  • A population ecumene is the area of inhabited lands or settled areas generally delimited by a minimum population density. Two population data sets from the 2016 Census of Population were used to build two specialized ecumene maps. The census division ecumene was built from dissemination area population density data and the census subdivision ecumene was built from the dissemination block population density data. For information on census divisions, census subdivisions, dissemination areas, and dissemination blocks consult the Statistics Canada’s 2016 Illustrated Glossary (see below under Data Resources). Areas included in the ecumene (for either the census division or census subdivision) are areas where the population density is greater than or equal to 0.4 persons per square kilometre or about 1 person per square mile. In some areas to capture more population within the ecumene the criteria was extended to 0.2 persons per square kilometre. The ecumene areas were generalized in certain regions either to enhance the size of some isolated ecumene areas or to remove small internal uninhabited areas within the ecumene. Either of these ecumene resources can be used as an “ecumene” map overlay to differentiate the sparsely populated areas from the ecumene in conjunction with the appropriate census geography or other small-scale and large-scale maps.

  • Get data on forest fires, compiled annually for the National Forestry Database [The National Forestry Database]( includes national forest data and forest management statistics to seve as a credible, accurate and reliable source of information on forest management and its impact on the forest resource. Forest fire data is grouped into eight categories, which are further broken down by geographic location. These include: * number of fires by cause class and response category * area burned by cause class and response category * number of fires by month and response category * area burned by month and response category * number of fires by fire size class and response category * area burned by fire size class and response category * area burned by productivity class, stocking class, maturity class and response category * other fire statistics, such as property losses

  • The Geomatics Division archives contain more than 22,000 aerial photographs. The oldest dates back to 1930, but they are usually located between 1950 and 2003. The set provides a link to an interactive mapping allowing the download of multi-year aerial photographs held by the City for the purposes of basic mapping production. Images are available throughout the island of Montreal or partially depending on the years and scales of the aerial photographs. An aerial photograph is a photograph taken from the air. Normally, these are taken vertically, on board an aircraft, using a highly accurate shooting device. NOTE1: The Geomatics Division's collection is distinct from that of the Archives de Montréal. NOTE 2: The City disseminates the photographs in its possession. However, in the event that a claiman has claims in this regard, he or she is invited to submit them to the City. NOTE 3: Note that for archival images from paper media, the City generally does not hold the original slides. Refer to the index for details. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • The intended use of this data is to assist the public and ministry staff to locate licenced dairy plants.

  • Survey for Physella wright - the hotwater physa, at Liard River Hotsprings Provincial Park, August 2006.

  • During the period of 1987 to 1994, Robin J. LeBrasseur and N. Brent Hargreaves lead a juvenile salmon predation research project in Alberni Inlet and Barkley Sound BC. This dataset contains the research survey catch data and individual fish examinations data.

  • The Plains, Northern, Foothills Boundary feature class contains polygon features representing Department of Energy Regional Boundaries for the Province of Alberta.

  • This GIS dataset depicts the surficial geology of the NTS map area 83P Northeast (line features). The data are created in ArcInfo format and output for public distribution in Arc export (E00) and shapefile formats.

  • Published by the Ministry of Forests, Lands, Natural Resource Operations and Rural Development - Forest Analysis and Inventory Geospatial forest inventory dataset updated for depletions, such as harvesting, and projected annually for growth. Sample attributes in this dataset include: age, species, volume, height. The Vegetation Resources Inventory (VRI) spatial datasets describe both where a vegetation resource (ie timber volume, tree species) is located and how much of a given resource is within an inventory unit.

  • The Phase 1 (Broad Scale) Forest Inventory was initiated in 1949 and completed by 1956. The Phase 1 (Broad Scale) Forest Inventory included all publicly owned forested lands in the province except Indian lands, national parks, and an area known as the Rocky Mountains Forest Reserve. The Phase 1 (Broad Scale) Forest Inventory was used to define lands suitable for agriculture, to determine timber harvest levels and plan forest protection and timber and industrial development. Through aerial photo interpretation, land was classified as productive, potentially productive, or non-productive. On productive forest land, homogeneous groups of trees were classified by "cover types". Cover types included crown density, height and tree species. Burned, harvested or cultivated land was identified as potentially productive. Non-productive lands included areas with organic soils, barren rock and lakes. No ages or site classes are associated with the polygons. The minimum polygon size was 65 ha. These maps are not available as geo-referenced rectified images or GIS-ready data.
