QuickEarth(以下简称QE)是一个二三维一体化的Web端矢量和栅格数据渲染引擎,适用于气象、海洋、水文、环境等领域的数据可视化。目前二维版本面向个人免费开放。如需要商用或者需要三维版本,可以与我们联系购买。

注意:当前二维版本已经完全免费,不需要证书即可部署使用,三维需要证书才能部署到生产环境,但是可以在本地免费学习测试,也可以联系我们获取三维免费试用版本证书。

开始之前

QE引擎本身的使用需要具备一定的前端代码开发能力,如果还不具备,建议先学习一些基础的前端开发知识。

点击查看更新日志

快速开始

QE支持使用打包器进行模块化开发,也支持直接使用Script标签引入进行开发。

使用Webpack+Typescript开发

# 将代码克隆到本地,也可以在页面直接下载zip包
git clone https://gitee.com/mofangbao/quick-earth-free
# 安装依赖(建议先设置npm为国内镜像: npm config set registry http://registry.npm.taobao.org
npm install
# 启动开发调试
npm start
# 打包发布版本
npm run build

详细教程可以点此查看文档

使用srcipt标签和原生JS开发

本脚手架的umd目录中的js文件是用来在umd模式下开发的,具体可以查看同目录中的index.html,也可以点此查看详细教程

前端工具支持

当前测试支持的有webpack和vite,理论上只要Leaflet和Cesium支持的工具均可以使用。

我们建议使用Typescript +React/Vue进行开发。

关于在线平台

学习一个新的框架最好的莫过于上手体验了,因此我们特别开发了这个在线体验的平台,这里有非常多的DEMO可以用来学习参考。

常见问题

底层使用了开源库吗

是的。

  • 二维上QE使用了Leaflet作为底层GIS框架。

  • 三维上使用了Cesium

我们自研的部分是数据渲染的图层,底层是基于现有轮子的,方便复用社区已有的大量组件。

什么格式的数据才能被QE渲染

QE的数据解析和渲染是分开的,因此本身没有限定数据格式,只是限定了数据结构。

对于矢量数据,只要能转换为GeoJSON形式,即可被渲染。

对于栅格数据,QE本质上定义的是一个一维数组和格点的开始、结束、间隔信息。任意格式的栅格数据只要通过自己编写解析器转换为这个数据结构都可以被渲染。

GNU LESSER GENERAL PUBLIC LICENSE Version 3, 29 June 2007 Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/> Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed. This version of the GNU Lesser General Public License incorporates the terms and conditions of version 3 of the GNU General Public License, supplemented by the additional permissions listed below. 0. Additional Definitions. As used herein, "this License" refers to version 3 of the GNU Lesser General Public License, and the "GNU GPL" refers to version 3 of the GNU General Public License. "The Library" refers to a covered work governed by this License, other than an Application or a Combined Work as defined below. An "Application" is any work that makes use of an interface provided by the Library, but which is not otherwise based on the Library. Defining a subclass of a class defined by the Library is deemed a mode of using an interface provided by the Library. A "Combined Work" is a work produced by combining or linking an Application with the Library. The particular version of the Library with which the Combined Work was made is also called the "Linked Version". The "Minimal Corresponding Source" for a Combined Work means the Corresponding Source for the Combined Work, excluding any source code for portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The "Corresponding Application Code" for a Combined Work means the object code and/or source code for the Application, including any data and utility programs needed for reproducing the Combined Work from the Application, but excluding the System Libraries of the Combined Work. 1. Exception to Section 3 of the GNU GPL. You may convey a covered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL. 2. Conveying Modified Versions. If you modify a copy of the Library, and, in your modifications, a facility refers to a function or data to be supplied by an Application that uses the facility (other than as an argument passed when the facility is invoked), then you may convey a copy of the modified version: a) under this License, provided that you make a good faith effort to ensure that, in the event an Application does not supply the function or data, the facility still operates, and performs whatever part of its purpose remains meaningful, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy. 3. Object Code Incorporating Material from Library Header Files. The object code form of an Application may incorporate material from a header file that is part of the Library. You may convey such object code under terms of your choice, provided that, if the incorporated material is not limited to numerical parameters, data structure layouts and accessors, or small macros, inline functions and templates (ten or fewer lines in length), you do both of the following: a) Give prominent notice with each copy of the object code that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document. 4. Combined Works. You may convey a Combined Work under terms of your choice that, taken together, effectively do not restrict modification of the portions of the Library contained in the Combined Work and reverse engineering for debugging such modifications, if you also do each of the following: a) Give prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are covered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that displays copyright notices during execution, include the copyright notice for the Library among these notices, as well as a reference directing the user to the copies of the GNU GPL and this license document. d) Do one of the following: 0) Convey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a form suitable for, and under terms that permit, the user to recombine or relink the Application with a modified version of the Linked Version to produce a modified Combined Work, in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source. 1) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer system, and (b) will operate properly with a modified version of the Library that is interface-compatible with the Linked Version. e) Provide Installation Information, but only if you would otherwise be required to provide such information under section 6 of the GNU GPL, and only to the extent that such information is necessary to install and execute a modified version of the Combined Work produced by recombining or relinking the Application with a modified version of the Linked Version. (If you use option 4d0, the Installation Information must accompany the Minimal Corresponding Source and Corresponding Application Code. If you use option 4d1, you must provide the Installation Information in the manner specified by section 6 of the GNU GPL for conveying Corresponding Source.) 5. Combined Libraries. You may place library facilities that are a work based on the Library side by side in a single library together with other library facilities that are not Applications and are not covered by this License, and convey such a combined library under terms of your choice, if you do both of the following: a) Accompany the combined library with a copy of the same work based on the Library, uncombined with any other library facilities, conveyed under the terms of this License. b) Give prominent notice with the combined library that part of it is a work based on the Library, and explaining where to find the accompanying uncombined form of the same work. 6. Revised Versions of the GNU Lesser General Public License. The Free Software Foundation may publish revised and/or new versions of the GNU Lesser General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns. Each version is given a distinguishing version number. If the Library as you received it specifies that a certain numbered version of the GNU Lesser General Public License "or any later version" applies to it, you have the option of following the terms and conditions either of that published version or of any later version published by the Free Software Foundation. If the Library as you received it does not specify a version number of the GNU Lesser General Public License, you may choose any version of the GNU Lesser General Public License ever published by the Free Software Foundation. If the Library as you received it specifies that a proxy can decide whether future versions of the GNU Lesser General Public License shall apply, that proxy's public statement of acceptance of any version is permanent authorization for you to choose that version for the Library.
