This week in the SAL, we continued working with Ryan Abrahamsen from Terrain360<\/a>.\u00a0 Last week we modified visual hierarchies on basemaps to make them more aesthetically pleasing.\u00a0 To do this, we used the open source program called Mapbox. Mapbox required us to code in CSS, something none of us had ever actually done.\u00a0 While most of us had coded in some regard in the past, it was either a new language to learn or a new experience altogether.\u00a0 The basemaps we created and visually modified are used to house the trails and panoramas mapping them.<\/p>\n

Example of what a trail looks like in Terrain360. This is the Mud Creek Trail near Ancarrow’s Landing. Found here: http:\/\/t360.it\/QN0010\/0\/0\/1<\/p><\/div>\n

This week, we were given the opportunity to actually go out and take the pictures that will go on basemaps like the ones we created.\u00a0 Using a Canon Rebel T3i with a wide-angle lens on a carbon fiber tripod with a 60 degree rotatable head provided by Terrain360, we were able to take wonderful and accurate panoramas.\u00a0 While in the field, a series of 6 portrait-aspect pictures were taken that overlapped for about a third of their girth due to the wide-angle lens.\u00a0 A GPS (Global Positioning System) was brought along with the camera to record where the photos were taken so the photos could then be linked to geographic coordinates.\u00a0 Once back in the lab, these pictures could be stitched together to form a seamless panorama and placed on a map with the attached GPS coordinates.<\/p>\n

Ryan walked us through a few camera basics to get us all up to speed with a basic level of camera aptitude.\u00a0 Each panorama, or series of six shots, was unique and everything had to be adjusted for that particular location.\u00a0 For each series of shots, we adjusted white balance, shutter speed, and focal point.\u00a0 The white balance was adjusted for sunny, cloudy, shady, fluorescent, or incandescent lighting.\u00a0 For most of our shots, we switched between the first three outdoor Kelvin levels.\u00a0 Shutter speed was probably the main variable that was changed for each shot, for it may still be sunny out, but the level of light and exposure that we wanted to capture would have been different.\u00a0 Shutter speed is measured in seconds or fractions of seconds, our particular camera having a range of 30 seconds to one four-thousandth of a second.<\/p>\n

\"RunningTrails\"<\/a><\/p>\n

There are three running trails on the campus of the University of Richmond that we photographed, the blue, the gold, and the red.\u00a0 These trails can be seen in the map above.\u00a0 In addition to the three running trails on campus, we also photographed the Gambles-Mill trail and the route you can take from it to the Huguenot Flatwater Park. The trail starts by running along the Country Club of Virginia golf course, eventually meeting River Road at the River Road Shopping Center.<\/p>\n

We crossed River Road over to Huguenot Road and followed it down all the way across the Huguenot Memorial Bridge. Then we followed the cloverleaf exit and took the left onto Riverside Drive and then a quick right onto Southampton Road to arrive at Huguenot Flatwater Park.\u00a0 Because each panorama needed to be about 20-30 feet apart and customized accordingly, even a simple walk around half the lake could take about two and a half hours to capture fully.<\/p>\n

In the coming week, we will be both stitching the photos together to form the actual panoramas and placing them on the basemaps with the geographic coordinates. We have tried a few so far and are still working out kinks with the process. However, the \u201cmess ups\u201d are pretty cool to look at!

This project was interesting to us not only because it helps an organization doing cool work, but the skills we are learning are very applicable to other projects we might do.\u00a0In terms of technological application, this project exhibits directly correlation to utilization in both Virtual Tours of Campus as well as a Virtual Tour Showing Students the way to Huguenot Flatwater Park.\u00a0 The virtual tour of campus would be beneficial for prospective students and especially for students that are unable to travel to visit the campus in person.\u00a0 Having a photographed route to Huguenot Flatwater could also encourage more students to make the trip down to Huguenot Flatwater Park.<\/p>\n","protected":false},"excerpt":{"rendered":"
