Total Soil Moisture (mm)
Total soil moisture is the modelled amount of plant available water (mm) in the root zone of the soil. The value given is the amount calculated to be present on the modeled day of the product.Values are computed using the Versatile Soil Moisture Budget (VSMB)
Percent of Normal Soil Moisture
Percent of normal soil moisture is the modelled amount of plant available water (mm) in the root zone of the soil, divided by the average amount that has historically been available on that day. This value is intended to provide users with a representation of conditions above or below normal as a percentage.Values are computed using the Versatile Soil Moisture Budget (VSMB)
Difference from Normal Soil Moisture (mm)
Difference from normal soil moisture is the modelled amount of plant available water (mm) in the root zone of the soil, minus the average amount that has historically been available on that day. This value is intended to provide users with a representation of conditions above or below normal and by the amount of water (mm).Values are computed using the Versatile Soil Moisture Budget (VSMB)
Versatile Soil Moisture Budget
The Versatile Soil Moisture Budget (VSMB) is a soil water budget model that is continuous and deterministic in nature and was developed by AAFC. It is based on the premise that the water available for plant growth is gained by precipitation or irrigation, and lost through evapotranspiration and runoff as well as lateral and deep drainage. The daily net loss or gain is added or subtracted from the water already present in the rooting zone. Water is withdrawn simultaneously, but at different rates, from different soil depths, depending on the potential evapotranspiration, the stage of crop development, the water release characteristics of each soil layer and the available water.
Crop Health Indices
These products represent crop health indices derived from the Versatile Soil Moisture Budget (VSMB) model using crop specific coefficients and station based precipitation and temperature measurements to simulate crop growth. The VSMB model simulates soil moisture dynamics and water stress conditions based on water availability in the soil profile and simulated evapotranspiration during the crop growing season. Crop phenological stages, which are related to crop water use, are determined by a biometeorlogical time scale model (Robertson, 1968) for cool season crops (wheat, barley etc.) and a Crop Heat Unit (Brown and Bootsma, 1993) algorithm for warm season crops (corn and soybean etc.).
Manitoba Road Network 2018
Highway Planning and Design's 2018 Manitoba Road Network.The 2018 Manitoba Road Network was created by Manitoba Infrastructure, Highway Engineering, Highway Planning and Design (HPD). The department’s linear referencing system (LRS) uses Control Sections as a linear referencing method (LRM). The LRM is the digital representation of the Highway Network in Manitoba. The features indicate highway number and highway identity. This data was corrected using 1:60,000 digital ortho aerial photography dated from 1991-1998. Linear features have been updated on a yearly basis using GPS data, CAD files and 50cm imagery from 2007-2014, and is considered accurate to two-to-seven metres. Please note that this feature layer primarily contains only the roads that Manitoba Infrastructure is responsible for, i.e. Provincial Trunk Highways, Provincial Roads and Access Roads. However, you may also see Earth Roads (under construction) or Other roads (such as those passing through national parks and are federal responsibility).Fields included (Alias (Field Name): Field description.) OBJECTID (OBJECTID): Sequential, unique whole numbers are automatically generated. SHAPE (SHAPE): A field to hold geometry information. ID (ID): Unique Identifier generated by Oracle. Control Section ID (CS_ID): Non unique identifier linking segment to its respective control section. Road Number Signed (ROAD_NO_SIGNED): The road number. Note though, that in the case of co-routes, the lower highway number appears. This is a text field and differs from ROAD_NO only where there are city routes, for example 1A. Road Location (ROAD_LOCATION): Access Road locations. Road Description (DESCRIPTION): A text description of the start and end locations of each segment. Control Section Key (CS_KEY): An information rich key containing Region (two digits), Road Number (three digits), Section number (three digits), the Road Type (one character), and direction of travel (one character). MI Region (REGION_NO): The Manitoba Infrastructure region the segment is in. Regions 1-5. Road Number (ROAD_NO): The road number. Note co-routes will have the lesser highway number. Section Number (SECTION_NO): The control section's section number. Start Kilometre (KM) (START_KM): The beginning of the Control Section (always zero). End Kilometre (KM) (END_KM): The number of kilometres to the end of the Control Section. Length Kilometres (KM) (LENGTH_KM): End Kilometre minus the Start Kilometre. Road Type (ROAD_TYPE): The road type, i.e. PTHs, PRs, and Access Roads (Earth roads under construction may also be included). Road Direction (ROAD_DIRECTION): A = ahead direction on a divided highway (i.e. following the digitizing direction), B = Back direction on a divided Highway (i.e. against the digitizing direction, and U= an undivided highway. Road Identity (ROAD_IDENTITY): Road identity i.e. Provincial Road, Earth Road, Access Road and Other Road. National Highway Classification (NATIONAL_HIGHWAY_CLASS): The national highway classification standard. Start Date (START_DATE): The date the segment was created in the database. Inventory Year (INVENTORY_YEAR): The year the road segment was opened to the public.
WSA - Stream Routes (50,000)
Stream routes. Each stream channel is represented by a single line. Derived from the Stream Centreline Network Spatial layer and based on the 1:50,000 scale Canadian National Topographic Series of Maps.
Polling Division Boundaries - Canada 2021
The digital Polling Division boundary files provided are made available from Elections Canada. The data contains the digital federal electoral districts under the Representation Order of 2013.
Ontario Hydro Network - Shoreline
The Ontario Hydro Network (OHN) is a provincial medium scale originating from data with regional scales of 1: 10,000 in Southern Ontario, 1: 20,000 in Northern Ontario and 1: 50,000 in the Far North. The shoreline is taken from the OHN - Waterbody data class. This data is used for cartographic purposes and web mapping services. This product requires the use of geographic information system (GIS) software.

National Hydro Network - NHN - GeoBase Series
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.
