I have a json file that has a 2263 projection and i want to change it to 4326 using pyproj?

问题 How do i use the pyproj module to take a file from a path and just change it automatically? The file also includes multiple rows of data. It would probably need to run a loop on all the coordinates and just change them? I've added this code into the question based on your suggestions. import os,shutil import json from pyproj import Proj,transform #Create Desktop Folder path= os.path.expanduser('~/Desktop/NAD83_to_WGS84') path2=os.path.expanduser(path+'/EPSG_4326.json') #Any file path for

官网地址: https://developers.arcgis.com/javascript/latest/guide/create-a-starter-app/ 本节目标:如何构建一个显示2D地图或3D场景的简单应用。 构建以2D或3D显示地理数据的地图绘制应用程序,第一步是创建一个包含底图的地图。 可以使用ArcGIS Online中托管的底图,也可以将自己的底图与自定义样式一起使用。 如果要将数据添加到地图,则可以将点、线、多边形和文本添加为图形,或者,对于较大的数据集,可以使用要素图层添加数据。 定义地图后,可以使用MapView将其显示为2D或使用SceneView将其显示为3D。 视图负责显示地图,处理用户交互以及设置地图的位置。 目录 1、创建一个HTML页面 2、添加CSS和API的引用 3、创建2D地图或3D场景 4、完整示例——2D map(MapView) 5、完整示例——3D scene(SceneView) 1、创建一个HTML页面 <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="initial-scale=1, maximum-scale=1, user-scalable=no"> <title>ArcGIS JavaScript

Arcgis API 离线安装 1. API离线部署 将离线包下载到本地之后解压,将解压后的文件夹放到tomcat下 2. API离线配置 (1)打开下载api里面的init.js文件,目录是:\arcgis_js_api\library\3.20\3.20\init.js,查找 baseUrl: 将后面对应的路径替换,这个路径需要完整的访问路径,比如:http://127.0.0.1:8080/arcgis_js_api/library/3.20/3.20/dojo 具体的根据实际情况进行修改即可 (2) 打开下载api里面的dojo.js文件,目录是:\arcgis_js_api\library\3.14\3.14\dojo\dojo.js 查找 baseUrl: 将后面对应的路径替换,这个路径只需要相对访问路径即可,比如:…/arcgis_js_api/library/3.20/3.20/dojo, 3. API引用 配置修改完成之后API的引用方式示例如下,只需引用一个css样式和init.js文件即可正常使用API,具体使用方式可参照demo < link rel = "stylesheet" href = "http://127.0.0.1:8080/arcgis_js_api/library/3.20/3.20/esri/css/esri.css" / > <
