Re: Integrated Survey Area No. 51, City of Langford, New Monuments

The coordinate control monument listing for the Langford Integrated Survey Area has been updated to include ten new coordinate control monuments recently installed to densify the network and has been published in an electronic format under the authority of section 13(5) of the Land Survey Act. In addition to the new monuments, one existing benchmark (GCM40469) has been upgraded such that it is now an integrated monument and one existing monument has been shifted by 9mm (GCM488486) due to better integration. The updated listings are available for viewing or download from the Surveyor General Division section of the LTSA website under Integrated Survey Area Program. This web page displays a table of all Integrated Survey Areas in numerical order. The ISA number provides a link to the respective coordinate control monument listing.

An electronic map of the location and extent of all Integrated Survey Areas is published in the ParcelMap BC Search for Land Surveyors view on myLTSA under the authority of section 13(1) of the Land Survey Act. ParcelMap BC shows the location and designation of the coordinate control monuments on the Survey Features >> Survey Control layer and the boundary of the integrated survey areas on the Survey Features >> Integrated Survey Areas layer.

A user may also link to the MASCOT Survey Control Database to obtain control monument sketches and detailed coordinate information and revision history. To invoke this function within ParcelMap BC, turn on the Survey Control layer to see the location of all monuments.

Click on the desired monument location; in the Search Results pane on the right side of the screen the monument should be listed by GCM number and when hovered over there is a link to ‘Search MASCOT’ which will bring up a new page with the GCM number pre-entered for a search in MASCOT.

Legal surveys within the Langford Integrated Survey Area must be integrated according to Part 5 of the General Survey Instruction Rules.

Yours sincerely,
