Deutschland hat ein umfassendes und in der Praxis bew?hrtes Planungssystem einschlie?lich integrierter Umweltprüfung, das
auch für zus?tzliche bzw. erweiterte Prüfinstrumente günstige Voraussetzungen bietet. Das Fl?chenmonitoring in der Regionalplanung,
aber auch für die St?dte und Gemeinden in der vorbereitenden Bauleitplanung kann mit Hilfe einer gezielten Ver?nderungsanalyse
der Landbedeckung als ein Baustein eines umfassenden Monitoringsystems und zur Unterstützung des Nachhaltigkeitsprinzips verstanden
werden.
Da jedoch insbesondere für einen l?ngeren Beobachtungszeitraum kaum bzw. keine (digitalen) Informationen über die Landbedeckung
existieren, stellt die Auswertung von Satellitendaten einen L?sungsansatz dar. Inwiefern sich die semiautomatische Analyse
von Satellitenbildern als ein geeignetes Instrument zur Bewertung und Ver?nderung der Nutzung eines Landkreises eignet bzw.
worin Analyseprobleme sowie M?glichkeiten und Grenzen der Anwendung in der Regionalplanung existieren, soll im folgenden Beitrag
am Beispiel des Landkreises Osnabrück thematisiert werden. 相似文献

Thanks to advances in technology such as Internet-based mapping and the development of special inks, papers and global positioning systems, map making for vision impaired people can provide a range of products (e.g., tactile, haptic and audio-tactile maps) that can improve their independence, self-confidence and everyday life. The applications of tactile maps include learning spatial concepts and geography; audio-tactile maps combined with access to geospatial information can enhance mobility and independence. In 1998, the Mapping Services Branch (MSB) of the Earth Sciences Sector of Natural Resources Canada initiated a tactile mapping program. Now referred to as the Government on Line—Mapping for the Visually Impaired Project (Natural Resources Canada 2003a), it aims to serve the community with special needs, with emphasis on those who are blind or visually impaired, their teachers and mobility instructors. This technical paper discusses the various types of tactile and audio-tactile maps of Canada developed by the MSB in cooperation with its partners and describe the current research and development activities carried out within the project. It also leads the reader to further information on audio-tactile maps and touch- and sound-based computer interfaces. 相似文献

The Charles Bridge is the oldest, still-standing gothic bridge that crosses the Vltava River in Prague and up to now has belonged among the most sought-after historical monuments in the Czech Republic. The bridge has been repeatedly damaged due to floods and has been repaired several times. In the reconstructions, damaged sandstone blocks were substituted in facing. This experimental study focused on nonlinear ultrasonic spectroscopy for testing stone blocks that were extracted from the historical bridge structure. The objective of these experiments was verifying whether the methods can be applied to evaluating the internal structure of blocks, which are built-in in the structure in situ. Intact-structure blocks, blocks that had been repaired in the past, and damaged-structure blocks were measured. Two methods of nonlinear ultrasonic spectroscopy were applied—the method with single harmonic ultrasonic signal and with two harmonic ultrasonic signals. Measurement results of both applied methods proved resulting parameters correlation with block structure integrity quality. 相似文献

The assessment of different urban planning scenarios by stakeholders can yield important insights which, in turn, inform sustainable urban transition. Yet to gain in-depth insight, this assessment needs to be multi-faceted and should go beyond a unidimensional “most/least desired” approach. Accordingly, we use indicators that distinguish between desirability, utility and probability assessments. We compare these assessments within and between various stakeholder groups based on a set of literature-based hypotheses. We constructed six planning scenarios, systematically varied with respect to sustainability for the case study, “Erlenmatt”, a major urban redevelopment area in Switzerland. Three stakeholder groups (housing suppliers, the non-profit & public sector and housing target groups, n?=?80) were investigated. The results of the statistical analyses suggest that more sustainable scenarios are preferred with respect to both their desirability and utility and that their probability is not lower than that of the other scenarios. The non-profit & public sector is the most pessimistic about the probability of a sustainable district while housing suppliers desire it less. We conclude that such detailed subjective scenario assessments can provide informative and detailed guidance for sustainable urban transition. 相似文献

Based on a newly constructed set of data, this paper offers a quantitative perspective on the Nationalist Government’s relations with China’s domestic bond markets during the period 1932–34. For all the recent revisionist scholarship on the achievements of Nationalist state-building, the perception of the Nationalist elite as corrupt is still widely accepted. In order to demonstrate the empirical potential of quantitative financial history, this paper tests one particular assertion: that members of the Nationalist elite manipulated the issue price of domestic government bonds in order to enrich themselves and their associates. We test this by calculating two price data correlations: that of a first sample of government bonds, all of them issued before 1932, and that of a second sample of government bonds, which includes bonds issued during the period under review. The price fluctuations of the first sample are correlated with each other to a much higher degree than those of the second sample. This indicates that the prices of bonds in the first sample were reacting similarly to the same range of influences, while the bonds issued during the period under review and included in the second sample were displaying individual price fluctuations. One possible explanation for this is that members of the Nationalist elite enriched themselves or their associates by issuing domestic government bonds at artificially low prices. In sum, the article illustrates both the potential and the limitations of quantitative history: it allows us to test and dismiss a precisely formulated hypothesis about Nationalist corruption, but it is only one possible way in which statistical analysis can be applied and does not cover the whole realm of state practices. 相似文献
