  • The administrative dividing layers offered at the scales of 1/20 000 and 1/100 000 allow the location of boundaries for the following components: * Boroughs and agglomerations; * Municipalities, Unorganized Territories and Aboriginal Territories; * Administrative Regions, Metropolitan Communities, and MRC; * Border , the interprovincial borders, and the Quebec—Newfoundland and Labrador border. For the 1/100 000 scale version, the initial 1/20 000 scale cut data are adjusted to the corresponding planimetric components at the 1/100 000 scale. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • This hypsometric layer represents the relief of Quebec territory at a scale of 1:20 ,000. Level curves are extracted from [1:20 ,000 scale topographic maps] (https://www.donneesquebec.ca/recherche/fr/dataset/cartes-topographiques-a-l-echelle-de-1-20-000). They are usually at an equidistance of ten metres and, in some cases, they can vary between eight and twenty metres. This data layer includes level curves as lines and dimension points as points and text. Each file covers an area of approximately 250 km2. The web service is produced using topographic data at a scale of 1:20 ,000 to the south and Natural Resources Canada (CanVEC product) mapping data at a scale of 1:50 ,000 to the north. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • These digital terrain models (DEM) provide a regional numerical representation of Quebec relief from altimetry (altitude) and planimetric (rectangular or geographic) data. They are the result of a collaboration between the Ministère de l'Énergie et des Ressources naturelles (MERN) and Natural Resources Canada (NRCan) on the Agreement for the Production of an Up-to-date Digital Mapping of Northern Quebec and the creation of the “National Hydro Network (NHN)” product for the territory of Quebec. When integrated into a geographic information system, these models allow the implementation of multiple types of spatial analysis such as natural hazards, landscape analysis, infrastructure implementation, etc. The DEMs are obtained through hypsometric and hydrographic data processing using thehydro consistency consisting of interpolating elevation values by ensuring a connected drainage network and a fair representation of ridges and streams. The NHN oriented filament is used to mark lakes and control the altimeter descent of rivers. The final product is a quality portrait of the relief at a scale of 1:50 ,000. Terrains provide elevation values based on a grid resolution of 0.324 arc seconds in geographic coordinates, which corresponds to a resolution of about 10 meters in the field. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • The Geographic and Administrative Database is available at the scale of 1:1 million (BDGA1M) and 1:5 million (BDGA5M). It provides a small scale geographical and administrative base for the entire territory of Quebec. The data come from an automatic generalization of the vectors of a database at a scale of 1:250 ,000, and from a geometric and thematic purification. Data from territories outside Quebec should be used and considered with some reservation given the date of update and the classifications used. The administrative limits also derive from the generalization of data at a scale of 1:250 ,000 on the major hydrographic axes. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • The Global Navigation Satellite System (GNSS) includes all satellite navigation systems. It allows you to know your location, anywhere in the territory. GNSS theoretical specifications estimate the accuracy of the position obtained from a receiver at approximately 15 metres in planimetry and 25 metres in altimetry. By combining the data with another receiver placed on a known geodetic point, the accuracy of the position obtained can vary from a few centimetres to a few metres, depending on the type of receiver used. In order to increase accuracy, the Government of Quebec records data continuously through a network of 18 GNSS stations. These stations are located on obstructed geodetic points and collect data from GPS and GLONASS constellations. Some of these stations receive signals from the constellation Galileo. This data is available in standard RINEX exchange format (Receiver Independent Exchange Format version 2.11). This format is recognized by most GNSS data processing software. You must ensure that the coordinates in your processing software are in accordance with the document “[Contact Information for GNSS Capture Stations] (ftp://ftp.mrn.gouv.qc.ca/Public/Gps/CoordonneesGNSS.htm)». This document lists the stations that receive Galileo signals. The data can be accessed on the [ftp server] (ftp://ftp.mrn.gouv.qc.ca/Public/GPS) of the MERN or using the [Interactive Map] (https://geodesie.portailcartographique.gouv.qc.ca/) of the geodetic network. It should be noted that only data from the last 365 days are retained. __Havre-Saint-Pierre: Out of service since 2018-04-12__ # #GNSS in real time by cellular telephony The government also offers GNSS data via cellular phone that allows for centimeter positioning work in real time. Users of geo-referenced data can, with a single GNSS receiver (GPS, GPS+GLONASS or GPS+Glonass+Galileo) equipped with a mobile phone modem, track or implement any physical detail with an accuracy of a few centimetres into the NAD 83 Reference System (CSIS). The signal that contains this data is accessible to everyone. The range depends on telephone coverage, ionospheric conditions and, above all, the instruments used. For more information on the use of GNSS in real time, see [Guidelines for GNSS Surveys in RTK/RTN Mode in Canada] (http://publications.gc.ca/site/fra/9.822883/publication.html). # #Détails Techniques The transmission of GNSS data and NAD 83 (CSIS) coordinates of the station is via cellular telephony from an IP address over the Internet. Each station transmits its data in one of the following two formats: CMR+ or RTCM V3.1. Stations that receive Galileo signals transmit them in RTCM V3.2 format. __Havre-Saint-Pierre: Out of service since 2018-04-12__ The table at [next link] (ftp://ftp.mrn.gouv.qc.ca/Public/Gps/AdresseIP_Temps_reel.htm) gives for each city the IP address of CMR+ and RTCM formats (V3.1 or V3.2) as well as the antenna model. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

  • The product of the land rights layer (leases) contains the centroid or, in some cases, the outline of leases granted by the Government of Quebec, or granted by the RCMs and cities that have signed an agreement to delegate land management and the management of sand and gravel exploitation on lands in the domain of the Crown. The main components are: * Personal use (e.g., principal residence, cottage, summary forest shelter) * Commercial purpose (e.g., outfitting, tourist site, fish farming, sawmill) * Public purpose (e.g., telecommunications) * Municipal purpose (recreational or sporting activities) * Community purpose (shelter, shelter, lodge, trail) According to in the case, the data sources are: * GPS seizures * Aerial photographs* Survey surveys **This third party metadata element was translated using an automated translation tool (Amazon Translate).**
