Pedrl-Algorithm工程介绍
本工程在VS2017下开发，用C#在.net core 2.1上实现。
这是一个RESTFUL风格的WebApi工程。
接口文件在"./Code/Pderl/Controllers/DemController.cs "处编写。
主要功能函数在"./Code/Pderl/DemAnalysisHandle.cs"处编写。
这是一个算法测试工程，测试用的DEM数据并不是连续的，按文件放在"./DEM/"。读者也可自行添加DEM文件（只支持*.tif格式）。
如有需要可以联系我(blct_w@foxmail.com)。
按如下步骤进行代码测试:
- 拷贝proj.dll到您电脑的执行文件夹，Windows系统为“C:\Windows\System32”，您也可以使用自己编译的OSGeo/PROJ；
- 还原工程；
- 启动运行；
- 决定好您要在哪块DEM文件上进行测试，比如"ASTGTM2_N41E119_dem.tif"文件，请在浏览器地址栏输入".../api/dem/setdem/ASTGTM2_N41E119_dem"并回车；
- 在浏览器中输入RESTFUL风格的API资源地址访问服务，比如说".../api/dem/analysis/119.5/41.5/119.55/42.55/2"，然后回车，您将得到PDERL以N119.5°，E41.5°，距离地面2米为观测点，至边缘点N119.55°，E41.55°的方形区域分析结果。值得注意的是，您输入的经纬度范围不可超过上一步中DEM文件的覆盖范围。
- 更多的测试API请查看"./Code/Pderl/Controllers/DemController.cs "文件的路由定义部分。
Pedrl-Algorithm
This project is code in vs2017 with C# under .net core 2.1.
This a restful WebApi project.
The api service is code in the "./Code/Pderl/Controllers/DemController.cs ";
The main function of Pderl is code in "./Code/Pderl/DemAnalysisHandle.cs";
The DEM used in this project is not continuous. All dems available are in folder "./DEM/", and you can add your own dem file to this folder (only support *.tif);
Email:blct_w@foxmail.com
To test following these steps :
- Copy proj.dll to your computer's execution folder, such as the "C:\Windows\System32" folder for Windows. You also can use your own compiled OSGeo/PROJ;
- Restore this project;
- Run;
- Decide which DEM file do you want to test on, for example "ASTGTM2_N41E119_dem.tif", then input ".../api/dem/setdem/ASTGTM2_N41E119_dem" in your browser and press the enter key;
- To test the Pderl, input the restfull api url in your browser, for example ".../api/dem/analysis/119.5/41.5/119.55/42.55/2" then press enter. You will get the results of PDERL square area analysis with 119.5° N, 41.5° E, 2m above the ground as the observation point, N119.55°,E41.55° to the edge point. Note that the latitude and longitude range of the test must not exceed the coverage of the DEM file you set up in the previous step.
- For more test api, please see the routing definition part of the function in "./Code/Pderl/Controllers/DemController.cs ";
