From the links posted as comments I identified a couple of misconceptions I had about projections and gathered this quick summary. It should be mentioned that many projections don’t truly preserve any attribute. Their intent is typically to minimize all types of distortion thereby not eliminating it in any specific property. Jack of all trades, master of ...

It actually seems very reasonable from a price perspective. I would specify it meets XXXX standard of accuracy and I would specify the file be in las 1.2 (or another spec as desired). Specify the classes you require and the RMSEz that is acceptable (often just vertical in lidar). 7 points per m is high. I find this document very useful. It spells out what ...

EPSG has added it as 6647. At Esri, I have it in a development build, but it's not in ArcGIS 10.3 (hopefully 10.3.1). Here's the Esri WKT for it: VERTCS["CGVD2013_height",VDATUM["Canadian_Geodetic_Vertical_Datum_of_2013"],PARAMETER["Vertical_Shift",0.0],PARAMETER["Direction",1.0],UNIT["Meter",1.0],AUTHORITY["EPSG",6647]] This document on height ...

This looks to me like a one degree wide and half degree high sheet layout of topographic maps similar to NTS. Created with QGIS using vector raster. The numbering looks like a combination of West and North coordinates in 1/10 degrees. This map contains an overview of 1:100,000 maps with the same numbering scheme: http://www.mnr.gov.on.ca/stdprodconsume/...

The forward sortation area (FSA) is only the first 3 characters in the six character Canadian postal code. You need to include the local delivery unit if you want unique values. From here:

If you load Natural Earth data into PostGIS, you can extract the extents of each province with a query: WITH provinces AS (SELECT name, ST_Envelope(geom) AS geom FROM ne_10m_admin_1_states_provinces WHERE admin = 'Canada') SELECT name, ST_XMin(geom) AS xmin, ST_YMin(geom) AS ymin, ST_XMax(geom) AS xmax, ST_YMax(geom) AS ymax FROM provinces; ...

This is caused by points too far north, and too far west. For the too far north, it occurs when the source is not in lat-long, but another projection such as Lambert conformal conic (used by the government), and then the data is changed to a un-projected coordinate system. The solution is to remove the few vertices that are too far up north. The second ...

You can use the data from openstreetmap. The data is free and can be obtained from overpass api. Here is a link to overpass turbo

The default projection in D3 is the U.S.-centric d3.geo.albersUsa projection. This is a composite projection design to display the 48 contiguous United States, Hawaii, Alaska and Puerto Rico. If you want to make a map of Canada, you’ll have to specify the appropriate projection rather than relying on the default.

The AB_CSRS file seems to have been replaced with abcsrsv4.dac. Esri hasn't added another transformation to use the new file yet (we don't have a copy). You could rename it and use the NAD_1983_To_WGS_1984_8 transformation, or create a new transformation with the geoprocessing tool, Create Custom Geographic Transformation. You will still have to change the ...

Natural Resources Canada Geogratis (CanVec) 1:50,000 is the best and most up to date Canada-wide data available, at Open Data Canada. This is the same data used in the official CanTopo CanMatrix 1:50000 paper maps and the same data that's used for the ArcGIS Online World Topographic basemap altough GeoBase, Agriculture and Agri-Food Canada are also listed. ...

Your raster layer is Pacific centered (0 ~ 360 degrees), while the bluish polygon is in -180 ~ +180 degrees space. You will have to decide which x-range you will use. I think most people will choose to modify vector layer since Affine Transformation is available in many GIS software. For instance, QGIS has Translate tool (Processing Toolbox > Vector ...

It is usually more meaningful to compare quotes from different providers for the same situation/contract. However, I tried to make a rough comparison with the work of Hummel et al. (2011). OP. 30k CAD / (70 Km² x 247.105 acres/Km²) = $1.73 CAD/acre or $1.92 USD/acre. (Considering a ratio of CAD/USD = 1.11 in Oct/2014). Hummel et al. (2011). They report ...

Canadian Hydrographic Service may be your only choice, I'm afraid. LIO is supposed to have line and point bathymetry data, but their login and search tools are going off into hyperspace for me right now. My friend was lucky in that the lakes he was interested in had just had a very detailed survey in advance of the G8, and CHS (apparently) don't maintain ...

Try the LIO Metadata portal. Search for Crown Land Use Atlas and you'll find a couple of items that may be what you're looking for.

This might be better as a wiki. In British Columbia, civic addressing is maintained by local governments (ie, municipalities and regional districts). Depending on what your use is for the data, they can often be obtained by simple data requests directly to those local governments if it's not publicly accessible already. The data you get might not be under ...

Download the polygons (shapefile) instead of the coordinate data which is just an ascii list. Open the shapefile using QGIS as I originally suggested and Save As to a kml file. Alternatively use Google Earth Pro (currently free), Shp2kml, or another online converter to do the conversion. Upload the kml file to Google Maps.

You can use Open Street Map Nominatim API for Geocoding and it will return the bounding box Example: Manitoba, Canada http://nominatim.openstreetmap.org/search?q=Manitoba,%20Canada&format=xml&polygon=1 Response (xml) boundingbox="49.9971285,49.9972285,-96.8892673,-96.8891673" polygonpoints="[[-96.8892173,49.9972285],[-96.889181944661,49....

Quebec is big you can find open data by individual municipality. To get you started here is Quebec City http://donnees.ville.quebec.qc.ca/catalogue.aspx Has many formats common to GIS (shp,KML,DWG etc). Note: Not all municipalities have the same level of opendata, property parcel might have be sourced another way (aerial, LiDAR, imagery). For Smaller ...

The polygon is not "wrong", it's just not representing landmass It uses 1 polygon for each province. You can find polygons representing Canada's borders and land surface on GADM or DIVA-GIS

I'm not sure about shapefiles, but a basemap dataset ("cartographie de base") is provided here: http://donnees.ville.montreal.qc.ca/dataset/cartographie-de-base It's available in DWG format and contains a buildings layer:

You can download the 2015 LiDAR data (including buildings - class 6) here. 3d models of buildings for certain boroughs are available here and here. You can also get OpenStreetMap extracts for Montreal from MapZen here.

Maybe "Statistics Canada": http://www12.statcan.gc.ca/census-recensement/2011/geo/bound-limit/bound-limit-2016-eng.cfm has census boundaries, you'd need to dissolve the internals to get a country outline and it would still be quite a large file.

I am afraid, there are none. But Esri's Network Analyst supports something called live / historic traffic which can be embedded into a network dataset. You might look for other 3rd party sources of this information, mine it, do some ETL, and then configure your network dataset to use this traffic information. This is quite a lot of work. Your other option ...

Unlike some other provinces (see list in answer comments). There is no specific transformation from NAD 1983(Original) to NAD 1983(CSRS) specific to the Northwest Territories, or to Canada as a whole. I have used the assumption that the differences between NAD 1983(Original) and NAD 1983(CSRS) are negligible (Figure 2.,Craymer, 2006) for specific areas. ...

If you check the official definition in the EPSG Geodetic Data Registry, it lists: Remarks: Used as part of NAD27 to/from WGS 84 transformation for offshore oil operations - see code 8647. Scope: Accuracy 1 to 2 metres. Used for oil industry operations only. Information Source: Various oil industry sources. The transformation parameter values are ...

NRCan has a NTv2 web tool that can be used to transform coordinates between the NAD27, ATS77, NAD83(Original), and NAD83(CSRS) reference systems using the binary Grid Shift Files obtainable from the relevant provincial offices. You can use this tool to determine if it's worth going through the effort of tracking down and acquiring the GSB shift files from ...

Where are the resources and tools to make using this stuff easier (or even possible)? Geogratis from Natural Resources Canada now has a web based data extraction tool @ http://geogratis.gc.ca/site/eng/extraction It's really easy, I tried it the other day. First you can just select your Clipping Area by either: Current map extent Predefined clipping area ...

The FSA shapefiles are up now at http://www12.statcan.gc.ca/census-recensement/2011/geo/bound-limit/bound-limit-2011-eng.cfm I just downloaded them, now only if there was an LDU shapefile available... Here is a picture of the LDU shapefile loaded in QGIS and zoomed into Stanley Park in Vancouver BC: The data is available through the Platinum Postal Suite, ...
