Change the coordinate system in ArcGis

Change the coordinate system of an input Dataset to a new Output Dataset with a newly defined coordinate system, including the datum and spheroid.

Ecoregions - Geographic Coordinate System : GCS_sphere_ARC_INFO this coordinate system doesn't exist in the srid in postgis. So we had to use Arcgis to change the coordinate system into ETRS1989 LAEA (srid=3035 in postgis).

Add the different layers :

• dmeereea4074i_tic
• dmeereea4074i_label
• dmeereea4074i_arc
• dmeereea4074i_polygon

In the ArcToolbox select : Data Management Tools > Projections and Transformations > Feature > Project

Open Project and :

• "Input Dataset or Feature Class" : select the layer to reproject (dmeereea4074i_arc)
  
• "Output Dataset or Feature Class" : a new name is given by default (or change it)
  
• In "Output Coordinate System" : you'll have to choose the ETRS1989 LAEA coordinate system
  Output Coordinate System > XY Coordinate System > Select > Projected Coordinate Systems > Continental > Europe > Choose : ETRS1989 LAEA
