摘要： For topographic processing, a plurality of maps are stored, the maps being of different scales and therefore being based on different amounts of map data. The user selects a map of appropriate scale, and can then select a part, for example a line, on which appropriate analysis is to be made, such as obtaining a cross section based on contour data of the map. The map data corresponding to the selected part of the map is investigated and, where it does not meet an appropriate criterion, the data of a part of a map of different scale is investigated, the part of the two maps corresponding to the same region. Hence information can be derived which meets the appropriate criterion. Thus, when obtaining a cross section, if the amount of data for a region of a map is insufficient for a satisfactory cross section to be obtained, the data of the same region of a map of larger scale is analyzed, so that a satisfactory cross section can be achieved. The processing is also applicable to the investigation of lines of sight, using the map data.

摘要： A geographic information display control system displays objective geographic information using geographic data stored in a plurality of databases. A plurality of geographic data acquiring units instruct acquiring conditions, including a job script generated from a job selection, for acquiring the geographic data stored in the plurality of databases, and a processing request receiver determines, based on an attribute of the geographic data necessary for displaying the objective geographic information, which geographic data acquiring processor among the plurality of geographic data acquiring processors is requested to execute processing. As a result, a user can obtain required geographic data without knowledge of where the desired geographic data is or without being aware of where the knowledge is prepared.

摘要： In a digital cartographic system for processing geographic information, a map projection of a map is converted. The map projection transformation is carried out with a coordinate value in which longitude and latitude are set to a center by way of a linear interpolation so as to simplify a calculation required for transforming the map projection, and also not depending upon a map projection to be converted. Also, after the transformation process operation, a reference line such as longitude/latitude and an equiangular line is superposition-displayed/overlapping-displayed in order to assist an analysis, in response to a demand. In accordance with the present invention, a map can be shown with correctness of a distance and correctness of azimuth by performing various sorts of map-projection transformation, the digital cartographic system can support an intuitive idea of a user, and also can improve an information representation function of this digital cartographic system.

摘要： The present invention offers a feature data management method which provides data indicating created time and destroyed time of geographic object for feature data, thereby increasing the speed and facilitating a search in time direction. By this method, for example, if the building C is built at time Ts and destroyed at time Te, created time Ts and destroyed time Te of geographic object C are registered in the feature data, whereby it can be managed by a database that the geographic object C existed only between times Ts and Te.

摘要： In the case where a map is used as a figure upon vertical scrolling for enlarging or reducing a map having a predetermined accuracy, a map having a higher accuracy as well as a map having a less amount of graphic data are subjected to vertical scrolling so that the map having a lower accuracy or the less amount of data is displayed superposing on the map having the higher accuracy. Upon vertical scrolling, the speed of vertical scrolling is improved in such a manner that the brightness of one of the maps which is gradually reduced is decreased to an extent in which a positional relation of the one map with the other map which is gradually enlarged is not unrecognizable to an operator and the one map displayed with a predetermined size is erased from a display device when the brightness of the one map is decreased to zero. Even in the case where the above-mentioned vertical scrolling and horizontal scrolling are used in combination, the scrolling is made with an improved speed. In the case where a three-dimensional figure is to be subjected to horizontal scrolling, a two-dimensional version of the three-dimensional figure from which information of height is eliminated is subjected to visual-point conversion and the visual-point converted two-dimensional figure is used upon horizontal scrolling, thereby improving the speed of horizontal scrolling.
摘要翻译：在垂直滚动中使用地图作为放大或缩小具有预定精度的地图的图形的情况下，将具有较高精度的地图以及具有较少图形数据量的地图进行垂直滚动，使得具有较低精度或较少数据量的地图显示为叠加在具有较高精度的地图上。在垂直滚动时，垂直滚动的速度被提高，使得逐渐减小的一个地图的亮度减小到一个地图与逐渐扩大的另一个地图的位置关系为当一个地图的亮度减少到零时，不能对操作者进行识别，并且从显示装置擦除以预定尺寸显示的一个地图。即使在组合使用上述垂直滚动和水平滚动的情况下，也以提高的速度进行滚动。在要对三维图形进行水平滚动的情况下，对从其中消除高度信息的三维图形的二维版本进行视觉点转换，水平滚动使用尺寸图，从而提高水平滚动的速度。
