San Diego Geographer Looking for Influential Tweeters to get Emergency News Out
Official emergency messages from the county of San Diego in the future might be spread by the region’s most influential “tweeters,” San Diego State University announced Monday.
Ming-Hsiang Tsou, an SDSU geography professor, is compiling a list of 1,000 influential Twitter accounts based in San Diego, so emergency messages about evacuations, road closures and the like can be spread faster or targeted more closely to certain locations.
Top tweeters will be those who retweet the most news from the official city account and local news outlets.
“If we have 1,000 highly influential volunteers retweeting these messages, almost everybody in San Diego will get the message,” Tsou said.
I'm not sure I buy it. Who says the followers of these people are necessarily in San Diego? Perhaps Tsou is also looking at that with her NSF funding.
DigitalGlobe Helps Map Mongolia, Along with Mapbox
DigitalGlobe, a leading provider of global commercial Earth imagery and geospatial information, recently granted The Asia Foundation high-resolution satellite imagery for tracing in OSM. The new imagery is more recent and of higher quality than anything previously available to OSM editors, who will use it as a guide: adding roads, buildings, rivers, railways, and other features to OSM’s map of Ulaanbaatar. Mapbox, which provides a powerful and diverse platform for the creation of custom online maps, has processed the raw satellite imagery to prepare it for use in OSM and is hosting the resulting map tiles.

When Water Districts Collide
So, best I can tell, there was deal between a water district and a public utilities district that allowed them to share an Esri enterprise license. But then the deal was terminated, so each would have to pay it's own $27K. But, maybe a new deal will be made and the merger will again share a single license. The whole thing is going on in California...during a drought.

It's with deep sadness that I learned of the passing (obituary) of Dr. David Huff, formerly a professor of business administration at the University of Texas, Austin. Huff passed away on August 30th.
David Huff, for those that have studied retail geography and market analysis, knew him best as the individual who developed the model for forecasting market share and retail attractiveness in 1964. The Huff Model has been widely applied since to locate convenience stores, shopping malls, and other types retail establishments. It is used today still by those doing sales forecasting and has been incorporated into GIS systems.
The photo above was taken with me in 2007 at the Esri User Conference in San Diego. David had consulted with Esri and supported the development of modeling for Business Analyst.
As many who knew him will recall, David would remind us that his model was NOT a gravity model. In fact, distance decay was only one factor of many that could be used in his model of attractiveness as were other non-spatial factors.
I can't say that I new David well, and surely his students would have many memories of his incredible intellect, but I can say that he was one of the greater influences in my career as I looked to study and write about retail geography and GIS. I first met him in 1989 at the Applied Geography Conference and would speak with him at conferences or by phone to discuss how to convey the integration of his theory with today's GIS. David was always willing to offer great counsel and I always felt honored to speak with him on matters both technical and personal.
During my career, I've had the pleasure of interviewing notable individuals, from politicians to writers to technologists. David Huff is at the top of this list. He will be greatly missed.

Deadly Disease Interactive
The Daily Mail's interactive piece looks at the world’s deadlist outbreaks, as well as history’s most dangerous diseases.
Ebola Tracking Via Cell Phone
The Centers for Disease Control and Prevention is tracking the approximate locations of cell phone users in West Africa who dial emergency call centers in an effort to predict the onset and spread of Ebola outbreaks.
"The data is just the number of calls by cell tower but from that you can get a rough idea of the area that the calls are coming in from, and then derive census, neighborhood data from that," CDC spokeswoman Kristen Nordlund told Nextgov on Thursday.
There's also discussion of Esri's participation in the ebola response effort in the Mashable piece.
Is Geomedicine Reaching a Tipping Point?
That's the word from participants at Duke's Geomedicine Summit held Oct 13-14. Participants argue the technology has reached a tipping point of interest, but major barriers remain. So, clearly there is room for expansion (Esri and Cerner were sponsors). Most interestingly, one challenge is simply capturing and geocoding current and past addresses of patients in their medical records. Said another way, there are still challenges put dots on a map!

State of the Art Campus Map
Claremont McKenna College (CMC) has launched a new interactive campus map. It's got 3D and is based on Google Maps. There's a story map-like tour, too. Suggestion: It might valuable to ask Claremont Graduate University GIS folks for some input on the next iteration.
Esri MOOC Certificate
Since students love certificates, one posted hers to Twitter. The Udemy/Esri certificate page text notes:
This certificate above verifies that xxx successfully completed the course Going Places with Spatial Analysis on October 9, 2014 as taught by Linda Beale, David DiBiase and Ephraim Ross on Udemy. The certificate indicates the entire course was completed as validated by the student.
You might notice it does not say Esri anywhere. @esrimooc responds:
University of Denver FOSS4G Lab
The global ICA-OSGeo-ISPRS labs
are pleased to announce the launch of the University of Colorado Denver's FOSS4G Lab
. Thanks to Dr. Rafael Moreno-Sanchez who has been leading this at University of Colorado, Denver, USA. It is also great to see the establishment of an international advisory board for the lab to review plans and activities and provide advice for the growth and future direction of the lab.

Waze Partners with State/Local Govs for Traffic Data
Waze announced its “Connected Citizens,” a new government partnership program that will see both parties exchange data in order to improve traffic conditions earlier this month. No money is changing hands, just data.
Leesburg Uses Existing License for Planning App
The Leesburg Interactive Application Map, located at leesburgva.gov/LIAM, allows residents to see the locations of all active and recently approved land use applications within the town at a quick glance.
Since the West Virginia town already had an Esri enterprise license, staff tweaked a story map template to build the app.
