Title: B.L.M. balloon photography
First published: 1996
Description: Published in 1996, by then Graduate Student and USDOI Bureau of Land Management (Oregon State Office) Cartographic Technician Eric Stone III.  The Technical Memorandum describes the BLM's uses of low impact, low altitude aerial balloon photography for the capturing, archiving and resource management of endangered species sites and at risk archaeological and anthropological sites throughout Oregon and Washington.  Although now dated, the material is pertinent for all Tribal and Resource managers interested in documenting and preserving sites of interest.
The book provides several stereo pair examples of the photogrammetric projects performed by the balloon throughout Oregon and Washington of various sites both biotic and man made.  It also strives to differentiate between the utility of balloon photography with fixed wing and rotary (helicopter) photographic platforms.

Eric Stone III, LSIT GISP RPP, is a Licensed Registered Professional Photogrammetrist with the State of Oregon, and worked for 5 years with the BLM OSO, 5 years with Washington County OR and 9 years with USDOE Bonneville Power Administration.
