Tools to Read 'Lowrance' Binary Track Files

Description

Lowrance' (http://www.lowrance.com/) chart plotters use an ugly but straightforward binary format to encode their tracks. Tools are provided to read 'SL2' files (and, very likely 'SLG' and 'SL3' files, too).

What's Inside The Tin

The following functions are implemented:

• read_sl2: Read Lowrance binary track files
• read_sl2_cpp: A "No Frills" Faster Version in C++ (uncomment things in the package if you want this as the OP was having issues on Windoews with Rtools) — look in old-source for the CPP version

Installation

devtools::install_git("https://gitlab.com/hrbrmstr/arabia")
