Exploring Geospatial Data Visualization Based on Python.

OpenStreetMap (OSM), as a typical representative of crowdsourced geographic information data, covers a large amount of open source geographic information data, which provides freely editable world-class geographic data for realizing information mining, analysis and visualization of geospatial data. Based on the geographic information data from the official website of OSM, this paper uses Python's geographic information data processing technology, geospatial data visualization technology and layer overlay method based on vector data analysis algorithm to realize visualization and information annotation of various types of geospatial data, providing reliable data processing, visualization and analysis methods for domestic resource exploration, transportation, epidemic prevention and control and other fields.
