Migrate data to the Local Government Information Model

Summary

The Local Government Information Model (LGIM) is a schema from Esri that provides the architecture and framework to manage city and county data. This model is considered a starting point for users with city and county data, as it can be customized by adding additional fields, feature classes, and relationships.

Procedure

Refer to the instructions provided below for steps on creating the LGIM database, creating a staging database, and preparing data for use in the LGIM.

Note:
It is recommended that organizations only migrate one dataset or department at a time. The amount of time taken to resolve data preparation issues and field mapping of the current schema to a LGIM schema may cause down time.

A. Create a blank LGIM database to be used for staging

1. Download and install the LGIM schema.
2. Download and install the X-Ray for ArcCatalog tool.
3. Open ArcCatalog, and open the X-Ray panel.
4. Create a new empty database to be used as the destination database.
5. Import the Local Government schema. For steps to do this, refer to the following ArcGIS Help document, Local Government Information Model: Import Local Government schema.

B. Prepare data

6. Repeat Steps 3-5. Ensure all of the data is in the same coordinate system and projection. Otherwise, project or batch project all data to the projection of the staging database using the Project tool. If the data does not have a defined projection, use the Define Projection tool.
7. Import all data to the staging geodatabase as datasets. For more information, refer to the following ArcGIS Help document, ArcGIS Desktop: An overview of importing datasets.
8. Run the Check Geometry tool on all feature classes.
9. Run the Multipart to Singlepart tool on all feature classes.

   Note: 
   Multipart features are supported in LGIM; however, using complex data such as multipart features may affect the performance of the model.
   

C. Map the field and migrate the data

10. For each feature class, determine where existing fields are to be mapped in the LGIM. For more information, refer to the following ArcGIS Help document, ArcGIS Desktop: Using the field mapping control.
11. Append data or use the Object Loader wizard to load data from the current database to the LGIM database.
