Getting Started with GeOxygene Plugin for OpenJUMP
===================================================

Plugin Network matching
****************************

Playing
--------------

1. Download demo data :
   
   * Network 1 : http://svn.code.sf.net/p/oxygene-project/code/main/trunk/geoxygene-data/ign-echantillon/bdcarto/BDC_3-1_SHP_LAMB93_X072-ED111/RESEAU_ROUTIER/TRONCON_ROUTE.zip
   
   * Network 2 : http://svn.code.sf.net/p/oxygene-project/code/main/trunk/geoxygene-data/ign-echantillon/bdtopo/72_BDTOPO_shp/BDT_2-0_SHP_LAMB93_X062-ED111/A_RESEAU_ROUTIER/ROUTE.zip

2. Start OpenJUMP.

3. Load both shapefiles

4. Select menu "GeOxygene >> Appariement >> Appariement de réseaux".

5. Launch matching 

   .. container:: centerside
   
      .. figure:: /documentation/resources/img/openjump/GeoxygeneOpenJump01.png
         :width: 450px
       
         Figure 1 : Dataset
               
6. Results of matching will be displayed on windows.

   .. container:: centerside
   
      .. figure:: /documentation/resources/img/openjump/GeoxygeneOpenJump02.png
         :width: 450px
       
         Figure 2 : Results of matching
      
7. Finish.

Plugins "quality"  
******************

Presentation
--------------

Several plugins concern the "geoxygene-quality" module :

- « PlugInEstim » : this plugin concern the EstIM model developed during the PhD of (Girres,
  2012). Allows the computation of different impacts (projection, terrain,
  polygonal approximation, digitizing error, generalisation) for lengths and
  areas.

- « PlugInComparison » : a plugin to compute differences between datasets. 
  Automatic or manuel matching are provided for polygons and linestrings. Different methods to
  normalize linestring comparisons are also proposed (extremity cutting,
  section cutting)

- « PlugInMountainGridDetection » : a plugin to facilitate the delineation of mountainous areas
