Chapter C4 - Surveys Offshore

Figure C4-1 Areas of Justisdiction

This figure depicts a black and white map of Canada showing the provincial boundaries, the arctic region, water bodies and drainage lines, and areas of jurisdiction for the management of petroleum resources, with a legend that describes the jurisdictional areas. Shades of colour from light gray to black represent the various areas of jurisdiction which include: "Minister of Indian Affairs and Northern Development", "Minister of Natural Resources Canada", "Canada - Newfoundland Offshore Petroleum Board", and "Canada - Nova Scotia Offshore Petroleum Board". A thick black line separates the northern region from the south. Return to Chapter C4

Chapter D1 - Official Surveys

Figure 1 - CLS 77 Post

Figure 1 shows a diagram of the side and top views of a CLS 77 Post. The post is 91.4 cm long, 1.9 cm diameter at the top, and tapers to a conical shape at the bottom. It is of a "No. 6 Reinforcing State Rod" type, and is encased towards the top in an aluminum casting. Return to Chapter D1 Figure 1

Figure 2 - CLS Standard Rock Post

Top view and side view of a CLS Standard Rock Post. The top view is a disk with a diametre of 8 centimetres and with the inscription 'Arpentage des terres du Canada Lands Surveys', the year and a crown inscribed around the edge of the disk. The side view is a rod of 7 centimetres in length, of 1.9 centimetres in diameter topped with a flat disk of 8 centimetres of diametre and of 0.6 centimetre in thickness. Return to Chapter D1 Figure 2

Figure 3 - Positioning of Pits and Mound

There are four squares representing pits measuring each 0.7 by 0.7 metres each positioned in a cross shape with a small circle the middle of the shape. The circle in the middle of the shape is located 1.65 metres from the closest edges of all four squares. A bigger square representing a mound measuring 1.5 by 1.5 metres is located on a boundary line between two pits, with a distance of 3 meters between the circle and the middle of the mount. There is a space of 1 metre between the edges of the mound and the closest edges of the two adjacent pits. Return to Chapter D1 Figure 3

Chapter E3 - Guidelines for the Preparation of Plans

Schedule E3-2 Table 1

The table contains two columns of symbols under "placed" and "found" as follows:

  • DLS or CLS standard post: An unfilled donut shaped figure, made up of two concentric circles, under placed; and same figure with a filled internal circle under found.
  • DLS or CLS standard rock post: An unfilled donut shaped figure, made up of two concentric circles, under placed; and same figure with a filled internal circle under found. The phrase "P. Rock" is placed to the right side of each symbol.
  • Old pattern iron posts: A single unfilled circle with the letter "I" placed to right side of it is used for placed, and a filled circle with the same letter is used for found.
  • CLS 69 posts: An unfilled circle with the text "69" to the right side is used for placed, and a filled circle with the same text is used for found.
  • CLS 77 posts: An unfilled octagon with the text "77" to the right side is used for placed, and a filled octagon with the same text is used for found.
  • Control Survey Markers: A unfilled triangle with a subscribing circle is used for placed, and a filled triangle with a subscribing circle is used for found.

Chapter E4 - Accuracy Standard for Legal Surveys

Figure E4-1

This is a diagram showing a solid line joining a point labelled "A." in the south-west corner to another point labelled "B." in the north-east corner. Both points are represented by a filled circle. On the left side, a dashed line runs vertically from point "A." to a point labelled "1." Which is represented by an unfilled circle. Another dashed line runs from point "1.", crossing the solid line A-B at a point labelled "C." with an unfilled circle, and ends at point "2." to the bottom right (below point "B."), also with an unfilled circle. A dashed line that runs from point "2." and another dashed line from point "B." meet at a point labelled "3." to the right side, also with an unfilled circle. Return to Chapter E4 Figure E4-1

Figure E4-2 - Closed Traverse

This shows a closed figure described by six points represented by unfilled circles and labelled "1." through "6." clockwise. Dashed lines join point "1." in the north-west corner to point "2." south-easterly, then to point "3." easterly, then to point "4.", southerly, then north-westerly to point "5.", then south-westerly to point "6." and finally, northerly to point "1.".

Chapter E5 - Digital Spatial File Specifications

Figure 1

Figure showing three contiguous rectangles representing three parcels with a narrow band superposed diagonally across the lots representing an easement. The line type of the lines illustrating the parcels is solid, and line type of the lines illustrating of the easement is dashed. Return to Chapter E5 Figure 1

Figure 2

Figure showing two drawings where the first one being two non-intersecting lines, and the second one being two intersecting lines. Return to Chapter E5 Figure 2

Figure 3

Figure showing two drawings where the first one being two crossing lines, and the second one being two intersecting lines. Return to Chapter E5 Figure 3

Figure 4

Figure showing two drawings where the first one being two lines joined at 90 degrees and a third line crossing the first two lines near their intersection point, the second one being two lines joined at 90 degrees and a third line crossing the first two lines at their intersection point. Return to Chapter E5 Figure 4

Figure 5

Figure showing two drawings where the first one being two parcel corners separated by a small space, the second being two parcel corners joined in one point. Return to Chapter E5 Figure 5

Figure 6

Figure showing two drawings where the first one being one horizontal line joined by a vertical line in its middle with one small black square over the junction of the lines and a small black square on the horizontal line located on the left of the first square, the second one being one horizontal line joined by a vertical line in its middle with one small black square over the junction of the lines Return to Chapter E5 Figure 6
