S2, after extracting unit's figure layer, carries out display configuration, creates metadata, build polymerization figure layer from spatial database.Specifically include following steps:
(1), figure layer extraction: the first figure layer needing polymerization is extracted from spatial database.
(2), display configuration: the visual effect shown according to the map, configure the ordering of each unit figure layer, in this embodiment, the most successively: POI, administrative area line, road, water system, building, administrative area cuttings, and the display visual field of each unit figure layer is set, displaying ratio chi that unit's figure layer is i.e. set interval [minViewScale, maxViewScale).This yuan of figure layer is when opening, only at the currently displaying scale curViewScale of map in the displaying ratio chi interval of this yuan of figure layer, i.e. (curViewScale>=minViewScaleandcurViewScale<maxViewScale), this yuan of figure layer could show.
(3), metadata is created: need the metadata information of record polymerization figure layer, information source as figure layer Resource TOC, the metadata of polymerization figure layer includes the contents such as figure layer title, Chinese name, date created, founder, figure layer icon, and the metadata information that polymerization is schemed layer is written to be polymerized in map data mining platform table.The metadata information of unit's figure layer includes its said polymeric figure layer ID, figure layer title, figure layer ID, layer type (point, line, surface, annotation, grid etc.), display sequence, minimum displaying ratio chi, maximum displaying ratio chi, the metadata information of unit's figure layer is as the index source of polymerization figure layer operation, write unit map data mining platform table.
Step S3, polymerization figure layer is registered in figure layer table.
Polymerization being schemed layer register in figure layer table, after registering, polymerization can be schemed layer and treats as typically scheming layer by application program, uses according to the conventional occupation mode of general figure layer.
The invention allows for the operational approach of a kind of electronic chart polymerization figure layer, owing to polymerization figure layer is not the most really set up, it is intended only as a set of each unit figure layer, is existence in logic, it is thus desirable to pass through map operation, it is achieved itself and the interactive relationship of first figure layer physically.Following several operation includes for the operational approach of polymerization figure layer:
(1), opening operation
When opening polymerization figure layer, all units figure layer that polymerization figure layer is comprised needs to open simultaneously.Therefore, when loading polymerization figure layer, need to read the metadata information of first figure layer of its correspondence from unit's map data mining platform table, including figure layer title, figure layer ID, minimum displaying ratio chi, maximum displaying ratio chi, travel through all units figure layer, call figure layer open method, open all units figure layer that polymerization figure layer comprises one by one, and its ordering is set according to the sequence of each unit figure layer.
(2), shutoff operation
When closing polymerization figure layer, all units figure layer needs that polymerization figure layer is comprised simultaneously close off.Therefore, when loading polymerization figure layer, recall first map data mining platform of preserved polymerization figure layer, travel through all units figure layer, call figure layer method for closing, close all units figure layer that polymerization figure layer comprises one by one.
(3), display operation
Owing to polymerization figure layer includes multiple units figure layer, it can be different that the display of each figure layer is arranged, therefore, for adapting to the display of current map, need to detect the visual field change events of map window, obtain the currently displaying scale curViewScale of map, recall first map data mining platform of preserved polymerization figure layer, travel through all units figure layer, only when the currently displaying scale of this map fall at unit's figure layer when displaying ratio chi interval is set, i.e. (curViewScale>=minViewScaleandcurViewScale<maxViewScale), just show the map elements of this yuan of figure layer.
(4), operation is derived
When deriving polymerization figure layer, need to derive all units figure layer that its this polymerization figure layer comprises simultaneously.Therefore, recall first map data mining platform of preserved polymerization figure layer, travel through all units figure layer, call figure layer deriving method, derive unit's figure layer one by one.
(5), synchronized update
Because map elements is the most also stored on each unit figure layer, therefore when certain map elements of certain unit's figure layer changes, such as increases, revise, delete, comprise the polymerization figure layer synchronized update of this yuan of figure layer.
Refering to shown in Fig. 3, for polymerization layer effect exemplary plot.After polymerization figure layer registration, this polymerization figure layer is treated as typically scheming layer, uses according to the conventional occupation mode of general figure layer.
(1), polymerization figure layer open is closed
Polymerization figure layer in use, in figure layer catalogue, is no longer the form of figure layer group, but as general figure layer, it appears that just as if a figure layer, can independently show use as general figure layer, carries out opening, closes, shows, hides operation.
(2), polymerization figure layer is derived
The derivation operation of polymerization figure layer, is that unification exports in each swap file by the map elements of each unit figure layer of this polymerization figure layer, corresponding one (or a set of, depending on deriving form difference) swap file of a first figure layer.Owing to each unit figure layer of polymerization figure layer is substantially that isomery, space type and attribute field can not be identical, therefore polymerization figure layer does not support import operation.
