walls_parse

A Python parser for cave survey data in .srv format, handling backsight/foresight shots with LRUD (Left/Right/Up/Down) measurements. This converts Walls files generated by TopoDroid into the format used by the Cave Research Foundation (CRF).

Overview

walls_parse.py processes cave survey data files and extracts shot information including:

• Backsight and foresight stations
• Distance and azimuth/inclination measurements
• LRUD wall measurements at station locations
• Support for various shot patterns including partial backsights

Usage

python3 walls_parse.py <input_file.srv>

File Format

The parser works with .srv survey files. See example-in.srv for input format and example-out.srv for expected output.

Features

• Handles full 4-LRUD backsight shots
• Supports partial backsight patterns with splay inference
• Flexible shot pattern matching
• Verbose output mode for debugging
