How to overlay shapefile data on PyGMT Maps

The PyGMT library in Python simplifies the creation of high-resolution topographic maps by providing built-in shorelines, country borders, and topographic data. By integrating geopandas, PyGMT enables users to overlay custom shapefile data, making it easy to highlight specific regions on a map. In this post, we demonstrate how to use county boundary data from Taiwan’s government portal to overlay on a high-resolution map of Taiwan, focusing on selected counties. This method provides a flexible, powerful approach for creating visually striking maps with customized geospatial information, applicable to various regions and datasets.

Topographic map clipped by coastlines in Python

Learn how to create visually compelling relief maps in Python by clipping topographic data to specific geographic boundaries, such as coastlines. This tutorial walks you through the process of using matplotlib and Basemap to focus your visualizations on land features within the Taiwan coastline, or alternatively, highlight bathymetric features by masking the land.

Plotting the geospatial data clipped by coastlines in Python

In this post, we explore how to perform geospatial interpolation using the Ordinary Kriging method and visualize the results within the coastline borders of Taiwan. Learn how to efficiently handle irregularly distributed geospatial data and automate the process of clipping data outside geographic boundaries for more accurate and meaningful visualizations.
