Background technology
In existing Geographic Information System (Geographic Information System, GIS), generally each polygon object is carried out data storage or process as independently data object, as shown in Figure 1, for existing data model structural representation, under this data model, for each polygon object, all need to store the node object data corresponding with it and attribute data respectively, wherein, node object data are generally the coordinate information of each node object that polygon object comprises, such as, five node objects are comprised in certain polygon object, the node object data so stored are just the coordinate information of five node objects, (X1, Y1), (X2, Y2), (X3, Y3), (X4, Y4), (X5, Y5), attribute data is generally the name information of polygon object, descriptor etc.Under this processing mode, be separate between different polygon object, there is no inevitable contact, when editing polygon object, also be all in units of single polygon object, carry out individually-edited, as edited the node object data and attribute data etc. of each polygon object.
In prior art, when carrying out image rendering, general in units of single polygon object, play up each polygon object one by one, wherein, the mode that many employings node is played up is played up, such as, five nodes are comprised in certain polygon object, then when playing up this polygon object, first check the coordinate information of five node objects of this polygon object stored in data model, then according to the coordinate information of five node objects, play up this five node objects, then render this polygon object further according to five node objects rendered.
The situation that multiple polygon object has common node object may be there is in actual applications, that is, at least two polygon object have the identical node object of coordinate information, prior art is when playing up each polygon object with common node object, for the node object that coordinate information is identical, need repeatedly to play up, such as, polygon object 1 and polygon object 2 have the identical node object A of coordinate information, when playing up polygon object 1, need the coordinate information rendering node object A according to correspondence, when playing up polygon object 2, also the coordinate information rendering node object A again according to correspondence is needed, therefore the node object A in the polygon object 1 and node object A in polygon object 2 overlaps.
If multiple polygon object has common node object, when then dragging this common node object on certain polygon object, because this common node object is played up respectively in each polygon object, therefore can not there is position and move in this common node object on other polygon object, any change can not be there is in other polygon object, therefore the interlock had between the polygon object of common node object cannot be realized, make the efficiency of image procossing lower, especially, when processing a large amount of polygon object, this mode of operation has had a strong impact on treatment effeciency.Such as, polygon object 1 and polygon object 2 have the identical node object A of coordinate information, as shown in Figure 2 A, when dragging node object A on polygon object 1, this node object A still can keep original position on polygon object 2, therefore can not there is any change in polygon object 2, as shown in Figure 2 B.
In addition, existing data model structure is applicable to the polygon object that there is not incidence relation, when multiple polygon object has common node object, even if the coordinate information of this common node object in multiple polygon object is identical, according to existing data model structure, still in the node object data of each polygon object, the coordinate information of this common node object can be stored respectively, therefore result in data redundancy and store.
