Lithica Mapper

Lithica Mapper is a professional geological mapping tool designed specifically for Android tablets. Optimized for intensive stylus and touch gesture use, it allows geologists, researchers, and students to digitize and structure maps in the field with centimeter-level accuracy.

NOTE: This version is currently in Closed Testing. We welcome your feedback to help us fix bugs and improve the drawing tools before the general release.

Key Features:
• PRECISE GEOLOGICAL DRAWING: Draw and edit geological contacts, faults, and units (polygons) freehand, by vertices, or in mixed mode. Designed to ignore accidental palm touches and respond to stylus input.
