SLC Associates -Geomatic Engineers image

Our mission is to provide geospatial data of the highest quality for any purpose. This has traditionally been for mapping purposes but nowadays is biased towards aeronautical data.


LC Associates have now been operating for over 30 years. 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 also changed in 2010 and now says ‘SLC Geomatic Solutions’, a trading name that is becoming more familiar.

Our specialist aeronautical Surveyors have now successfully carried out over 260 WGS-84 aerodrome surveys in 34 different countries around the World. We have also developed specialist software to handles electronic terrain and obstacle data (eTOD) and analyses aerodrome obstructions. To date GDMS is available online as well as in a Desktop version and is in use at over 60 locations worldwide.

Our specialist aeronautical Surveyors have successfully carried out over 260 WGS-84 aerodrome surveys and continue to provide aeronautical grade positional data worldwide.
