The March NSS News, now newly available to NSS members at caves.org, has an article about using conventional LIDAR data to survey a cave. A considerably easier way to do that is described in an article in the Journal of Cave and Karst Studies at https://caves.org/pub/journal/PDF/v76/cave-76-03-

I've been LIDAR scanning caves here in Texas for the past 3 years with the Caveatron. Like the system in the article, you scan while moving through the cave rather than on a tripod, plus the Caveatron is like the DistoX in that you also use it to collect your survey data. The Australian system d

Not only has Joe done work in Texas, he has also come out to NM to assist our teams in Fort Stanton Cave where we made him wade through some water and mud to get back to Don Sawyer Memorial Hall, about a mile into the cave. His 3D data has complimented the 3D mesh of sections of the cave where w

Apologies to Alex and the rest of the NSS web team. When I criticized the speed of the NSS server, I wasn't aware that I had not completely revised my Internet access to my new place, and it had defaulted to a slower Wi-Fi when I restarted computer. Still, there is some hangup somewhere between

Bill, 2MB/sec is 2 megabytes per second, or 16 megabits/second. Older wifi (802.11b) has a theoretical max of 11 megabits/second, but you can rarely get that high. Newer wifi (802.11g - 54mbit, n - 600mbit, ac - 1300mbit) can go higher, but there are a lot of things that can interfere, especially

I thought that perhaps Shrewsbury had misspelled the name. I inquired and received this reply: /Hi Sam, It is Bob Thrun, of Maryland, and a caver who primarily pushed stuff in West Virginia. Bob Thren, as you know, is another person. Wm/ Now, does anyone know whatever happened to Bob Thren?

Charles (only)-- Thanks. I now get ~2MB/sec from NSS, which is good enough. Time-Warner's (Spectrum's) own speed test gives me 70 Mb/sec download and 10 Mb/sec upload. My current Wi-Fi router is using 5G, whatever that means, but the large number of other Wi-Fi hubs in the area may be cluttering

I remember Bob (Thrun that is) from what seems to me like the dawn of time. During the mid to late 60s the Washington DC area cavers were an odd lot, lots of CIA spooks and autistic technogeeks like Bob. He took caving very seriously and was methodical in all matters. Having a peach imspedi
