Measurement of plant community cover from aerial photographs using Ektachrome Infrared Aero Film

Color-IR aerial photographs of arid-zone vegetation have been used to estimate the amount of green plant material on the ground. The purpose has been to estimate plant cover as it varies with time and space and relate this vegetative measure to hydrologic conditions. Aerial photographs of the 6000-acre target area were taken periodically over a period of 3 years. Results of densitometric analyses are presented.

Studies in short haul air transportation in the California corridor: Effects of design runway length; community acceptance; impact of return on investment and fuel cost increases. Volume 2: Appendices

The development of a forecast model for short haul air transportation systems in the California Corridor is discussed. The factors which determine the level of air traffic demand are identified. A forecast equation for use in airport utilization analysis is developed. A mathematical model is submitted to show the relationship between population, employment, and income for indicating future air transportation utilization. Diagrams and tables of data are included to support the conclusions reached regarding air transportation economic factors.

Service to Small Communities

The problems involved in the operation of low cost local service air carriers are analyzed. Four specific situations which created the operating difficulties of the local air carriers are defined. Proposals of federal and local subsidies for short haul air transportation are presented.
