Mapping the Health Care Debate

The recent Supreme Court decision to uphold President Obama's health care plan has been received with mixed feelings across U.S. states. The goal of the health care plan is to ensure that all American's have an equal opportunity for health care insurance. A key aspect of the Obama health care plan was to expand Medicaid to cover those who were not covered by Medicare. This expansion was meant to fill the gap for people who couldn't afford insurance, but were determined to be poor enough to be exempt from the penalty for not holding insurance. The penalty for not …

Mapping Idea Tolerance in U.S. Cities

Richard Florida is the well-known author of the book "The Creative Class" which describes the rise and the importance of a socio-economic class of individuals that Florida believes drives economic and social development. According to a Wikipedia, the creative class is made up of two separate groups of workers that make up about 30 percent of the U.S. workforce.

Streamlining Workflow when Adding Features

When creating maps that involve drawing new features such as points, lines, and polygons it is often the case that you may want to create several new features that are exactly the same. Essentially, you may want to create identical features without having to re-draw each one. Cartographica has multiple functions that allow you to perform this task. I will illustrate with an example using polygons. There is a pavilion structure in downtown Lexington, Ky that is used for various events, one being its hosting of the local Farmer's Market on specific days throughout the week. In Lexington, one of …

Georeferencing Detailed Cold War Era Maps using Cartographica

According to a recent article on Burrito Justice, during the Cold War the Russian government spent a lot of time and effort to create detailed maps of the many places in the world as potential targets for their military. The maps detail many different aspects such as elevation, water ways, and even streets that would be passable by tanks and other military vehicles. Now that the Cold War is over we can talk about the absurdity of it all and enjoy the hard work that the Russians put forth to make a series of really nice maps. The best location …

Mountain Lion support and the Future of Cartographica

It's been about two years since I made this post about Snow Leopard and ClueTrust's plans to drop support for Leopard (10.5) in versions 1.2 of Cartographica and beyond. Since that time, we've had rapid adoption of Snow Leopard (10.6) and, in the past year, Lion (10.7) by our users (according to those statistics that you hopefully have been allowing us to capture). Earlier this month, we once again attended Apple's WWDC and we learned a lot about how we can take advantage of the new features in Mountain Lion and that Apple has now lowered …

Investigating International Incidents with Cartographica

The recent troubles in Syria have escalated a little farther when Syrian Forces shot down an American made F-4 Phantom Jet flown by Turkey. Multiple news sources are reporting on this issue and there have been some inconsistencies about what actually happened. According to an article written in the Telegraph, the Turkish Foreign Minister has stated that the F-4 was shot down in international airspace after briefly entering Syrian airspace. The attack came without warning to the pilots of the jet. Secretary of State Hillary Clinton has condemned the attack and has been quoted as saying that the attack was …

Map Diabetes in the United States with CDC data

The Center for Disease Control monitors various diseases within the United States. Often the CDC produces data for public use that can be used for scholarly and educational purposes. For this post I downloaded diabetes data from 2009 from this CDC website. The CDC are available for download in .xls format, so they need to be converted for use in Cartographica. After the data are downloaded, load the files into a spreadsheet program and save the file as a .csv. According to CDC data more than 25 million Americans have been diagnosed with diabetes and the rates of diabetes have …

CartoMobile: Your data in your hands

There are a lot of mobile mapping applications for iOS, and even with that as a backdrop, we decided to develop and release CartoMobile because we saw a place for a sophisticated and easy-to-use App for creating and accessing your geospatial data from anywhere. We're often asked what sets CartoMobile apart from other mapping Apps for iOS. Basically, we believe that you should be able to have easy access to your data on the go. Here's how we have done this: No Need to Import/Export — CartoMobile handles shapefiles and raster files directly. There's no need to do any coordinate …

Where are those FAA-approved Unmanned Drones?

In an article released last week it was reported that the Federal Aviation Administration has released the names and locations of Organizations approved for flying drones within the U.S. Drones have become infamous over the past several years due to their use for military purposes in Afghanistan, Pakistan, Iraq, and many other places. The use of the military technology for domestic purposes should not be unexpected as we have seen many military technologies cross-over for domestic purposes. Many argue that the use of such Military technology in local police agencies may be problematic and seen as an increase in …

Core Logic Report on Wind, Hail, and Tornado Risk

We have done a lot of posts about tornado activity in the past on this blog. This is largely due to the interesting data that are openly available as well as the awesome power that tornadoes contain, which naturally makes them interesting. The recent tornado activity in Indiana and Kentucky and then Monday's dramatic daytime tornado that ripped through through the Dallas area has again brought my attention back to tornadoes. Recently Core Logic produced an interesting study on tornado and hail damage throughout the United States. Get the article here The report looks at similar data that we have …
