Join ROE - CCM

Puttin geobs into the CCM

Initially, the database was located in another table, below we just copy the table shema roe into the ccm21_eda database

We have to reproject our data

Select only the dams within France

Extract the data within the french boundaries

this is ticket #45

With ArcGis

Use the french limits (see French boundaries) in RGF93
In !QuantumGis, connect the ROE database and add the obstacle_referentiel layer
Clic right on the layer "Sauvegarder comme shapefile" with Fichiers de type : Shapefiles (*.shp), Codage=UTF-8 > ok and choose "Système de coordonnées de référence" = RGF93/Lambert93 (because the french boundary layer is in this system).
In !ArcGis, add the two layers :

• ROE_EDA.shape
  
• GEOFLADept_FR_Corse_AV_L93\DEPARTEMENT.shp
  

Use Analysis Tools > Extract > Clip
Input Features : ROE_EDA
Clip Features : DEPARTEMENT

If you want you can choose a "XY Tolerance", because some points in the ROE are in France but they are at the limit. (maybe 300meters?).

With QGis

first change projection to ERTRS 89 write ogr2ogr -f formatdst_datasource_name src_datasource_name -a_srs <actual projection> -t_srs <reprojected data> Launch in OSGeo4W command shell

CD C:\Documents and Settings\cedric\Mes documents\Migrateur\eda\couches_SIG\france
C:\OSGeo4W\bin\ogr2ogr DEPARTEMENT_3035.shp DEPARTEMENT.shp -s_srs "EPSG:2154" -t_srs "EPSG:3035"

The shape file DEPARTEMENT_3035.shp is created with right projection Connect the ROE database and add this newly projected obstacle_referential layer
Process Add the file GEOFLADept_FR_Corse_AV_L93\DEPARTEMENT.shp (layer>add a vector layer)
Tools > Geoprocessing tools > Clip

Build a view allowing to know the score of the different dams
