rivlib-utils

Collection of utilities for working with Riegl rxp data files. Includes:

  • ri-inclination: extract inclination data.
  • ri-meta: extra metadata information, as json.

Example

Running:

ri-inclination file:140123_202748.rxp

will produce output like:

Time,Roll,Pitch
91.8223,-0.286,-0.275
92.8221,-0.285,-0.265
93.9119,-0.288,-0.274
94.9033,-0.286,-0.261
95.8631,-0.287,-0.262
96.8597,-0.283,-0.276
97.8537,-0.289,-0.268
98.8159,-0.286,-0.272
99.9358,-0.290,-0.266
100.8962,-0.286,-0.277

This output is on stdout, and can be piped to a file for later use.

Time reference

The time value produced by ri-inclination is the scanner's internal timestamp. It is possible to retrieve GPS time from rxp files, but this is not implemented as of yet and is an area for future improvement.

Installation

rivlib-utils is known to work on Ubuntu 12.04 with rivlib 3.5rc1, though it should work with many unix builds and rivlib versions. There are no builds or official releases of rivlib-utils, so you must build from source.

First, aquire rivlib from the RIEGL software download site and make sure it is present on your system. Then, follow the standard Github+cmake+make build sequence, pointing CMake to your version of rivlib:

git clone https://github.com/gadomski/rivlib-utils.git
cd rivlib-utils
mkdir build
cd build
cmake .. -G "Unix Makefiles" -DRiVLib_DIR=/path/to/your/rivlib-rc1_35-x86_64-linux-gcc43/cmake
make

The utilities will build in the bin/ directory. If you'd like to use the utilities without specifying an absolute path, run:

(sudo) make install

You may need the sudo if your /usr/local is not writable by your user.

This software could reasonably be expected to work on a Windows system, since the only dependency is rivlib which comes in a Windows build. You're on your own for figuring out how to make that work, however.
