Map matching of taxi trajectory data under offline OSM data conditions
Map matching of taxi trajectory data under offline OSM data conditions Preface: In the process of studying the road network matching of Python taxi GPS data (TransBigData + leuvenmapmatching) written by senior Xiaoxu of traffic data, I found that the osmnx library is difficult to obtain a complete road network of a city or a […]
Revealing the Mysterious String Matching Tool-Regular Expressions
Regular expressions, also known as regular expressions (often abbreviated as regex, regexp or RE in code), are a powerful tool for matching, finding, and replacing text. It can automate text processing by matching strings with specific patterns. In many programming languages, regular expressions are widely used in text processing, data analysis, web crawling and other […]

Python-match continuous content based on keywords
Use PyQt5 to generate an executable small program: match the content in GGA format from the start keyword to the end keyword range, support multiple selection of files, and clear the copied files generated during the process. The GGA file is as follows: $GPZDA,063052.00,16,10,2023,,*61 $GPGGA,063052.00,4349.7377413,N,12509.8354912,E,4,40,0.6,222.928,M,0.00,M,01,2445*69 $GPZDA,063053.00,16,10,2023,,*60 $GPGGA,063053.00,4349.7377412,N,12509.8354914,E,4,40,0.6,222.926,M,0.00,M,01,2445*61 $GPZDA,063054.00,16,10,2023,,*67 Mini program interface: Run pyinstaller -F -w […]
