Interesting Gabe. On the regular aerial, are there any roads or trails leading to it? Is that the edge of a hard road I see in the upper left corner?

Reminds me of this, but probably smaller?

I mentioned it in the sand pit thread, but this was the original:

Did you ever figure out what that is?

It's strange to me that the 2019 lidar is so much more detailed than the lidar found in boydsmaps, yet things show up in the latter that don't show up in the former. Why is that?

Bob, that's a dirt road you see. Here's the 1931 aerial. Notice the path going right through the center of the feature (the feature is where the target is).

The 2015 1-meter LIDAR only covers Camden, Burlington and Gloucester Counties. My old map used the older 3-meter (1/9 arc-second) LIDAR for all the areas that are covered by this new 2019 LIDAR. That is a huge difference in resolution. Imagine a little shed that is 10 feet x 10 feet. It would be represented by one pixel on the 2015 LIDAR. There would be 9 pixels representing the same shed on the 2019 LIDAR - quite a difference when looking for details.

Right, but why is it that certain trails show up on the lower resolution lidar but not on the higher reolution images?

...And I should also add that the 2019 LIDAR actually has a resolution of 2 feet per pixel, so my earlier example was too conservative - it would be more like 25 pixels representing the 10 ft shed. However, I have down-sampled it to 1-meter to match the 2015 LIDAR and to keep the size of my new map reasonable.

Surprise!... LIDAR in the Pines 2021 (Monochrome Edition) is now available at mobile.boydsmaps.com :dance:

I'll still be releasing another map with roads, waterbodies, etc but this was pretty straightforward when I finally finished preparing all the elevation data. It's rendered in a style similar to the NJGIN map, but I tried to bring out more detail by using more vertical exaggeration, a lower light angle and less intense highlight.

The map consists of 1-meter (or better) resolution LIDAR DEM for everything South of I-195 plus parts of PA and DE bordering the Delaware River. This combines my existing data from LIDAR in the Pines HD, the new South NJ 2019 LIDAR and I also downloaded quite a bit of additional USGS 3DEP LIDAR to fill in all the missing puzzle-pieces.

Although the mobile site is optimized for smaller touchscreens, it works fine on computers. You might reduce the size of your browser window for a better experience. Use the right mouse button to tilt and rotate the map in 3d, you can return to standard north-up view by clicking the compass. To link to a specific map view, press the menu button and choose Export.

I have not decided whether to put this map on the desktop site, which is basically frozen until I complete the mobile site. At that point, the desktop app will be completely updated to use the same 3d Maptalks API and my custom code.

Note: I'll be shutting down the 2019 LIDAR Viewer site that was temporarily created since you can now fully access these maps.

Super-dooper. Thanks Boyd.

Thanks again Boyd! especially for putting coords to it. Makes locating tar kilns much easier then trying to match different aerials which works but takes a bit of time and head banging in areas where there are no notable trees or tree patterns.

I went ahead and added this map to the desktop site as well, since it will be awhile until I get around to the major update there. The desktop site uses a different API which will allow you to "overzoom" the map to level 19. This does not add any more detail, it just magnifies the level 17 map, but it can help bring out small details.

Al,

The Hillshade Lidar site allows you to get coordinates. Just click on "Measure" and then click on the square icon next to the ruler. Once you click on the map at any location the coordinates show up. You can also change it to DMS.

Hmm.. won't load on desktop for me.
