Zur geowissenschaftlichen Interpretation kosmicher Aufnahmen aus dem ostlichen Harzvorland. (On the geoscientific interpretation of spatial photographs of the eastern piedmont of the Harz mountains)
Partial aspects of the regional structure of the eastern piedmont of the Harz Mountains are analysed by means of interpreting spatial photographs. The possibility of making in regional analysis of certain territorial phenomena by means of spatial
photographs is significant| e. g. the discovery of linear geostructures, the mapping of topical regional structures of the territory and the observation of topical variations in the distribution of territorial phenomena.

Soil surface infiltration capacity classification based on the bi-directional reflectance distribution function sampled by aerial photographs. The case of vineyards in a Mediterranean area

Soil surface infiltration capacity classification based on the bi-directional reflectance distribution function sampled by aerial photographs. The case of vineyards in a Mediterranean area
surface pixels were automatically extracted from high spatial resolution scanned aerial colour photographs.
The AA. propose a remote sensing based method to map vineyard soil surface features with a spatial and temporal resolution appropriate for integration into the model. The aim was to classify each soil surface portion in accordance with a pre

Maps from 1904 and 1915 and air photographs from 1963, 1980, 1985, 1993 and 1996 provide a record of landslide incidence in a 92.1-km2 drainage basin, a headwater tributary of the Cho-shui River in Taiwan. Interpretation of landslide patterns from
the early maps indicate that in 4 sub-basins structural geological factors control chronic landsliding regularly reactivated by intense rains. Within these 4 sub-basins, all later air photographs reveal a continuing high incidence of landslides. Logging

Measuring bluff erosion part 2 : pairing aerial photographs and terrestrial laser scanning to create a watershed scale sediment budget

Measuring bluff erosion part 2 : pairing aerial photographs and terrestrial laser scanning to create a watershed scale sediment budget
at the watershed-scale. Despite different spatial and temporal measurement scales, the aerial photograph and TLS estimates yielded similar results for bluff retreat rate and total mass of sediment derived from bluffs, with bluffs in the Le Sueur watershed yielding
The AA. aim to determine the magnitude of erosion from tall bluffs, in the Le Sueur watershed, Minnesota. They coupled analyses of 7 decades of aerial photographs with 4 years of repeat terrestrial laser scanning (TLS) to determine erosion rates
on bluffs. Erosion rates from aerial photographs and TLS were extrapolated from 243 and 15 measured bluffs, respectively, to all 480 bluffs in the Le Sueur watershed using multiple techniques to obtain estimates of sediment loading from these features

Lightness and weight : (re)reading urban potentialities through photographs

Lightness and weight : (re)reading urban potentialities through photographs
Capturing images is entwined in a complex web of associations, linking the epistemology of research practice with the perceived nature of evolving spatial processes. One example of this is the way urban geographers use images to document

This study employs data from valley-bottom surveys, coring investigations, topographic maps, and aerial photographs to identify and explain spatial variations in historical alluviation along tributary streams in the Buffalo River watershed
, an agricultural watershed in west-central Wisconsin. Similar to findings from other agricultural watersheds, the spatial distribution of historical alluvium in the Buffalo watershed reflects the controlling influence of watershed size and valley-bottom width

The A. reviews some present-day characteristics of geography and gives some suggestions. The landscape should be understood as a mosaic and very detailed measurements are recommended to solve the special spatial features. On regional geography
should be given more attention. The teaching of geography in schools should be developed. Maps, aerial photographs and satellite data give a strong base for studies of environmental change and should be used by geographers. Cartographic skills have

The use of remote sensing and landscape metrics to describe structures and changes in urban land uses

The study introduces a methodology using information on image spatial form to describe urban land-use structures and land-cover changes that result from urban growth. The analysis is based on spatial analysis of land-cover structures mapped from
digitally classified of aerial photographs of the urban region Santa Barbara, California. The results show a useful separation and characterization of three urban land-use types : commercial development, high-density residential, and low-density residential
. Several important structural land-cover features are identified. For two test areas in the region, changes in the urban spatial land-use structure can be described and quantified with landscape metrics.
