The property lines don’t match the image below.
The orthophoto are generally spatially accurate to double the resolution value. Simply put, if a photo has resolution of 20cm, any point on the photo will be accurate within 40 cm of its true location. For the parcel data, different Land Registry Offices in Ontario were originally drawn to different standards and then later integrated […]
I plan to drill a well on my property, will your groundwater data help me?
Yes and no. While the data can be used to identify good places to drill wells and identify flow direction to help identify the source of groundwater contamination, these services are best left to qualified professionals. The average landowner will not be able to correctly interpret or make use of this information on their own.
What’s raster and vector?
“Raster” refers to data made of pixels, like our orthophoto. Common raster file types you’ll find on our website include JPG, MrSID, GeoTIFF and ECW. “Vector” refers to data made of points, lines, polygons, and often includes text elements as well. Common vector file types you’ll find on our website include SHP, DWG, and DGN. […]
How can I convert the geometry of adjacent parcel tiles from polylines to polygons?
Polygons would not be a good representation of the data in this case because the geometry of the parcels is clipped to the boundary of the tiles, so the area, perimeter, and parcel boundaries of the properties on the edge of the tile would be misleading. A closed polyline indicates the entire property is included […]
Can I buy printed hard copy maps?
FBS can produce large format custom printing of our digital data products. These printed maps typically include a large map portion with orthophoto, road labels and property lines, and a title block containing the title, scale, scale bar, north arrow, photo details, data source details and disclaimers, print date, our logo, and can include other […]
The parcel tile I downloaded is just a couple of lines
Large properties often span several tiles, you’re seeing only the portion of the parcel boundary that crosses the particular tile. You will either need to buy all the tiles that your property intersects and combine the boundary lines, or, request a quote for a custom order for the specific parcel. For a small order of […]
What format is groundwater data offered in?
Moraine groundwater are presented as asc files (ASCII grid). The asc file is a raster dataset similar to an image, where each pixel value represents an elevation value rather than a colour. Each of the asc files represent the elevation where you would find the various levels of substrate (e.g. Kettleby Till) along with the […]
What are the intervals of the contours?
The contours provided in tiles by FBS on MapWarehouse are in 1m intervals. In any area where high resolution orthophoto is available, it is usually possible to produce a more detailed elevation model. Contact us for a quote.
