The focus in this article is on the way the post eighteenth-century cartographic turn in military practices developed into a particular military perception of landscape that continues to set the standard of Danish topographical mapping. My argument is that the development of modern topographical maps is the result of a long process of military comprehension and measurement of the terrain in order to conduct field operations. The demand for spatial data for actual or potential military operations had a direct impact on the specifications of maps produced by the military, as landscape representation was adapted to meet operational demands and as lessons learned from war experience were incorporated. In this and other respects, the development of Danish topographical maps in and after the nineteenth century followed the general trend of European military mapping as regards methods and standards. 相似文献

A time‐geographic approach, including time–space diaries and in‐depth interviews, is used to investigate the daily use and implications of information and communication technologies (ICTs) among a group of Swedish urban youth. We identify individual variations and nuances in ICT‐based practices in our respondents' social and spatial contexts. Using individual cases and detailed time‐geographic trajectories, we demonstrate how daily communicative actions – physical and virtual – are combined and integrated. From this we identify four ideal types of mobility practices: (i) home‐oriented, heavy Internet users; (ii) physically mobile, heavy mobile phone users; (iii) physically mobile, heavy Internet and mobile phone users; and (iv) home‐oriented, rarely mobile people (virtually and physically). 相似文献
