Flagstaff – Then and Now

I’ve been working on a repeat aerial photography project with NAU’s Cline Library (this is the second part, the first part was (here) and below is an additional proof of concept element for a proposed Hanks Internship that I’m hoping to find a student to work on this fall. The images on the left are based off 0.5m resampled orthoimages for Flagstaff taken in 1959 by Andre M. Faure. The images on the right are corresponding (same resolution, same location) but from 2014. The viewer is based off of Jan Pieter Waagmeester’s Leaflet.Sync plugin and the images (1959 & 2014) are served up by Mapbox.

Flagstaff in 3D – circa 1959 via A.M. Faure and Cline Library

The following is something I produced as a proof of concept for a proposed Hanks Internship with Cline Library this fall (if you know of any students, please send them my way!). The scene was produced from 122 aerial photographs take by Andre M. Faure in 1959 and covers the majority of Flagstaff, AZ. Faure was a city planner for Tucson from 1941 to 1968. Prior to his arrival in Tucson, Faure served as a planning consultant in Connecticut and a town planner in New Jersey. He worked with the City of Flagstaff and Coconino County on various projects in the 1940s and 1950s. Some of which are aerial photographs of Flagstaff, Williams and Sedona used by Faure for city planning in 1959, and they are available for online viewing in the Colorado Plateau Digital Archives.

Flagstaff – 1959

The Dorothy T. and James J. Hanks Cline Library Endowment supports Northern Arizona University students for research in repeat photography. A primary goal is to locate and document camera stations of photographs held by Special Collections and Archives, with emphasis on images from the Colorado Plateau. Cline Library Hanks Scholars enhance the library’s photographic collections by increasing knowledge and discovery in the natural or social sciences. Hanks Scholars are given a unique opportunity to develop an appreciation of the value of historic photographs and repeat photography. NAU’s Special Collections and Archives is the official repository for the James J. Hanks Collection.

More Fun with LiDAR

LiDARPlotView Just a little animated GIF showing LiDAR from the North Kaibab. Notice the penetration achieved and the resolution it provides for picking out large trees, small bushes, and topography.

Advancing Forestry Education by Biting Off More than I Can Chew

DSC_0133It should come as no surprise that there is an ever-increasing demand for competent forestry graduates; especially those who able to address complex economic, ecological, and social issues involving forest resources. However, Forestry is a traditional discipline and often finds itself challenged to educate students using 21st century technology and sciences to solve these new problems.

Last semester, a senior faculty and I proposed providing forestry undergraduate students with a redesigned, senior-level course in Ecosystem Assessment that would maximize the use of mobile technology with the following course objectives: 1) students will have enhanced, forestry-centered learning opportunities in both the field and classroom, 2)these experiences will improve the way students visualize spatial and temporal aspects of a forest resources and landscapes; and 3)ensure NAU’s School of Forestry remains in the forefront of forestry education.

This Fall, in FOR 413 & 414C (Forest Ecosystem Assessment I & II) at NAU, 39 undergraduate students will be let loose carrying 20 Dell Latitude 10 tablets running Windows 8 to collect and analyze forest resource data from a 4-sq. mile area on NAU’s Centennial Forest.  These data will be collected over a five-week period using a FVS-ready Access database for tabular data and ArcPad 10.2 with the tablet’s built-in Global Navigation Satellite System (GNSS) for spatial data.

The students will use this technology to integrate material learned in prior forestry courses while learning and applying new concepts and skills focused on the interpretation of remotely sensed imagery, land records, and ownership limitations; use of geographic information systems (GIS) and field protocols for inventory of biophysical features; and simulation of potential stand development pathways.

Fun with LiDAR

LiDAR
So I finally got my hands on the North Kaibab LiDAR acquisition and it’s huge (~2TB). I was able to find a few minutes to play with it (in ENVI) to produce this simple figure of the landscape surrounding Matt Tuten’s research sites. Cool beans…
