Digital analysis of remotely sensed images for evaluating color in turfgrass

Creator:

Friedkin, William C., 1954-

Abstract:

Most conventional approaches to rating turf color for different turf varieties grown under similar conditions or for the same variety grown under different cultural conditions employ a visual subjective rating. By digitizing remotely sensed images acquired by use of a helium filled blimp and a Canon EOS camera, we were...

Photogrammetric uses of a new-generation analytical stereoplotter in forestry

Creator:

Kiser, James D. (James Donald)

Abstract:

The development of personal computer software coupled to an analytical stereoplotter allows major gains in efficiency and accuracy in a number of forestry related subjects. This thesis describes the operation of a system developed by Carto Instruments. This thesis demonstrates how area estimates might be made in a systematic way...

A Methodology to directly input data from an uncontrolled aerial photograph into a vector based geographic information system

Creator:

Sneed, Jacquelin M.

Abstract:

Historically the U.S. Forest Service has used uncorrected aerial photographs to delineate proposed and past management activities on the land base it manages. Transferring a boundary from an image not planimetrically correct to a planimetrically corrected image introduces errors. Positional accuracy of boundaries affects the number of acres the Forest...
