Juvenile Crime in Ohio

An interactive map created by the tech team at the Cuyahoga County [OH] Prosecutor's office offers a glance at juvenile crime countywide last year.

The map is based on Tableau and has prompted some discussion of how to focus resources on the issue, though numbers have dropped over the years.

Where to Put Industrial Ag in SD

The rural, outlying areas of Davison County, S.D., would be some of the best choices for an animal feeding operation or an industrial ag business, according to a recent state-funded study.

The study, done by Planning and Development District III in Yankton and the South Dakota Department of Agriculture, used GIS mapping software and identified which properties in the county would be suited for projects such as a large-scale hog operation or a grain shuttle loading facility.

The study was state funded and the big issue in locating such services is a shallow water table.

Connected Warrants and Child Safety

Albuquerque police want to ensure child abuse cases don’t fall through the cracks by providing officers with crucial information when responding to calls.

“We’re looking at what we call GIS or GPS technology that would alert an officer’s cell phone if they step foot on a property thats connected to a warrant,” Wilham said.

From the Coursera course registration page:

What happens when creativity and science come together? The power to design our world is unleashed, providing tools to inform choices about how we live! Geodesign is the glue—it’s a process that deploys creativity to connect information to people, using collaboration to better inform how we design our world.

The course runs for five weeks and starts in August. No software is noted. Penn State offers a certificate in geodesign, so my sense is this course is aimed at both introducing geodesign and finding new certificate students.

Engineers at Tokyo-based Mitsubishi Electric Corp. report that they’re on track to start up the first commercial, nationwide, centimeter-scale satellite positioning technology. 

 Quazi-Zenith Satellite System (QZSS), will work alongside the U.S. GPS system, meaning data in Japan will be at the centimenter level, not the metres or so gpS provides without correction.

The Japanese goverment has set aside US $B1.7 for the seven satellites and 1200 ground stations. One satellite is in orbit, with two more expected by 2017. The final three will follow in later years. A company,  Quazi-Zenith Satellite System Services, has been set up just to develop and run the ground system.

All of the correction will be done in real time and receivers will need a good sized antenna to receive the data. Test now confirm average accuracy of 1.3 centimeters horizontally and 2.9 cm vertically.

What will the Japanese use the extra accruacy for?

Besides pointing out obvious uses like mapping and land surveying, Sam Pullen, a senior research engineer in the department of aeronautics and astronautics at Stanford, says precision farming and autonomous tractor operations will be big applications. “Unmanned aerial vehicles and autonomous vehicles in general,” he adds, “will also find centimeter-level positioning valuable in maintaining and assuring separation from other vehicles and fixed obstacles.”

The constellation will also be used to send emergency messages when terrestrial communications are knocked out. Remember too that Japan has a number of big cities with tall building and mountains, so it suffers from "urban caynon" issues as we do here in areas like New York City.

The second offering of Maps and the Geospatial Revolution begins on April 30th. PSU instructor Anthony Robinson notes: "I'm eager to teach as many people as possible about what's cool in Cartography."

World Map of Suicide

Business Insider collected WHO and other data to create a world map of suicide rates. Data from developed countries is probably more accurate, while that from developing countries is more likely to be estimated. The data come from 2004 up to 2011. I'm not sure of the value of such a map, but perhaps it's the best we have.

Firefighter Fatalities

The National Institute for Occupational Safety and Health (NIOSH) has released an online map tracking firefighter fatalities in the United States. The map is built on HERE Maps and interestingly, while you can search on a number of criteria, geography is not one of them.

Map the Meal Gap 2014 is a detailed analysis of food insecurity done by Feeding America and the only study available that provides county–level estimates of food insecurity in the United States. The information is provided in an interactive map that allows viewers to find out how widespread hunger is in their community. But, don't be fooled the data comes from a 2012 collection, even though the PR is not clear on this fact. This from Feeding America:
The data was collected in 2012 and released by the USDA in September, 2013 as part of their report of Food Insecurity in the US – at the national and state level. We then work with the raw data and other inputs to determine estimates of food insecurity at the county and Congressional level.
Live High, Lose Weight?
 
Could it be that living at elevation and limited oxygen available helps keep those who are overweight from becoming obese? A study suggests that's possible.
US Air Force and Army service members stationed at high-altitude military facilities were less likely to transition from overweight status to obese status, according to findings published in PLoS One.
