Remote Sensing Survey of Pecan Trees in Five Texas Cities    (View PDF)

L. C. Rodgers and M. K. Harris

Abstract: Canopy coverage of the total tree populations and pecan tree populations in five Texas urban areas were estimated and recorded based on an existing method of survey. This method utilized color infrared aerial photography in conjunction with the Universal Transverse Mercator grid system to inventory the trees and create a permanent data file for each urban area. Several modifications were made to increase the compatibility of the existing survey method to urban areas and to expand the amount of information recorded for each area. Analysis of the data collected was based on computer software programs, and the output was in tabular and graphical formats. Uses of these types of data files include landscape and city planning, surveys, and monitoring vegetation for disease or insect pest outbreaks.
