Bathymetry of Lake Ontario
Bathymetry is used to measure water depths to help model physical underwater terrain found beneath large bodies of water. Similar to the same way that LiDAR models are represent 3D features (or relief) of land terrain, bathymetric maps illustrate the terrain or land that is located under large bodies of water. Color ramps created from depth contours or isobaths help make the variations in relief easier to see.
“High-resolution digital bathymetry makes possible meaningful quantitative estimates of available habitats for fish and other living organisms. In other lakes these estimates have been used to formulate regulations intended to prevent overfishing. Conversely, Great Lakes bathymetry is much in demand by anglers as an aid in locating the most promising areas for fishing.”
The Bathymetry of Lake Ontario was the third poster map released by National Oceanic and Atmospheric Administration (NOAA) depicting highly detailed bathymetry data ( at 2 meter contour interval) of the Great Lakes.

Because an unknown GIS file format can be every GIS analysts worst nightmare.
In a GIS career, a person will encounter a wide range of GIS formats. GIS technicians manage, share and create data in various geospatial data formats. Here is the Ultimate List of GIS Formats & Geospatial File Extensions, some are common while some are not so common.
Looking for Ontario Topographic Data?
Recently, someone contacted me looking for information on where they could find Ontario topographic data for the Thunder Bay area, so I assumed that they must have already checked the Canadian data page and suggested that they check out the Ontario Basic Mapping website (OBM).
The Ontario Basic Mapping (OBM) site by the Geography Network is a great online resource with simplistic interactive interface that provides users tools to create customized map views and the ability to download various topographic base mapping data for the entire Province of Ontario. The site contains GIS layers created from 1:10,000 base maps from the Ontario Ministry of Natural Resources that people can download including layers for transportation, water, municipal, elevation, parks and conservation areas. The portal created with ArcIMS makes it pretty easy to use and a convenient way to obtain mapping data in a variety of formats for virtually any area of interest in Ontario.
However, that person replied back to me a few days latter telling me that the site was only an online web map viewer and they needed actual data to use in a GIS, and wanted to know if I had any other sources of mapping information for Northern Ontario.
Now, I thought that the e-mail was a little strange since I have used data from the Ontario Basic Mapping web site before while planning various aerial surveys in Northern Ontario, so I decided to go check out the web site to see if the downloading data feature that I had used had been removed. Turns out the site is still the same, it can be used as an online web map viewer to customize and print maps but the downloading option still exists providing the ability to download the map layers in the viewer to use with your own GIS software packages like ArcMap or MapInfo.
It seems like a pretty simple mapping application to me but maybe it is not as obvious as some people need it to be, so I decided to share some of the notes on downloading topographic base data from the OBM site that I provided to them, in case others have trouble figuring how to download the data as well (And summarized in the video at the bottom).
The OBM site is an ArcIMS site with a simplistic look and an interactive interface that provides users with tools to create customized map views and the ability to download the various topographic base mapping data in the map window. If you are not interested in downloading GIS layers but still want to make some maps then like most typical map viewers, they also provide printing options where you can create either paper or digital PDF maps.
When you first open the viewer you are zoomed out to the full extent of the province with mapping tools represented by icons on your left and accessible data layers on the right hand side. Using the AOI icon, you first need to define an area of interest that will zoom the map window into your specific area, populating the map window with more detailed GIS layers and features.
From the list on the right hand side, you then select the visible layers that you wish to download. Next using the FME icon from the tools on the left hand side, a window will open up prompting you to log-in, create a free user name and password (or enter your existing log-in) and then a download options window will appear.
You then need to click a check box to agree with the license terms and click the Download Data button to continue. Finally another window with instructions for acquiring the data in a variety of formats (e.g. SHP, DWG, DXF etc.) and in either Latitude / Longitude or Lambert Conformal Conic coordinate system. Then there will be one final window with a message telling to check your e-mail for a message.
You will then get a machine-generated e-mail from the Geography Network with a custom download link with the Ontario topographic data layers that you specified for your area of interest that you defined. And that is all there is to it, so if you are looking for Ontario topographic GIS data layers to download or just want want to create online maps then the Ontario Basic Mapping (OBM) site could help you out.
If you know of other Ontario data sources that I have not yet added to the Canadian data collections then let me know about it and I will add it to the site.
Canadian Geospatial Directory
The Canadian Geospatial Directory contains basic information about the various Geomatics related companies found in and around Canada (with some from abroad) including many key aspects such as the companies basic info, contact info, web site info and geographic location. This section and our website continue to evolve over time as more companies are added.
To find a Canadian geomatics related company listing, simply use the simple search tool (that will allow you to search company names, Cities or postal code) found along the right hand side of the site or select a category from the navigation menu above.
We created the Canadian Geospatial Directory with the hopes that it becomes a comprehensive valuable online resource directory of geospatial related technologies, location-based services, and all geomatics related companies, organizations, education programs, and location related services in Canada. It uses Google maps to show spatial locations of services (when available) and advanced database search functionality to help people find services in their region.
We started adding content to the Canadian Geospatial Directory using our own database that contains over 1000 basic entries of various Canadian companies and organizations from coast to coast that work in the geomatics field.
But now it is time for the Canadian Geomatics community to help us further fill out the directory by contributing more information to existing basic listings and adding new listings for companies and services that have yet to be included. We feel this way the geomatics community can all help make the Canadian Geospatial Directory a valuable online go-to resource for anybody to find information about Geospatial companies, organizations and services in Canada.
Basic directory listings in the Canadian Geospatial Directory are free and may include logos, images, details, link to company or service, location etc. Many companies and organizations have more then one location so in order to be better represented on the online maps, multiple entries may be created.
So go ahead and search for your Geospatial related company, organizations or service, then if it has already been included, claim it and make any necessary changes.
Note: a FAQ is being created with answers to common questions about the Canadian Geospatial Directory – however feel free to send us any questions you have
To help fund the project, more comprehensive, “Enhanced” directory submissions are available for a small nominal fee and will provide people the ability to have a more detailed description, more images, videos etc. These listings will also be labeled “Featured” listings and appear at the top of categories and search results and be highly promoted through the Canadian GIS & Geomatics social networks – feel free to contact us for more information about this service.
Surrey launches OpenData Program
Surrey, BC –The City of Surrey launched its open data program today as part of its commitment to an open, transparent and accessible government. The new Open Data Catalogue comprises more data sets than any other municipality in Canada, and will increase efficiency and productivity for staff and public by making the data available to everyone on the City website.
More than 300 data sets comprise the catalog including City information often requested by the public such as:
• Crime statistics
• Restaurant inspection reports
• Statement of Financial Information
• Sustainability indicators
• imagery (orthophotos) & LIDAR
“The City of Surrey is committed to pursuing innovative best practices to allow for transparency and efficiencies through technology,” said Mayor Dianne Watts. “As a progressive City, the launch of the Surrey Open Data Program will empower our citizens by providing them with even easier access to City reports, statistics and information.”
Open data is the idea that certain data should be freely available to everyone to use and republish as they wish, without restrictions from copyright, patents or other mechanisms of control.
“Providing open data improves the public’s ability to easily access, download and utilize City information,” said Councillor Bruce Hayne, Chair of the Investment & Innovation Committee. “It also provides the additional benefit of eliminating the costs associated with related information requests.”
The City’s Open Data Program is a component of its ‘Smart Surrey Strategy’ which seeks to build a city that uses technology and innovation to transform life and work within its region in significant and fundamental ways. Using new and existing technologies and information, the Strategy identifies and implements systems to inform decision-making, create efficiencies and maximize its resources.
For more information, or to access the City’s Open Data Catalogue, visit www.surrey.ca/opendata
Over the past few years CanadianGIS.com has been highlighting and promoting various cities and provinces in Canada that have done a great job providing data and applications to the public.
We created this page a few years ago to collaborate links of all the open geospatial data info (sites that offer data downloads at no cost and without restrictions), fee based geospatial data, online web mapping applications and other great sources of geospatial information (including National, Provincial and Regional levels).
This comprehensive list of open geospatial data, fee based geospatial data, web mapping applications and cartographic products is a valuable asset to many people (… we get hundreds of emails and requests regarding “Where can I find data for …?”) so we continue to update it with new information and sources of Canadian data sets.
