“Influenza poses a constant, heavy burden on society. Recent research has focused on ecological factors associated with influenza incidence and has also studied influenza with respect to its geographic spread at different scales. This research explores the temporal and spatial parameters of influenza and identifies factors influencing its transmission.

Spatial clusters of annual incidence of influenza (hotspots) in Jiangsu province, P.R. China, for the years 2004 (a), 2 006 (b), 2009 (c) and 2011 (d).

The company I currently work for is restructuring and as such, my current position has been eliminated and my employment will terminate on October 18th. If anyone knows or hears about an internship or job available in the Indianapolis, IN area, please let me know. I have set up my personal website with an résumé at http://www.jeffreyashby.com.

I have a strong work ethic and have excelled in my classes, as can be seen on my résumé. I am currently working on a couple of papers for publication and would really like to start getting some experience in the GIS field.
Thank you to everyone for any help you can provide.

Finally had a chance to make some changes to the site, so here is what’s new.

  • I have started a seperate page for the Putnam County @ Your Feet maps and moved the bedrock layer over to that page. I hope to have a surficial layer map up soon.
  • I am also creating a page for some heat maps and other items I am working on using the 911 call data from Putnam County, Indiana.
  • For my Advanced Remote Sensing class this semester, I am working on identifying Bobcat (Felis rufus) habitat in Southern Indiana. I will post the results of that here at the end of the semester and ask for feedback.

Besides maps, I am also taking a course on Applied Spatial Statistics (go Bayes’ Theorem!) and also data visualization class. Hopefully I can start adding some analysis to the maps and projects soon. As always you can follow my blog (I don’t post much so I won’t be cluttering up your life), also on Twitter (@JeffreyAshby) and on Facebook (jeffrey.ashby1).

The First Post

So to start of this blog dedicated to GIS and Geography, I thought I would toss out a few quotes I stumbled across while sauntering around the Internet.

“Everything has to do with geography.” – Judy Martz

“Geography is important, because it opens our eyes; a landscape is no longer a static feature, but a complex battleground of physical and human interactions. Local is no longer local, but a collision point for the interaction of many ‘locals’ drawn from a global stage. With technology increasingly drawing the world closer together, it is important that the role of Geography in helping the public in understanding this complex and unpredictable world is championed!” – Tony Cassidy

“Anybody who believes that the way to a man’s heart is through his stomach flunked geography.” – Robert Byrne

“If geography is prose, maps are iconography.” – Lennart Meri

Ok, that’s enough for now. I plan on posting about projects I work on, modified versions of assignments for classes, stuff I do for fun, and any other geographic and GIS items that come across my desktop. Some of it will be informational, so whimsical, and some tutorial. If you want to know more, check out the About Got GIS? And Jeffrey Ashby page for more.

I am currently looking for a job in the GIS field, so would appreciate your help in finding one. Preferably in the Indianapolis, Indiana area, or Central Indiana, or the United Kingdom, or Sweden, any of those areas are good.

I am a member of the Association of American Geographers and Golden Key International Honour Society. While most of what I do and show will be using programs like ArcGIS and ERDAS Imagine or Exelis ENVI, I may also delve into some of the open source programs like QGIS and Multispec.

Geography is fascinating to me, the where of it all, but with the tools available today we can use a combination of GIS and Remote Sensing to understand our world far better than at any other time. From knowing how well the crops are doing in the fields (and what is being grown there) with space based imaging systems, to knowing who will be affected if a dam should break. It is an exciting time and I can only see it getting better.

Did I say check out the About page? Get over there and look at some of the cool things I have done, then drop me a note at jlashby@iupui.edu.
