Cave Densities in WV - Applied Geography Presentation

Here are the slides from the talk I co-presented with my Mansfield University colleague Lee Stocks at the 2014 Applied Geography Conference in Atlanta this past Thursday. The presentation resulted in our paper being published in Papers in Applied Geography, volume 37. Read more

Resolution and Coverage Testing for Phantom 2 Vision+ UAV Imagery for Mapping

A few days back, I sent up our new DJI Phantom 2 Vision+ above the Mansfield football stadium for some imagery testing, and published a blog on doing lens corrections for mapping. Now, I'm going to take those corrected images to the next step and test their resolution and coverage to see how effective this equipment is for providing high-quality, high-resolution and low-cost remote sensing imagery for mapping applications.

Lens Correction on DJI Phantom 2 Vision+ for Mapping

The new prevalence and inexpensive nature of UAVs has given cartographers and spatial scientists a great new tool for creating extremely high-resolution (both spatial and temporal) maps of places. At Mansfield, we've got several platforms that we're using. Read more

Fun with Maps: Resolution Test GIF

I took the Phantom 2 Vision+ out to do some resolution and lens correction testing this morning. Part of this required using the football field on campus, since it provides some nice measured straight-line geometry that can be used to gauge the resolution and correction to ensure accuracy. But, while I was doing this, I messed around a little bit with the resulting imagery and made a little animated GIF Read more

Mapping Biomes for the Plaid Avenger: Adventures in Georectifying and Symbology

This summer, I've been enjoying doing some work for the Plaid Avenger, especially creating new maps for his next edition of The Plaid Avenger's World, an excellent alternative textbook for world geography courses. Some of that work, particularly mapping biomes, has been a bit of an adventure. Read more

Cave Density of the Greenbrier Limestone Group, West Virginia

Note: This is a paper I co-authored with my MU colleague Lee Stocks, forthcoming in Papers in Applied Geography. The Greenbrier Limestone Group, known in West Virginia as the “Big Lime”, is an extensive, calcium-pure limestone unit of Mississippian Age (350-340 million years). Deposited in a shallow ocean basin during the Carboniferous, the Big Lime is over 1000 feet thick in the Greenbrier Valley of West Virginia. The wet climate of central Appalachia provides the hydraulics and corrosive carbonic acid action necessary to form frequent and sizeable karst dissolution features, such as caves, sinkholes, and springs.

My AAG 2014 Talk: Quantum Geographies: Applying Einsteinian Space-Time, Metaphysics and Multiverse Theory to Four-Dimensional Interpretation of Places Memorializing Tragedy

This is my AAG talk, given this past Thursday afternoon. I'm only posting the slides because I did not write a full narrative for this talk. I think readers can generally follow from the slides below, though. It was probably too ambitious for 15 minutes, and I don't know if I'll ever revisit this idea again, but it was still a fun talk to give. Read more

My alt.conf talk: The Age of Cartographic Impressionism

I actually did finish this around six hours ago, but... I can't sleep. So, I'm going to go ahead and post my first AAG talk here, a lightning session for the GeoWeb and Big Data alt.conf I helped to organize. Read more

Re-Constructing the Map, Revisited: NBC's Geographic Imagination in the 2014 Winter Olympics Opening Ceremony

A couple of years ago, during the Opening Ceremony of the 2012 Summer Olympics in London, I got the crazy idea to map seconds of coverage of each delegation when I saw NBC constantly cut away from lesser known countries after just a few seconds as compression editing for the tape-delayed broadcast.

My friend and colleague, Emily Fekete at the University of Kansas, prodded me to explore it further in a published collaboration.

Resolution Tests for MU UAV Imagery

I performed some tests with our primary imaging camera today to determine the potential resolution of the sensor, spatial coverage, and its viability for various imaging applications. In estimating the potential power of our sensors, it appears we might be capable of mapping on a scale that is largely unseen ("micro-mapping"), with the drone potentially capable of providing very high resolution remotely sensed imagery. However, testing was needed to confirm such possibility before application of the technology in the field. Read more
