How detailed are the images?
The amount of detail depends on the image resolution. Resolution in cm refers to the area on the ground covered by each pixel in the image. In an image with 15 cm resolution, for example, each pixel...
What’s the horizontal error of the orthophoto
It depends on the photo resolution. Whatever the stated photo resolution in cm, positional accuracy is double that value. A 15 cm photo, for example, has positional horizontal accuracy of +/- 30 cm. T...
I searched for imagery but it’s the same as Google.
The Google base map is just to help you locate your area of interest. From the item selection list in MapWarehouse, click the info icon beside any item to see it’s metadata and a thumbnail of th...
Is the date and time of the photo included?

How is the data priced?
Most downloadable data is priced based on 500m x 500m tiles. For most orthophoto, the cost is $70 per 500m tile, and $150 per 1km tile, with progressive discounts applied automatically for orders grea...
Where can I find sample data?
Several sample files are available in different formats on FBS University.
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...
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 c...
How accurate is the elevation data?
In the 2002 Golden Horseshoe data set, the horizontal and vertical accuracy is +/- 40 cm, and +/- 80 cm for the 2002 Simcoe-Kawartha data set. This means that the difference between the true elevation...
