Base waterbody polygon arcs are feature type, source and capture date attributed arcs that make up the boundaries of base waterbody polygons in the Base Features Hydrography geospatial dataset. These arcs were collected from conversion processes of 1:20 000, 1:50 000 and AVI Provincial mapping datasets and 1:50 000 National Topographic Data Base (NTDB).

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 1:50 000 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.

A claim is a parcel of land located or granted for hard rock mining. A claim also includes any ditches or water rights used for mining the claim, and all other things belonging to or used in the working of the claim for mining purposes. A claim is a rectangular plot of ground that does not exceed 1,500' X 1,500'. All angles of a claim must be right angles, except in cases where a boundary line of a previously located claim is adopted as common to both locations.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .

Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three numbers (e.g. 098). 1:250,000 mapsheets are identified by a combination of numbers, and letters ranging from A through P (e.g. 098C). Sixteen smaller segments (1 to 16) form blocks used for 1:50,000 mapping (e.g. 098C03).

A placer claim is a parcel of land located or granted for placer mining. A claim also includes any ditches or water rights used for mining the claim and all other things belonging to or used in the working of the claim for mining purposes. A placer claim is a rectangular plot of ground. All angles of a claim must be right angles, except in the case where a boundary line of a previously located claim is adopted as common to both locations. The length of a regular placer claim from post one to post two is 500 feet along a baseline. Co-discovery claims must not exceed 1250 feet each and single discovery claims must not exceed 1500 feet.Distributed from the [GeoYukon](https://yukon.ca/geoyukon) digital map data collection by [Yukon government](https://yukon.ca/maps) .

Stream Centreline Network derived from 1:50,000 scale mapping. Each stream channel is represented by one or more line segments. Based on the 1:50,000 scale Canadian National Topographic Series of Maps.

When the tenure data differs from the actual post locations on the ground, we use adjoining parcels to show that the area has no open ground.Distributed from [GeoYukon](https://yukon.ca/geoyukon) by the [Government of Yukon](https://yukon.ca/maps) .
