The Map Assembler tool allows you to assemble a new map in one of two ways:

• by browsing to existing GeoPDF files/geospatially-aware PDF files and selecting the files to be included

• by drawing a polygon on an index map and extracting from the included area the map tiles to be included in the new map

When you assemble a new map, each file or map tile is assembled as its own separate layer, allowing you to retain the layers and object data. The Map Assembler tool also allows you to add additional layers to a currently open map.

For instructions on how to access the Map Assembler tool, see Accessing the GeoPDF Composer Toolbar.

Assembling a map from existing GeoPDF or geospatially-aware PDF files

Selecting files

• From the GeoPDF Composer Toolbar, click the Map Assembler tool.

• Click Browse to open the Select PDF Files to assemble dialog box.

• From the Look in list box, navigate to the location of the GeoPDF files or geospatially-aware PDF files that you want to assemble into a new map.

• Select the files for the layer assembly and then click Open.

• In the Default Layer Name group box, choose either File Name or Map Frame Name as the name to display in the layer properties.

Specifying GeoPDF Toolbar compatibility

From the Make Compatible With list box, click the version of GeoPDF Toolbar with which your assembled map must be compatible. The default value is the GeoRegistration encoding method you specified in the GeoRegistration Format Compatible With list box on the TerraGo Preferences dialog box. If you did not specify an encoding method, the default for the GeoRegistration Format Compatible With list box is GeoPDF Toolbar 3+ (OGC).

GeoPDF Toolbar 3+ (OGC)

• GeoPDF Toolbar 3+ (OGC) requires that the maps to be assembled be encoded using the TerraGo GeoRegistration encoding that was published as an OGC best practice in 2008. The OGC best practice is the most widely distributed GeoRegistration encoding in terms of existing PDF libraries and workflows because GeoPDF was the only geospatial PDF available preceding the release of Acrobat 9.

• This option is useful if you know that all of the maps to be assembled were encoded using the OGC best practice and your users are running an older version of the GeoPDF Toolbar.

GeoPDF Toolbar 5+ (OGC Preferred)

• GeoPDF Toolbar 5+ (OGC Preferred) prefers that the maps to be assembled be encoded using the TerraGo GeoRegistration encoding method, but allows the assembly of maps that have been encoded using the ISO 32000 GeoRegistration encoding method.

• This option is useful if the maps to be assembled have been encoded using either encoding method and your users are running multiple versions of the GeoPDF Toolbar.

GeoPDF Toolbar 5+ (ISO Only)

• GeoPDF Toolbar 5+ (ISO Only) requires that the maps to be assembled be encoded using the ISO 32000 GeoRegistration encoding method.

• This option is useful if you know that all of the maps to be assembled were encoded using Adobe's encoding method and your users are running a later version of the GeoPDF Toolbar.

Note: Adobe implemented a different PDF GeoRegistration encoding when it released Acrobat 9 and submitted that method to ISO as a proposed extension to ISO 32000. Both OGC and ISO GeoRegistration methods encode the same information; however, more coordinate systems are supported using Adobe's GeoRegistration encoding. TerraGo software is capable of reading and writing both encoding methods.

Arranging the files

• Click the mover buttons to arrange the files as you want them ordered in the Layers tab of the assembled map.

• Click Remove to delete a file from the list of files to be assembled.

• Select a file and then click Modify to open the Layer Settings dialog box in which you can change the layer description, transparency percentage and the blend mode.

• You can also choose to ignore the map's neatline and create a transparency group for the layer, based on the transparency percentage you specify.

Assembling and saving the map

• Click Assemble to create the new map.

• To save your map as a GeoPDF file, from the File menu, click Save As.

• From the Save in list box, navigate to the folder in which you want to save the map.

• In the File name list box, type the name of the map.

• Click Save.

Adding layers to the map that is currently open

• Open the GeoPDF file to which you want to add layers.

• From the GeoPDF Composer Toolbar, click the Map Assembler tool.

• Check the Add Layers to the Active Map box.

• Click Browse to open the Select PDF Files to assemble dialog box.

• From the Look in list box, navigate to the location where the GeoPDF files or geospatially-aware PDF files that you want to assemble into a new map are located.

• Select the files for the layer assembly and then click Open.

• In the Default Layer Name group box, choose either File Name or Map Frame Name as the name to display in the layer properties.

• The disabled Make Compatible With list box defaults to the GeoRegistration encoding method you specified in the GeoRegistration Format Compatible With list box on the TerraGo Preferences dialog box. If you did not specify an encoding method, the default for the GeoRegistration Format Compatible With list box is GeoPDF Toolbar 3+ (OGC).

• Click the mover buttons to arrange the files as you want them ordered in the Layers tab of the assembled map.

• Click Remove to delete a file from the list of files to be assembled.

• Select a file and then click Modify to open the Layer Settings dialog box in which you can change the layer description, transparency percentage and the blend mode.

• You can also choose to ignore the map's neatline and create a transparency group for the layer, based on the transparency percentage you specify.

• Click Assemble to create the new map.

• From the File menu, click Save.

Assembling a map by drawing a polygon

Defining the map area

• Open the GeoPDF index map from which you want to assemble a new map. Note: The index map on which you draw the polygonmust contain links to GeoPDF files or geospatially-aware PDF files to successfully assemble a map.

• From the GeoPDF Composer Toolbar, click the Map Assembler tool.

• Click Draw, then click your map to create the starting point. A single-click inserts a vertex. A right-click removes the last segment.

• Continue clicking your map to create the area to measure.

• Double-click your map to automatically complete the polygon.

• In the Default Layer Name group box, choose either File Name or Map Frame Name as the name to display in the layer properties.
