implement efficient workflows, and incorporate best practices from the land records industry at large.

The parcel maintenance solution has three key parts. First is the Parcel Editor toolbar, which is included with ArcGIS Desktop at the ArcEditor and ArcInfo license levels. This toolbar contains the tools needed to access and work with parcel data. The second part of the solution is the parcel fabric. This dataset manages the spatial and topological relationships inherent in parcel point, line, and polygon data. The third and final part of the solution is the Tax Parcel Editing map. It supports local government workflows and is a multiscale editing map that organizes the survey framework (Public Land Survey System [PLSS] and control), subdivisions, lots, tax parcels, and encumbrances in a fabric data model that can be used with the Parcel Editor toolbar.

SnowCOP Helps Local Governments Efficiently Manage Cleanup during Snowstorms

Last week, we released version 1.0 of Snow Common Operational Picture (SnowCOP). SnowCOP is an ArcGIS Server and ArcGIS Viewer for Flex application that can be used by public works, road commission, or department of transportation staff to monitor snow event responses and determine which streets (or areas within a local government) aren’t getting enough attention. It is an interactive web application that allows managers and district operations leaders to correlate citizen complaints, snowplow assignments, current vehicle locations, and planned response activities to maximize the deployment of resources when responding to the event.

ArcGIS for Local Government – The Road Ahead in 2012

As the year winds down, we wanted to take a minute to thank everyone for the participation and feedback this year. It’s been really exciting to see the user community embrace the maps and apps on the ArcGIS for Local Government resource center and provide feedback that will ultimately make these ArcGIS maps and apps better for everyone using them. The team really enjoys the ongoing dialog with our local government users and looks forward to working with each and every one of you in the near future.

In 2012, we’re excited to incorporate the functionality emerging in ArcGIS 10.1 and ArcGIS Online, along with what we learned in 2011 from you, into the ArcGIS for Local Government solution. And we’ve got some plans we’d like to share with you for 2012 that we hope will make your adoption and use of ArcGIS simpler and more successful.http://blogs.esri.com/esri/arcgis/wp-includes/js/tinymce/plugins/wordpress/img/trans.gif

Address data management just got a lot easier with ArcGIS 10

This week, we released version 1.0 of the Address Data Management Template. This template is an ArcMap editing map, editor extension, and set of editing workflows for managing road centerlines with address ranges, facilities, site addresses, and related mailing address data. It is an editor that can be used by mapping technicians in planning, public safety or land records organizations to streamline the collection, maintenance and use of authoritative address information.

When you download the template, you’ll find it includes:

  • A multi-scale ArcMap document designed for editing
  • Two Add-ins and set of constructions tools that are added to your ArcInfo or ArcEditor installation
  • The Local Government geodatabase with sample data from the City of Naperville, Illinois

The Address Data Management Template at ArcGIS 10

The Address Management Add-in and address construction tools contain a series of custom editing tools that improve the editing experience for ArcGIS users working with roads and address information.  For example, there are tools that:

  • Add new road segments and allocate existing address ranges to the new segments
  • Flip road segments to the direction of the line and address ranges are in sync
  • Add new site address points and compute the proposed address from the location along the road centerline

In addition to the tools, the Address Data Management template also includes an editor extension called the Attribute Assistant.  This extension uses a series of pre-defined methods to automatically populate attributes for you when updating and/or adding new features to the geodatabase. For example, one method will populate the full road name on each road centerline and site address feature from a valid list of road names contained in a master street name table. Other methods will help you maintain the integrity of your address data by populating a unique identifier, last editor and last update date on each feature.

The template is a great place to start if you’re looking to modernize your address data management workflows and improve the quality of address information in your organization.  It provides a configuration of ArcGIS 10 that will:

  • Allow you to manage road centerlines with address ranges, and site address points for public safety, utility, permitting and other service delivery needs
  • Associate one or more related postal addresses to a given site address
  • Implement a master street name inventory that increases the quality of your address information
  • Deploy efficient data management workflows
  • Help you implement several national address standards (NENA, USPS, etc.) that promote system integration and data sharing

The editing workflows help you improve the quality of your address information

To support the Address Data Management Template, we’ve also released an update to the ArcGIS for Local Government Information Model.  This simple, harmonized local government information model supports the maps and apps shared on the ArcGIS for Local Government Resource Center. It reflects specific application requirements and the cartographic requirements necessary to produce rich, multi-scale base maps and operational layers.   You can download the Local Government Information Model from ArcGIS.com and migrate your content into this geodatabase design.  When you do, you can quickly take advantage of the maps and apps published on the ArcGIS for Local Government Resource Center.

The latest release of the information model adds support for the address workflows contained in Address Data Management Template.  In addition, it incorporates address standards from NENA (National Emergency Number Association) and the USPS (United States Postal Service). We’ve taken these standards and implemented them where appropriate in the Local Government Information model and provided local government users with a set of streamlined workflows to maintain authoritative address information for their community.  The physical implementation of these standards supports a wide variety of system integration opportunities and is a foundation for state and national data sharing initiatives.

USPS and NENA Address Standards have been incorporated in the Information Model

Our goal is to provide local governments with a set of ArcGIS tools and workflows that simplify address management and improve the overall quality of their authoritative data.  Later this winter we’ll add a complimentary web application that can be used to enlist feedback from your citizens on the quality of your address data.  This simple web application will allow citizens to add missing site address information.  Once added, the local government can then review the new address locations and decide whether they would like to incorporate them in to their master address inventory.  In addition, this application could be used to enhance the data sources used by a Reverse 911 or other citizen engagement application in your community.

So that is a quick overview of Esri’s Address Data Management Template at ArcGIS 10.  If you’d like to see the address workflows in action, you can watch a short video we’ve posted on the Resource Center.  In the future, we’ll share blog posts on other Address Maps and Apps you can find on the ArcGIS for Local Government Resource Center.   As always, feel free to contact us if you have any questions when you begin to leverage the new address data management workflows in ArcGIS 10.

Welcome Esri Support to the ArcGIS for Local Government Team

When the ArcGIS for Local Government program began nearly three years ago with a set of maps and apps for water utilities, the user base was relatively small and the processes for receiving technical assistance with the maps and apps were still being formulated. Users with questions regarding the maps and apps typically contacted members of the local government, water utilities, land records or public safety teams themselves, either directly or through the email alias.  Team members did their best to address questions from users but with more than 50 maps and apps on the Resource Center today, and almost 50,000 downloads to date, it is difficult to meet everyone’s needs.

Today, ArcGIS for Local Government requires a support solution that can keep pace with our growing user community and deliver the assistance they need.  That solution is Esri Support.

Starting today, Esri Support should be the first place ArcGIS for Local Government users in the U.S. go with questions or technical problems related to the maps and apps provided on the Resource Center. From the Esri Support page you can access all of our online support resources like the help, knowledge base, forums, and blogs. In addition, users on software maintenance are able to contact Support by phone, email and even chat.  Once Support is contacted, a qualified Analyst will log an incident into our support system and assist the user in troubleshooting the issue until it is resolved.  Examples of possible support incidents range from problems with publishing map service, to registering an ArcGIS Add-in, or best practices for loading data in to the Local Government Information Model.

By including Esri Support as the primary contact for ArcGIS for Local Government issues, we gain several benefits, including:

  1. Greater accessibility – With Support Centers available from 5 am to 5 pm Pacific and a variety of ways to contact them, ArcGIS for Local Government users can now get their questions answered sooner and in a way that is most convenient for them.
  2. Better transparency – Any incidents logged through Support can be tracked through the My Support, as well as the Customer Care Portal, providing the user with the latest information on the progress being made to resolve the incident.
  3. Bug tracking – If a user discovers a bug (such as an error in one of the apps or problem with one of the maps) they can log it with Support and keep track of it as it is resolved.  
  4. Better self-help resources – With incidents and bugs on ArcGIS for Local Government maps and apps now being logged into our Support system, users can choose to search our Support resources themselves, often finding the answers they need without contacting a Support Analyst.
  5. Consistency – Now, when ArcGIS for Local Government team members have questions about technical aspects of the program, they can seek help from the same place they go for their other ArcGIS questions – Esri Support.

These advantages, as well as others, make Esri Support a valuable partner for the ArcGIS for Local Government team.  Of course we hope that your experience with the maps and apps is smooth and problem free. But if trouble does occur, it’s nice to know that Esri Support will be able to help you out.

We think our water utilities, public safety, land records, elections, planning, and public works users will find this support model very exciting. So, don’t hesitate to take advantage of all our available online support resources or to contact Esri Technical Support with your technical questions. As always continue to contact us directly if you’d like to learn more about ArcGIS for Local Government and the maps and apps contained in each module.

Leveraging the Parcel Fabric data structure to improve parcel map annotation workflows

Here is an interesting blog post from the Parcel Editor team for those of you who are looking to optimize your parcel editing workflows and reduce the amount of time you spend annotating your tax parcel maps.

In the parcel fabric, the parcel name text field is used to store the parcel identification number (PIN). This PIN is sometimes called APN (Assessor Parcel Number) or AIN (Assessor Identification Number) and other conventions. This number is usually kept unique by constructing it from the book, page and a sequential number, as well as similar methods. The field might store “264014001” which stands for Book 264 Page 014 Parcel 001 and can be formatted to show “264-014-001”.

Best practices include the use of label classes to show the full PIN when zoomed in and only the last 3 digits when zoomed out.

  • Label expression: to separate the parcel number by dashes you can use a label expression similar to this:  Left([Name],3) & “-” & Mid([Name],4,3) & “-” & Right([Name],3)
  • MapTips:  some users prefer to only label the last 3 digits and use a MapTip to show the parcel number when hovering over the parcel.


  • To do so, activate your MapTip in the Layer’s Display Tab.


  • To get the MapTip in the example above, use the following expression:
    ” Book: “& Left([Name],3) & vbNewLine & ” Page: “&  Mid([Name],4,3) & vbNewLine & ” APN:  ” & Right([Name],3)

Parcel Editing Workflows at ArcGIS 10 – Alley Vacations (Part 2)

Here is the second part of a blog post from the Parcel Editor Team.  Another approach to alley vacations in ArcGIS 10. 

In a previous post, we talked about how to perform a vacation of an ally or right-of-way parcel using the parcel fabric data model in conjunction with the Local Government Data Model and the Tax Parcel Editing Template from the resource center.  For this post we are going to talk about the same process, but without recreating the original lots.  As with the previous post, we will be working through an example provided by the City and County of Denver.  For this example, the lots currently in the database do not match the legal description (the lots should all be 125 X 25), which is a common occurrence in most databases.

Performing the Vacation without re-creating the original lots
Using the existing lots is the easiest and most straightforward way to go, but not the best-practice.  You could think of this as the quick-and-dirty way to get the tax parcels added and move on with your day.

1. Begin by creating a connection line for the gap between the two disconnected groups.  Use the tool on the Parcel Editor toolbar.  This ensures that a construct from parent process will work, since it requires the group to be connected.


2. Use the parcels on the northernmost part of this group, across the gap (alley).  Note the 29’ distance and 87 degree bearing.  The distance measurement should be 30’, with a bearing closer to 90 degrees.  Since we are going with the current set of lots, though, we will simply hit the Apply button to use these numbers.  


3. Select just the Tax Parcels that you need to extend to the center of the ROW (Alley) being vacated, right click and select the Construct from parent option.


4.Select the Segmented Line Tool at the top of the Parcel Details window.


Create a two part segmented line over the top of the connection line that you created.   Take note that the lines as inversed are 14.515ft, not 15.  This is due to the lots/parcels not being repaired prior to the edit.


 Note: Be careful, there are two points very close together 81 & 121 in this data.



5. Same for the southern edge, connecting the midpoints together with another boundary line, to form a centerline running down the middle of the alley/ROW.


6. Next step is to create lines across the construction lines used to re-create the ROW (Alley) and the centerline.

a. Start at point 116 as shown here and then place the cursor in the Bearing field


b. We want to extend the parcel line along the same bearing, so move the
cursor to snap to the tax parcel line that you want to pick up, hold
SHIFT and then click to pick up the bearing (this will populate that
value in Bearing field).


c. Purposely type in something longer than 14.5 (1/2 way point or ROW width)

Use the Planarize command to break the line at the centerline.  Select
the overlapping piece in the grid, right click and choose the Delete
Rows option to remove it.



7. Continue this process until all the remaining tax parcels have
been extended to the ROW (Alley) center and then merge the smaller
pieces to you existing tax parcels to get you final output.  In this
example, there are no historic ROW parcels created, since they were not
there to begin with.

Parcel Editing Workflows at ArcGIS 10 – Alley Vacations

Here is a great blog post from the Parcel Editor Team.  Its an overview of the editing workflow you’d go through to vacate an alley in ArcGIS 10.

Alley Vacation – Part 1

The parcel fabric data model lends itself to many improved workflows for managing your parcels, particularly when it is used in conjunction with the Local Government Data Model and Tax Parcel Editing Template for ArcGIS 10, which you can download from the resource center.  Some of these improved workflows are hard to detail in the help, though, so we’re hoping some blogs will help out.  One of these workflows comes from the City and County of Denver and centers on how you perform a vacation of an alley or right-of-way parcel.  The City and County are using the Local Government Data Model, which provides the ability for managing not only parcels, but also Lots and Subdivisions.

There are a few things to consider before performing an alley vacation or creating any new parcel(s). 

1. Does the alley exist in the lot layer?

If the alley exists, the first step before doing any work would be to make sure the original lot (alley) is marked appropriately in the historic layer (marked as Vacation).

2. How accurate are the measurements on the adjacent block edges/lots?

In the data that was used for this example, the lots should be 125 feet by 25 feet, but a look in the parcel description shows the measurements are off for some of the lots.



The best practice in this case is to re-enter the original blocks by cogo-ing the outer boundary of the block from recording, and then using the Parcel Division tool or Construction to recreate the lots. Once completed, these blocks can be joined to the Fabric using control points or even orthophotography.  Of course, the tax parcels would also have to either recreated from the lots or re-joined to fit the newly constructed lots.

The first workflow listed below can be used for this task.  In a later post, will talk about how to complete this process without recreating the lots.

Recreating Blocks and Lots from Records (original city subs)

1. Mark original lots historic or delete them all together from the Fabric.  In this example, I’ve left this step until the end so that I can use the lots as reference to name the new ones

2. COGO entire block boundary from record.  For this example, all of the lots are 125 X 25.

a. Create a new Plan, and give it an appropriate name.

b. Create a new construction inside that plan, set the parcel template to “lots”


 c. COGO the outer boundary like this:


Please note that the alley was divided two pieces.  More on that later.  Also note that the original lots are displayed in the background.

d. Delete the 575’ measurement


 e. Select the Segmented Line Tool from the top of the Parcel Details window:


To start, make sure you cursor is in the FROM cell of the next available row and click in the grid to replace the NW corner, type “23” to get 23 equal segments or right click.

    <img src="http://downloads.esri.com/blogs/arcgisdesktop/alley6.jpg"



f.   Click the SW corner, and do the same thing for all the other edges.

     <img src="http://downloads.esri.com/blogs/arcgisdesktop/alley7.jpg"


g.  Digitize in the connect lot lines, create a connection line for the center of the Alley.


3.  Build and Join.  For this example, the parcels are turned off and we joined directly to photography as control.  Later on, the data can be re-adjusted to proper control if desired.

<img src="http://downloads.esri.com/blogs/arcgisdesktop/alley9.jpg" target="_blank"

a. Then create any join links between the existing Parcels and the new lots…make sure to have points turned on for this!


b. Hit OK, and the data will now look like this:


4. This will make the ROW (Alley) Vacation easier since you now have the centerline of the ROW (Alley) to use to expand the tax parcels.

 a. With the Tax Parcels and just the ROW (Alley) in question selected, we can use the Construct From Parent option to do the rest of the line work.



b.  We can digitize over the connection lines, creating new lines that extend the current tax parcels.  The Planarize command can be used to get rid of any excess.  We then build to create polygons and merge the smaller vacation leftovers to the current tax parcels, carrying their attributes over to the newly expanded parcel.


c.  Finally, mark ROW (Alley) Vacated (Historic).
