    16  * With ArcGis 
    17 Use the french limits (see ["French Boundaries"] in RGF93[[BR]] 
    18 In QuantumGis, connect the ROE database and add the obstacle_referentiel layer[[BR]] 
     16 * With !ArcGis 
     17Use the french limits (see ["French boundaries"]) in RGF93[[BR]] 
     18In __!QuantumGis__, connect the ROE database and add the obstacle_referentiel layer[[BR]] 
    1919Clic right on the layer "Sauvegarder comme shapefile" with Fichiers de type : Shapefiles (*.shp), Codage=UTF-8 > ok 
    20 and choose "Système de coordonnées de référence" = RGF93/Lambert93 (because the french boundary layer is in this system). 
    21 In ArcGis, add the two layers : 
    22   - ROE_EDA.shape 
    23   - GEOFLADept_FR_Corse_AV_L93\DEPARTEMENT.shp 
    24 Use Analysis Tools > Extract > Clip 
    25 Input Features : ROE_EDA 
    26 Clip Features : DEPARTEMENT 
     20and choose "Système de coordonnées de référence" = RGF93/Lambert93 (because the french boundary layer is in this system).[[BR]] 
     21In __!ArcGis__, add the two layers :[[BR]] 
     22- ROE_EDA.shape[[BR]] 
     23- GEOFLADept_FR_Corse_AV_L93\DEPARTEMENT.shp[[BR]] 
     24Use Analysis Tools > Extract > Clip[[BR]] 
     25Input Features : ROE_EDA[[BR]] 
     26Clip Features : DEPARTEMENT[[BR]]

    2828If you want you can choose a "XY Tolerance", because some points in the ROE are in France but they are at the limit.
