Relationship of properties to formation
factors.• Soil forming factors
– climate
– parent material
– topography (relief)
– biologic (vegetation)
– time
• Soil properties
– texture
– drainage
– fertility
– depth (to rock)
– *water holding capacity
– *strength

LiDAR Links for Maine:
Elevation Discovery App: http://www.maine.gov/geolib/ediscovery/site/index.html -allows user to download dem grid files
Imagery Discovery App: https://www1.maine.gov/geolib/imgdiscovery/site/index.html- allows user to download tiles of High Resolution Leaf Off Imagery 2012-2016 (not full state)
Other Maine Data: https://geolibrary-maine.opendata.arcgis.com/# - new service, still in the process of moving data.
MEGIS Data Catalog: http://www.maine.gov/megis/catalog/ - older service, has some 2ft contours, but hasn’t been updated for awhile.

Also:
https://viewer.nationalmap.gov/basic/
This site allows point cloud downloads (rather than bare-earth dems). Why? Can create derivatives for canopy height.
