SLC Associates -Geomatic Engineers image

Our mission is to provide aeronautical data of the highest quality.

SLC Associates have been operating since 1987. The original partnership was incorporated in January 2001 as Geomatic Solutions Ltd but continues to trade under the more familiar names of SLC Associates or SLC Geomatic Solutions. The corporate logo was redesigned in 2010 and now says ‘SLC Geomatic Solutions’, a trading name that is becoming more familiar.

Our specialist aeronautical surveyors have successfully carried out over 300 WGS-84 aerodrome surveys, in 34 different countries around the world.

Our software, Geospatial Data Management System (GDMS), which is used to handle electronic terrain and obstacle data (eTOD) and analyse aerodrome onstacles, has become the market leader for aerodrome safeguarding with over 400 registered users.

GDMS is now available online for day to day safeguarding without the need for any software, as well as the main desktop version which is in use at over 60 locations worldwide.
