The spatial analysis literature recognizes three sources of aggregation error, termed Source A, Source B, and Source C, which affect models relying on distance measurements between populations and facilities. We consider these effects with respect to aggregating from census enumeration areas to census tracts, on a popular location model. We identify a further source of aggregation error, which we dub Source D error, arising from the representation of facility sites by discrete points. Source D effects are of the same magnitude as Source A and B combined, much greater than Source C effects. Source D error is further significant, because, unlike Source A and B error, it can be eliminated only by disaggregating .
La littérature sur Vanalyse spatiale reconnaît trois sources d'erreur d'agrégation appelées erreurs de source A, B, et C. Ces erreurs influencent les modèles qui reposent sur des mesures de distance entre des populations et des installations. On considère les effets d'agrégation des secteurs de dénombrement en secteurs de recensement sur un modèle de localisation courant. On identifie une quatrième source d'erreur d'agrégation appelée erreur de source D. Cette erreur découle de la représentation des sites des installations par des points discrets. Ses effets sont du même ordre de grandeur que ceux des sources A et B combinées et beaucoup plus grands que les effets de source G. L'erreur de source D est d'autant plus significative à cause du fait que, contrairement aux erreurs de source A et B, elle ne peut être éliminée que par la désagrégation . 相似文献

This paper analyses the relationship between spatial dynamics of firms and employment growth in the region. Moreover, it addresses the facilitating or impeding role of (new) industrial sites in the geographical process of firm and job dynamics, while recognising that the spatial dynamics of firms reflect socio‐economic developments at both the regional and national level. To this end, a novel conceptual theoretical framework based on the so‐called flow approach, is developed, through which the relationship between spatial dynamics of firms (entries, exits and relocations) and changes in regional employment (job creation and job destruction) can be systematically analysed. Moreover, it also allows us to assess the generative employment effects of firm moves from and to (newly created) industrial sites in the region. To demonstrate in practice the usefulness of this new approach for the regional employment effects of spatial firm dynamics (facilitated or hindered by industrial site developments) an empirical application to the area of Amsterdam‐North (the Netherlands) will be presented. 相似文献

In this paper data is presented that gives indications that Fryslân, being the only minority language region in the Netherlands, can be considered to have a distinct regional economy in the Dutch context. Therefore, information is given about the extent of regional identification in business names all over the Netherlands. Reference is made to the theoretical work of Rose and the empirical investigations of Zelinsky and Pellenbarg. Interviews in business firms in Fryslân are described. Fryslân appears to have a special position in the Netherlands in that there is a relatively strong identification by entrepreneurs with the province using the name of that region in business names but particularly by using the regional language, Frisian, for that purpose. There are strong indications that Fryslân also has a distinct regional economic development in the Dutch context because of the bilingual situation. The paper ends with an evaluation and with policy recommendations for the Provincial Government of Fryslân. 相似文献

The use of georeferenced data in geographical research into unemployment reveals internal fluctuations and differences within localities. The observation unit in the present paper is a 1x1 km grid cell. The results obtained here indicate that the rate of unemployment in Finland during 1993–95 was highest in the most sparsely populated cells. The duration of unemployment in 1993 was longest in the centres and suburbs of major cities, and it was also very long in the most sparsely populated cells. In the largest ten cities, the areas with the highest unemployment rate mainly remained the same during 1989–96; more than 60% of the cells with the highest unemployment rates in 1989 also fell within the same quartile in 1996. Restricting the availability of grid‐based information would have a contrasting impact on analysis. If data on cells containing five people or fewer had not been available, it would have meant a loss of 42.3% of the total inhabited cells and a 2.4% loss in population. 相似文献

In this paper a relational view on industrial location theory is put forward. Such an approach implies that site selection and suitability should be defined and modelled as a matching problem. It involves taking into account the links between the spatial production requirements of an economic activity and the characteristics of a potential production environment. Apart from introducing various model building requirements, an adequate relational matching formalism is advanced. In this respect, use is made of the decision table approach. 相似文献

古建筑三维重建已成为历史遗迹保护与修复的重要内容。为了探讨三维激光扫描数据的获取流程、数据处理方法,以三维激光扫描获取的大雁塔海量点云数据为例,研究了古建筑三维重建中点云数据获取与处理的详细过程。联合Cyclone、AutoCAD和3D-Max软件的优点构建了大雁塔真实的横面、剖面、立面模型,其中重点研究了海量点云数据在Cyclone软件中分块建模的方法。结果表明:将拼接好的大雁塔海量点云数据分块建模,不仅加快了数据处理的速度,而且符合精度要求。在点云数据拼接时采用标靶拼接和同名点拼接相结合及测站间两两拼接之后再整体拟合平差的方法,减少了拼接中的误差,使每站拼接误差都不超过3cm。在建模过程中的墙体拟合是上万个点云经过平差计算得到,精度高达2mm。最后在3D-Max软件中组合、渲染和贴图,真实地构建了大雁塔三维立体模型。为古建筑数字化存档和后期的修缮工作提供了重要的依据。 相似文献
