Quebec Hydrographic Network Geobase (GRHQ)

The Geobase of the Quebec Hydrographic Network (GRHQ) is the common frame of reference for hydrography in Quebec. It is a detailed hydrographic network that can support numerous applications in land use planning, the environment and civil security.

The GRHQ is produced in partnership with the Ministry of the Environment, the Fight against Climate Change, Wildlife and Parks (MELCCFP) and the Ministry of Natural Resources and Forests (MRNF) using the following data:

* The hydrographic classes from the Quebec Topographic Database (BDTQ) at the scale of 1/20,000 of the MERN for the south of the province;
* CanVec's hydrographic classes at the scale of 1/50,000 from Natural Resources Canada for the north;
* The continuity segments of the MELCCFP network;
* The hydrographic division units of the MELCCFP;
* The official toponyms from the TOPOS database of the Toponymy Commission. 

The main components are:

_Geometric network_

* Points
 * Point components of the geometric network (hydrographic junctions).
* Lines
 * Linear geometric network representing the continuity of flow across all types of hydrographic entities (linear and surface).

_Thematic Information_

* Points
 * Class of context entities represented in point form that enrich the thematic content of the various hydrographic components.
* Lines
 * Class of context entities represented in linear form that enrich the thematic content of the various hydrographic components.
 * Class of linear entities representing the shores of hydrographic surfaces.
* Surfaces
 * Class of context entities represented in surface form that enrich the thematic content of the various hydrographic components.
 * Class of surface entities representing hydrographic surfaces. 
 
_Management Units_

* Surfaces

CPTAQ inclusions and exclusions

The inclusions and exclusions come from applications for authorization submitted under the Act respecting the protection of land and agricultural activities (LPTAA L.R.Q., c. P-41.1) relating to the inclusion of lots in the agricultural zone or to the exclusion of lots in the agricultural zone.
o The file of inclusions and exclusions represents polygons resulting from decisions of the Commission that modify the boundaries of the agricultural zone. An inclusion adds an area to the agricultural area while an exclusion removes it. The boundaries of the agricultural zone are then the result of the addition of these decisions.
o Decisions are spread over time and there may be a partial or total superposition of an area resulting from inclusion and exclusion. In these cases, consider the result from the highest file number, which is the final result.

· Source of inclusions and exclusions
o The reference documents that served as the basis for the digitization of decisions are: the basis for
topographic data of Quebec (BDTQ) at a scale of 1:20,000, the cadastral compilation at the scale
1:20,000, the Quebec Cadastre, orthophotos and various plans.
· Warnings and limitations
o All the inclusions and exclusions folders are also contained in the file of
decisions. However, a decision leading to an inclusion or exclusion will not take effect until
when it was registered with the Registrar's Office. It is only at this time
that the decision will appear in the inclusions and exclusions file. Several months may
elapsing between a decision and its registration. If the conditions are not met within the deadline
If the decision is given, it will lapse.
o With the progress of cadastral renovation, more and more territories in agricultural areas are
dependent on the new cadastre. The renovated cadastre has the advantage of being more precise and better
structured as the cadastral compilation. On the other hand, you should know that several decisions leading to
an inclusion or exclusion has been rendered and mapped on the cadastral compilation. By
Therefore, in order to limit the risks of misinterpretation, refer to the text of the
decision as well as the attached plan if necessary to validate the positioning if necessary.

 Goal: To have an overview of CPTAQ decisions and to facilitate the processing of authorization applications.**This third party metadata element was translated using an automated translation tool (Amazon Translate).**

Aggregate roadway and intersection (Road Assets Database)

The Roads database includes an inventory of road assets (roadways, blocks, intersections, sidewalks, curbs) with a spatial representation and various attached information.

Aggregate pavement assets represent carriageways located in the public domain and that are part of the local or arterial road network. Aggregate pavements are represented by polygons that are aggregated by type of use.

Among the information associated with a pavement object is the date of construction, the date of resurfacing, the date of survey, the materials of the pavement, the type of foundation, the presence of a bicycle lane, the use, etc.

Intersecting road assets represent road crossings located in public areas that are part of the local or arterial road network. Intersections are represented by polygons that are cut according to the number of traffic axes.

Information associated with an intersecting object includes the construction date, resurfacing date, survey date, intersection materials, foundation type, presence of bike lanes, etc.

Data is also available in separate sets on the portal to support several uses:

- [Road asset (complete database)] (/city-of-montreal/road-active)
- [Sidewalk and island] (/city-of-montreal/voirie-trottoir-ilot)
- [Off-road zone] (/city-of-montreal/voirie-zone) 

__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).**

Road friendliness for cyclists

Data on the friendliness of roads for cyclists reflect as accurately as possible the conditions encountered on roads managed by the Ministry of Transport and Sustainable Mobility (MTMD).
 
The levels of usability are determined according to the following three criteria: the posted speed is low; the shoulders are wide and paved; the flow of vehicles, especially trucks, is limited. Based on these criteria, roads are classified as follows:

- Friendly road (generally in accordance with bike lane standards)

- Moderately friendly road (presenting constraints to the safety and comfort of cyclists)

- Unfriendly road (presenting significant constraints for the safety of cyclists)

- Road forbidden to cyclists (highway, for example)

- Gravel road (no usability index is calculated for gravel roads)


Note: Specific conditions that are not safe for cyclists can occur along a segment of the road, even if it is described as “friendly.”

Permafrost in Nunavik

**Permafrost** is any soil or rock whose temperature has remained below 0°C for years. In the extreme north of Quebec, it is omnipresent and very thick. At its boreal margin, further south, it appears in the landscape in the form of isolated thin plates, whose thickness is generally less than 10 m. Permafrost contains ice in various forms, whose origin is closely linked to the sedimentary characteristics and drainage conditions of the land.

The mapping of permafrost conditions for Nunavik (territory located north of the 55th parallel), carried out by the Center for Nordic Studies at Laval University, was done by applying a simple model called TTOP (Temperature at the Top Of Permafrost) for the period from 2000 to 2016. The results of the model are presented in the form of a raster file that illustrates the distribution of continuous, discontinuous, and sporadic permafrost, as well as isolated islands.

Under the effect of global warming or poorly adapted human activities, permafrost heats up or even thaws, which leads to settlements and ground movements affecting ecosystems as well as infrastructures. Thus, the susceptibility of the territory to thermokarstic subsidence was evaluated for the same territory taking into account the ice content and the temperature at the top of the permafrost. A matrix file (raster) of the susceptibility of the territory to ground subsidence associated with permafrost thaw presents three susceptibility classes (high, moderate, and low) as well as areas generally without permafrost.

Historical forest maps

__The link: *Access the data directory* is available in the section*Dataset Description Sheets; Additional Information*__.


Formerly, forest maps were produced by the Land Survey Department of the Ministry of Lands and Forests. Some of these maps dating **from 1924 to 1946** still exist and are treasured at the National Archives of Quebec. 

The information they contain makes it possible to locate and characterize forest areas in certain regions of Quebec. Color codes were then assigned for each of the following classes: young forests, old forests, burned, logged, rocky, savannas, and colonization.

Northern Quebec surface deposit

Deposit is the layer of loose material that covers rock. It may have been established during the retreat of the glacier at the end of the last glaciation or by other processes associated with erosion and sedimentation. The nature of the loose deposit is evaluated based on the shape of the land, its position on the slope, the texture of the soil, or other indicators. Surface deposit maps make it possible to distinguish the main categories of surface deposits, to know their nature, thickness and distribution on Quebec territory. 

The map of **surface deposits in the North** is a component of an extensive inventory carried out to meet knowledge acquisition needs as part of the economic, social and environmental development project “Plan Nord”. This inventory was carried out between 2010 and 2013. The mapping of surface deposits was carried out using a new approach based on remote sensing techniques. The interpretation was carried out by geomorphologists using RapidEye anaglyph (3D) satellite images with high spatial resolution (5 m). Ground and air control points allowed the validation of the interpreted information.

Mapping is available throughout the country north of the 53rd parallel, which represents an area of approximately 680,000 km2. The minimum mapping area is 100 ha.

Geotechnical investigation site

The term “geotechnical investigation site” refers to locations where geotechnical (surveys and instrumentation) and geophysical data are available. This data includes:

Geotechnical investigation sites (site_inv_geotech_p): Geotechnical surveys produced by or for the Ministry from the 1990s, from the active database of the Directorate of Geotechnics and Geology (DGG). Data is added as it is validated.
This file is accompanied by a Stratigraphic Characteristics table (site_inv_geotech _STRATI.csv). This contains stratigraphic information for the majority of sites and can be linked to the location file using the “NO_UNIQUE” primary key.

BDG geotechnical investigation sites (site_inv_geotech_bdg_p): Geotechnical drilling and drilling from an “inactive” database entrusted to the DGG by the Ministry of Natural Resources and Wildlife (MRNF), since the mid-1980s. These are drilling and survey data compiled by the MRNF in the 70s and 80s for “predictive” or “geotechnical soil suitability” mapping campaigns.
As it is an inactive database (not evolving), there are no updates to be expected.

Temporary sample plot from the fifth inventory

The temporary sample plot is a circular sample unit that covers an area of 400 m2. For each tree, we observe and measure the species, diameter, sunlight, and floor in relation to other trees, as well as the defoliation and the quality of the stems of deciduous trees and certain pines. In addition, the age and height of three trees are determined. Finally, a survey of the station and the vegetation of the undergrowth is carried out, and the characteristics of the soil are noted. Plot data also includes information about the location of the plots and the sampling plan. 

These data are acquired as part of the **fifth ecoforest inventory of southern Québec**. They are used in particular to produce forest compilation results used to feed the calculation of forest opportunities in public forests in Quebec. They can also be useful in the development of private forests. 

The establishment of these plots began in 2017. 

This database covers part of the territory south of the 52nd parallel of Quebec's public and private forest.
