Air photo interpretation for the measurement of changes in urban land use
This research is concerned with the use of aerial photographs for the measurement and recording of urban land use. A suitable land use classification scheme and a methodology for the measurement and recording of land use areas are developed. Use is made of these to obtain data for geographical …

Applications of air photo interpretation techniques in the Langebaan area, S. Africa
… includes the particular benefits of colour air photographs, the relationship between scale of survey and scale of mapping and remote sensing products, and more information about the 'semi-detailed' level of survey operation. The latter is the category of survey which the vegetation survey of the …

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 …

Using Lidar Data to Predict Photo Interpreted Attributes
… datasets and robust workflows exist for both the photo interpretation and Lidar methodologies. Both methodologies have unique and non-overlapping strengths in describing forest conditions. Bridging the data products of these methodologies would expand the capabilities for both approaches. To my …

Estimation of seedling density and evaluation of woody competition in young loblolly pine plantations using 35mm color aerial photography
… 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 and …

Suitability of Aster and SRTM dems, and satellite imagery in detailed geomorphological mapping in Dzanani Area of Makhado Local Municipality, Limpopo Province, Republic of South Africa
… mapping. Field survey and aerial photo interpretation were used to prepare a reference geomorphological map for comparisons. A similar approach of demarcating landform boundaries from aerial photographs was implemented to segment the DEMs into landform classes. The software …

Vernal Pool Mapping and Geomorphology in the Appalachian Mountains of Pennsylvania
… suitability model and leaf-off aerial imagery interpretation. Four terrain rasters derived from a 1-meter DEM (modified wind modified wind exposure, terrain surface convexity, topographic position index, and a multiresolution index of valley bottom flatness) were used in the suitability model. …

Riparian willow dynamics and their interaction with environmental and biological factors in the elk winter range of Rocky Mountain National Park (Colorado) - a multi-scale analysis
… change analysis of willow cover was conducted by photo-interpretation of historic (1937/1946) and recent (1996) aerial photos. A decrease of willow cover of approximately 20% and more than 50% reduction in river length and water surface area were determined in this period. Deeper water tables that …

Application of Ancillary Data In Post-Classification to Improve Forest Area Estimates In A Landsat TM Scene
… of satellite technology in relation to aerial photo-interpretation, finding the satellite method to do an adequate job, but reporting over-estimations of forest area. This research extends the satellite method a step further, introducing the use of ancillary data in post-classification. The US …

Remote sensing applications in vegetation mapping with special reference to the Langebaan area, South Africa
Interpretation of remote sensing products as a procedure used during the process of vegetation mapping has developed from a purely visual process of image identification to one which can utilize computerised methods to aid consistent identification of vast quantities of digitally stored/recorded …
