How to download a #GIS #orthophoto #image using #Vancouver #Open #Data

Ever have one of those late GIS nights, when something so simple can be so complicated and tedious.  It happens all the time.  So for those of you who need a quick tutorial on download Vancouver Open Data, here is.

In this video, we’ll walk through how to download data from Vancouver Open Data.  If you’ve watched my other tutorials, you will notice that this is one of the datasets I do use. The last time I used this dataset was when I did a tutorial on label orientation and style (click here for a glance Part 1, Part 2, Part 3) and an awesome conversion to #KML to open in Google Earth.

As always, I do encourage using open data.  It’s free and accessible to the public.  One message to take home from this video is that orthophoto downloading are quite similar across all platform.  There is usually:

1) a metadata that will tell you about that data.  This is where you find out about the resolution, the features, what techniques were used to capture the data and how old it is.

2) You’ll usually be directed to a graphic screen comprised of tiles.  Some other resources like GeoBase, will actually let you direct download from their FTP.

3) When you do download, make sure you’re on a UTM project, especially if you are calculating area.

Happy GIS-ing
