Weather archive updates

We collect imagery from national park webcams in the Great Smokies and Mammoth Cave parks and then make animated gifs of those webcam images. In 2011, I penciled this quick note:

110629 Nice time-lapse photography for all cameras and satellite. Make movie?

Beginning in 2012, we started archiving these animations.

New webcam added to animation archive

Turns out, we had Mammoth Cave working for the entire 2021 year, but didn’t have them accessible via a web page. With a little grep and sed action, the gifs were added to the default page for the Great Smokies archive. Visit the interface here.

Weather and animation archive

We plan on having at least the last year covered in the archive. At 60 GB a year now with HD cameras, it can get expensive hosting multiple years. I do have the years back to 2012 stored offline.

New Red River Gorge map

Over the past spring, we’ve been revamping our popular map for the Red River Gorge. The map should be available in early June. One of the additions is a new Bird’s Eye View map that user lidar elevation data and Blender 3d modeling software. You can view a zoomable image with this link

2020 Census data

Time to explore the data on a map. The experiment is show block group data for select demographic data, which was used for redistricting. This interactive presentation is a test of concept to show population density. Eventually, an UI element will be added to symbolize block groups by precent population in self-identified racial group – as defined in Census categories.

Custom shaded relief maps

After a few weeks fiddling with the Blender 3D application to make smooth shaded reliefs, I decided to create raster tilesets that could be used with web mapping applications for a unique look. While the shading is not as accurate as multidirectional shading techniques used in GDAL and ArcGIS Pro, it makes a more artistic rendering.

An archive of message boards

phpBB

Back in the early 2000s, this popular messaging board (and others like it) was where online interaction happened. Many were focused on local groups and activities. Then, Facebook, spambots, and more dangerous hacking emerged. These boards couldn’t keep up and users eventually found more immediately gratifying social media platforms.

I have taken two popular boards and retired most of their functionality. One can view posts, but cannot add new ones or search (sorry).

Having fun with lidar

Lexington has a awesome fall event called, Paint by Nature, which encourages folks to create artwork around notable trees in the city. These trees aren’t necessarily the largest or showiest in their area, but are highly suitable plantings for their ecological settings.

While I didn’t make a submission, I did map the trees and used various lidar sources to visualize them. Visit this 3D visualization powered with Potree point cloud renderer. A growing list of similar visualizations can be found here.

Sheltowee Trace elevation profile

Working on the 2020 update of the Sheltowee Trace maps using high-resolution DEMs derived from lidar point clouds. An elevation profile was created by sampling elevation every 264 feet along the 343-mile trail. This profile shows the proposed extension from Burnt Mill bridge to Rugby.

The resolution is high enough to see the indentation of wider trail beds, which helps verify GPS data.

The updated trail maps should be at the printer by mid-July.

Fishing Rock Creek

Great Meadows camp sits along the banks of Rock Creek, a Kentucky designated Wild River and is stocked with fish almost monthly. A short hike along the Sheltowee Trace takes one to Hemlock Grove, a stately picnic area. The campground can serve as a point of entry for the John Muir Trail and the old homesteads found along the tributaries of the Big South Fork.
