Thermo-topographically induced winds in the boundary layer over the Etosha Pan
Boundary layer winds over the Etosha Pan in Namibia reveal a diurnal oscillation. An analysis of this phenomenon is presented with relation to synoptic forcing and thermo-topographical forcing. - (AJC)
Towards a definition of topographic divisions for Italy
This paper presents a preliminary subdivision of the entire Italian territory into formal topographic units and describes the rationale and the largely DEM-based techniques by which it was prepared. The classification is semi-quantitative, derived
The use of topographic scale models in predicting eolian dust erosion in hilly areas: field verification of a wind tunnel experiment
Eolian erosion of natural dust in an area of 53 ha, situated in the northern Negev Desert, is investigated both in the wind tunnel (erosion simulations on a topographic scale model) and in the field. The wind tunnel results and the field results

to topographic and thematic maps and reports from various practical projects in order to illustrate the main points. Finally the future dimension of remote sensing cartography within the field of developing geographical information system (GIS) is pointed out.
Streamlined, oval-shaped, oriented topographic highs in Massachusetts Bay are identified as the erosional remnants of drumlins. The topographic highs correlate with outlines of lag gravel deposits on the sea floor and both the highs and lag gravel
Alluvial fan deposits in two areas of the Blue Ridge Mountains of Haywood County were mapped and subdivided into three relative ages (young, intermediate and old) on the basis of topographic position and weathering characteristics. The mapping
Relationships were examined between topographic gradients, vegetation types, and values of the normalized difference vegetation index (NDVI) at the alpine treeline ecotone within Glacier National Park (GNP), Montana, and Rocky Mountain National Park
dynamic inundation zones. In particular, this paper demonstrates that reasonable predictions may be obtained on the basis of extremely sparse data sets, such as topographic maps and available flow monitoring records.
The relation between morphological change and patterns of variation in bedload transport rate in braided streams was observed by repeated, daily topographic surveys over a 25 day study period in a 60 m reach of the proglacial Sunwapta River, Alberta
topographic mounds upslope of the tussocks which are interpreted as deposition bodies originating from the interception of downslope sediment movement by the vegetated patches. A simple simulation model has been built from the field observations.
Methods are presented to integrate satellite data into the Authoritative Topographic and Cartographic Information System (ATKIS). At first, the government surveying data retrieved from ATKIS is used as additional information to improve remote
