Description: The data was originally drafted onto hard-copy 1:250,000 NTS map sheets and then was digitized by Mutli-imaging into Autocad drawing files in 1995. All original digital data was received 13th of November, 1995 in Autocad DXF files. The data was converted to ARC/INFO coverage format.All theme layers were digitized by map sheet. They were separated into the individual theme layers and merged together. Some data was missing so non-linear data was digitized from the hard copy maps into the Roots digitizing system and then converted to ARC/INFO coverages. If the data were straight lines, lat/long coordinates were used to create a line file. All missing data was then merged with the original coverages. All polygons were closed and centroids added and then cleaned to establish topology.Changes have been made to individual layers as the Regulations have changed. The name has changed to reflect the year of the changes. The individual theme layer metadata will record any updates. THe have been no updates to the Mackenzie Bison Sanctuary since the Regulations have been passed.The data was initially created as coverages and had limited distribution. In June 2001, it was decided that most users of this data did not need to know the origin of the line work. It was only required in case the location of a line is ever questioned so a secondary set of coverages were created in which the lines were simplified. This makes the data easier to use. E00 and shapefiles have been created using the 'simplified data' and all will have a simlar naming structure. ie original file BDRLIC96distribution BRDRL96DE00 file BRDRL96Dshapefile BRDRL96DBecause one of the original reasons that the digital layers were created was to support the Wildlife Act and Regulations, and as the linework used to outline each polygon was either digitized, or came from other sources and at varying times it was decided that a record was needed of the origin of each line segment that formed the boundary of each polygon.To record the information about each line segment, two attributes, SOURCE and DATE were added to each layer linework attributes.The first attribute, SOURCE is the source of the linework. Each value in the attribute field is described as followsNTS250 Data were mapped and then digitized from 1:250,000 NTS sheets. The original data was digitized by John Alexander of Multi-imaging, the DATE 11/13/95 was attached to all John Alexander's work as this was when it was received by NWTC RS, any missing data was digitized by Gerren Saskiw.LEGIS Lat/Longs from the legislation, ARC GENERATE was used to create coverages (XLINE*), which were projected to the Lambert projection and then the lines extracted and added to the appropriate coverages1:4MILLION An approximate boundary between Greenland and Canada derived from a 1:4 million scale map of Canada (polar bear and wildlife management units only) 12 mi buff Canada has a 12 mile territorial sea boundary which was generated using the ARC BUFFER command and land boundaries from the NSDB hydrography layer (barren-ground caribo and wildlife management units only)SMOOTH The boundaries of the Canada-Greenland border and the 12 mile sea boundary did require some manual 'smoothing' to reflect the actual respective boundary line (ie. eliminating bays and adjusting the boundary between Ellesmere Island and Greenland (spliting the distance)FMSMITH Changes to the Forest Management Zones layer that have been created by Forest Management in Fort Smith.The second attribute, DATE is the approximate date the data was received and entered into the databaseNOTE: These linework attributes are not included in the distribution version. If there is a need to know the source of the original linework, contact the NWTCG to obtain a copy of the original file.The following attributes may be present in each attribute file. Each attributes is prefaced with 'xx' which is a two character abbreviation of the layer name:xxAREA is the minimum attribute which is the management area identifierxNAME is the name of an areaxxSTATUS is the status of the area ie National Park or National Park Preserve
