Export Profiles Supporting Various Projections

Before configuring a list of projections for the WebOffice extract server tool, check the coordinate systems (CS) of your data and your WebOffice 10.9 SP1 project (main map service data frame) to see which of the following possible combinations you are dealing with:

1.CS of data = CS of the WebOffice 10.9 SP1 project = CS of export

2.CS of data = CS of the WebOffice 10.9 SP1 project ≠ CS of export

3.CS of data ≠ CS of the WebOffice 10.9 SP1 project = CS of export

4.CS of data = CS of export ≠ CS of the WebOffice 10.9 SP1 project

5.CS of data ≠ CS of the WebOffice 10.9 SP1 project ≠ CS of export

 

Pay attention when it is necessary to define geographic transformations. Depending on the component, the geographic transformations has to be configured at different places as shown in the figure below. Find detailed descriptions in the examples below.

1.Data, WebOffice 10.9 SP1 Project and Export use the same Coordinate System

Export

If this is the case, there is no need to configure a List of Projections in the WebOffice extract server tool.

 

2.Data and WebOffice 10.9 SP1 Project use the same Coordinate System but Export should be available for other Projections

With this scenario, it is necessary to configure a Projection element in the WebOffice extract server tool.

If projecting to the Export coordinate system requires a geographic transformation, be sure to provide it two times:

As a parameter in the Projection element. Otherwise the projection will not be available in the Export Projection drop-down list.

As a task inside the export configuration file (has to be configured for each task). Otherwise, the projection is done without transformation. See chapter GeoTransformationCodes for details about the task in the export configuration file.

3.The Export will use the same Coordinate System as the WebOffice 10.9 SP1 Project, however the Data originally use a different Coordinate System

However, if projecting from the Data to the Export coordinate system requires a geographic transformation, be sure to provide it as a task inside the export configuration file (has to be configured for each task). Otherwise, the projection is done without transformation. See chapter GeoTransformationCodes for details about the task in the export configuration file.

 

4.The Export will use the same Coordinate System as the data, however the WebOffice 10.9 SP1 Project uses a different Coordinate System

With this scenario, it is necessary to configure a Projection element in the WebOffice extract server tool that defines the Export coordinate system.

If projecting from the WebOffice 10.9 SP1 Project to the Export coordinate system requires a geographic transformation, be sure to provide as a parameter in the Projection element. Otherwise the projection will not be available in the Export Projection drop-down list.

If projecting from the Data to the Export coordinate system requires a geographic transformation, be aware that you will need to add the geographic transformation as a task in the configuration file (has to be configured for each task). Otherwise, the projection is done without transformation. See chapter GeoTransformationCodes for details about the task in the export configuration file.

 

With the example coordinate systems defined above this would mean the following geographic transformation settings are required.

Web Mercator (Auxiliary Sphere) (WebOffice 10.9 SP1 Project coordinate system) to ETRS 1989 Austria Lambert (Export coordinate system) needs the geographic transformation with the EPSG code 1149 (ETRS_1989_To_WGS_1984) in the Projection element in the WebOffice extract server tool

MGI Austria GK East (Data coordinate system) to ETRS 1989 Austria Lambert (Export coordinate system) needs the geographic transformation with the EPSG code 1785 (MGI_To_ETRS_1989_3) in the export configuration file.
