Use Of Small Format Aerial Photography in NPS Pollution Control Applications
An automated procedure was developed to identify and extract confined poultry facilities from color 35-mm slide imagery collected by the United States Department of Agriculture/Farm Service Agency (USDA/FSA). The imagery is used by the USDA/FSA to monitor compliance with various farm support …

The applications of aerial photography, photogrammetry and photo-interpretation in the planning process
To date aerial photography and associated photogrammetric and photo-interpretation techniques have played but a limited role in the planning process. In this study their dual role (i) as a base medium and (ii) as a source of data is investigated bearing in mind the requirements of planning data and …

The potential use of 35mm aerial photography in planning a selective mechanized thinning
… physical and economic feasibility of using 35mm aerial photos to space access corridors for thinning two overstocked loblolly pine plantations in the piedmont of Virginia. Tree diameters at groundline were predicted as functions of photo-measured crown areas. The capacity of the accumulator on …

Topography and flight: The creative application of aerial photography and digital visualisation for landscape heritage
Aerial photography and digital visualisation technologies are commonly used to reveal and interpret archaeological sites and landscapes. These methods afford a clarity and overview that has considerable advantages in heritage visualisation. Despite this, both technologies offer a view that is …

Recontextualizing Military Structures along the Stanegate and Hadrian’s Wall Utilizing Aerial Photography and GIS Mapping
… their relationship to the Wall and each other. Aerial photography and the construction of a geographic information system (GIS) can prove a valuable tool in surveying the region, to extract data from forts, camps, and recently discovered land depressions. Measurements can be taken to determine …

A Vegetation Analysis on Horn Island, Mississippi, ca. 1940 Using Characteristic Dimensions Derived from Historical Aerial Photography
… year period using historical black and white photography from 1940. Using present NAIP imagery from the USDA, habitat structure was estimated by using geo-statistics, and second order statistics, from a co-occurrence matrix, to characterize texture for habitat classification. Percent land …

Assessing Efficacy of Restoration Treatments in Juniper Savannas using Spatial Wavelets and Dot Grids on Aerial Photography
Across much of their diverse natural range in the Western US, species of the genus juniperus are expanding onto open grass and shrublands and infilling open woodland areas. In Southern Arizona’s Clifton Ranger District, landscape-scale restoration treatments have been used to stall this expansion …

Estimation of seedling density and evaluation of woody competition in young loblolly pine plantations using 35mm color aerial photography
The potential for using large scale, small format aerial photography to obtain seedling density and woody competition information was investigated. Factors affecting photo interpretation of seedlings were examined and equations to predict seedling density and woody competition levels were developed …

Integrating Digital Aerial Photography and Lidar-Derived Information For Object-Based Coastal Tidal Marsh Classification Using Tree-Based Ensemble Algorithms
… evaluated the capability of color-infrared (CIR) aerial photography integrated with high-posting-density LiDAR (Light Detection And Ranging) data for intertidal vegetation classification in the upper May River watershed near Bluffton, South Carolina. An object-based image analysis (OBIA) approach …

Aerial photography and environmental impact analysis : the potential contribution of comparative interpretation of multi-temporal aerial photographs to Environmental Impact Analysis
… comparative interpretation of multi-temporal aerial photographs can be used as a tool in Environmental Impact Analysis (EIA). To test this hypothesis a site, Silwerstroomstrand, approximately 40 kilometres north of Cape Town on the West coast was chosen. An analysis of the site was carried out …

Using Archived Aerial Photography to Measure Long-term Change in the Surface Elevation of Larsen A Tributary Glaciers from 1957 to 2020
… geographically accurate DEMs from archived aerial photographs obtained in 1957 and 1995, where in situ GCPs are limited or non-existent. Historic DEMs were used alongside the REMA DEM to measure change in ice elevation, pre and post the collapse of the LAIS. It was determined that glacial …

The hermeneutics of airphoto interpretation
… the cultural and political applications of aerial photography. The thesis emphasizes the historical development of aerial photography technologies and the incorporation of these systems into national policy. The Majority of the discussion details the U-2 reconnaissance program. There is an …

Textural Analysis of Historical Aerial Photography to Determine Change In Coastal Marsh Extent: Site of the Present-Day Grand Bay National Estuarine Research Reserve (GBNERR), Mississippi, 1955-2014
… loss or gain in marsh area is through the use of aerial image data, which offers synoptic views of the landscape at decadal-scale sampling frequencies. However, a potential problem with older panchromatic, or black-and-white, imagery is the absence of multispectral information that might be used …

Landscape level raptor habitat associations in northwest Connecticut
… white and 1:58,000 and 1:126,000 color infrared aerial photography. Among-species nest area analyses at the ground level indicated that higher beech and red maple densities were associated with red-shouldered hawk nest areas than with nest areas of barred owls or northern goshawks. Analyses …
