las-converter的Python项目详细描述
LAS 2.0读卡器和JSON转换器
这个包对于读取las文件并将其转换为pythondict和json非常有用。
las（log ascii标准）是一个结构化的ascii文件，包含日志曲线数据和头信息。更多detail。

prints. This was the best information available at the time. Every attempt should be made to track down the original films. .Dec. 12,1990 John Doe, Petrophysics

安装
pip install las-converter
如何使用
具有file输入的LAS转换器。见here。
fromLASimportConverterc=Converter()# create converter objectlog=c.set_file("file.las")#return LogWrapper# get sectiondata=log.dataversion=log.versioncurve=log.curveparameter=log.parameterwell=log.wellother=log.other# or get dictionarylog_in_dict=log.get_dict()# or print on json format and save to disklog_in_json=log.get_json("outfile_name")
服务器应用程序（烧瓶）
输入为stream的las转换器。见here。
# server app for handling uploadfromflaskimportrequestfromLASimportConverter@app.route('/upload',methods=['GET','POST'])defupload_file():ifrequest.method=="POST":f=request.files['file']# read streamstream=f.stream.readlines()# code for Las Converterc=Converter()log=c.set_stream(stream)# or get only assci/datadata=log.data
输出
