Published Parameter

Published Parameters for map.apps ETL specific input methods

In map.apps ETL, the different input methods require workspaces that are configured with certain Published Parameters:

Input method Published Parameter Usage

Input method	Published Parameter	Usage
File Upload	`mapapps_etl_files`	The parameter provides the path to all uploaded files, which can be used to read data within the workspace (e.g. FeatureReader, Reader).
Map extent selection	`mapapps_etl_extent mapapps_etl_line mapapps_etl_point mapapps_etl_polygon`	The parameter provides a bounding box / line / point / polygon as a EsriJSON String, which is usually used as a clipping geometry. Use a GeometryReplacer to create a FME Geometry from the string.
Features from the map	`mapapps_etl_features`	The parameter provides the path to a file containing EsriJSON features from the map. The features can be read using a EsriJSON Reader.

File Upload

mapapps_etl_files

The parameter provides the path to all uploaded files, which can be used to read data within the workspace (e.g. FeatureReader, Reader).

Map extent selection

mapapps_etl_extent mapapps_etl_line mapapps_etl_point mapapps_etl_polygon

The parameter provides a bounding box / line / point / polygon as a EsriJSON String, which is usually used as a clipping geometry.

Use a GeometryReplacer to create a FME Geometry from the string.

Features from the map

mapapps_etl_features

The parameter provides the path to a file containing EsriJSON features from the map. The features can be read using a EsriJSON Reader.

Additional map.apps ETL parameters

The following parameters are optionally and will be filled automatically if existing:

Published Parameter Usage Requirement

Published Parameter	Usage	Requirement
`opt_requesteremail`	If used, the chosen FME process will be executed asynchronously. Possible results will be sent to the user via email.	Is only used if you fill it in the parameter dialog or by choosing Use the email address of the currently logged in map.apps user for asynchronous processes. FME Server Notifications have to be configured.
`mapapps_etl_featuretypes`	Provides the names of selected feature types of the uploaded files.	Is used in the File Upload if an analyze workspace is configured. The result of the analyze workspace allows a deselection of feature types to process.
`mapapps_etl_user`	Provides the name of the map.apps user	Transfer the currently logged in map.apps user needs to be activated.
`mapapps_etl_epsg`	Provides the currently used EPSG code of the map.

opt_requesteremail

If used, the chosen FME process will be executed asynchronously. Possible results will be sent to the user via email.

Is only used if you fill it in the parameter dialog or by choosing Use the email address of the currently logged in map.apps user for asynchronous processes.

FME Server Notifications have to be configured.

mapapps_etl_featuretypes

Provides the names of selected feature types of the uploaded files.

Is used in the File Upload if an analyze workspace is configured. The result of the analyze workspace allows a deselection of feature types to process.

mapapps_etl_user

Provides the name of the map.apps user

Transfer the currently logged in map.apps user needs to be activated.

mapapps_etl_epsg

Provides the currently used EPSG code of the map.

Geometry Parameter:

The Published Parameter type Geometry is available since FME 2020. The different geometry types (point, line, area) are available as map.apps ETL Parameters and allow users to draw the desired geometry on the map. Attention: Geometry Published Parameters will provide a GeoJSON (not EsriJsON!) String.
