The client and the server in the technical scheme are explained, and the function of the GMap.NET is realized based on the client, so that the function of the GMap.NET can be realized on the client in the invention, namely, the corresponding control in the GMap.NET is inherited. The service end comprises the GeoServer, and all functions of the GeoServer can be realized on the service end. It can be understood that the client described in the present invention is not limited to a wide client in the prior art, and the client capable of implementing the gmap.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for providing spatial data according to the present invention. As shown in fig. 1, a method for providing spatial data according to an embodiment of the present invention includes the following steps:
s100, the client side obtains layer space data issued by the server side, analyzes the layer space data, and sends a request response stream instruction to the server side according to the layer space data.
The step S100 comprises:
and the client receives a user instruction and displays a basic map interface on the client.
NET, when the user opens the related website, the basic map interface is displayed on the client.
Firstly, map data are prestored in a server, and the server calculates and distributes map layers on the map data to form layer space data.
Net, in particular, the map data is developed by using gmap, which means that a basic map interface can be formed on a client terminal by development.
NET is known to be a powerful, free, cross-platform, open-source NET control that can pass through Google, Yahoo!in Windows Forms and WPF environments! The functions of searching for a path, geocoding and map display are realized by Bing, OpenStreetMap, ArcGIS, Pergo, SigPac and the like, and caching and running in a Mobile environment are supported. Net is a map control under Net, which can load maps of various companies based on Http protocol, such as Google, Bing, ArcGIS, the main principle is to obtain corresponding sliced maps (Tiled maps) by parsing URLs of map services of various companies and inputting corresponding parameters.
Net, it is prior art to develop a basic map interface using gmap, and will not be described herein. In the invention, a heaven and earth map CGCS2000 (a heaven and earth map is developed by using GMap. Net in the prior art) and an existing WGS84 coordinate system (a WGS84 coordinate system is used to enable the use deviation of spatial data to be small and reduce position errors caused by deviation rectification) are directly applied to the basic map interface of the invention, so that basic geographic map pictures can be formed.
NET, the server calculates and issues map layers to form map layer space data, which is also equivalent to issuing and calculating the space data by using GeoServer, and the specific operations are as follows:
it is known that GeoServer is used for an open source Service for sharing geospatial data, is an open source code server, and is implemented by J2EE in OGC Web server specification, and is implemented by multiple OGC standard services such as Web element Service (WFS, Web FeatureService), Web Map Service (WMS, Web Map Service), and Web overlay Service (WCS, Web CoverageService). The GeoServer can be used for conveniently releasing map data, allowing users to update, delete and insert the feature data, and quickly sharing spatial geographic information among the users easily.
When the GeoServer is used for issuing and calculating the spatial data, the following operations are executed:
(1) and installing GeoServer service, accessing a network administrator interface of the GeoServer, logging in by using a user name and a password, and entering the system.
(2) And copying a space data folder of a basic map interface developed by using GMap.Net to a data directory of a datadir of a GeoServer installation directory, and installing a corresponding service extension for the GeoServer.
(3) Adding a working area (the working area is equivalent to an organization directory, and can organize a plurality of data stores and layers), and naming the working area with the name of 'region'.
(4) And adding the data storage, namely adding the data storage under the region working area and naming the data storage as 'region data'. Each data storage uses a URL to locate a specific type of data source, WMS supports vector, raster and even mixed data sources, and the data storage can be published into a layer after being set. The data storage setting data source can only access the default data directory set during installation of the GeoServer. In a Windows system, the GeoServer default DATA directory may be changed by modifying the value of the system environment variable GEOSERVER _ DATA _ DIR.
(5) After the data storage is successfully set, the data storage is released as a layer, and a developer sets a layer name "provide _ region" in a data setting page, which is defined as srs; and the EPSG4326 calculates a data frame, sets the data storage through a developer, stores the set information and issues the set information as a layer.
(6) And the layer issuing verification. And entering a layer management interface, clicking a layer browsing function, inquiring the issued layer in the list, and if the data on the layer can be browsed, indicating that the layer is successfully issued. Specifically, the published spatial data is previewed by using a data preview interface provided by OpenLayers, and icons of more selectable items are clicked at the upper left corner, so that more map parameters can be changed for browsing.
The step S100 specifically includes the following steps:
and S110, the client acquires the layer space data issued by the GeoServer according to the WMS interface or the WFS interface, and analyzes the layer space data acquired from the WMS interface or the WFS interface.
The client acquires the layer space data issued by the GeoServer, and specifically means that: and the client acquires the layer space data issued by the GeoServer according to the rest interface (the GeoServer provides all rest services by using the Restlet). As is known, the rest interface includes a WMS interface and a WFS interface.
The interface for acquiring the WMS is as follows: http:// ip: port/geoserver// { working area } wms? The "image/png & trans unit" value of "true & stationary & simple & layer" { operating area: layer name } & SRS { (defined SRS } & WIDTH } & HEIGHT } & BBOX { (lower left X coordinate }, { lower left Y coordinate }, { upper right X coordinate }, and { upper right Y coordinate }.
The interface to get the WFS is: http:// { ip }: port }/geoserver/{ working area }/ows? service & version & 1.0.0& request & GetFeature & typeName & { work area }: layer name } & maxfetables & { maximum number of layer elements returned } & outputFormat ═ { result output format } & cql _ filter } & { filter field } & { filter keyword }'.
When analyzing, the client analyzes the layer space data acquired from the WMS interface, and the sending request parameters of the rest interface of the WMS correspond to: { working area }: a region; { working area: layer name }: region: service _ region; { defined SRS }: EPSG 4326; { display width }: the client displays the width of the map area; { display height }, height of the client display map area; { lower left X coordinate }: left value of ViewArea of control; { lower left Y-coordinate }: the Bottom value of the ViewArea of the control; { upper right X coordinate }: right value of ViewArea of control; { upper right Y coordinate }: top value of ViewArea of control.
The client analyzes the layer space data acquired from the WFS interface, and the parameters of the sending request of the rest interface of the WFS respectively correspond to: { working area }: a region; { working area: layer name }: region: service _ region; { maximum number of layer elements returned }: 50; { result output format }: application/json (we choose GeoJson format, but can choose other formats such as xml); { filter field }: ID; { filter key }: guangdong.
And S120, the client sends a request response stream instruction to the server according to the layer space data.
S200, the server receives the request response stream instruction, forms a response stream corresponding to the layer space data, and sends the response stream to a client.
And S300, the client generates map elements on a basic map interface displayed in advance by the client according to the response stream.
In the present embodiment, when the WMS interface is used, the step S310 is performed after the parsing is completed.
The method comprises the steps that a client sends a request for reading data to a server, the server receives the request, after a response stream is formed, step S310 is executed, the client receives the corresponding response stream through a WMS interface, and the response stream is drawn into a map picture according to an Image library preset in the server on a basic map interface displayed in advance by the client.
Specifically, after data analysis is completed, the client sends a data reading request to the server; the server packages request data into a request by creating the request object, creates a response object, and calls a service () method of the Servlet to transfer the request object and the response object; the client reads the response flow of response from the server, and draws the response flow into a map picture on the basic map interface according to an Image library (formed when data storage is set in the GeoServer and used for storing icons) provided by the server.
response is a parameter of servlet service method, and the type is javax. When the client sends out each request, the server creates a response object and transmits the response object to the servlet service () method. The response object is used for responding to the client, which shows that the response work for the client can be completed by using the response object in the service () method. The response is a response object, and a response flow in which the response body can use the response is output to the client.
Further, the client receives a transparency setting instruction, and the transparency of the map picture is changed according to a preset value. When a developer sets the transparency value of the map picture at the background, the transparency of the map picture displayed on the client changes according to a preset value.
In a preferred embodiment of the present invention, the step S310 includes:
and S311, when the client receives a map element adding instruction, setting the position of the map picture through a GMapMark control preset in the client to form a map and display the map.
Specifically, a developer classifies and encapsulates the map picture by using a GMapMark control (the GMapMark control is one of gmap. net), coordinates of the map picture on a basic map interface are defined by a GMapMark code (namely, a map element adding instruction), the width and the height of the map picture are set so that a client displays the width and the height of a map area, and the map picture is added into a point set of a self-defined default layer in the control, namely, a specific geographic position is marked (the icon is marked) on the map. And forming and displaying a complete map on a basic map interface displayed on the client.
It is known that a network map service (WMS) makes a map using data having geospatial location information. Where a map is defined as a visual representation of geographic data. The corresponding map (including grid forms such as PNG, GIF and JPEG, or vector forms such as SVG and WEB CGM) can be returned according to the request of the user. WMS supports the network protocol HTTP, and the supported operations are defined by URLs.
Overlay (layer) can be added on the Map control, multiple layers can be added, and the layer added first is displayed below. GMapMarker can be added on the map layer, and the function usually required in the use of the map is to add a self-defined icon, click the icon, delete the icon, drag the icon, highlight the icon and the like.
After the step S311, the method further includes: and S312, the client receives a map updating instruction, the map is changed, and the client analyzes the layer space data again to generate and display a new map.
Specifically, when the developer operates on the server to drag or zoom the map, so that the map displayed by the client is changed, the client resends the WMS data analysis request, repeats the above steps S310 and S311, reforms the map picture, and replaces the original map picture.
In another embodiment of the present invention, when the WFS interface is used, step S320 is performed after the parsing is completed.
The client sends a request for reading data to the server, the server receives the request to form a response stream, then step S320 is executed, the client receives the corresponding response stream through the WFS interface, the response stream is converted into a custom layer element, and the layer element is added on a basic map interface displayed in advance by the client to form a layer map.
As is known, a web element service (WFS) is a data sharing and data manipulation based on the level of geographic elements (referred to as map elements in the present invention), and supports users to insert, update, delete, retrieve, and discover services for geographic elements through HTTP in a distributed environment. The service returns GML (geographic Markup Language) data at the element level according to the HTTP client request.
Specifically, after data analysis is completed, a client reads a response stream from a server, converts the response stream into a character string according to a UTF-8 format, formats the character string Json, converts a formatted Json result into a custom layer element, and after conversion of the custom layer element is completed, a developer can perform operation at a server to set the layer element, so that the layer element is added on the basic map interface, and a layer map (one of map display modes) is formed on the client.
According to the WMS interface and the WFS interface, the data acquisition modes of the WMS interface and the WFS interface are different, and a basic map interface can be acquired according to two different ways, wherein the basic map interface is developed by GMap.
In a preferred embodiment of the present invention, the step S320 includes:
and S321, when the client receives a map element adding instruction, adding a polygon on the map layer map through a GMap polygon control preset in the client to form and display the map.
Specifically, the client inherits gmap polygon (which is one of gmap. net) of the control to realize polygon, and the obtained spatial data of the layer elements form a polygon set. And adding the polygon into the polygon set of the self-defined default layer in the control by traversing the polygons in the polygon set.
The above steps are adding polygons (gmapppolygon) on the map layer map, the map layer map is obtained through map layer elements, the polygons are drawn on the map layer map through coding (namely, map element adding instructions), the polygons being drawn can be updated through recording the position of each click on the map, the polygons being drawn are saved in gmapporay storing the polygons through updating the point sets of the polygons (namely, updating the shapes of the polygons), a map is formed, and the outline colors of the polygons are changed in the onpolygon enter and the onpolygon.
After step S321, the method further includes: and the client receives a map updating instruction, the map is changed, and the client analyzes the layer space data again to generate and display a new map.
Specifically, when the developer operates on the server, drags or zooms the map, so that the map displayed by the client is changed, the client resends the request for analyzing the WFS data, repeats the above steps S320 and S321, and redraws the polygon on the basic map interface.
The present invention further provides a system for providing spatial data, as shown in fig. 2, wherein the system includes a client and a server;
the client is used for acquiring layer space data issued by a server, analyzing the layer space data and sending a request response stream instruction to the server according to the layer space data; the client is used for receiving a user instruction, forming a basic map interface according to the response stream, and adding map elements on the basic map interface to form a map and display the map when the client receives a map element adding instruction;
