Description: This data represents the Human Disturbances Dataset for the North Slave Region, South Slave Region, Sahtu Administrative Region, and Inuvik Administrative Region (and/or Inuvialuit Settlement Region)using information from the Mackenzie Valley Land and Water Board, Wek'eezhii Land and Water Board, Gwich'in Land and Water Board, Sahtu Land and Water Board, Inuvialuit Water Board, and Nunavut Impact Review Board registries by Caslys Consulting Ltd. between 2000 and 2023. (Note this dataset extends across all of the NWT and into a portion of Nunavut to provide information across the Bathurst Caribou Range, which straddles the territorial boundary.).This was part of the Human Disturbance Mapping project for the GNWT, where a series of spatial datasets were created with the key objective to create an accurate and up-to-date human disturbance footprint that can be used to help make future land and water management decisions. These datasets were created based on existing baseline GIS data, aerial and satellite imagery, as well as permit records from registries with associated online archives..Modelling and other landscape GIS analyses that use this information may benefit from combining all point, line and polygon datasets into a single disturbance footprint that best represents the sum of all input files. It is recommended that this process be completed by first applying GIS buffer functions to point and line feature classes. This provides the advantages of having a more true representation of disturbance footprint with the ability to calculate spatially explicit functions, such as determining the area of the total disturbance. Using the ‘PointArea_Ha’ (Permit_Data_Points) and ‘LinearWidth_m’ (Permit_Data_Lines) fields respectively, users can calculate the buffer distance for each record in the point and line feature class files. The values in these fields do not represent the buffer distance itself, but can be used to calculate an appropriate buffer distance that can be added to an additional buffer-distance-field..Using the date fields and seasonal date fields, the user may develop queries that will allow human disturbance information to be displayed for a specific time period. Refer to Section 3.2 in the Human Disturbance Mapping Report (Caslys, 2015) which lists the fields that can be used to accomplish date-specific queries, as well as the Technical Guide - Selection by Date (Caslys, 2015) which outlines the query syntax..Along with the content created through this mapping project, several other GIS map layers should be used to create a comprehensive representation of the human disturbance footprint. Primarily, roads that have been previously mapped have not been re-captured under the scope of this project. Therefore, any modelling that is developed to map the human disturbance footprint should include other map layers managed by NWTCG. Refer to Section 3.1 in the Human Disturbance Mapping Report (Caslys, 2015) for a list of recommended map layers to be included in this process. As well, refer to the (NWT Cumulative Impact Monitoring Program) Inventory of Landscape Change Map Viewer to view a series of map layers that all contribute to the total development footprint.
