Some 20 Hotwire consultants from the agency's British, German, Spanish and Italian offices will be working on the retained consumer and corporate account.
Blom gathers geographical information using a fleet of 33 planes and four helicopters, as well as laser equipment. With more than 1,000 employees across 23 countries in Europe, it is the largest European provider of mapping information but is virtually unknown to the general public.
Blom is looking to expand into the commercial satellite navigation systems market and has hired Hotwire to increase awareness among consumers.
The agency will target consumer publications, national media and navigation trade titles.
Blom takes photos at 45- degree angles, which - unlike satellite photography - provides a view of the front of buildings.
In 2006, Microsoft signed an agreement with Blom to use its photographs for Windows Local Live. Blom has also developed a navigation application for the iPhone.
Blom's services and software are also used by governments across the world.
