LIDAR Data
AnsweredHi,
I recently discovered that Vermont makes LIDAR data available on a mapping website, and it's invaluable for finding old manmade disturbances, like old logging roads. Is there a chance you could incorporate that into your databases?
Thanks

Hey Tom Wild,
Thanks for reaching out.
We don't have any plans to add Vermont's LIDAR data to Gaia GPS.
However, you can import nearly any map you find on the internet yourself. This article gives instructions for the different ways to import custom map sources:
Specifically, you can import this source by following these steps:
A number of the LIDAR data files are available here: https://maps.vcgi.vermont.gov/arcgis/rest/services/EGC_services
To import the hillshade data you would use this URL:
To import the contour data you would use this URL:
These URLs are generated by following these steps:- Open the WTMS GetCapabilities XML file
- Find the template in the XML file
-
Find the Style value which is "default"
-
Find the TileMatrixSet value which is "default028mm"
-
Update the template and set {TileMatrix}/{TileRow}/{TileCol} to {z}/{x}/{y}
- Copy & paste the URL from Step 5 into the custom map source import page
-
Update the coordinates in the preview map to somewhere in Vermont
-
Adjust the order of {z}/{x}/{y} until the tiles are displayed in the preview map
Click the "Help" button at the bottom of the screen if you have any questions. -
Can you answer a similar question regarding Creating a Custom Map Layer from USGS 3DEP Lidar? It's much higher resolution than the existing US Shaded Relief layers.
I found this, but don't see how to import it:
https://elevation.nationalmap.gov/arcgis/services/3DEPElevation/ImageServer/WMSServer?FORMAT=image/png32&TRANSPARENT=TRUE&VERSION=1.3.0&SERVICE=WMS&REQUEST=GetMap&LAYERS=3DEPElevation:Hillshade Multidirectional&STYLES=&CRS={proj}&WIDTH={width}&HEIGHT={height}&BBOX={bbox}
