GPS Mapping: Kramer Tree Specialists now offers Global Positioning System (GPS) technology to locate plants accurately on a property. This service creates an aerial view site map with specific locations of all trees and buildings, and can include sidewalks, driveways, fences, or any other structures on the site. Documentation of the history of the trees (treatments implemented, pruning completed, overall health status) can be tracked with bar-coded tree tags. This is a new service, which, in the coming years will become a more standard procedure.
