Just think, if you were walking around when they lidar-scanned an area, the beam would go right through you, hit the ground, and be reflected back up through you again. But I suppose that's nothing, compared to all the cellphone, wifi and other electromagnetic radiation that passes through our bodies all the time. It is food for thought however....
Cranking out map tiles again! I had reached the limit of my topo dataset and had to spend awhile building a larger, regional map that will meet future needs. This new batch of 20 tiles covers the approximate area from Maple Island, East to Atsion Lake.
Just added 19 new tiles. This completes the Southern part of the map - for now - here's the updated coverage. The "notch" below Atsion is the missing Atlantic County data. I went on the USGS website, and unfortunately they still don't have any 1-meter LIDAR for either Atlantic or Ocean Counties. Considering current events, I'd be surprised if we get that anytime soon, but I'll keep checking from time to time. Next, I'll complete the area Northwest of Atsion, then will extend the whole map farther North.
BTW, if you aren't familiar with the new LIDAR site, here's a quick tip. When you go to a link (like the one above), hold down the RIGHT mouse button and drag. Do NOT hold the left button. When you drag with the right button depressed, you will "fly around" ("orbit") the location marked by the crosshairs. This helps you understand what objects look like in three dimensions.
Here's a little "bonus", since some people are anxious to see a certain part of Atlantic County. This shows the full extent of the LIDAR data that is available in the area South of Batsto. I'm disappointed that we don't have Atlantic or Ocean County too, but making partial map tiles that would need to be replaced later just doesn't make sense. Sorry.
If you click these images, you can click the little magnifying glass at the upper right to view them at full resolution. There's also a button there to download a copy at the full 1-meter resolution (which is approximately 2460x1900 pixels).
Boyd I haven't had the chance to really look at your LIDAR site till a few days I sat down and figured it out.It's Awesome! Thanks,I know this is taking a lot of time and probably aggravation. Are you planning to come "Down Under" with it or just doing the Core? In any case thanks.It's a great tool for finding things to explore!
Thanks Al! Of course I want to go "down under". But if you have not followed the discussion, you may not have noticed: there is no 1-meter LIDAR data for Atlantic or Ocean County. The older 3-meter LIDAR is a completely different thing, and I'm not going to use any of that on the new site. So, I will just continue the work on Burlington and Camden Counties.
I really don't know, but given the current situation, I'd be surprised to see any Atlantic or Ocean County data for awhile. I hope the Federal Government is allocating their money and staff to more vital things right now.
Sorry Al, this is all I've been able to find so far. Those "swiss cheese" holes in Camden and Gloucester could be something I missed. Don't know for sure, but had a look on the USGS site about a week ago and didn't see anything new. Almost all of it is part of a big "Delaware Valley" LIDAR project.
So far, I have made a total of 667 tiles. There are four maps (elevation, topo, aerial and shader) for each tile, so that's 2668 individual files - each one is "hand made". It'll be a long time before I get out of Burlington and Camden Counties.
