Python将JSON数据转换为ArcGIS Shapefile的实现方案

核心代码与数据解析逻辑

import shapefile
import json
import os
 
#shapefile="polygon.shp";
#jsonfile="社区网格.json";
 
def run():
  data=readJSON()
  datalist=data["list"]
  file=shapefile.Writer(target="社区网格.shp",shapeType=shapefile.POLYGON,autoBalance=True);
  #设置属性信息
  file.field('nere', 'C', '40') #'SECOND_FLD'为字段名称，C代表数据类型为字符串，长度为40
  file.field('fileName', 'C', '40')
  file.field('url', 'C', '40')
  file.field('photo', 'C', '40')
  file.field('netGrnereNum', 'C', '40')
  file.field('color', 'C', '40')
  file.field('num', 'C', '40')
  file.field('lat', 'C', '40')
  file.field('lon', 'C', '40')
  file.field('togriga', 'C', '40')
  file.field('gudumji', 'C', '40')
  file.field('memo', 'C', '40')
 
  #写入数据
  for item in datalist:
    nere=item["nere"]
    fileName = item["fileName"]
    url = item["url"]
    photo = item["photo"]
    netGrnereNum = item["netGrnereNum"]
    color = item["color"]
    num = item["num"]
    lat = item["lat"]
    lon = item["lon"]
    togriga = item["togriga"]
    gudumji = item["gudumji"]
    memo = item["memo"]
    polysStr = item["hotinfo"]
    polys=parsing(polysStr);
    #写入
    file.poly(polys=polys)
    file.record(nere,fileName,url,photo,netGrnereNum,color,num,lat,lon,togriga,gudumji,memo)
    print("-------写入成功---------")
  #保存文件
  file.save("社区网格.shp")
 
#读取json文件
def readJSON():
  f = open("社区网格.json", "r",encoding="utf-8") # 设置文件对象
  _str = f.read() # 将txt文件的所有内容读入到字符串str中
  f.close() # 关闭文件
  print("读取json完成")
  if _str.startswith(u'\ufeff'):
    _str = _str.encode('utf8')[3:].decode('utf8')
  data = json.loads(_str,encoding='utf8')
  return data;
  #print(data)
 
#数据解析
def parsing(text):
  data=[]
  strs=text.split(",");
  for line in strs:
    xy=line.split(" ");
    x_y=[float(xy[0]),float(xy[1])]
    data.append(x_y)
  _data=[];
  _data.append(data)
  return _data;
 
 
if __name__=="__main__":
  print("执行程序！！！");
  run();
  print("程序结束！！！");
