Method and system for displaying historical spatiotemporal object information

Abstract

The present invention provides a method and system for displaying historical spatiotemporal object information. The method comprises: (a) displaying global historical spatiotemporal object time-series index data in a first graphical display window in a manner of a dynamic time-series index graph; (b) receiving a local scaling instruction and a local scaling parameter by means of a human-computer interaction interface, selecting a local time domain interval on time coordinate axis of the dynamic time-series graph, and acquiring local historical spatiotemporal object time-series index data corresponding to a range of the selected local time domain interval; and (c) performing single-dimensional enlargement or reduction transformation on the selected local time domain interval along the time coordinate axis according to the local scaling instruction and the local scaling parameter that are acquired in the step (b), and then displaying the local time-series index data acquired in the step (b) in the selected local time domain interval subjected to single-dimensional enlargement or reduction. According to the method and system for displaying the historical spatiotemporal object information provided by the present invention, the problem that organic correlation between ''global and local'' time-series index information is cut off by the display window can be well solved.

Description

technical field [0001] The invention relates to the field of computer data display, more specifically, to a method and system for displaying historical spatio-temporal object information. Background technique [0002] Historical spatio-temporal objects refer to important events that occur in various periods, therefore, historical spatio-temporal objects are also referred to as historical events in the present invention. Since historical events involve time and space information, it is very complicated to conduct a comprehensive and systematic index display of historical events. In the traditional paper-based written expression, static charts are generally constructed based on time coordinates, and the time series index of historical events is organized according to the time of occurrence and duration, and the corresponding drawings are supplemented to display event-related content or spatial information. [0003] However, as the time span increases and the number of events ...

Problems solved by technology

[0003] However, as the time span increases and the number of events increases, such a static information display method exposes flaws: due to the large time span, it has to be displayed in a static timing index map divided into multiple frames The overall historical time series index information makes it impossible for users to view the overall historical event time series index information in the same index chart, resulting in the problem of "overall and partial contradictions" in information display, that is, when people view the overall time series index information of historical events , it is difficult to view the detailed time-series index information of local historical events; and when viewing the detailed time-series index information of local historical events, it is difficult to observe its association information with other related event indexes in the overall historical process

[0005] Although the above scheme simultaneously displays the "overall and partial" time series index information of historical events, it brings new problems: the original organic connection between the overall and local time series index information of historical events is replaced by multi-window display. split apart

That is to say, when the overall and partial information of the time series index map of historical space-time objects are displayed in different graphics windows, there will be a problem that the time series index information between the part and the whole cannot be continuously displayed at the edge of the window, causing the observer In the process of viewing the time series index graph of local and overall historical space-time objects, the brain cannot obtain continuous time series index information flow input, which will affect the observer's deep grasp of the time series information of historical events
