2.9. Use custom styles in Mapfile

Vector data can be divided into three types: point, line and surface. The simplicity of the data type structure gives the diversity of expression. In MapServer, you can set styles in various dimensions such as color, size (thickness), and transparency for points, lines, and surfaces.

2.9.1. Point

The Mapfile used is:
