Is This Land Any Good? Land Capability Maps on arcgis.com

Let’s say you’re a farmer or farm real estate broker, and you are evaluating whether or not to buy a piece of land.  Your business and your livelihood depends completely on the land and its capability to produce income.

How do you tell the difference between a bad piece of land and a piece of land that has good potential but hasn’t been managed well or has otherwise been neglected?  What can the piece of land do, and what is it really worth?

In a time of great uncertainty and volatility in financial markets and real estate valuation, the inherent capability of a piece of land’s soil asset has just become a lot easier to estimate.  Image credit: USDA

To help answer these questions, esri has produced two new maps and map layers on arcgis.com.  Both are planning-level maps of the economic capability of the United States’ soils.  One map shows the economic capability when the soil is irrigated and the other when the soil is not irrigated.  These maps are entitled Irrigated Land Capability Class and Non-Irrigated Land Capability Class, respectively.

Both maps are made directly from the SSURGO planning level soil dataset from NRCS. For the more technical among us, we used the MUAGGATT table fields ICCDCD and NICCDCD from SSURGO.  Both maps cover the entire USA including Hawaii, Alaska, and Puerto Rico.

At 1:24,000 scale, each part of the United States falls into one of eight broad land capability classes.

The first four classes (1-4) are useful for growing crops, where each class from one to four needs more management or treatment, and has more limitations than the previous class. For example, classes 3 and 4 require more management or treatment than classes 1 and 2.

The last four land capability classes (5-8) are not useful for crops.  NRCS recommends these lands be used for things other than crops, like rangeland, forestland, or wildlife habitat. Class eight isn’t even good for forestry, pasture or rangeland, and so instead NRCS recommends those lands be used for recreation, wildlife habitat, watershed, or aesthetic purposes.

Non-Irrigated Capability Class

These maps feature a color scheme (shown here in 50% transparency) that matches an image of a sample landscape that you see when you click on each soil map unit.  This graphic may then be used like a second legend, displaying the eight classes for you on a replica landscape.

Land Capability Class is one of the most important concepts in the US soil dataset SSURGO.  Land Capability Class is even used in some states for property tax assessment. In the State of Ohio, for example, the tax code prescribes specifically how to use this map to determine property tax.

Esri plans to release more land capability maps, specifically Land Capability Subclass. We will let you know as soon as these maps are complete and online, and rest assured that the subclasses will be in a format that is easily mashed up with either the Irrigated or Non-Irrigated Capability Class maps.

New Parcel Value for iPhone Template provides authoritative land records data on iOS platform

Parcel Value for iPhone is an ArcGIS API for iOS application that provides public access to tax parcel and related assessment information. It includes a simple application for the iPhone that allow users to interact with your authoritative parcel maps, property characteristics, and related operational layers (property sales and foreclosures).

The Parcel Value for iPhone application offers a standard overview of property data in a community for real estate and other consumers so they can view this information on all homes as they walk or drive through neighborhoods. Users are able to search for a specific address or parcel number, view authoritative property characteristics, sales and foreclosure information, and email this information to a friend or co-worker.

The Parcel Value for iPhone application comes with two base maps.  The first is a representation of tax parcel information for the consumer, and contains content that has been optimized for the general public and other casual users of parcel information. The second base map is a representation of tax parcel information for tax map users; and contains content that has been optimized for individuals experienced with hardcopy tax maps and related land tenure elements. These basemaps will appeal to general consumers of land records information and professionals in the real estate community that are looking for map elements that correspond to the legal description of property.

The application also provides a unique way for users to interact with condominiums maintained in your Parcel geodatabase.  When a user selects a condominium, they are presented with a list of units within that condominium development.  They can then navigate through the list to find the appropriate unit and when they do, review the property characteristics and share it with others if they’d like.

When you configure the Parcel Value for iPhone template in your environment, you’ll learn how to publish and serve your own maps using ArcGIS API for iOS, ArcGIS Server, and your organization’s data. Then you can deploy a Parcel Value for iPhone application with your authoritative parcel data on the Apple App Store for users within your community.

If you’d like to see the Parcel Value for iPhone application in action, check out the video posted on the Local Government Resource Center.

We look forward to your feedback and seeing your Parcel Value for iPhone application hitting the Apple App Store soon.

Announcing the Land Records Templates

One of the highlights of the Land Records Resource Center is a set of templates built with core ESRI technology. We’ve posted three templates for the launch of the Land Records Resource Center. These templates are for maintaining tax parcel information, sharing information with the public, and analyzing the impact of property value and revenue changes in your community. We will be working on other templates relevant to assessors and the land records community, which we will post in the future. The goal of our templates is to give you real-world examples of how to deploy the ArcGIS product suite in your industry. In each template you’ll find a sample geodatabase, map documents, an application and the documentation to help you configure the template. Also, check out the videos that we’ve posted to give you an introduction to each component. We would like to thank Bloomfield Township, Michigan for allowing us to include a sample of their data in our template downloads. By using real data these examples become more compelling. We’re grateful for Bloomfield Township’s help in promoting the use of GIS for Land Records. We decided to create these templates because we wanted to pass on to our customers best practices, successful deployment patterns and share industry specific knowledge. Remember, the Land Records Resource Center is for ESRI users – so we encourage your feedback on the templates we’ve provided and ask that you post comments for each template. We’ll be using your comments as a guide for changes to our templates and for new templates we’ll develop in the future. We welcome your feedback, comments and suggestions. You can either post comments to this blog or e-mail us at ArcGISTeamLandRecords@esri.com Thanks! The ArcGIS Land Records Team
