Problems solved by technology
The current WebGIS business logic is realized through JavaScript technology. However, now that the business requirements are becoming more and more complex, the amount of front-end development code is becoming more and more, while JavaScript technology has complex code logic, large amount of code, and computational analysis. Its own defects such as weak performance, especially in the face of dynamic refresh and drawing of complex linear symbols, its calculation performance and real-time performance cannot meet business requirements, thus affecting the operating efficiency of WebGIS applications

The invention relates to an algorithm module generation method based on a WebAssembly technology and a linear symbol drawing method. The algorithm module generation method comprises: creating a C / C++algorithm class of each linear symbol, and generating a C / C++ algorithm library; packaging the input and the output of the C / C++ algorithm class by using an Embedded compilation tool to generate a wasm interface; and compiling the C / C++ algorithm library by using an Emscripten compiling tool to generate a wasm algorithm library and a js interface library. According to the method, the calculation performance of the Web front end is improved, the construction and rendering efficiency of the front end model is improved, and the requirement of a user for dynamically and quickly drawing the linearsymbol model is met.
Description
technical field [0001] The present invention relates to Web-side geographic information system (WebGIS) technology, in particular to a method for generating algorithm modules and a method for drawing linear symbols based on WebAssembly technology. Background technique [0002] With the continuous development of Internet technology and people's demand for geographic information system (GIS), it is an inevitable trend to use the Internet to display geographic information on the Web, and the application field of WebGIS technology continues to expand. The current WebGIS business logic is realized through JavaScript technology. However, now that the business requirements are becoming more and more complex, the amount of front-end development code is becoming more and more, while JavaScript technology has complex code logic, large amount of code, and computational analysis. Its own defects such as weak performance, especially in the face of dynamic refresh and drawing of complex l...
