# data folder. | ||
|
||
### Occurrences | ||
Contains an empty 'config.yml' file. Once an sdmdl object has been created once this file will contain the file paths to | ||
the detected occurrence tables and raster layers, and a number of model hyper parameters. | ||
|
||
The substructure will include a folder ([filtered](filtered)) with files with | ||
occurrences, one file per species. The files are formatted as per | ||
[this](https://github.com/naturalis/trait-geo-diverse-ungulates/blob/master/data/filtered/Aepyceros_melampus.csv) | ||
example. The data are collected from GBIF as DarwinCore archives | ||
(store the DOI for each query!) from which we retain the following columns: | ||
|
||
1. gbif_id | ||
2. taxon_name | ||
3. decimal_latitude | ||
4. decimal_longitude | ||
|
||
### GIS data | ||
|
||
There will also be a folder ([GIS](GIS)) with GIS layers as input for the niche | ||
modelling. The resolution will be 5 arcminutes. Which layers is to be determined. | ||
The configuration file can be edited using a simple text editor (e.g. notepad ++). |

## Topography | ||
Median elevation variables were extracted from the [Harmonized World Soil Database ](http://www.fao.org/soils-portal/soil-survey/soil-maps-and-databases/harmonized-world-soil-database-v12/en/) and have a spatial resolution of 30 arcseconds. The topographic wetness index and the terrain roughness index are extracted from the [ENVIREM](https://deepblue.lib.umich.edu/data/concern/data_sets/gt54kn05f) dataset and have a spatial resolution of 30 arcseconds. | ||
### Datasets | ||
1. Slope | ||
2. Aspect | ||
![](images/slope.PNG) | ||
## Soil | ||
The soil characteristics are extracted from the [Land-Atmosphere Interaction Research Group](http://globalchange.bnu.edu.cn/research/soilw) with a spatial resolution of 5 arcminutes. | ||
|
||
1. Bulk density | ||
2. Clay percentage | ||
3. pH CaCL | ||
4. Organic carbon | ||
|
||

|
||
## Ecoregions | ||
Separate raster maps representing the world's terrestrial ecoregions were created from the [The Nature Conservancy's](http://maps.tnc.org/gis_data.html) world ecoregion's shapefile. | ||
1. Boreal Forests and Taiga | ||
2. Deserts and Xeric Shrublands | ||
3. Flooded Grasslands and Savannas | ||
4. Inland Water | ||
5. Mangroves | ||
6. Meditteranean Forests, Woodlands and Scrubs | ||
7. Montane Grasslands and Shrublands | ||
8. Rock and Ice | ||
9. Temperature Broadleaf and Mixed Forests | ||
10. Temperature Conifer Forests | ||
11. Temperate Grasslands, Savannas and Shurblands | ||
12. Tropical and Subtropical Coniferous Forests | ||
13. Tropical and Subtropical Dry Broadleaf Forests | ||
14. Tropical and Subtropical Grasslands, Savannas and Shrublands | ||
15. Tropical and Subtropical Moist Broadleaf Forests | ||
16. Tundra | ||
|
||
## Ecoregion attributes | ||
Additional attribute metrics per ecoregion from the The World Atlas of Conservation extracted as shapefiles from [Databasin](https://databasin.org/maps/new#datasets=43478f840ac84173979b22631c2ed672) and rasterized. | ||
1. Habitat fragmentation | ||
2. Human accessibility | ||
3. Human appropriation | ||
4. Mammal species richness | ||
5. Plant species richness | ||
|
||
## Species co-occurrence. | ||
Species occurrence raster maps created for 124 species, list of species can be found in [Taxa list](https://github.com/naturalis/trait-geo-diverse-dl/blob/master/data_GIS_extended/data/SQL_filtered_gbif/taxa_list.txt) | ||

# Stacked raster datasets | ||
## env_stacked | ||
The [env_stacked](env_stacked) folder contains the environmental variable rasters stacked into a single GeoTiff, the file itself is not uploaded on Github as it's size is too large. Next to this, the folder contains a text file containing the variable descriptions for each of the 186 bands in the GeoTiff. | ||
|
||
## stacked raster clips | ||
A clip was made of the GeoTiff for each species, based on its IUCN range. | ||
However, this clip was not uploaded to Github as file sizes were too large. | ||
Contains the 'world_locations_to_predict.csv' table that is used during the data preparations. |
