The Merge Wizard enables you to merge several files into one.

  • Currently supported formats are ESRI Shapefiles for vectors and GeoTiff files for rasters.
  • If source files are stored in the File System then destination file has to be in the File Manager too. If all source files are stored in the Database, then destination file has to be in the Database too. If one of the source files is stored in the File Manager and other in the database, destination file has to be stored in the File Manager. Note that layers stored in the File Manager are not editable.
  • Source layers have to have same geometry type (point, line or polygon). It is not possible to merge e.g point and polygon.
  • It is also possible to merge data collected with MDC. MDC data is stored as a table in the Database.

To merge files, follow steps below:

  1. Select Merge Wizard from the Tools tab.
  2. NMT_Merge_Wizarda

  3. Browse files you wish to merge from the File System or Database.
  4. NMT_Merge_Wizard1a

  5. Browse Destination for a merged file. Follow the steps below depending if your layers are stored in File System or Database.

Layers stored in the File Manager

  1. For layers stored in the File Manager, select File Manager from the left side, write a name of the merged file in the File name box and click Select.
  2. merge

  3. Merge Wizard should look like this:
  4. merge1

  5. Click Merge. Merged file is stored in the File Manager.

Layers stored in the Database

  1. Browse source, select Database from the left side. Create a new table where data will be merged.
  2. merge3

  3. Define only the table name and geometry (point, line or polygon depending of the source files). Save the empty table.
  4. Select source layers from the Database datasource.
  5. Browse Destination file. Select Database and created file where data will be stored.
  6. Click Save. Merged file is stored in the Database.

You can add the merged layer to a map with Add layer option from the Layer tab. Select File System or Database as a datasource depending on where merged layer is stored.
