The Roads database includes an inventory of road assets (roadways, blocks, intersections, sidewalks, curbs) with a spatial representation and various attached information. Zone-type road assets represent regions located between other road assets and that are not part of the local or arterial road network. The areas are represented by polygons. Among the information associated with a zone-like object is the type of zone, etc. Related data is also available in separate sets on the portal: - [Road asset (complete database)] (/city-of-montreal/road-active) - [Roadway and intersection] (/city-of-montreal/voirie-causee-intersection) - [Sidewalk and island] (/city-of-montreal/voirie-trottoir-ilot) __Warnings__ - The data released on road assets are those in the possession of the City's geomatics team and are not necessarily up to date throughout the territory. - The data released on road assets is provided for information purposes only and should not be used for the purposes of designing or carrying out works, or for the location of assets. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Geometric and conventional representation of the rail system for planning purposes. This geospatial data is structured according to the following layers of information; - CARTO-IR-ACCESSORY: level crossing barrier & level pass lantern - CARTO-FER-DEBARCADERE: dock for the embarkation/disembarkation of goods or passengers - CARTO-FER-PONT: railway engineering structure making it possible to cross an obstacle - CARTO-FER-VOIE: railway These elements form part of the layers in the digital cartographic compilation.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

3D topographic representation of the territory in the form of a point cloud. LiDAR (Light Detection and Ranging) technology makes it possible to represent the Earth's surface topographically in three dimensions using a laser system mounted on board an aircraft. The very large number of 3D points recorded (up to 400,000 per second) makes it possible to obtain a multitude of details at the level of the ground and surface elements. LiDAR technology quickly, easily, and above all accurately provides the altitude of ground details and elements above ground, even in the presence of dense vegetation. The uses are: creation of a digital terrain model (MNT), creation of level curves, creation of level curves, volume calculation, planning, calculation of tree heights, mapping of building roofs, 3D modeling of cities, etc. Source: XEOS Imaging Inc. **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Extent of plant cover formed by trees on the territory of the City of Montreal. The canopy is the summation of the projections to the ground of each tree crown or group of trees over 3 meters in height. It is represented on surfaces, even for isolated trees. No cells are used in this layer.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

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. Related data sets: - [Geobase - road network] (http://donnees.montreal.ca/dataset/geobase) - [Geobase double - street sides of the road network] (http://donnees.montreal.ca/dataset/geobase-double) - [Geobase - poles] (http://donnees.montreal.ca/dataset/geobase-pole) - [Geobase - section management] (http://donnees.montreal.ca/dataset/geobase-gestion-troncon) - [Geobase - nodes] (http://donnees.montreal.ca/dataset/geobase-noeud) __Warnings__ - The data released (Geobase - destroyed sections) must be used in accordance with the City of Montreal's open data policy and license. - The data disseminated (Géobase - destroyed sections) are those that are in our possession and are not necessarily up to date throughout the country. - The data disseminated (Géobase - destroyed sections) is provided for information purposes only and should not be used for the purposes of designing or carrying out the works, nor for the purpose of locating assets. - The City of Montreal and the Geomatics Division cannot be held responsible for the inaccuracies or inaccuracies of the data disseminated (Geobase - destroyed sections). **This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Geometric and conventional representation of airport facilities for planning purposes. The geospatial “aerodrome” data is structured according to the following layers of information: - CARTO-VOI-AERODROME-TRACK: A defined surface on earth intended to be used, in whole or in part, for the arrival, departure and maneuvers of aircraft. - CARTO-VOI-AERODROME-PARKING: A furnished area, off the airfield runway, intended for the parking of a certain number of aircraft.
