== Download on ccm on the web site ==

If you don't have a login and a password create it.[[BR]]
And select the data you want to add. Use the projection system : ETRS 1989 LAEA[[BR]]

== Change the format with !ArcGis ==

In !ArcCatalog, open the data (for example CCM21_LAEA_RiverBasins\ccm21\LAEA_RiverBasins.gdb) and clic rigth on LAEA_RiverBasins.gdb > Export > To Shapefile (multiple)[[BR]]
and choose the "Output Folder" where the data will be stored.[[BR]]

Unzip the folder.

== Append the different shape files ==
We have obtained shapefiles from different sources, folder (http://ccm.jrc.ec.europa.eu/images/CCM2_Windows2b.JPG), and it's easier to combine them into one single shapefile for ease of analysis and mapping.[[BR]]
This process is known as "merging" within ArcGIS.[[BR]]
