    Description

    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).

    The data and maps cover most of Ontario and contain many features normally found on topographic maps such as relief, hydrography, vegetation and roads.

    Description

    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.

    Description

    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 GIS software. * [GEO]: Geospatial Ontario * [GIS]: geographic information system

    Description

    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.

    For more detailed information about this dataset, refer to the associated User Guide.

    Now also available through a web service which exposes the data for visualization, geoprocessing and limited download.

    The service is best accessed through the ArcGIS REST API, either directly or by setting up an ArcGIS server connection using the REST endpoint URL. The service draws using the Web Mercator projection.

    For more information on what functionality is available and how to work with the service, read the Ontario Web Raster Services User Guide. If you have questions about how to use the service, email Geospatial Ontario (GEO) at geospatial@ontario.ca.

    Description

    Geographic Township is a polygon feature that indicates the fundamental land subdivision fabric of the Province. Each Geographic Township area may or may not be the same as the jurisdictional area of the township.The location of township lines on the Ontario Base Maps (OBM) were determined by using a combination of both survey information, i.e., retracements, original township plans, surveys notes, etc.; and OBM physical features such as roads, trails, fence lines, and water bodies. In some areas where there were almost no OBM physical features available, aerial photographs may have been used to help determine boundaries. Unorganized areas are derived from Ontario Ministry of Natural Resources Base Map Areas.Data are available in ArcView® 3.x format.

    Available on CD Rom at the Map and Data Library. CD #254.

    Description

    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.

    Description

    The Ontario Toponymic Database (OTDB) is a centralized source for government approved geographic names, their locations and physical extents/boundaries (where known). It is the geographic naming policy authority and provincial record keeper specifically for geographic feature and unincorporated place (community) names in Ontario. This information holding also contains select sets of official government names authorized by other authorities (Municipalities, Federal Government, etc.) that have been geo-referenced to similar standards as the core feature and community name sets.

    Additional information collected includes: data on the status of proposed and rescinded names, name origins, name histories and treatment of official names in other languages. The current standard digital product contains: Official and official alternate names; French-text Equivalent names; linguistic treatment code; feature type; UTM and latitude and longitude references at feature centroid/river mouth - NAD83; Ontario Basic Map and National Topographic Sheet references at feature centroid/river mouth.

    Description

    Static flood inundation boundary extents were created along the entire shoreline of Lake Ontario in Cayuga, Jefferson, Monroe, Niagara, Orleans, Oswego, and Wayne Counties in New York by using recently acquired (2007, 2010, 2014, and 2017) light detection and ranging (lidar) data. The flood inundation maps, accessible through the USGS Flood Inundation Mapping Program website at https://www.usgs.gov/mission-areas/water-resources/science/flood-inundation-mapping-fim-program, depict estimates of the areal extent and water depth of shoreline flooding in 8 segments corresponding to adjacent water-surface elevations (stages) at 8 USGS lake gages on Lake Ontario. This item includes data sets for segment F - Lake Ontario at Breakwater Light 2 near Fair Haven, NY (station number 04232093). These datasets demonstrate the estimated extent and depth of lake flooding at specific water levels of 1-foot increments from 247.0 ft to 251.0 ft (International Great Lakes Datum of 1985). In this study, wind and seiche effects were not represented; therefore, the flood inundation maps reflect five stages for Lake Ontario that are static for the entire shoreline area of the lake. In this study, wind and seiche effects were not represented; therefore, the flood-inundation maps reflect five stages for Lake Ontario that are static for the entire shoreline area of the lake. This item is a package of flood inundation data for segment F - Lake Ontario at Breakwater Light 2 near Fair Haven, NY (station number 04232093) including: 1) 1 shapefile showing 5 estimated flood extents as polygons, 2) 5 raster datasets showing the depth of the water at 5 flood stages, 3) 1 shapefile showing the study limit extent of segment F, and 4) a metadata file. The polygon flood extent shapefiles were developed from digital elevation models (DEMs) derived from the lidar to represent the estimated areal extent for five flood stages for segment F. The raster files depict the depth, in feet (referenced to the International Great Lakes Datum of 1985), of the water in the inundated areas along the shoreline of Lake Ontario during the five theoretical flood stages. The depth grids were created by subtracting the digital elevation model (DEM) values (in feet) from each of five raster files representing the flood extent at each constant water level (in feet). An approximately 100-meter buffer was used as the extent into the lake.

    Description

    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.

    Description

    These data provide an accurate high-resolution shoreline compiled from imagery of LAKE ONTARIO, SOUTHWICK BEACH TO WOLFE ISLAND, NY-ONT . This vector shoreline data is based on an office interpretation of imagery that may be suitable as a geographic information system (GIS) data layer. This metadata describes information for both the line and point shapefiles. The NGS attribution scheme 'Coastal Cartographic Object Attribute Source Table (C-COAST)' was developed to conform the attribution of various sources of shoreline data into one attribution catalog. C-COAST is not a recognized standard, but was influenced by the International Hydrographic Organization's S-57 Object-Attribute standard so the data would be more accurately translated into S-57.
