====== LARCOS Overwrite points tool ======

===== Preparetion =====

Draw the areas on the map by [[:geoscene3d:profiles_and_regions:creatingregions|]] or use shape files and convert to regions like this [[:geoscene3d:project_content:objects:region:create_a_region_from_a_shape_file|]].

===== Step-by-step workflow =====

From the Main menu open the Tool

{{:geoscene3d:building_a_layered_model:pointtool_gui.png|}}

  - Choose the overwrite area definition:
      * **Overlap:**  overwrite only interpretation points located within the overlap between the source and destination areas.
      * **All:**  overwrite all interpretation points in the source area.
  - Select the one or two model areas.
  - Optionally select an exclude area. Interpretation points located inside this area will not be deleted and none will be inserted.
  - Select the source interpretation database containing the interpretation points to copy.
  - Select the destination interpretation database where the interpretation points will be overwritten within the selected area. Existing interpretation points in the destination database will be deleted, and interpretation points from the source database within the selected area will be inserted in the destiantion database.
  - The tool checks that the source and destination interpretation databases contain matching tables with the same names and EPSGs. The EPSG for the points is shown in paranthesis after the table name, e.g. (25832).
  - Select the tables.
  - Choose whether to create a backup of the destination interpretation database before replacing interpretation points.
  - Run the replacement or backup-and-replacement process.
  - Existing interpretation points in the destination interpretation database are overwritten with the corresponding interpretation points from the source interpretation database for the selected area and tables, except for interpretation points inside the selected exclude area.


===== Overlap of Area 1 and 2 using Exclude Area  =====

The resultant area is shown as the hatched area. The overwrite is using this resultant area: 
  - All Points in the destination database within this area are deleted
  - Points from the source database within this area are inserted into the destination database

===== All Area 1 using Exclude area =====

The resultant area is shown as the hatched area. The overwrite is using this resultant area: 
  - All Points in the destination database within this area are deleted
  - Points from the source database within this area are inserted into the destination database
