The Atlas of Canada Base Maps provide coverage of the entire Canadian landmass. Data elements are feature coded and structurally clean. Base map components are available in five scales and a number of data exchange formats. The 1:2 million and 1:7.5 million scales are the primary bases for all Atlas products. The 1:30 million scale data have been generalized from the two larger scales. The data set covers: drainage (coastlines, rivers, lakes), boundaries (federal, provincial, district, dividing lines), transportation (primary and secondary highways, selected ferry routes, rail networks), populated places, national parks. Atlas information is two-dimensional layered vector data.

This data set is an index identifying Ontario Base Map (OBM) map tiles and digital vector data available for each tile. Eastern and Southern Ontario is covered at a scale of 1:10,000 and Northern Ontario is covered at a scale of 1:20,000.

Ontario Base Maps (OBM) are a series of maps created and updated by the Ontario Ministry of Natural Resources between 1977 and 2000. The MNR extracted the 33 layers from their NAD83 NRVIS dataset to create the NAD83 digital OBM sheets and vector data packages. The data provided may not be spatially defined upon download and may need to be defined using GIS (e.g. NAD 83 UTM Zone 18).

Many geometrical schemes – or map projections – are used to represent the curved surface of the Earth on map sheets.Canada uses the Universal Transverse Mercator (UTM) system. It is called transverse because the strips run north-south rather than east-west along the equator.This data class shows a 1 km x 1 km UTM NAD83 grid that is a standard reference index for Ontario.It includes:Military Grid ReferenceFire Base Map identifierFire Base Map BlockAtlas identifierAdditional DocumentationUTM Grid - User Guide (Word)UTM 1KM Grid - Data Description (PDF)UTM 1KM Grid - Documentation (Word)StatusCompleted: production of the data has been completedMaintenance and Update FrequencyAs needed: data is updated as deemed necessaryContactOffice of the Surveyor General, landtenuremapping@ontario.ca

A Township is a land subdivision in Ontario. This information was captured through the Ontario Base Mapping Program, is maintained by the Ministry of Natural Resources and distributed through Geospatial Ontario (GEO) Warehouse. The spatial accuracy for some of the townships was improved through the Ontario Parcel, Township Realignment and Township Improvement projects. Improvements may include: * road allowance widths * spatial changes to better represent where the township boundaries are located * more consistent concession names Materials used to improve the location of township lines may include: * township Improvement plots * survey information i.e. retracements * original township plans * surveys notes * the physical features e.g. fence lines in the corporate editing environment * water bodies * GPS Ontario Road Network geometry This product requires the use of geographic information system (GIS) software.

This index identifies project areas on provincial highways where aerial photography and photogrammetric mapping has been collected.

Geographic Information System (GIS) data with the following mapping layers from the Greenbelt Plan:

• outer boundaries
• protected countryside and urban river valley designations
• specialty crop areas (Niagara tender fruit, grape area and Holland Marsh)
• settlement areas (towns, villages and hamlets)
• river valley connections.

The data also contains associated policy designation mapping.

Zoom in on the map above and click your area of interest or use the Tile Index linked below to determine which package(s) you require for download. The Digital Elevation Models (DEM) are 2-m resolution raster elevation products that were generated from the Ontario Classified Point Cloud (Imagery-Derived) data. The point clouds were created via a pixel-autocorrelation process from the stereo aerial photography of the Land Information Ontario (LIO) imagery program. It is important to note that the DEM does not represent a full ‘bare-earth’ elevation surface. There are areas where there are very few points classified as Ground and interpolation has occurred across the resulting voids. Points classified as Ground have not been assessed for accuracy to determine if they represent true ground features. Some features are still raised above ground surface, such as larger buildings, larger forest stands and other raised features.

The GOES-R PLT Southern Ontario Lightning Mapping Array (LMA) dataset consists of total lightning data measured from the Southern Ontario LMA (SOLMA) network during the GOES-R Post Launch Test (PLT) airborne science field campaign. The GOES-R PLT airborne science field campaign took place in support of the post-launch product validation of the Advanced Baseline Imager (ABI) and the Geostationary Lightning Mapper (GLM). The LMA measures the arrival time of radiation from a lightning discharge at multiple stations and locates the sources of radiation to produce a three-dimensional map of total lightning activity. These data files are available in compressed ASCII files and are available from April 1, 2017 through June 1, 2017.

Technical information Using cached imagery and topographic data, the application provides a fast, seamless display at pre-defined scales. The caches are updated annually.

Bathymetry is the measurement of water depth in lakes. From the 1940s to the 1990s, the Ministry of Natural Resources and Forestry produced bathymetry maps for over 11,000 lakes across Ontario. The data can be used by the general public and GIS specialists for: * climate change modelling * fish monitoring and other ecological applications * hydrologic cycle modelling * recreational fishing maps * watershed-based water budgeting The maps were created using simple methods to determine lake depths. They were meant for resource management purposes only. Little effort was made to identify shoals and other hazards when creating these bathymetric maps. Since this data was collected, many constructed and naturally occurring events could mean that the depth information is now inaccurate, so these maps should not be used for navigational purposes. In many cases, these maps still represent the only authoritative source of bathymetry data for lakes in Ontario. Technical information These maps are being converted to digital GIS line data which can be found in the Bathymetry Line data class. The Bathymetry Index data class identifies if GIS vector lines have been created and the location of mapped lakes. The historic paper maps have been scanned into digital files. We will add new digital files to this dataset if they become available. The digital files have been grouped and packaged by regions into 13 compressed (zipped) files for download. Note: package 99 contains scanned maps where the location shown on the map could not be determined.

This is a georeferenced raster image of a printed paper map of the Bothwell, Ontario region (Sheet No. 040I12), published in 1994. It is the seventh edition in a series of maps, which show both natural and man-made features such as relief, spot heights, administrative boundaries, secondary and side roads, railways, trails, wooded areas, waterways including lakes, rivers, streams and rapids, bridges, buildings, mills, power lines, terrain, and land formations. This map was published in 1994. Maps were produced by Natural Resources Canada (NRCan) and it's preceding agencies, in partnership with other government agencies. Please note: image / survey capture dates can span several years, and some details may have been updated later than others. Please consult individual map sheets for detailed production information, which can be found in the bottom left hand corner. Original maps were digitally scanned by McGill Libraries in partnership with Canadiana.org, and georeferencing for the maps was provided by the University of Toronto Libraries and Eastview Corporation.
