I love geology maps. After working on the Mars Geology map project, I wanted to see if I could do something similar closer to home. I wanted to use geoc as much as possible to create a GeoPackage database of WA State geology data with embedded styles that would work in QGIS and geoc.

Usually writing a Java application requires using Maven or Gradle. While both are great tools for large projects, they are too complicated for small scripts. jbang is a new tool that lets you create scripts or simple applications with Java. I will create a geospatial command line tool using jbang and the Java Topology Suite (JTS).
