5.3. Tutorial data
The following sections contain step by step information on how to complete certain GIS tasks using both ArcGIS and QGIS. To follow these steps, the zip file “GISBEEBOOK”, can be downloaded from (http://www.coloss.org/beebook/to be determined). Unzip the data and save them in a location with a few gigabytes of space available. Within the GISBEEBOOK folder, there are two sub-folders, one for ArcGIS and one for QGIS, each containing the same original data. When working through each tutorial, it is recommended that you save your outputs in the respective software’s folder to help with file and data organisation. Both folders are located within the GISBEEBOOK folder. The GISBEEBOOK zip file contains the two folders (ArcGIS and QGIS) with the following data layers in each:
- Point file: This file was created solely for the purpose of this
exercise and does not represent the actual locations of honey bee colonies.
- ArcGIS: An Excel file containing point locations: colony_locations.xlsx.
- QGIS: A comma-separated text file (*.csv) containing the same point locations: points-table.csv.
- A shapefile containing commune information: commune_boundary_FR.shp (plus 6 other file extensions which must stay together). This data comes from a clip of the Vector200 Swisstopo (Swisstopo, 2013) data layer which is provided to the readers of this paper for testing purposes only and cannot be shared or used for data analysis purposes outside of this tutorial. Communes are a type of administrative unit in Switzerland.
30 m DEM:
- ArcGIS: Located within the DEM folder: aster30_frib_ch.tif (along with 4 other extensions that should be kept together with this file for georeferencing purposes).This DEM was a free download from the ASTER GDEM website (http://gdem.ersdac.jspacesystems.or.jp/). The projection was previously changed to the Swiss coordinate system (CH1903) and clipped to the area around Fribourg.
- QGIS: ASTER30_WGS84.tif. Also downloaded from the ASTER GDEM website but left in the WGS 1984 coordinate system.
