<DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Establish elevations for a network of monuments called benchmarks. A benchmark is a relatively permanent material object, natural or artificial, bearing a marked point whose elevation above or below an adopted datum is known. Vertical datums for referencing benchmark elevations are based on mean sea level. The basic vertical control for topographic mapping of the benchmarks or other points of known elevation established throughout a project, also termed basic control or level control. This data is all within the limits of the York Region Boundary and most were established approximately 20 years ago. Most are still considered accurate but it is suggested that they should be checked agianst other benchmarks to make sure.</SPAN></P><P><SPAN>The vertical datum is:</SPAN><SPAN STYLE="font-size:16pt">CGVD 1928 revised 1978</SPAN><SPAN STYLE="font-weight:bold;font-size:16pt">.</SPAN></P></DIV></DIV></DIV>
To show vertical elevations for a project through topographic surveys. Benchmarks are physical objects in the field that a surveyor can put their level or prism on to check elevation. Users of the benchmarks will be land surveyors, developers and local municipalities. The vertical datum is CGVD 1928 revised 1978.

Transportation Services - Roads requested that owner information be removed from the Full_Desc field. In order to keep a copy of owner information in the data a new field FULL_DESC_OLD was added and where an owner name was present the field information was copied from FULL_DESC into FULL_DESC_OLD. Transportation Services - Roads also requested that when data is pushed to SDW the following fields need to be removed.

Unscheduled Update Transportation Services requested the removal of 2 Vertical Benchmarks 2 Region benchmarks are destined for destruction. The benchmarks are on the foundations of the Wootten Way elevated tank (formerly called the Markham elevated tank) at 77 Wootten Way North, and the Sharon elevated tank at 97 Howard Avenue in Sharon.

As part of the regular Maintenance Schedule, Transportation Services, Infrastructure Management was contacted for updates. It was determined that no new information was available at this time.
2016-02-16T00:00:00
Data transfered to Transportation Asset Management for editing purposes. Data remodelled including removing old metadata fields and replacing with TAM metadata fields. Core fields left untouched to ensure continuity.
Three locations with 0 elevation had elevations added. M3-007 updated, no issues.24 & 44-27 updated with review elevation from 1978. May be some error in this update for those 2 locations (24 & 44-27).
One location with 0 elevation, 39035, has no paper copy to indicate elevation and will not be updated at this time.
