Modify geometry

With OrbisGIS, you can edit a vector layer and modify his objects.


Load a layer in the Geocatalog and drag & drop it in the TOC (e.g : load the layer "dep_france_dom.shp").

In the TOC, select it and make a right-click -> Start Edition


Before Edition

After -> The edition begins: the name of the layer is in italics

When you are in edition's mode, a new toolbar appears in the menu. These toolbar is function of the vector type of your layer.


a- For the "polygon" layer:


 

Delete an object : select it and click on the red cross in the tool bar

Draw a polygon : left-click for each vertex you want. When you want to close the polygon, right-click --> Terminate polygon. If you want to cancel your action, right-click --> Cancel

Draw a multipolygon : draw different polygons (cf "draw a polygon"). When you want to close the multipolygon, right-click --> Terminate multipolygon. If you want to cancel your action, right-click --> Cancel

Add a vertex : select the object which you want to add a vertex. Click on the appropriate button in the toolbar and move the mouse next to your object. OrbisGIS show you a new vertex and modify the polygon's outlines. Right-click to add the vertex.

Delete a vertex : select the object which you want to delete a vertex. All the vertex appears. Click on the appropriate button in the toolbar and click on the vertex which you want to delete.


b- For the "line" layer :

Delete an object : same as "polygon layer"

Draw a line : left-click for each vertex you want. When you want to close the line, right-click --> Terminate line. If you want to cancel your action, right-click --> Cancel

Draw a multiline : draw differents line (cf "draw a line"). When you want to close the multiline, right-click --> Terminate multiline. If you want to cancel your action, right-click --> Cancel

Add / Delete a vertex : same as "polygon layer"


c- For the "point" layer :

Delete an object : same as "polygon layer"

Draw a point : left-click for each point you want.

Add / Delete a vertex : theses buttons have no reasons to be here (there will be removed in the next version of OrbisGIS).
