Abstract
The invention discloses a method for achieving a mobile terminal GIS platform on an android system and an apple system. The method is applied to the field of geographical information systems, and includes the main steps of firstly, writing or extracting a JavaScript and copying the JavaScript to a mobile terminal to be locally stored; secondly, establishing a mobile terminal program frame and embedding a browser in the program frame; thirdly, making the mobile terminal browser call the local JavaScript; fourthly, conducting interface encapsulation through gesture operation. By means of the method, a mature WebGIS can be converted into a mobile terminal GIS through extremely-small modification, the purpose of transplanting WebGIS professional software to the mobile terminal can be achieved to a great extent, and the requirement for supporting the mobile GIS system needed in modern mobile office work is met.
Description
Technical field
The present invention relates to area of geographic information, particularly a kind ofly in Android system and apple system, use WebGIS to realize the method for mobile terminal GIS platform.
Background technology
Mobile terminal GIS, it is the generalized information system taking mobile Internet as supporting, taking smart mobile phone or panel computer as terminal, in conjunction with the Big Dipper, GPS or base station as positioning means, it is another new hot technology after desktop GIS, WebGIS, running fix, mobile office etc. more and more become enterprise or individual's active demand, mobile GIS is exactly wherein most crucial part, and various location-based application are emerged in an endless stream.
The generalized information system major part of our application is to adopt WebGIS system at present, and a lot of ripe GIS platform and professional application on WebGIS, owing to being new technology, GIS platform on mobile terminal is very few, and functional interface contrast desktop GIS, WebGIS is few, can only meet simple map view, place name address search, location, the public demands such as navigation, cannot load special layer, cannot meet as land departments, the demand of specialty such as Mapping departments, and mobile office more and more becomes territory, the active demand of Surveying and Mapping Industry, as the geographical national conditions generaI investigation for the first time of the recent whole nation.And there are a lot of mature professional WebGIS application to want to be transplanted in mobile terminal, but need to change bottom GIS platform, due to Floor layer Technology difference, open development interface difference, it is huge that the portability function of platform is faced with workload, also has the problem that cannot transplant owing to lacking some function of development interface.
Summary of the invention
The present invention has overcome the deficiencies in the prior art, by after the WebGIS transformation of existing maturation, is transplanted in Android system or apple system, and a kind of method that realizes mobile terminal GIS platform is provided.
The present invention realizes above-mentioned purpose by the following technical solutions:
The method that realizes mobile terminal GIS platform in Android system and apple system, the method step comprises:
Step 1, first write or extract JavaScript script and copy the local storage of mobile terminal;
Step 2, build program of mobile terminal framework and browser is embedded to program frame again;
Step 3, then browser of mobile terminal is called to local JavaScript script;
Step 4, last gesture operation interface encapsulation.
The described method that realizes mobile terminal GIS platform in Android system and apple system to better implement the present invention, described step 1 comprises the following steps:
Step 1.1, according to the development interface of WebGIS platform S, write or extract the JavaScript script of existing WebGIS professional application, JavaScript script is saved as to the file A that suffix is " .html ";
Step 1.2, file A is copied in this locality storage B of mobile terminal.
The object of this step is that the JavaScript script of WebGIS professional application is released, to be applied in step 3.
The described method that realizes mobile terminal GIS platform in Android system and apple system to better implement the present invention, described step 2 comprises the following steps:
Step 2.1, in the application development environment of mobile terminal, create an application program C;
Step 2.2, in the main interface framework of application program C, add a browser control part D;
The parameter of step 2.3, configure browser control D, cancels webpage zoom function and zoom control that browser control part D carries.
The object of this step is to create program of mobile terminal framework, and this framework comprises browser control part, and this browser control part is for the JavaScript script of load step 1.
The described method that realizes mobile terminal GIS platform in Android system and apple system to better implement the present invention, described step 3 comprises the following steps:
Step 3.1, in the main interface initialization of mobile applications C function E, add browser control part D;
Step 3.2, call the code of file A, realize the function that shows map in browser control part D.
The description of this step be the JavaScript script in load step 1 in step 2 browser.
The described method that realizes mobile terminal GIS platform in Android system and apple system to better implement the present invention, described step 4 comprises the following steps:
Action Events F is hit in step 4.1, the list indication that makes application program C monitor browser control part D, the function of event F be encapsulated as in file A, call WebGIS platform S click map API;
Step 4.2, make that application program C monitors browser control part D singly refer to double click operation event G, the function of event G is encapsulated as and calls the double-click map API that calls WebGIS platform S in file A;
Step 4.3, make that application program C monitors browser control part D singly refer to slide event H, the function of event H is encapsulated as and calls the translation map API that calls WebGIS platform S in file A;
Step 4.4, make application program C monitor two slide event I that refer to of browser control part D, the function of event I is encapsulated as and calls the convergent-divergent map API that calls WebGIS platform S in file A.
The effect of this step is to make mobile terminal GIS platform support the distinctive gesture operation of mobile terminal.
The present invention compared with prior art, has the following advantages and beneficial effect:
(1) this method is slightly transformed the WebGIS of existing maturation, is transplanted in Android system or apple system, possesses all functions of original WebGIS, and all development interfaces are constant, reduces development amount.
(2) this method need to not build the GIS platform of mobile edition from bottom, be easy to just the WebGIS that has originally done specialized function exploitation to be transplanted in panel computer or smart mobile phone, do not need to change GIS platform, evade and change the risk that the huge workload brought of GIS and some function cannot realize.
(3) utilize WebGIS can read the characteristic of browser rs cache, realize off-line browsing map by controlling Android/apple system browser rs cache.
Brief description of the drawings
Fig. 1 is the process flow diagram of the inventive method.
Embodiment
Below by embodiment, the invention will be further described, so that advantages and features of the invention are easier to be understood, but protection scope of the present invention is not limited to these embodiment.
