has descriptions of the layers, and you can download from the description.

Suggested settings on checkout:

Get the point cloud for flexibility; you can create a grid in MICRODEM from the point cloud. If you do want a grid, get "Raster: as the output product, and pick the 32 bit Geotiff.
Get everything in meters.
Get NAD83. If you get WGS84, the vertical datum will be WGS84/ITRF94 Ellisposoid, which will probably not be useful.
Get LAZ for files about 10% the size of the LAS. You can Decompress after download.
Get all data classes.
Copy choices from one dataset to another by highlighting the second data set on the left, and then using the drop down box in the upper right. Check very carefully that all settings are correctly set (we have had issues with the data classes).
Do not hit Next until all choices are set for all data sets. There is no back button on the next screen.

You will get an email when the data is ready. Problems with download?

Tiles are named either as quarter quads or a smaller variation.
- Quarter quad naming is YYXXXyx indicating the southeast corner location where
- YY = integer latitude
- XXX = integer longitude (positive west)
- y = a letter (a-h) representing 1/8 degree of latitude (a = 0, h = 0.875).
- x = a number (1-8) representing 1/8 degree of longitude Thus, quarter quad 42082b5 has its southeast corner at 42.125N 82.5W.
The scheme for smaller tiles is YYXXX_yy_xx, where
- yy = hundredths of a degree of latitude
- xx = hundredths of a degree of longitude Thus, tile 42082_12_50 has its southeast corner at 42.12N 82.5W.
Only tiles with data are included.
