The registration deadline for the Cities' COVID Mitigation and Mapping (C2M2) Virtual Symposium is days away. Don't delay: Register now for this free, public symposium that illuminates what spatial data and participatory mapping reveal about the global consequences of the COVID-19 pandemic for human lives and livelihoods.

​Hosted through Harvard University's Center for Geographic Analysis, in partnership with the American Association of Geographers, the symposium is led by the Cities' COVID Mitigation and Mapping (C2M2), a program of the Office of the Geographer and Global Issues at the U.S. Department of State, through its MapGive open mapping initiative.

International experts will share their insight from working at the forefront of monitoring the pandemic, sharing their data on local economies and social impacts of the conditions imposed by the pandemic. Through panel discussions, lightning talks, and keynote speeches by global experts, this free, virtual symposium will reveal what spatial data and mapping can tell us about the pandemic, seen through a variety of lenses, with a hands-on workshop on the last day.

From our friends at the National States Geographic Information Council (NSGIC).

NSGIC State Representatives and members of state GIS coordinating councils are invited to the May 4 Council of Councils Forum, to be held virtually from 1 to 4 pm ET. 

Register here or email Amy Holmes (amy.holmes@nsgic.org) for help with registration. Please note that members of state GIS coordinating councils - if not NSGIC members - may participate in this special virtual event at a rate of $20 per person. Email Amy with those guest names and she will assist with registration and invoicing.

Through several panels and interactive discussions, participants will hear the stories of several state councils as we explore various council models, purposes, and impacts. Next week’s discussion will continue on as we work to document the ‘anatomy of a council’ to articulate the essential components of a flourishing state GIS coordinating council. 

Please note you must be a current NSGIC member as well as a state GIO, NSGIC state representative, and/or state GIS council representative to register to attend or invite non-members of your State GIS Coordinating Council.

For those in local government working with Census data the following article may be of interest. It refers to the issue of Differential Privacy.  

From Wikipedia, the free encyclopedia:

“Differential privacy is a system for publicly sharing information about a dataset by describing the patterns of groups within the dataset while withholding information about individuals in the dataset. The idea behind differential privacy is that if the effect of making an arbitrary single substitution in the database is small enough, the query result cannot be used to infer much about any single individual, and therefore provides privacy.”

Census has been working on this issue for the past several years in advance of the release of the 2020 Census.  Not everyone is happy with or in agreement with the decisions surrounding this issue. 16 states, including Utah, back Alabama's challenge to Census privacy tool:

If you rely on Census data for demographic analysis we would recommend keeping up on this issue.

The U.S. Census Bureau recently announced the release of a new interactive apportionment map.  Here is an excerpt from their blog announcement: 

The U.S. Census Bureau launched a new online map ahead of the 2020 Census apportionment results release. The "Historical Apportionment Data Map" currently displays apportionment results for each census from 1910 to 2010. 2020 Census apportionment results will be added to the map as they become available.

The interactive map includes the following types of data for each census from 1910 to 2010:

• Number of seats in the U.S. House of Representatives.
• Changes to each state's number of seats in the U.S. House of Representatives.
• Population per representative for each state.
• Resident population of each state.
• Percentage change in resident population for each state.
• Population density of each state.

 
The interactive map also features:

• Downloadable tables showing the source data.
• Technical documentation.
• Optimization for mobile use

The ILGISA NG911 Committee was recently featured in an Esri Blog article! Thank you to all the volunteers who have spent countless hours on this project over the last few years!

​When someone in distress calls 911, the dispatcher and first responder must know where the caller is and how to reach them. The problem is, these questions can be far from clear. Cell phones don’t always convey an accurate location and street addresses don’t always match the map.

“A fire department deputy chief told me they regularly get calls from fire crews they send into a neighborhood where all the streets at one intersection have the same name,” said Peter Schoenfield, GIS analyst, Lake County, Illinois. “The dispatcher might say ‘Turn left on Lake Shore Drive,’ but they’re all Lake Shore Drive.”

That scenario is typical of how addresses can become barriers to accurate wayfinding. In the US, local authorities maintain addresses and update shared maps using a geographic information system (GIS). Data is then shared with 911 call centers, known as public-safety answering points (PSAPs).
