Data performance tips

Proper tuning of the database and the implementation of attribute and spatial indexes during the data loading operation will enhance the performance of any application. This is especially true for ArcGIS Roads and Highways because of the extensive data processing steps involved.

For optimal performance from mapping events in Roads and Highways, make sure that your database has the appropriate indexes created. You can use the Add Attribute Index geoprocessing tool to create indexes.

Table nameMulticolumn attribute index fields

LRS Network feature class

  • RouteID (the concatenated routeID in the network feature class)
  • From Date
  • To Date
  • Route Name (if configured)

Calibration Point feature class

  • Route ID
  • Network ID
  • From Date
  • To Date

Centerline feature class

  • Centerline ID

Centerline Sequence table

  • Route ID
  • Network ID
  • From Date
  • To Date
  • Centerline ID

Lookup table

  • Key Field
  • (if lookup table is configured with this field)

Event feature class

  • Event ID
  • Route ID
  • To Route ID (if configured)
  • From Date, To Date

Intersection feature class

Примечание:
  • Route ID
  • From Date
  • To Date

Since the centerline, calibration point, network, and event feature classes are stored in a geodatabase, spatial indexes are automatically created and maintained for you. In some circumstances, recalculating a spatial index may improve performance, as described in Modify a spatial index.
