# Introduction

[QGIS](https://qgis.org/en/site/) is an Open Source Geographic Information System (GIS) licensed under the GNU General Public License.

The aim of this document is to present some recipes about importing and exporting vectors, and treatment and exploration of spatial data. I plan to add more recipes on vector styling and map composition. 

This is a brief introduction to QGIS, as such, it does not replace in any maner the [QGIS User Guide](https://docs.qgis.org/3.4/en/docs/user_manual/). I also recommend you visiting the [StackExchange](https://gis.stackexchange.com/) chanel, where you can get support on questions related to QGIS.

The data used to illustrate the recipes presented in this document come from the [Portail données ouvertes Montréal](http://donnees.ville.montreal.qc.ca/); particularly, the selected data from this site is under the license [Creative Commons Attribution 4.0 International](https://creativecommons.org/licenses/by/4.0/).

To follow the recipes presented in this document, please download the accompanying files from my [GitHub page](https://github.com/iviveros/QGIS_Data).
