About Blom

Our history

Blom UK has recently reached a milestone and celebrated our 90th year. Whilst being known under many different names, and having produced a variety of services, the basics have always been the same… experienced staff producing innovative, technical and high quality products.

Aerofilms was founded by Francis Willis in 1919 and were the first ever commercial aerial photography company in the UK.  Simmons Mapping was founded by Derek Simmons in 1965 and specialised in traditional land survey. In 1997 Aerofilms and Simmons Mapping merged to become Simmons Aerofilms Ltd. This merger helped create a company that could provide both aerial photography and survey and mapping services.

In 2005 Simmons Aerofilms was taken over by Blom ASA and became Blom Aerofilms. Since 2009 the company has solely been known as Blom.

The Blom Group

Blom was founded by hydrographer Ole H Blom in 1954 and is now one of the European leaders of acquisition, processing, modelling and services based on geographical information.

What we do

Blom has a workforce of over 1,100 trained staff all excelling in their fields of expertise. Traditionally aerial photography and surveys were our core market. Back in 1919 in the UK Aerofilms staff were hanging out the side of planes with hand held cameras to capture Oblique and Vertical photographs of individual landmarks. The group now has over 18 aerial survey planes and leases four helicopters to transport our 23 large format camera and 10 LiDAR systems around the globe to produce high accuracy airborne surveys. These products are still part of our core services; however any successful company’s growth is based on innovating and creating new services. Blom is proud of the innovation that is embraced in our offices. We now move ahead into new markets and products  maintaining our strong reputation in the core aerial photography and mapping fields.
