In the prior art, if a user changes a support GIS platform, even if the functional requirements of the user do not change, a code frame needs to be changed, and codes are rewritten to adapt to the corresponding GIS platform. For GIS projects, the idea of users for GIS application interface styles is constantly changing, and needs to be continuously developed and written with codes to modify the overall layout and style to meet the requirements of users.
Therefore, a uniform map service interface is provided in the application, and the map service interface can be conveniently adapted to the mainstream GIS platforms (ArcGIS, superMap and OpenLayers) on the market. And provide abundant basic GIS function library, satisfy simple business scene, secondly provide the function and construct the engine, can assemble a plurality of basic GIS functions through visual interface thereby to construct new function, can satisfy complicated business scene betterly.
Referring to fig. 1, an embodiment of the present application provides a method for generating a geographic information system GIS application, including the following steps:
s101: configuring parameters of a plurality of map services in a visual interface, and analyzing the parameters of the plurality of map services through a unified map interface so as to read map data of the plurality of map services;
it should be noted that the parameters of the plurality of map services may be information such as a map service address, a map service providing platform, and a map service type. The unified map service interface can be well adapted to GIS platforms in the market, such as ArcGIS, superMap, openLayers and the like.
In some implementations, parsing can also be performed according to parameters of multiple map services to read sub-hierarchy information, and the sub-hierarchy information is automatically populated into a database form. The sub-hierarchy information may include one or more sub-hierarchies, for example, in a map service, where the map service is similar to a folder and the sub-hierarchies inside the map service are similar to files in the folder.
GIS platforms on the market are various, each platform has a map service type corresponding to the GIS platform, and firstly, the access logic of each map type is written in a core code; secondly, judging the map is accessed in which way through the map service type configured by the user and a map provider; and finally, matching different map service types into different map type implementation methods to realize the analysis of different map services. It should be noted that the service type may be, for example, a component service, a dynamic service, or the like, and the map provider may be, for example, arcgis, supermap, or the like. For example, if the map service configured by the user is mapserver service provided by an arcgis platform, the system matches a corresponding map access method according to the configured parameter, and the map access method is provided by the respective GIS platform.
Specifically, a map service is added in a visual interface, information such as a map service address, a map service providing platform (arcgis, supermap, geoScene, internet and the like), a map service type (grid slice, dynamic service, element service, vector slice and the like) and the like is configured into a generating device of the GIS application, and the generating device of the GIS application can judge corresponding parameters required by various map services according to a unified map interface, so that automatic filling and reading of sub-hierarchy information of the map service are realized, and all configurations are stored in a database form. In particular, the corresponding parameters may be a map service provider and a map service type.
S102: configuring parameters of a plurality of functional components in a visual interface, storing the parameters of the functional components in a database form, and constructing a new functional component on the visual interface according to the functional components;
it should be noted that when a part of the functional components are operated in the application, the map service data may be needed, for example, the function of querying the project needs the map service data of the project to query the project. However, in some implementations of the present application, configuration data for a plurality of functional components may not be generated from map data for a plurality of map services. For example, survey ranging, which functions without the need for map data for map services.
The configuration of the functional components may also be obtained without the configuration map service data, and generally includes: component name, component path, extended configuration, etc. When the functional component runs in the application, the function which is realized in the system is found through the component path in the parameter, that is, the function can be run, and if the functional component needs a certain map service, the function can be configured in the extended configuration.
The explanation for the function building engine is as follows:
firstly, a basic function library (for example, the basic function library includes functions of map service inquiry, graph drawing and the like) is provided, the basic function library can meet the basic application scene, a part of basic functions can be configured in advance in the basic function library, the functions are already implemented in codes, and the following parameters are configured to be directly used.
Specifically, the complex function may be further constructed by the basic function in the component basic function library, which may include the following steps:
1. a base function is selected from a base function library.
2. Selecting map service data required by the function, and configuring input and output of each function.
Wherein the input and output of each function is to connect each basic function.
It should be noted that, in some implementation manners of the present application, the map service data may not be adopted, and the implementation of the embodiment of the present application is not affected.
Taking the number of cells in a certain drawn area as an example:
1. selecting a basic function-drawing surface;
2. configuring parameters of the drawing surface: map data, input data: none, output data: a drawn graph;
3. selecting a basic function-query map service;
4. configuring parameters of a map query service, and inputting data: the output parameters of the plot service plus the previous function drawing surface are as follows: and drawing cell data in the range.
Selecting a certain functional component in the basic GIS functional library, setting input and output parameters of the functional component, selecting map data required by the functional component from the map service configured in S101, completing the configuration of the first function, and further configuring other required basic GIS functions according to the step. The logic flow order of each basic GIS function may also be adjusted after the configuration of the functional components and all configuration data is saved in the database table.
It should be noted that the generated multiple functional components may be added to the basic GIS functional library for later reuse.
For example, a peripheral analysis function is required, which is used to analyze how many cells are around a supermarket, and the peripheral analysis function can be configured with a buffer area generation function to obtain a range area of 1km around the supermarket, and then a space query function can be configured to perform space query through the obtained range area and a cell point diagram layer to query out cells within the range.
For example, two attribute query functions need to be configured, and first, the attribute query function can be configured to query a lake layer to query a lake with a first name; and secondly, an attribute query function can be configured, the lake layer is queried by taking the lake to be queried as a query condition, and the constructed new function can be normally used if the query result is the same lake named as the first lake.
A function construction engine is provided, a plurality of basic GIS functions can be assembled through a visual interface, so that a new function is constructed, and a complex service scene is met.
S103: configuring an interface style on a visual interface according to a plurality of functional components;
specifically, a plurality of basic interface rule models can be built in the GIS application generation device for selection, and if the theme color of the basic interface rule models does not meet the requirements, the theme color band can be modified.
Further, an interface rule model can be newly established. For example, an interface rule model is newly established in the visual interface, wherein interface components such as a drag text, a radio box, a check box and the like can be used, corresponding parameters of each interface component are configured, a function component corresponding to the interface component is selected from a basic GIS function library configured in S102, the function corresponds to an interface style, all configuration data are stored in a database form after the function is completed, and the newly established interface rule model is added to the basic interface rule model for later reuse. It should be noted that the corresponding parameter of the interface component may be a placement position parameter, a width height parameter, a border color parameter, and the like.
The visual configuration interface providing the customizable interface style rule can quickly respond to the personalized requirements of the user on the interface style.
S104: generating a GIS application according to the map data, the plurality of functional components and the interface style of the plurality of map services.
The method specifically comprises the following steps:
the method comprises the following steps: acquiring an application code, an application name, an initial map range and a coordinate system of a first GIS application to be configured;
step two: selecting a functional component of a first GIS application to be configured according to a database list;
step three: selecting an interface style of a first GIS application to be configured according to the newly-built interface rule model;
step four: and generating a first GIS application according to the functional component of the first GIS application to be configured and the interface style of the first GIS application to be configured.
The method for generating the GIS application can adopt an application building algorithm to respectively build the functional components, the interface components and the interface styles into corresponding models so as to directly carry out visual configuration on the GIS application according to each model in the following process. Wherein each model can be understood as a visualization of each configuration parameter. Can be prepared by
For example, an application is newly built in the visual interface, information such as an application code, an application name, a map initial range, a coordinate system and the like is configured, in the functional model, a required functional component is selected from the basic GIS functional library built in S102, and in the interface model, an interface rule is selected from the interface rule model built in S103.
It should be noted that after generating the GIS application, the integrity of the GIS application configuration may be checked, wherein the integrity may include, but is not limited to, uniqueness, consistency, integrity, and connectivity. For example, for the configuration of the map service, whether necessary parameters in the map service are null or not can be judged, for example, if a service address is null, the user is reminded of the configuration problem in a red color, and if the configuration is used, the application cannot run; it may also be determined whether the map service address is accessible. For the functional component, whether the input and output parameters are null or not can be judged; for the interface model, whether the configured interface component lacks necessary parameters or not can be judged, and the wrong configuration information is listed for the judgment of the user.
The process shown in fig. 1 is to configure a plurality of map services in a visualization interface, and analyze parameters of the plurality of map services through a unified map interface, so as to read map data of the plurality of map services; configuring parameters of a plurality of functional components in a visual interface, storing the parameters of the functional components in a database form, and constructing a new functional component on the visual interface according to the functional components; configuring an interface style according to a plurality of functional components on a visual interface; generating a GIS application from the map data, the plurality of functional components, and the interface style of the plurality of map services. The configuration data is arranged in a database form, the configuration data of each component is arranged in a visual interface, and GIS application is generated according to each component, so that the GIS application is configured through the visual interface.
Referring to fig. 2, the present application further provides another method for generating GIS applications of a geographic information system, and because multiple sets of application systems need to be deployed when different GIS application systems are used in the prior art, reusability and convenience are lacking. Therefore, the embodiment of the present application may add a loading step on the basis of fig. 1, and specifically includes the following steps:
s201: loading different types of map services;
and loading a plurality of map services of the first GIS application on the visual interface according to the application code of the first GIS application. Specifically, the map service configuration information corresponding to the application code can be read from the database form according to the application code, a map service loading method which is built in the system and packaged is called, and the map service loading is realized by judging the type of the map service and calling the corresponding map service loading method. The map service configuration information may include a service address, a service provider, a service type, an authentication method, and the like.
It should be noted that different types of map service loading methods for different GIS applications are different, and each GIS application provides different jsapi for loading different map services, and the loading is implemented by writing codes.
For example, arcgis 'jsapi is used for map services, arcgis' jsapi method is used for mapserver loading, arc gisdynamicapservicelayer method is used for fatureserver loading, and FeatureLayer method is used for FeatureLayer loading. The map service of Supermap uses jsapi provided by Supermap, and the loading of the slice map uses tiledMapLayer method.
S202: loading a plurality of configured functional components;
the method specifically comprises the following steps:
the method comprises the following steps: acquiring the logic sequence of the plurality of functional components according to the function identifiers of the plurality of functional components;
step two: and loading the plurality of functional components on the visual interface according to the logic sequence of the plurality of functional components.
For example, the configuration information of the functional component corresponding to the application code may be read from the database form according to the application code. For basic GIS functions, according to the unique identification of the functional component, calling a packaged basic GIS function library built in the system, and loading corresponding function building; for the constructed new functions, acquiring function identifiers and input/output parameters of all basic functions in the new functions and logic sequences of all basic functions through function identifiers of the new functions, acquiring basic GIS functions built in a system through the function identifiers, determining operation sequences of the new functions according to the logic sequences of the basic functions, connecting all modules through the input/output parameters, wherein the output result of the last basic function is the input parameter of the next basic function, and the output parameter of the last function is the result data of the operation of the new functions.
In particular, the logical order may refer to, for example, the new function built, with three basic functions configured under the "operation" node: inquiring an item red line, creating a buffer area and performing superposition analysis, wherein when a new function is loaded, the steps are as follows from top to bottom according to the configuration sequence: query term red line-create buffer-overlay analysis. The configuration sequence may include, but is not limited to, from top to bottom, and other configuration sequences may also be adopted.
Specifically, the connection may be, for example, that the first basic function is "query item red line", a certain item range plane is queried, the range plane of a certain item is an output result of the first basic function, and then a range line of 1km around the certain item range plane can be created according to the output result of the first basic function as an input parameter of the second basic function "create buffer".
S203: and loading the configured interface style.
The method specifically comprises the following steps:
the method comprises the following steps: loading a plurality of map services of the first GIS application on a visual interface according to the application code of the first GIS application;
step two: acquiring an interface component of the first GIS application according to the newly-built interface rule model;
step three: and calling a dynamic renderer according to the interface component of the first GIS application, and rendering the interface style of the first GIS application through the dynamic renderer.
For example, the configuration information of the interface rule corresponding to the application code can be read from the database form according to the application code, the interface rule of each functional component is obtained, the corresponding interface component built in the system is called according to the type of the interface rule, and the dynamic renderer built in the browser is called according to the configuration parameters of the configured interface rule to render the interface style of the system.
It should be noted that, if the function component is a button, the button component built in the system is called, and according to the style rule of the interface rule: button border style, button background color, height width of the button, etc. The style of the function button is rendered.
For example, the buttons store the configuration information into the database form according to the background color, height width and the like of the configured buttons, when the application runs, the style configuration of the buttons stored in the database form is read, and the style of the buttons is rendered through the codes by adopting the style configuration.
It should be noted that the execution sequence of S201 to S203 may be performed sequentially or simultaneously.
