Mackenzie Valley Air Photo Contours Data

Mackenzie Valley Air Photo Digital Orthotiles

Grid shift files for use with an NTv2 algorithm. The grid spacing is 30”. Supports transformations in New Brunswick between datums: 1. NAD27 and NAD83(CSRS); and 2. ATS77 and NAD83(CSRS).

The Yukon Digital Geology CD-ROMs present a variety of geoscience data sets in digital format on the geology of the Yukon Territory. They include syntheses of bedrock geology and glacial limits, compilations of geochronology, paleontology, mineral occurrences, oil and gas wells, and a compendium of aeromagnetic images. A subset of a public domain topographic data set (Digital Chart of the World, by ESRI, Inc.) is included for georeference purposes. For ease of use, data sets are divided geographically into 45 map tiles corresponding to the National Topographic System (NTS) 1:250,000 quadrangles. Data sets spanning the entire Yukon Territory are also included for use on sufficiently powerful computers and GIS software. Each theme for all of the 45 map tiles is presented in two projections. An Albers Equal Area projection, on disc 1, is provided to allow seamless integration of adjoining tiles throughout the Yukon. The complete data set is also provided on disc 2 in the UTM coordinate system, which is commonly used for accurately plotting data at the local scale (see Projections). Vector data files are also presented in several different file formats (ArcInfo coverages; Interchange (.e00), dBase (.dbf), shapefiles (.shp), and image data files are presented in band interleaved by line (.bil), and tagged image file format (*.tif) to allow easy importing of data into commercial GIS software. These CD-ROMs also include a limited edition of SurView, a viewing application for Microsoft Windows, developed at the Geological Survey of Canada and originally released as GSC Open File 2661. SurView runs directly off the CD-ROM. It can display, print, and query the *.shp and *.bil files. This provides an opportunity for those without specialized GIS software to delve into the realm of digital geoscience data and explore the Yukon Digital Geology databases on their own PC.

Data includes: * The Lake Superior watershed * The Lake Huron watershed * The Lake Erie watershed * The Lake Ontario watershed * The St. Lawrence River watershed

New geochemical data from re-analysis of archived stream sediment samples have been assessed using weighted sums modeling and catchment basin analysis as described in the methodology report that accompanies this map (YGS Open File 2015-10). Both commodity and pathfinder element abundances are evaluated to highlight areas that show geochemical responses consistent with a variety of base and precious-metal mineral deposit types. The results of modeling, completed using two approaches, are presented as a series of catchment maps and associated data files. This release is part of a regional assessment of stream sediment geochemistry that covers a large part of Yukon.

This set provides users of the Société de Transport de Montréal (STM) public transport with timetables, real-time bus positioning and, since version 2, data on the occupancy rate on board buses. *To access GTFS—Realtime and the i3 API, register on the [Developers] Portal (https://www.stm.info/fr/a-propos/developpeurs) *.

This digital product is a compilation of surficial geological data of the Halifax Metropolitan area which was defined by Dan Utting using a LiDAR derived bare-earth hillshade model. The LiDAR data was collected by PHB Lasermap, and provided by Halifax Regional Municipality. The data was used to create Open File Maps OFM ME 2011-001 to 2011-012, compiled by D. J. Utting, 2011. The digital product was created by Geoscience and Mines Branch staff at the Department of Energy and Mines. The digital product contains layers for geological features such as: age dates, drumlins, eskers, geological contacts, surficial geologic units, ice movement, moraines, meltwater, neatline, station locations, and large aggregate quarries.
