 Morazán, in central Honduras, northeast of Tegucigalpa; have a total area of 24,040 hectares. Currently the PNLT is co-managed by [Instituto de Conservación 
 Forestal (ICF)](https://icf.gob.hn/) and [Fundación Amigos de **La Tigra** (AMITIGRA)](https://www.amitigra.com/), in the past the municipalities of Santa Lucia, Valle de Ángeles and Cantarranas were also 
 co-managers of the Park.

 ## Convert **sf objects** to [geopackage](https://www.geopackage.org/) format
 
-Although I would prefer that we work our spatial analysis in R, because in this way we ensure the [reproductivility](https://ropensci.github.io/reproducibility-guide/sections/introduction/) and access the the great [R Ecosystem](https://cran.r-project.org/web/packages/available_packages_by_name.html). I understand that some users will like to use this spatial data in other software like [QGIS](https://www.qgis.org/en/site/), this can be done converting from the **sf object**, store in the package **pnlt** in [rda](https://www.loc.gov/preservation/digital/formats/fdd/fdd000470.shtml) format, to other spatial data formats such as [geopackage](https://www.geopackage.org/). The function **downloadLaTigra()** make this possible in one step. The data will be downloaded into your working directory in a folder named **PNLTdata**, with 5 geopakage spatial databases named after the thematic groups used in the package.
