049] How to Import WKT and XY Coordinate CSV Files in Global Mapper (Points, Lines, and Polygons)
Overview of CSV-Based Geometry Import in Global Mapper Learn how to import points, lines, and polygons from CSV files using WKT and Coordinate List formats. While Shapefiles are standard, CSV files offer a lightweight and human-readable alternative for storing GIS data. This tutorial demonstrates how to correctly configure Global Mapper to interpret text-based geometry definitions (WKT) and consecutive coordinate lists, ensuring your data is accurately positioned on the map. Recommended Audience: GIS Analysts, Data Preprocessors, and Global Mapper users managing non-standard data formats. Previously, we covered how to import points using CSV files. Today, we will explore how to import more complex geometries—points, lines, and polygons (areas)—stored within a CSV file. You might wonder why anyone would store line or polygon data in a CSV file when the SHP format is so well-supported. There are several good...
