- Switch to street view
- Zoom in to the area
- Use blue pencil icon, and outline the box you want
- Add data sets to the cart. Insure you only get ones that say LIDAR, and not those that say DEM.
- If the files are too large, restrict the area.
- Go to the cart
- Hit next
Bulk download takes you to a page with a listing of all the files, which you can edit and download, but it will be less convenient than going through the cart.
Projects list:

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, but you will have to get the decompressor and place it in the correct directory. If you get LAS the files will be zipped, which is less efficient that LAZ for lidar.
- 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?
When you download, put each data set in its own directory, and carefully name it.
