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 th...

My DEM tiles are just a bunch of lines. How do I use this?
Only elevation information is included, either as DEM or contour, depending on the file you’ve chosen. The road edges frequently appear as break lines in the DEM, giving the appearance of unlabe...
How is flood mapping different from other elevation maps?
Other elevation models are simply a record of the elevations across an area. Modeling and flooding predictions made by any agency other than the Conservation Authority are of no regulatory effect. The...

Can I get data in other formats than the options I see online?
Yes. FBS makes the most popular format types available on MapWarehouse, however, we can also perform file format conversions on request. An extra fee for labour may apply.
What’s the difference between 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 d...
Can I get a sample file to try in my own software?
