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 […]

FBS data doesn’t line up with City of Toronto data.
FBS data is usually in UTM NAD83 Zone 17N. City of Toronto offers their data in MTM NAD27 Zone 10. Some of the files may need to be re-projected into to a common coordinate system in order to align properly, a simple procedure for vector files. If you require imagery to be reprojected, however, contact […]
How to determine which layer I’m looking at in VuMAP?
The layers will draw in the order you see them in the layers list, drawing the bottom most visible layers in the list, then drawing the visible layers above it over top. Since the imagery is opaque and completely covers an area, it will hide any layers that have drawn below it. In the image […]
Can I have several image tiles merged into a single file?

Our staff can combine the tiles into a single large image while still maintaining the geographical referencing, provided the tiles you’ve chosen have the same photo resolution and file format. A fee for custom labour […]
Why are there sometimes negative values for elevation in the DEM?
Some tiles have 1000m vertical shift applied, to work with a different global origin. For example, a value of -800m should be considered +200m.
Nothing draws in VuMAP
There are two reasons why this may occur. 1. Some layers are too detailed to draw when you are zoomed out to view a large area. Below the name of each layer, you’ll see “Zoom Levels: [#-##]” which indicates how close you need to be zoomed in before the layer will start to draw. You […]
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 unlabeled roads. There are a few options to give context to to the surrounding area. You can take advantage of the georeferencing inherent in […]
