The US Census Bureau just released the first public publication of the 2020 Census Geography through TIGERweb. This includes the 2020 Census Blocks, Census Block Groups, and Census Tracts. Download the new Census Geography Files today!
For those of you that participated in the Boundary and Annexation Survey (BAS), the new files can be found here.
Before I take off for the rest of the year, I would like to wish everyone a very Merry Christmas and a Happy New Year. Enjoy this year’s Christmas Map! -mike
Depending on where you live, here is the historic probability of at least 1 inch of snow on Christmas. Spoiler alert, Los Angeles is 0%.

Received an email from ESRI a few days ago about them updating ArcGIS Online on December 8, from 5 pm-midnight PST. This update will include new features and enhancements that improve security policies and administrative capabilities, including HTTPS enforcement, end of support for Internet Explorer 11 and Microsoft Edge Legacy, managing the organization’s access to apps, adding a new Asia-Pacific region for new organization subscriptions, and new charts for monitoring Data Store usage.
More details below:
| HTTPS Enforcement ArcGIS Online will enforce the use of HTTPS on the night of the update. This change has been communicated over the past year, and the December update will enforce the policy across all of ArcGIS Online. The enforcement of HTTPS ensures that all data is encrypted, confidentiality is improved, and sensitive data is secure. For more information about how to prepare for this change and potential impacts, please read the following article. |
| End of ESRI Support for Internet Explorer 11 In accordance with Microsoft’s official retirement of Internet Explorer 11 and Edge Legacy, both Internet Explorer 11 and Edge Legacy have been deprecated with ArcGIS Online. With the December update of ArcGIS Online, customers will no longer be able to receive support with issues related to Internet Explorer 11 or Microsoft Edge Legacy. We recommend using the latest version of Google Chrome, Mozilla Firefox, Apple Safari, or Microsoft Edge in order to avoid any performance issues. Starting with the December 2020 update, any users that use IE11 or Edge Legacy to view ArcGIS Online applications or the website will receive an information message indicating the usage of an unsupported browser. |
| Manage Organization Access to Included Apps To enable organizations to comply with policies such as FedRAMP, and to have more control over which apps their organization members can use, administrators will have the ability to block access to included ESRI applications. Administrators can choose to block apps that are included with all user types and cannot be controlled through licenses, settings, or privileges. |
| New Asia-Pacific Region for Hosted Data An Asia-Pacific region will be introduced as an option for any new ArcGIS Online subscriptions. This region will provide a new location for hosting data in addition to the existing US and European regions. Please read this article for the details of how data hosting works with our regions. |
| New Usage Chart for Feature Data Store A new chart, available to administrators through the Organization tab, will provide more insight into the feature data store that powers hosted feature layers. All administrators will be able to quickly view the current usage of the organization’s allotted storage. For organizations that have purchased a Premium Feature Data Store subscription, a new chart will be available that displays the utilization of the resources over-time. |
This FREE crash course (tutorial) will teach you a basic understanding of how to use and interpret historical aerial photographs (air photos).
This tutorial is designed to be used by adults including undergraduate students. The tutorial is a serious endeavor created to teach you something; it is not a site for pretty pictures.
The tutorial is broken into 2 parts — introductory text and quizzes. The introductory text can be completed in approximately 30 minutes. The quizzes are skill-building exercises and can be completed in 30 to 45 minutes.
In this tutorial you will learn:

This year’s Thanksgiving map is from Google looking at uniquely searched side dishes in each state this year. Gravy seems to be the thing in California. Mac and Cheese in West Virginia! Cornbread dressing in the South … what is that? Happy Thanksgiving!
According to NOAA, flooding is the major threat for inland populations. Flash flooding can occur quickly due to intense rainfall, often accumulating from some distance away from where the flooding occurs. Flooding along rivers and streams can last for many days after a storm has passed. See how you can use ArcGIS Online and ArcGIS Living Atlas to make a flood map in no time at all.

GIS Day 2020 is here. Most of us are probably celebrating virtually this year. Check out what is going on at LA County, they have a great lineup.
And if you have something going on, just post a comment below and links to your event.
Also ESRI has a nice map showing where GIS Day events are going on.
Happy GIS Day!
The Library of Congress is having a conference tomorrow, and since it will be virtual for GIS Day, anyone can attend! The Geography and Map Division is bringing together a panel of experts, on Wednesday Nov 18th, who are at the forefront of using GIS to track and fight the spread of SARS-CoV-2, the virus that causes COVID-19.
Mapping a Pandemic: Cases, Traces and Mutations, will take place tomorrow in honor of GIS Day 2020 and National Geography Week.
Experts from Johns Hopkins University and ESRI will be joining to discuss the geospatial and genomic data being used to understand the pandemic and examine how mapping and GIS technologies are helping public health officials, emergency rooms, epidemiologists and the public grasp the spread of the disease and decide on allocation and distribution of precious resources, like vaccines.
For epidemiologists, studying the virus and its evolution and mutations, not to mention thinking about the distribution of potential vaccines, the pandemic has inspired widespread use of GIS, and new geospatial machine and deep learning technologies. Scientists and public health officials are relying on these new mapping and computational methods to understand the viruses spread and on new visualization techniques developed by cartographers to track the geospatial dynamics of its mutations.
Speakers are:
Keynote:
Dr. Este Geraghty, Chief Medical Officer at ESRI
The Role of GIS in Fighting the SARS-CoV-2 Pandemic
Technical Papers:
Ensheng Dong, Center for System Science & Engineering, Johns Hopkins University
Historic First: Mapping the Pandemic in Real Time
Mike Schoelen, ESRI Health and Human Services
Driven by GIS: A Resilient Supply Chain for COVID-19
John Hessler, Library of Congress & Johns Hopkins University
More Than Just Cases: Mapping the Mutations of SARS-CoV-2
These presentations will premiere on Nov 18, at 1 PM EST (10 AM PST), with closed captions on both the Library’s YouTube site at https://www.youtube.com/loc/ and on the Library of Congress website at https://www.loc.gov/collections/event-videos/. The presentation will be available for viewing afterwards at those sites.
