Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In the following description, suffixes such as "module", "part", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no peculiar meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
In the traditional map symbolization method, one is a C/S mode, and usually different geographic elements are represented by different symbols by utilizing GIS software such as ArcMap and QGIS. The other mode is a B/S mode, map symbolization is carried out by using a mode through WFS service, the map mode of the mode is fixed at a server end, interaction of a user-defined map mode cannot be realized, and maintenance is difficult.
The map service platform provides a sharable, WYSIWYG (what you see is what you get) map service for the problems of difficult symbolic sharing, poor current situation, difficult interaction, difficult maintenance and the like of a map, a user carries out symbolic editing on the map in a self-defined mode at an internet (WEB) end, and a server updates the solution of the map service according to an editing result, so that the aim of interactive map styles can be achieved, and iterative editing of the map is realized.
In a first aspect, an embodiment of the present invention provides a data processing method, as shown in fig. 1, where the data processing method includes the following steps:
in step S110, a corresponding final map style is generated according to the received formatted data carrying the style information; the style information comprises a map layer and an incidence relation between at least one map geographic element and a map symbol in the map layer, and the map style is a set formed by the incidence relation between at least one map geographic element and the map symbol in the map layer;
in step S120, the map layer and the final map style corresponding to the map layer are provided to a map service platform.
It should be noted that one map in the present invention includes at least one map layer, each map layer corresponds to one map style, each map layer includes a plurality of map geographic elements, and a symbolized map is obtained by setting corresponding map symbols for the map geographic elements.
And the user symbolizes and edits the map data in a self-defined mode at the WEB end, and sets corresponding map symbols for the map geographic elements in the map. The association relationship between each edited map geographic element and the map symbol is filled in the formatted data file as style information. After the edition is finished, the WEB end sends the data file carrying a plurality of pieces of style information to the server end.
Optionally, the formatted data described in the present invention includes, but is not limited to, one or a combination of more of the following formats: java Script Object Notation (JSON), extensible Markup Language (XML).
The formatted data in the present invention may be a message in a predetermined format, or a file in a predetermined format, or may be formatted data in other forms, and the formatted data file is used herein for convenience of description, but the formatted data in the present invention includes, but is not limited to, a formatted data file form.
And the server terminal analyzes each piece of style information from the formatted data and according to each map geographic element and each map layer in the style information. Because each map layer corresponds to one map style, the association relationship between the map geographic element and the map symbol can be updated to the corresponding map style. When all map geographic elements in each map layer of a map are provided with corresponding map symbols, the map can be displayed in a symbolized manner.
Alternatively, the map styles described in the present invention may be in, but are not limited to, the SLD file format.
It should be noted that the map layer data itself occupies a large amount of space, and if the information related to the map layer is always transmitted in the editing process, a large amount of network transmission resources are consumed, and the efficiency is low. In the invention, a user accesses the map through the WEB terminal, and the formatted data file only carries the association relation between each edited map geographic element and the map symbol and does not carry other map layer data with concrete map symbols, so that if the map geographic elements edited by the user are not large in quantity, the content of the formatted data file is small, the data quantity transmitted by the WEB terminal and the server terminal can be reduced, the network resources are saved, and the burden of a processor can be reduced. As such, even if multi-user editing or frequent editing occurs, the style information is transmitted only for the edited portion, and network congestion due to transmission of a large amount of map layer information or repeated processing of map layer data by the processor for a long period of time is not caused.
It should be noted that, for a map, the map style may not be generated after all the map geographic elements on all the map layers are set with the map symbols, or the map style may not be generated after all the map geographic elements on all the map layers are set with the map symbols, and the map style may not be issued to the map service platform. The user can only edit a part of map geographic elements in the map layer each time, the style information generated each time is overlapped and updated to the map style corresponding to the map layer, the map style of the map layer is gradually perfected through repeated iteration, and finally map symbolization is realized.
In the process of displaying the map, according to the requirement of a user on the map service, one map can only display part of map layers, and symbols corresponding to geographical elements of the part of the map can also be displayed in one map layer according to the requirement. The user can further edit the map displayed on the WEB side in a WYSIWYG mode, set the incidence relation between the map geographic elements and the map symbols, send the newly edited style information to the server side, the server side updates the map style in an iteration mode according to the newly received style information and sends the updated map style to the map service platform, so that the rapid iteration of map symbolization is realized, and the situation is improved.
As an alternative embodiment, as shown in fig. 2, step S110 may be specifically decomposed into the following steps:
in step S111, the formatted data carrying the style information is parsed, acquiring the style information;
in step S112, the final map pattern corresponding to the map layer is generated according to the map layer included in the pattern information and the association relationship between the map geographic element and the map symbol.
And after receiving the formatted data file of the WEB side, the server side analyzes the data file and extracts the style information in the data file. Since a user may edit multiple map layers in a map at the same time, multiple map geographic elements in multiple map layers may be included in a data file. In order to improve the processing efficiency, map geographic elements belonging to the same map layer in the formatted data file are put together for processing, and the incidence relation between the map geographic elements and the map symbols is superposed and updated into the map style of the map layer. And then processing the map geographic elements belonging to the other map layer.
The map geographic elements belonging to the same map layer can be processed in batch, so that the processing efficiency is improved; secondly, only individual map geographic elements in the map layer can be processed, so that the map style can be updated in a light weight manner, and the requirement of quick iteration is met; thirdly, only the map layers related to the map geographic elements contained in the formatted data file can be processed, and all the map layers in one map do not need to be loaded each time. The burden of the processor is reduced.
The map style of the present invention is editable and iterative, and for convenience of distinction, the map style generated before each editing is referred to as an initial map style, and the map style obtained after the editing is referred to as a final map style. The final map style obtained after the current editing is the initial map style for the next editing.
As an alternative, as shown in fig. 3, step S110 further includes:
in step S130, determining whether an initial map style corresponding to the map layer in the style information already exists;
in step S131, if there is no initial map style, generating the final map style according to the association relationship between the map geographic elements and the map symbols in the style information;
in step S132, if an initial map style exists, the final map style is obtained according to the initial map style and the association relationship between the map geographic elements and the map symbols in the style information.
It should be noted that, in the embodiment of the present invention, in an initial state, the map layer sent by the server to the map service platform may be a map symbol that has not yet been set for the map geographic elements, and therefore, a corresponding map style does not exist. Even if the map layer is not subjected to any symbolization processing, the map service platform can still provide map service according to the basic map layer. And editing on the map layer by the user according to the requirement. The server side generates a map style according to style information edited by a user, and a map style file needs to be newly established because the map layer does not have a corresponding map style before. In the subsequent iterative editing, the content edited each time is updated to the pattern file, and the final map pattern edited each time is obtained.
Further, for any map geographic element and map symbol in any map layer having an association relationship, generating a corresponding final map style according to the received formatted data carrying style information includes:
in the current map layer, according to a current map geographic element and a current map symbol which have an association relationship, setting map geographic elements which are in the same class as the current map geographic element in the current map layer and are all in the association relationship with the current map symbol, wherein the same class refers to the same attribute as the current map geographic element.
Many map geographic elements are included in each map layer, and there may be a large number of map geographic elements with the same attributes, for example: the trees, stations, etc. in the map have the same geographical attributes, although the locations are different. If each map geographic element is manually set by a user one by one with its corresponding map symbol, a great deal of time and effort is spent. In order to simplify the editing of the map geographic elements, only one map geographic element in the same type of map geographic elements can be edited, and the map geographic elements with the same type of map geographic elements are all effective. For example, a large number of map geographic elements identical to the map geographic elements exist in the map layer, and after the corresponding map symbols are set for the map geographic elements, the setting can be selected to be applied to the map layer. When the server side processes the style information, the incidence relation between the map geographic elements and the map symbols can be applied to all map geographic elements which are the same as the map geographic elements under the map layer. Therefore, when one map geographic element is edited, one type of map geographic element is edited, so that a plurality of repeated editing works can be saved, and the editing efficiency is greatly improved.
In a second aspect, an embodiment of the present invention provides a data processing method, as shown in fig. 4, where the data processing method includes the following steps:
in step S210, an association relationship between a map geographic element and a map symbol is set on a map layer, and style information is generated; the style information comprises a map layer and an incidence relation between at least one map geographic element in the map layer and a map symbol;
in step S220, the formatted data carrying the style information is sent to a server.
As described above, the server issues the map layer and the map style corresponding to the map layer to the map service platform, and the map service platform provides symbolic map display. The user can obtain the map information in a seeing-and-seeing manner at a WEB end, directly edits the map layer on the displayed map, sets a corresponding map symbol for the map geographic element, and generates style information according to the incidence relation between the map geographic element and the map symbol. Then, the style information is transmitted to the server in the form of formatted data.
Further, the map symbol includes a customized map symbol, and the setting of the association relationship between the map geographic element and the map symbol includes:
and setting the self-defined map symbol, and establishing the incidence relation between the map geographic elements and the self-defined map symbol.
In the process of editing the association relationship between the map geographic elements and the map symbols, if the optional map symbols provided by the map service are insufficient, the user may select map symbols with inaccurate ideograms, and the map effect displayed finally is influenced. If the waiting map service provider adds the relevant map symbols for a plurality of users one by one, the waiting process is a long waiting process, and the progress of the quick iterative editing is influenced.
In the embodiment of the invention, besides the alternative symbols provided by the map service, the map symbol can be customized by the user according to the actual needs, such as color, shape, size and other attributes of the map symbol, and the user-defined picture can be uploaded to be made into the map symbol, so that the incidence relation is established between the map symbol and the map geographic elements. Therefore, even if a proper map symbol cannot be found, the map service provider does not need to wait for creating a new map symbol, and the problem of inaccurate ideology caused by insufficient alternative map symbols is avoided. Because the pictures of the map symbols are uploaded, even if other users open the map, the map symbols can be seen, the flexibility of map symbol definition is enhanced, good sharing performance is provided, and rapid iterative editing of map symbolization is facilitated.
In a third aspect, an embodiment of the present invention provides a method for providing a map service, where as shown in fig. 5, the method includes the following steps:
in step S310, in response to an access request, determining a map to be accessed and a map layer to be accessed in the map to be accessed;

And the server side sends the map layer and the final map style corresponding to the map layer to a map service platform, and the map service platform starts map service software or provides map service in a web service mode such as weblogic, tomcat and the like.
It should be noted that, in the present invention, the server side issues the map layer and the final map style corresponding to the map layer to a map service platform, and the map service platform receives the map layer and the map style, which is only a specific implementation manner. The specific delivery mode may be various, is not limited to be published through a network, and may also deliver the map layer and the map style to the map service platform through other modes, for example: the copy is performed by a Bus system such as Universal Serial Bus (USB) and Type C Universal Serial Bus (Type-C). As an optional implementation manner, the map service platform may also be directly integrated on a server, and actual transmission is not required, and only the map layer and the map style file need to be shared for use.
