Re-Geocoding Exposure Data


Geocodes express the physical position of a location, that is, the latitude (north positive) and longitude (east positive) of the location. AIR strongly recommends that you geocode all exposure data before running analyses. Geocoding involves scanning each location record in a contract and then, using the best available address information, computing the geocode and updating the location record.

Exposure data is automatically geocoded during the import process. The geocoding log contain a summary of match results; the geocode match level indicates the accuracy of the latitude and longitude assigned to each location. You can re-geocode all the exposure data in an exposure view, a single contract, and a single location. Re-geocoding writes over user-supplied geocodes only if the Geocoding Settings default is to overwrite existing latitudes and longitudes.

You can monitor the progress of the geocoding in the Activity Monitor, where the activity name is "Geocode Exposure View" and the activity type is "Geocode".

For more information, see Using Geocoding in Touchstone, which is available on the AIR Client Portal.

To re-geocode exposure data:

1.      In the navigation pane, under Project Data, click Exposure Views.

2.      Highlight the exposure view that you want to geocode again. The Management tools, including Geocode, become available.

3.      Click Geocode.

4.      To re-geocode a contract:

a.      Open the Contract List.

b.      Highlight the contract that you want to geocode again.

c.       Click Geocode.

5.      To re-geocode a location:

a.      Open the Contract List.

b.      Open the Contract Details for the contract containing the location that you want to geocode again.

c.       In the Contract Details pane, highlight the location that you want to geocode and then check the information in the Address area of the Locations grid—the location must have one of the following pairs, City and State OR Latitude and Longitude, OR a Postal Code. (You can use the Column Chooser to select Address columns that may not appear in the default grid, such as the Latitude and Longitude columns.)

d.      In the Management area of the Contract ribbon, click Geocode.

  You can also check the Address information in the Location record, which you access by clicking the Location ID in the Contract Details pane. To geocode the location, you must select the Exposure Views tab and then, in the Management area of the Contract ribbon, click Geocode.
