TRX is a free online coordinates transformation tool that allows users to transform coordinate values between between different geometric reference frames such as NAD83(CSRS) & ITRF), epochs and coordinate systems such as geographic, cartesian and local projections systems (UTM / MTM etc.).
GeoAlliance Canada Receives Funding to Promote Use of Geospatial Data and Tools
Dec 14, 2015 – Today the Canadian geospatial community received a significant economic thanks to a new funding contribution agreement with Natural Resources Canada. GeoAlliance Canada, a national non-profit umbrella type organization launched earlier this year, received the funding in support of a new mandate to provide essential leadership within the geomatics sector and the geospatial community.
Through the engagement of key groups and organizations, GeoAlliance Canada has begun to articulate and promote the benefits of using geospatial data and tools for effective decision making to leaders within business, government and education circles. The contribution funding from Natural Resources Canada will have an immediate impact by providing essential operational resources for this fledgling non-profit organization.
For more information about GeoAlliance Canada or this contribution funding agreement to Promote Use of Geospatial Data and Tools, please check out the GeoAlliance Canada website.
A magnetic declination is the angle between the the horizontal plane and magnetic north (direction your compass needle points) and true north (actual direction along a meridian towards the North Pole). Magnetic declination varies both from place to place as well as over time. The magnetic declination varies depending on where you are located on the Earth’s surface, and varies over time.
Magnetic Declination Calculator
Natural Resources Canada provides a free online magnetic declination calculator that can be used to calculate magnetic declination for any location and date based on the International Geomagnetic Reference Field model.
Natural Resources Canada (NRCan) has recently launched a new update to the already innovative GeoGratis website (Note: although it has gone live it is still in beta mode). GeoGratis is a web portal that provides access to a wide collection of Canadian geospatial data, maps, images, and publications at no cost and without restrictions.
All data accessed via GeoGratis comes with an Unrestricted Use Licence Agreement that grants users a non-exclusive, royalty-free right and licence to exercise all intellectual property rights in the data including the right to use, incorporate, sub-license, modify, further develop, and distribute the data. The various downloadable geospatial data, maps, images, and publications in several different popular formats such as geopdf, geotiff, pdf, shape file and tiff.
Improvements to the new site made go much deeper then just minor cosmetic changes. GeoGratis Website is now easier to use and allows access to better search tools where one can now view and download all available geospatial data sets consolidated into the same web site.
The new Platform also now better supports developers that want to create unique and innovative mapping applications with Canadian data, images and documents using one of the three available GeoGratis Application Programming Interfaces (API’s). These include the GeoGratis API, the GeoLocation API and also an updated Canada base web map service (WMS) that now also includes Canadian transportation data (Canada Base Map for Transportation – CBM-T).
NRCan feels that the new GeoGratis service is compatible with OpenGIS® Consortium (OGC), innovative and cutting-edge, and will provide a better one stop site for people to obtain Canadian geospatial data, maps, images and publications.
The New GeoGratis Website: An Innovative Geospatial Platform for all Canadians; consolidates several location-based services including The Canadian Geographical Names Database (CGNDB), Atlas Gazetteer, Postal Codes and National Topographic System (NTS) Map search. The CGNDB manages names records for populated places and physical features across Canada. Users can search by geographic location using the map of Canada, name, physical feature, subject, NTS number or product title.
NRCan has been listening to what the geomatics community has been asking for all along. And as a result have taken what was already a pretty good service that offered free data and information and consolidated it together, cleaned it up and then added some more tools as well.
Therefore one should only expect that with all this royalty-free geospatial data and API tools now available that we should start to see more Canadian Cities and Municipalities start to offer web mapping sites and geographic information for their citizens.
Take a look at the new and improved GeoGratis Website for yourself using either the new search interface or simply browse through the extensive directory listing of hundreds of different maps, imagery and geospatial data sets to discover what the Federal Government of Canada has to offer the geomatics community.
GeoGratis is an internet portal web site provided by Natural Resources Canada. It is designed to offer Canadians with digital geospatial data free with limited restrictions. So far this year Natural Resources Canada has released over 350 updated or new topographic map sheets and made them available to the public in what they refer to as the CanTopo series via the GeoGratis web site [geogratis.gc.ca].
CanTopo is considered the next generation of topographic map sheets that provides quality spatial information that fully complies with international geomatic standards. The digital maps are considered multipurpose because they can be utilized for a wide range of uses from many different organizations and individuals. Georeferenced versions can also be used with Global Positioning System (GPS) receivers and other digital geographic data sets with various software packages such as Google Earth, ArcMap or Global Mapper. You can also simply print them and use them the way they are, as regular NTS paper maps, just like most of done for years.
The spatial reference system CanTopo data is Universal Transverse Mercator (UTM) referenced to the North American Datum of 1983 (NAD83) in the Canadian Spatial Reference System (NAD83CSRS). A Downloadable file formats include PDF, GeoPDF, TIFF, and GeoTIFF. For more information on these digital products you can refer to the official product specification sheet.
Some of the new maps released this year include ones covering parts of our Canadian northern regions that were previously unmapped at a 1:50k map scales, and also several map updates for areas in Ontario, Manitoba, Nova Scotia, New Brunswick and Saskatchewan. Here is a short list of some of the new topographic maps available on GeoGratis.
They have the digital files available via ftp [ftp://ftp2.cits.rncan.gc.ca/pub/cantopo/] if you know the map code for the map sheet you are looking for or you can also go to the CanTopo search tool to search for the map codes and regions that are available (More CanTopo map sheets are scheduled to be published quarterly) to start searching and downloading maps for your own use.
The Atlas of Canada recently published a beautiful new cartography product featuring the Canadian North in support of Natural Resources Canada and the Government of Canada’s Northern Strategy.
The new bilingual map product (available either in paper or digital formats) features the vast geography of the north from approximately 50° latitude and above. The map highlights populated places in all three Canadian territories, northern sections of the provinces, and also adjacent northern regions ofAlaska, Greenland andRussia.
The Canadian North is a fundamental part of our country, part of our heritage and key to our future. It has an extensive geography from the boreal forests north to the tundra, across the permafrost regions and the ice of the Arctic.
The Atlas of Canada provides Canadians with current accessible geographic information products covering the entire country. It was first published in print in 1906 and then in 1999 became one of the first online electronic atlases in the world. Today, the Atlas of Canada continues to provide Canadians with a diverse cartographic collection of maps, data, images and other related resources.
“The Atlas of Canada Web site will provide the most interesting, dynamic and comprehensive collection of maps and related information about Canada available anywhere on the Internet, with effective and intuitive tools for users to access them.”
The Atlas of Canada provide free downloads of new map of the Canadian North in either JPG or PDF versions. They no longer sell map products directly to the public but do make hard copy versions available to purchase through various dealers all across the country. So if you do not have the ability to print your own copies you can still get paper products.
