Notes from the Esri Federal GIS Conference 2012

Thursday, March 1st, 2012

This past week, 3500 people attended the Esri Federal GIS Conference held in Washington, D.C.  Attendees came from virtually every federal agency, nongovernmental organizations (NGOs), GIS companies and other agencies that support federal and state agencies.

Esri president Jack Dangermond kicked off the plenary with a reminder that the world is rapidly changing and we are confronted with new issues such as loss of biodiversity. GIS helps to build intelligence about these issues.

“If we take raw data we can turn it into information by mapping it, that’s why it’s so exciting to look at maps,” said Dangermond. “And now with the dawning of the cloud web world pattern for GIS we’re seeing how we can share this knowledge and create better understanding. GIS drives understanding.”

Some user work was showcased such as the first global dataset of biomass – in Woods Hole, and the relationship between hydrology and biofuels.

Presenters focused on topics such as integration, collaboration and breaking down government silos.

Ethnic diversity maps on Esri’s storymaps

Wednesday, February 22nd, 2012

U.S. ethnic and racial diversity maps are available from Esri between 2000 and 2010 and show that between those years, diversity increased most dramatically.

According to Esri, a Census Bureau index measures diversity from zero to 100. The diversity score for the U.S. in was 49 in 2000, which means there was a roughly 50 percent probability that two people randomly chosen from the population belonged to different race or ethnic groups. Hispanics, which totaled 35.3 million in 2000, accounted for a significant proportion of this overall diversity.

There’s an app for that – from CitySourced

Friday, February 17th, 2012

Residents of Longview, TX (reported on earlier this week – “There’s an app for that – citizen pothole reporting”) with smartphones can get a new mobile app called “CitySend“ created by CitySourced (didn’t credit that company in the first blog) to inform public works officials of their public issues. The mobile app, unveiled by Longview GIS Manager Justin Cure, allows users to take photos, record video and audio of a problem, and automatically provide GPS coordinates. After the report is submitted, users can track all reported problems on a map as well.

Drought mapping using measurements obtained from weather and research satellites

Monday, February 13th, 2012

The National Oceanic and Atmospheric Administration’s (NOAA) Center for Climate Prediction holds a monthly drought briefing by teleconference to identify the latest drought areas in North America, according to  Don Comis of the USDA Agricultural Research Service (ARS). ARS scientists, Martha Anderson and Bill Kustas, are hoping that in a year or so, data from their computer model/satellite package will give evapotranspiration (ET) maps a seat at that briefing.

John Snow’s 1854 Cholera Map comes to life with the CartoDB platform

Thursday, February 9th, 2012

John Snow created a map of a cholera outbreak in the district of Soho, London in 1854, which helped to convince authorities that the disease was caused by water ( in particular, it originated from one pump in Broad Street). The CartoDB platform allows you to map data and develop location aware applications very easily. This example of John Snow’s Cholera Map of London presented with CartoDB demonstrates how CartoDB can quickly combine different data types, then display them on a map.

How to measure the world’s largest cities

Friday, February 3rd, 2012

Scholars are having trouble measuring the world’s largest cities – largely because the terms the cities are measured by differ from place to place. They have come up with a total of 30 largest cities in the world.

Richard Greene, associate professor of geography at Northern Illinois University in the United States, says even the most authoritative list, from the UN, “compares apples with pears”.
