Description:
Abstract: This dataset is produced for the Government of Alberta and is available to the general public. Note that the distribution contact is different for the general public than for Government of Alberta ministries. Please consult the Distribution Information of this metadata for the appropriate contact to acquire this dataset. The National Topographic System of Canada (NTS) is a national mapping reference grid defined by Natural Resources Canada (NRCan) that is based on degrees of latitude and longitude. Starting at the Prime Meridian and at the equator, the 1:250 000 grid is formed by intersecting every degree of the meridians with every two degrees of parallels. Each polygon in the grid is designated with a two digit number and a single letter (Example 83H). The province of Alberta is covered by 45 complete and 17 partially complete 1:250 000 NTS blocks.
Purpose: For orientation and reference.
Supplemental Information: Historically, maps were provided based on the NTS grid. Medium scale maps used the 1:250 000 NTS grid (1 cm equals 2.5 km).

Other Citation Details: The National Topographic System of Canada (NTS) is a national mapping reference grid defined by Natural Resources Canada (NRCan) that is based on degrees of latitude and longitude. Starting at the Prime Meridian and at the equator, the 1:50 000 grid is formed by intersecting every 1/4 degree of the meridians with every 1/2 degrees of parallels. It can also true that the standard 1:250 000 NTS block is broken down into 16 1:50 000 blocks that a numbered south to north alternating east to west then west to east from one to 16. Each polygon in the grid is designated with a two digit number; a single letter and two additional numbers (Example 83H08). The province of Alberta is covered by 670 complete and 131 partially complete 1:50 000 NTS blocks.

Other Citation Details: The National Topographic System of Canada (NTS) is a national mapping reference grid defined by Natural Resources Canada (NRCan) that is based on degrees of latitude and longitude. Starting at the Prime Meridian and at the Equator, the 1:20 000 grid is formed by intersecting every 1/8 degree of the meridians with every 1/4 degrees of parallels. It is also true that the standard 1:50 000 NTS block is broken down into 4 1:20 000 blocks that are labelled by quadrant. Each polygon in the grid is designated with a two digit number; a single letter; two additional numbers and a two letter quadrant value (Example 83H08NE). The 1:20 000 NTS grid was developed to support the Provincial Digital Base Mapping Project and is not part of the formal NRCan NTS program. The province of Alberta is covered by 2838 complete and 269 partially complete 1:20 000 NTS blocks.

Lineage:
Process Step:
Process Description: Creation of the NTS grid was performed using an ArcInfo 7.2 commands that created a regular grid based on input. Based on the ratio one degree of latitude by two degrees of longitude the grid for the entire province was created. Each polygon was then attributed with its 1:250 000 NTS designation.

Process Step:
Process Description: Densification of the grid arcs. As the ESRI projection commands only calculate positions at the node and vertex of a line, it was necessary to introduce a series of vertices into each arc so that the NTS grid line would better approximate a projected line of latitude.
