Oahu User Group Meeting


Thanks to Steve Lettau, Oahu User Group Coordinator, for arranging this meeting at Kamehameha Schools. KS was one of the early adopters of GIS in Hawaii back in the early 1990s. The user group meeting is open to the public. I checked, there still some seats available, so RSVP if you'd like to attend.

Hawaii County GIS Resources - Address Data




I'm spending this week on Big Island working with county staff who use GIS in their work.  I've compiled some links to online resources that we'll be using during the week and since they may have broader interest, I'm sharing them here.

In a post on general resources, I provided information and links on:
  - Upcoming Events
  - ArcGIS for Desktop: Data Driven Pages
  - ArcGIS for Desktop: Editing
  - ArcGIS for Desktop: Miscellaneous
  - ArcGIS Online
  - LGIM: Local Government Information Models

In an another post I provide information and links on parcel (TMK) data.

In this post I'll cover another fundamental GIS layer in local government - the address layer.

Hawaii County GIS Resources - Parcel (TMK) Data




I'm spending this week on Big Island working with county staff who use GIS in their work.  I've compiled some links to online resources that we'll be using during the week and since they may have broader interest, I'm sharing them here.

In a post on general resources, I provided information and links on:
  - Upcoming Events
  - ArcGIS for Desktop: Data Driven Pages
  - ArcGIS for Desktop: Editing
  - ArcGIS for Desktop: Miscellaneous
  - ArcGIS Online
  - LGIM: Local Government Information Models

In an another post I provide information and links on address data.

In this post I'll cover one of the fundamental GIS layers in local government - the parcel layer.

COUNTY REAL PROPERTY MAPS AND INFORMATION (TMK DATA)

The County of Hawaii Real Property Tax Division maintains maps and data describing land parcels in the County. This is often called the TMK (Tax Map Key) data after the unique tax map key number assigned to every property. Each TMK has nine digits (ie: 322012004) assigned as 'dzspppnnn' where:

   d = the Division: Hawaii County is always 3
   z = the Zone: Hawaii County has nine zones (see map to the left)
   s = the Section: each zone is divided into nine sections
   ppp = the Plat: each section is divided into plats
   nnn = the Parcel number within a plat

Division, Zone, Section, Plat (three digits) and Parcel (three digits) are combined to create a unique TMK number for every parcel in the County. In my example, 322012004, the division is 3, the zone is 2, the section is 2, the plat is 12 and the parcel is 4. Note the use of leading zeros for the plat and parcel numbers.

Some parcels have taxable units within the parcel. Sometimes these are condos, sometimes agricultural lots, sometimes for other reasons. These CPR or HPR numbers, if they exist, add four more digits on to the right side of the TMK, creating a thirteen digit full TMK. There are none for the example parcel, so its full TMK is 3220120040000.

Real Property Links

Here are some useful links to find Hawaii County Real Property maps and information:

Searchable data: Ownership, sales, permit and other information can be searched for by TMK or by Address at:
http://www.hawaiipropertytax.com/Main/Home.aspx

Plat maps: Parcel maps are organized by plats, there is a separate map sheet (plat map) for every plat in the County. Each plat map sheet has been scanned and is available online. Here's the link:
http://www.hawaiicounty.gov/real-property-tmk-maps/

Subdivision maps: Plat map sheets compile information from one or more subdivision maps. The individual subdivision maps are also available online. Here's the link:
http://www.hawaiicounty.gov/subdivision-maps/

A few notes:

- The Division is the same for the entire County (3) and it is left off of the TMK in some databases, leaving an eight digit TMK. While this works within a single county, it does not work for statewide TMK databases.

- In some databases, the TMK is written with dashes and a colon to make it easier for people to read, and often the Division is dropped, so you'll see 'z-s-ppp:nnn' for the TMK.  This can wreak havoc when relating different tables by TMK, be careful!

For more examples of how TMK data can be used in GIS, you can read my Hawaii GeoTeam 2013 blog on TMK data in GIS.

LGIM FOR LAND RECORDS

There are maps and apps that work with the LGIM for Land Records.  

Hawaii County GIS Resources - General




I'm spending this week on Big Island working with county staff who use GIS in their work.  I've compiled some links to online resources that we'll be using during the week and since they may have broader interest, I'm sharing general information here.

In other posts I provide specific information and links on:

UPCOMING EVENTS

First, a few upcoming events including a couple of online classes:

Aug 20-22, 2013   Online Class: ArcGIS for Server: Site Configuration and Administration (10.1)
Aug 27-29, 2013   Online Class: Configuring and Managing the Multiuser Geodatabase (10.1)
Sep 18-20, 2013   Conference: HCPO Hawaii Congress of Planning Officials (Kailua-Kona, Hawaii)


ARCGIS FOR DESKTOP: DATA DRIVEN PAGES (MAP BOOKS)

There used to be an extension in ArcGIS for Desktop called "DS Mapbook". It was a great little extension that provided tools to help you create a map book. At ArcGIS 10.0 (and 10.1 and 10.2) similar tools are part of the core product on the Data Driven Pages toolbar.

I posted on the Hawaii GeoTeam 2013 blog about election data including an introduction to Data Driven Pages.  Here's the link:
http://geoteam2013.blogspot.com/2013/06/show-tell-for-module-8-election-data.html

There's a 70 minute video from Esri UC 2013 demonstrating how to use Data Driven Pages and how to customize map books using Python scripts.  Here's the link:

ArcGIS Skills for Hawaii

Do you want to learn ArcGIS for Desktop GIS Software?


I teach a night class for the PCATT program at Honolulu Community College that introduces students to ArcGIS for Desktop using Esri's Virtual Campus supplemented with additional Hawaii-specific "Show & Tell" information and "Challenges".

This summer (2013) I'm working on a GIS project with several students from Maui and the Big Island - Hawaii GeoTeam 2013 - and they needed to learn ArcGIS for Desktop. Since we're working remotely, I've moved a lot of my "Show & Tell" and "Challenge" content to a GeoTeam 2013 blog.

Special thanks to Alex, Jeremie, Josiah and Lotus for working on this project and helping me test the online content, and to Bill and Ria for giving me the idea to make the materials available to others.

You're welcome to use these materials to support your own self-study. You'll need to purchase the online class "Learning ArcGIS Desktop (for ArcGIS 10)". If you don't have the ArcGIS for Desktop software, you can request a copy after you register.

The online class was prepared with Desktop version 10.0 but works just fine with version 10.1. I've posted some notes where there are differences.

There are three types of blog entries: notes, show & tell and challenges.

   - Notes are used to show where version 10.0 and 10.1 are different

   - Show & Tells are used to give materials that supplement what you've learned in the online class modules.

   - Challenges are used for you to practice what you have learned using Hawaii examples.

Here are the blog entries, in order, to go with the eight modules in the online class. Modules 1 thru 4 are treated as a unit.

Modules 1 - 4 (Introduction to GIS, Features and Attributes)

   Notes on differences between 10.0 and 10.1

   Quiz

   Answers to Quiz

   Show & Tell for Modules

   Challenge for Modules

Module 5 (Editing)

DOH Flu Vaccinations Sites - Embedded Map Example

Here's a blog post for web designers on how a web map can be embedded in a web page and then linked to a mapping application.

Muggle Warning - HTML code will be used in this blog

For this example I'm going to use a web map and a mapping application used by the Hawaii State Department of Health to show flu vaccination sites.  Here are the web IDs for the two items:

   web map ID:                 webmap=cda25f51ce994443a592011ecec15e03

   mapping application ID:   appid=8d6af87ca1f249878b2e6beb9a38ebec

Starting in the web map editor on ArcGIS Online, you click the "Share" button and then click the "Embed in Website" button. That opens up a window to configure the embedded web map.

You can use the radio buttons to configure the tools that will be available on the embedded web map.

As you turn various tools on and off, the code in the HTML window will change accordingly.

For example, here you can see I've turned on the zoom control, legend, description and search tools.

I've also set the size to 500 x 400 pixels and added a link to "View Larger Map".

When you're finished configuring your embedded web map, you can copy the code in the HTML window and paste it into your web page.

Here's the web map for flu vaccination sites embedded into this web page using the configuration example above (modified as described below):


View Larger Map

This is a live map, the user can pan, zoom, search and click on a star for more information.

But there's one further modification you can do. By default, the "View Larger Map" link opens the web map in the web map editor. It is usually better to open the web map in a mapping application. You can do this by changing the HREF link that you copied from the HTML window.

Let's deconstruct the code from the HTML window and you'll see what I mean. Here's the code split into sections:

1) set up the iframe size and other parameters:
<iframe width="500" height="400" frameborder="0" scrolling="no" marginheight="0" marginwidth="0"
2) use the embed template from ArcGIS Online:
src="http://histategis.maps.arcgis.com/home/webmap/templates/OnePane/basicviewer/embed.html?
3) put the flu vaccination sites web map inside the template:
webmap=cda25f51ce994443a592011ecec15e03
4) open the map at an extent that shows the eight main Hawaiian islands:
&amp;gcsextent=-160.3411,18.6238,-154.6612,22.7594
5) add the tools selcted during configuration:
&amp;displayslider=true&amp;displaylegend=true&amp;displaydetails=true&amp;displaysearch=true">
6) close the iframe that contains the embedded map:
</iframe>
7) start on a new line and make the font smaller:
<br /><small>
8) use the viewer template from ArcGIS Online:
<a href="http://histategis.maps.arcgis.com/home/webmap/viewer.html?
9) put the flu vaccination sites web map inside the template
webmap=cda25f51ce994443a592011ecec15e03
10) open the map at an extent that shows the eight main Hawaiian islands:
&amp;extent=-160.3411,18.6238,-154.6612,22.7594" 
11) set the color of the text and set it to open in a new window:
style="color:#0000FF;text-align:left" target="_blank">
12) show the text and close the hyperlink and set the font back to what it was
View Larger Map</a></small>

To change the "View Larger Map" hyperlink to open a mapping application, you need to change parts 8 - 10 as follows:

8) change from the viewer template to the OnePane basicviewer app template:
<a href="http://histategis.maps.arcgis.com/apps/OnePane/basicviewer/index.html?
9) change the template contents to the app:
appid=8d6af87ca1f249878b2e6beb9a38ebec
10) and you don't need the extent at all (the app knows the extent) but keep the close quote:
&amp;extent=-160.3411,18.6238,-154.6612,22.7594

So now the HTML text to copy and paste looks like:

<iframe width="500" height="400" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://histategis.maps.arcgis.com/home/webmap/templates/OnePane/basicviewer/embed.html?webmap=cda25f51ce994443a592011ecec15e03&amp;gcsextent=-160.3411,18.6238,-154.6612,22.7594&amp;displayslider=true&amp;displaylegend=true&amp;displaydetails=true&amp;displaysearch=true"></iframe><br /><small><a href="http://histategis.maps.arcgis.com/apps/OnePane/basicviewer/index.html?appid=8d6af87ca1f249878b2e6beb9a38ebecstyle="color:#0000FF;text-align:left" target="_blank">View Larger Map</a></small>

Copy and paste the above code into your web page and you'll have an embedded web map just like the one above.

Use the comments if you have any questions on this.

A hui ho!
