The geobase is the spatial representation of the road network in the form of a filamentary network composed of lines called sections. The update operations are recorded in a log with the identifiers of the sections, the dates and types of the operations, and the version numbers. The geometry of the edges affected by the update operations is not recorded in the log and as a result **_this data set does not contain geospatial information_**. Only operations performed after **_25 October 2017_**, starting with version **_618_**, are included in the __Géobase - section management__ data set.

The geobase is a filamentary network of straight segments commonly called “sections”, which are generally digitized at the center of the street. A section is then a portion of road with homogeneous characteristics described mainly by the following attributes: an official and current toponym, address ranges and a reference to administrative boundaries (boroughs, municipal boundaries, neighborhoods as the case may be).

The geobase is the spatial representation of the road network in the form of a filamentary network composed of lines called sections. At the intersections of these sections or at their limits, points called __knots__ are placed, which, in special cases, have a specific type.

Geobase poles are a point representation of the left and right sides of segmented sections of the road network. They are related to the [double geobase] (/city-of-montreal/geobase-double) which presents the same information in linear form.

The double geobase is presented as a projection of the geobase's filamentary network that approximately simulates the boundaries of sidewalks and curbs. The [geobase poles] (/city-of-montreal/geobase-pole), a punctual representation of the left and right sides of segmented sections of the road network, are also available on the portal. The [Snow Planner API] (https://donnees.montreal.ca/ville-de-montreal/deneigement) refers to a static version of the double geobase data extracted at the beginning of the season. To monitor the changes made during the winter season, you can refer to the following data sets: [Geobase - section management] (https://donnees.montreal.ca/ville-de-montreal/geobase-gestion-troncon) and [Geobase - destroyed sections] (https://donnees.montreal.ca/ville-de-montreal/geobase-troncon-detruit).

The geobase is the spatial representation of the road network in the form of a filamentary network composed of lines called sections. A section represents a portion of road with homogeneous characteristics, including attributes such as official place names, address ranges, functional hierarchy classes, traffic directions, and other information. During the upgrade operations, some sections are destroyed, as the roads they represented were closed. Also, when sections need to be segmented or merged, the old sections are destroyed and new sections are created. This data set includes the destroyed sections that were part of the [Geobase - road network] data set (http://donnees.montreal.ca/dataset/geobase). Only sections destroyed after ** _October 25, 2017_ ** are included in this __Geobase - destroyed tracks__ data set.

GeoAI are buildings, hydrography, forests, and roads automatically extracted using Deep Learning models applied to a source dataset, typically aerial or satellite images. The primary aim of GeoAI is to increase Canada's availability of high-resolution foundational geospatial data for both spatial and temporal coverage.‌The infrastructure and expertise put in place by NRCan enables a rapid, efficient, and scalable data creation process through the use of leading-edge technology and Artificial Intelligence models. Published datasets for a given source can be revisited at a later date as more accurate models are developed and put into production. For now, only static files are available, but as the series develops, new products and services will be added.

The National Rail Network (NRWN) is a geometric and attributive description of the Canadian rail network.The NRWN product consists of the features classes: Track Segment, Railway Crossing, Railway Station, Marker Post, Junction and Railway Structure. Descriptive attributes include amongst others: Track Classification, Track Name, Track Operator, Track User, Track Owner, Subdivision Name, Junction Type, Crossing Type, Level of Crossing, Warning System, Transport Canada Identifier, Station Name, Station Type, Station User, Structure Type.

Notice - Replacement of the English and French Web services (WMS and ESRI REST) with a bilingual one.The NRN product is distributed in the form of thirteen provincial or territorial datasets and consists of two linear entities (Road Segment and Ferry Connection Segment) and three punctual entities (Junction, Blocked Passage, Toll Point) with which is associated a series of descriptive attributes such as, among others: First House Number, Last House Number, Street Name Body, Place Name, Functional Road Class, Pavement Status, Number Of Lanes, Structure Type, Route Number, Route Name, Exit Number. The development of the NRN was realized by means of individual meetings and national workshops with interested data providers from the federal, provincial, territorial and municipal governments. In 2005, the NRN edition 2.0 was alternately adopted by members from the Inter-Agency Committee on Geomatics (IACG) and the Canadian Council on Geomatics (CCOG). The NRN content largely conforms to the ISO 14825 from ISO/TC 204.

The National Hydro Network (NHN) focuses on providing a quality geometric description and a set of basic attributes describing Canada's inland surface waters. It provides geospatial digital data compliant with the NHN Standard such as lakes, reservoirs, watercourses (rivers and streams), canals, islands, drainage linear network, toponyms or geographical names, constructions and obstacles related to surface waters, etc. The best available federal and provincial data are used for its production, which is done jointly by the federal and interested provincial and territorial partners. The NHN is created from existing data at the 1:50 000 scale or better. The NHN data have a great potential for analysis, cartographic representation and display and will serve as base data in many applications. The NHN Work Unit Limits were created based on Water Survey of Canada Sub-Sub-Drainage Area.
