Data Loader

About the Geographic Information System (GIS) Data Loader

The GIS Data Loader allows geospatial data associated with existing entities to be delivered to the GIS module (Maps) in GE Digital APM for further development, analysis, or implementation. Customers will be able to load data from other external systems into the GIS module via the Excel workbook.

About the GIS Data Loader Requirements

To use the GIS Data Loaders, your organization must have completed fully the deployment of the Maps module, with populated Family and Entity IDs.

Mapping

The GIS Data Loader populates geospatial data in the MI_ENTY_GEO_DATA table by mapping specified cells in the Excel workbook to the Entity Key field in GE Digital APM. The data loader populates the data in the following order:

ENTITY_KEY
ENTITY_ID
FAMILY_ID + ID_FIELD + ID

Note: The column positions in the spreadsheet should not be moved and the captions should not be changed.

Note: If data is not provided, the cell should be left empty.

About the GIS Data Loader Data Model

The following data model illustrates the records that the Data Loader supports.

GIS Data Loader Data Model

Note: In the diagram, GIS Location refers to the name of a database table. You can relate each GIS Location to an Entity of any family in GE Digital APM. Geometry represents the actual data for GIS Location. The Has Entity and Has Geometry are not the relationships defined in GE Digital APM. They are the relationships in an internal database and the purpose is same as the relationships between families.

About the GIS Data Loader General Loading Strategy

The imported data must load in a specific sequence to successfully populate fields, create records, and link data to the predecessor and successor records.

Best Practices

When importing data using the GIS Data Loader, you must use the following best practices:

To populate a record, use the ENTITY_KEY.
To search for an ENTITY_KEY, use the ENTITY_ID value.
To search for an ENTITY_KEY if ENTITY_ID is not provided, use the FAMILY_ID, ID_FIELD, and ID values together.
To create a new record, the referenced Entity Key should not have a corresponding record in the target table and provide the geospatial data.
To update a record, the referenced Entity Key should have a corresponding record in the target table, and to update new information, provide the new geospatial data.
To delete an existing record, the Entity Key referenced should have corresponding record in the target table, and do not provide the geospatial data (the cell should be empty).
Geospatial data in the GEOD_DATA column should conform to the geometry spatial data type.
All columns in the worksheets must be formatted as Text or Entity Key. Entity Keys should be formatted as Numbers.

Load Sequence

When importing data using the data loader workbook, you must use the following workflow:

Download the data loader workbook provided by GE Digital
Identify the data requirements for exporting the data into the data loader workbook.
Extract data from legacy applications to populate the data loader workbook.
Provide batch numbers in the Batch worksheet and in the first column of the remaining worksheets in the data loader workbook.
Import data into GE Digital APM.
Monitor the status of the data load, and verify the results in the log.
Conduct tests in GE Digital APM to ensure that the imported data loaded accurately.

For each row in the data loader workbook, the GIS Data Loader creates a new record in GE Digital APM. However, if records have already been created and you import the data, the existing records will be updated.

About the GIS Data Loader Workbook Layout and Use

In order to import data using the GIS Data Loader, GE Digital APM provides an Excel workbook, Geographic Information System (GIS).xlsx, which supports baseline GIS in GE Digital APM. This workbook must be used to perform the data load.

The following table lists the worksheets that are included in the GIS Data Loader workbook.


Worksheet	Description
GIS	The only worksheet used by the GIS Data Loader. It is used to load geospatial data for existing entities.

The following table lists the fields in the workbook:

GIS Worksheet


Field Caption	Field ID	Data Type (Length)	Comments
Batch ID	BATCH_ID	Character (50)	This is the Batch ID field.
Entity Key	ENTITY_KEY	Numeric	This is the Entity Key field.
Entity ID	ENTITY_ID	Character (255)	This is the Entity ID field.
Family ID	FAMILY_ID	Character (50)	This is the Family ID field.
Family ID Field	ID_FIELD	Character (50)	This is the ID Field name for the specified Family.
ID	ID	Character (255)	The is the ID field.
Geometry	GEOD_DATA	Character (4000)	This is the Spatial Data Field.

About the GIS Data Loader Load Verification

About This Task

After loading data, you must perform the following steps in GE Digital APM to ensure the integrity and accuracy of the data imported from the data loader workbook:

Review the details of the import job. These details will indicate if any errors occured during the data load. The log helps you identify any records that are not loaded.
Run a query to view a Geospatial data uploaded. You can use the baseline Map Query that is stored in the folder \\Tools\Maps\Baseline Map Query as a reference.
