Verisk Synergy Studio location information schemes
Verisk Synergy Studio supports one or more location information schemes for supplying non-street-level location data for exposures in each modeled country.
Specifying location information
Before importing exposure data into Verisk Synergy Studio, you must specify location information for each of your exposures.
Supplying non-street-level location data
Verisk Synergy Studio uses its area information database to match location data that you input at a specific geocode match level.

Verisk Synergy Studio location information schemes
- Verisk Synergy Studio location information schemes
  Verisk Synergy Studio supports one or more location information schemes for supplying non-street-level location data for exposures in each modeled country.
  - Specifying location information
    Before importing exposure data into Verisk Synergy Studio, you must specify location information for each of your exposures.
    - Expected location information types
      When supplying location information, you can specify either location names or the corresponding location codes.
    - Importance of specifying codes
      While your location data may include both location names and location codes, Verisk recommends specifying location codes whenever possible.
    - Supplying non-street-level location data
      Verisk Synergy Studio uses its area information database to match location data that you input at a specific geocode match level.
      - Verisk Synergy Studio geocode match levels for non-street-level address data
        Supported geocode match levels for non-street-level address data.
    - Supplying U.S. street-level address data
      Verisk Synergy Studio now uses the Verisk US GeoPin Geocoder as the default solution for U.S. street address geocoding.
    - Disaggregation
      Verisk Synergy Studio handles disaggregation as part of loss analyses, not as part of import and geocoding processes.
    - Premium International Geocoding
      Premium International Geocoding is an optional, licensed feature for high-resolution, address/street level geocoding.
    - Supplying geocodes
      If you choose to include and retain (that is, preserve) specific geocodes (and the corresponding country codes) for exposures, Verisk Synergy Studio uses these geocodes directly.
    - Geocoding with country and city data
      For certain countries and cities, Verisk Synergy Studio can geocode locations that were imported with only country and city data.
    - Resolution precedence
      Verisk Synergy Studio geocodes at highest resolution possible with available data for a country and model.
  - Remapping
    Verisk Synergy Studio may remap a set of location data that you have entered to another set of location data in either of the following circumstances.
  - Verisk Synergy Studio geocoding for specific countries
    When you supply location information for an exposure in the following countries, Verisk Synergy Studio uses a specific geocoding procedure.
  - Troubleshooting location information input
    Potential causes of geocoding errors.
Country-specific location information schemes

Supplying non-street-level location data

Verisk Synergy Studio uses its area information database to match location data that you input at a specific geocode match level.

This match occurs when you supply country, CRESTA, area, subarea, subarea 2, and/or postal information. The match level determines which geocode centroid Verisk Synergy Studio assigns to each set of location information that you supply. The non-street level geocode centroids are derived from the Verisk Industry Exposure Database and boundary data. The stated geocode match level can help you to understand why Verisk Synergy Studio has assigned a particular centroid geocode to a set of location data that you have entered.

Note: In some cases, the minimum resolution requirements of a model make it necessary for Verisk Synergy Studio to augment (that is, "forward fill" and/or "back fill") the location data that you have supplied for exposures in order to increase the resolution level of the corresponding location data and to support the modeling requirements.

Verisk Synergy Studio stores the geocode match level in the GeoMatchLevelCode field for each location record in the tLocation table within the VeriskExposure database.

The centroid for a given area can be generated using any of the following methods, depending on the country, resolution, available data, and model requirements:

Exposure-weighted centroids: Verisk Synergy Studio uses the Verisk Industry Exposure Database for a given country and the related building exposure distributions adjust the centroid based on the geographic distribution of the exposures in the Industry Exposure Database.
Population-weighted centroids: Verisk Synergy Studio adjusts the centroid based on the geographic distribution of census populations.
Geographic centroids: Verisk Synergy Studio uses boundary data to generate a geographic centroid for a given area.
