Map Hacks, Mashups and GIS


We should never loose sight of the power of maps - our end product. That power is exposed like never before through the momentum behind map mashups. And it has the potential to change the way we do business. The term "mashup" refers to websites that weave data from different sources into a new service. Popular new search engine maps (from companies like Google, Yahoo and Microsoft) have inspired people (referred to as map hacks) to put their own data on maps. This is enabled by simpler computer languages, open application programming interfaces (APIs) and web tools (GoogleMaps, for example, allows users to integrate data into it using just ten lines of code (www.google.com/apis/maps)). Mashups offer a creative way for ordinary people to share data - about a single person or by linking to publicly accessible/machine readable databases.


Web search engine maps live off of data created and used in traditional GIS. They feed off of the often tedious research, data collection, and analysis that create good data (good data in - good information out). They have already penetrated the global marketplace and are quickly unleashing the power to make geography ubiquitous. We may view this as a new opportunity to make critical information available to the public - information that was created by raw data and powerful GIS systems. This year, we should be on our toes examining the potential power of mashups. The web is no longer static - mashups are changing the way the web is used, turning the web into a global system. Should mashups be among the variety of tools in our own tool boxes?


Here are some of my favorite Google mashups (from serious to silly - enjoy!):

Where Do You Live?

Address Validation Software


Everyone cares about addresses, but not everyone cares equally. In Hamilton County, we have numerous databases that contain addresses and/or street names, including those from the Auditor's Office, the Sheriff, the Surveyor's Office, the Highway Department, and the Elections Office, to name just a few.


There is an old Chinese proverb: "A man with one watch always knows what time it is, but a man with two watches is never sure." In our case, it is sometimes difficult to know which database contains the "correct" address for a given parcel. We have also found there are different definitions of "correct."


As an example, in one subdivision, we have a discrepancy between the street name on the recorded plat and the commonly used street name (which is on the street sign). The Auditor's Office may consider the street name on the recorded plat to be "correct," but the mailman, the voter who lives on that street, the appliance delivery service, and the first responder will probably consider the name on the street sign to be "correct."


To further complicate the issue, addresses have zip codes associated with them, and in Hamilton County, we have a history of changing zip codes. In the past 20 years, we have added no less than five new zip codes and two new post offices. It is not an easy task to figure out which records in a database should be assigned a new zip code when one is created. Zip codes are not polygons!


I have recently learned of a class of products used primarily by companies who do mass mailings. The U.S. Postal Service has a process of evaluating address matching software known as Coding Accuracy Support System (CASS). Address validation software is actually a combination of software and the official U.S. Postal Service data files. This software is used to prepare mailings that are CASS-certified and therefore qualify for bulk mail postage discounts. The software can correct errors such as wrong street name spellings or incorrect zip codes. New U.S. Postal Service data files are released in February, April, June, August, October, and December, and CASS certification is valid only for data that is less than about four months old.


Although I am not exactly sure of the source or lineage of the data in the U.S. Postal Service data files, they are a credible and uniform source of data. If you are concerned with mailing addresses, address validation software may be exactly what you need. If you are concerned with physical addresses for some other sort of delivery or for emergency response, address validation software may still suit your purposes, as long as you are aware of its shortcomings for these purposes. There are some addresses that do not receive mail, such as businesses or residences that use post office boxes. These are still valid addresses for emergency response and real property taxes.

Using HAZUS-MH for Disaster Mitigation

Indiana State Emergency Operations Center: March 9-10, 8:30am - 4:30pm


The Indiana Department of Homeland Security is offering free Basic HAZUS-Multihazards training. This course will provide attendees with a working knowledge of the HAZUS-MH methodology and the GIS-based software. It will give a strong understanding of the multi-hazard applications of HAZUS toward mitigation, response, recovery and risk management. It will specifically discuss how HAZUS can be used to meet the ongoing requirements of the Disaster Mitigation Act of 2000. HAZUS-MH models earthquakes, floods, and hurricanes, but this offering will focus on the flood and earthquake modules of HAZUS since they are most relevant to Midwestern communities.


If you would like to register for this course, please send email with your name, organization, email, title(s) and date(s) of the course to hazusgis@yahoo.com. You may also call 317.232.3833 if you have any questions.

Evolving Economies


Chesterton, in northwest Indiana, is the third largest community in Porter County. Over the past 10 years, two major trends have effected the area: 1.) substantial increase in population and residential density, and 2.) instability in the steel industry. The town needed to coordinate growth management with an effective vision of economic development.


For years, the steel industry has been Chesterton's primary economic base. With the recent collapse and resurgence of the steel industry, however, the town was forced to take a closer look at the structure of the local economy. To diversify the economy, Chesterton needs to attract new development companies. So the town produces custom packages to reach commercial and industrial developers. GIS is used to create maps and data charts showing information vital to these companies: population growth, land use and transportation planning, economic conditions, natural areas, hazard mitigation, and infrastructure management. These maps and data charts highlight the benefits of locating in Chesterton, and identify development opportunities.


Using GIS as a marketing tool, Chesterton has been able to effectively sell the benefits of the community - and specific locations - to developers. The maps and data charts give corporations a way to see the transportation network, infrastructure, and other land factors, and how these things will impact them. Using GIS as a tool in the development packages helps Chesterton successfully compete for economic growth on a global level.

Where to Buy


To attract new business to the state, the Indiana Economic Development Corporation has implemented a web-based mapping application that can search through a database of available properties and buildings statewide. Users can search for buildings or land, and query whether a property is for lease or sale, specify dimensions and square footage, and whether the property has railroad access. Once a selection is made, the user will view a map with icons representing matches. The user can then click an icon and get general information about that property or building and possibly a photograph of the site. Visit the new site and building database at www.in.gov/iedc/site/indiana_properties.html.
