In diegoalarc/GeodesiCL: Geometric Geodesy Functions
GeodesiCL: A little journey into Geometric Geodesy.
Attention: We are ready to go!!
To begin with
This package was created to introduce topographical and related engineers in the area of Topography and Geodesy as a basic introduction to Geometric Geodesy applying the necessary basic formulas.
This was a project created between Diego Alarcón and Karla Riquelme seeing the need to introduce the new generation of professionals in the learning of software language and in turn present free software.
Installation
Install system dependencies
Please make sure that the GDAL libraries are installed on your system:
- Windows: use the OSGeo4W installer.
- Ubuntu:
sudo apt install gdal-bin libgdal-dev
- MacOS:
brew install gdal --HEAD or brew install gdal
For more information on GDAL installation Click here!
We currently have two ways to install this package, as it is not yet finalized for posting to CRAN Project.
First option
After we already have the system dependencies, to use this package you should install R & RStudio. Next, you need to install the devtools package in order to start with the installation of the GeodesiCL package, then just copy and paste the following command into the RStudio console:
install.packages("devtools")
devtools::install_github("diegoalarc/GeodesiCL")
Second option
If you already have experience using R & RStudio, you could just copy the following command:
install.packages("GeodesiCL")

Functions
Here you can see the functions contained in the package. Is it possible to read its description by copying to the console ?function or if you want to see an example just using example(function) like the following:
Check out each example, since most functions work with data.frame that has a specific order for its data.

Interesting fact
As entertaining fact, the name of the package is because geodesy is written geodesia in Spanish and CL represents the acronym of my country Chile but strangely you can see an A writing GeodesiA in Spanish (lol).
