基于Python的MODIS卫星秸秆焚烧监测——以哈尔滨市为例

Monitoring of MODIS Satellite Straw Burning Based on Pythons——Take Harbin as an Example

介绍了利用Python语言,从NASA网站上实时下载指定时间段的Shapefile格式的地表高温数据,并对数据进行地理处理.ArcMap软件是高度可视化的.同时,它也是创建地图文档、图层以及地图输出的首选软件.通过ArcMap创建地图文档之后,在脚本中通过ArcPy制图模块实现制图任务的自动化.最后,在程序中利用腾讯逆地址解析API接口,将研究区内的火点经纬度转换成对应的地址,并将数据存储到MySQL数据库,以便以后查询分析,统计.

In this article, the use of the python language to download in real time the Shapefile format of the surface high temperature data in a specified time period from the NASA website is introduced, and the data is processed geographically. ArcMap software is highly visual. It is also the preferred software for creating map documents, layers, and map output. After the map document is created by ArcMap, the mapping task is automated in the script through the ArcPy mapping module. Finally, in the process of using tencent reverse address resolution API interface, the fire in the longitude and latitude converted into the corresponding address is studied, and the data is stored in the MySQL database. It is query for later to be analyzed and counted.
