Mainly using embassy.org, staff updated the embassy list and used the DC master address repository to locate the points. Four embassies located in NY are not included in the list.

in OCTO



The Following steps were done to update the embassy's layer:

1. Cross referenced the existing embassy data to the list of embassys located in the District according to embassy.org identifying changes.
2. Deleted point locations of embassys that had moved.
3. Changed attributes for those embassies that did not move but had updated information.
4. Created a list of new embassy locations in excel.
5. Geocoded the list of new embassy's to the District's master address repository. 6. Merged the geocoded list of new embassys with the existing data to create an update embassy feature class.
