I Spy With My Little Eye
An Aerial Imaging Strategy forSt. Albert
Tammy Kobliuk – City of St. Albert
Pictometry and St. Albert
• A little about us• How our imagery has evolved• Where Pictometry fits into the picture• Building the business case• Our current status• A window into how it is being used
A Little About St. Albert
• Capital Region – beside Edmonton• Approximately 61,000 residents• Approximately 50 sq.km. (small)
• Primarily urban residential (yuppies)
• High service delivery expectations (you have no idea)
• High taxes (so we’re told over and over again)
• God’s country (even the magazines say so!)
• The Botanical Arts City
Our Imagery Evolution
• Hardcopy 9x9’s• Black and white scanned photos• 25 cm black and white digital orthophotos• 10 cm colour digital orthophotos• LiDAR DEM and Surface Model• Pictometry (partial coverage and level)• Pictometry (completion and in-fill)• Pictometry (complete coverage)

Where Pictometry Fits
• We see it as a vital part of our imaging strategy
• In a very short time it has become very important to a lot of staff
• We automatically assess new staff for their need of it
How It Looks Now
• Capital Region (ERJOI)– Every two years
• Pictometry– Every two years– Offset from ERJOI
• LiDAR– Every five years
Building the Business Case
• Provides a digital view unavailable from other sources.
• Increases the ability to do work from the desktop.• Decreases the need for field visits.• Provides a detailed daytime view for night time
work (e.g. emergencies)• Cost effective compared to regular photography.• Cost effective to roll out to users.• Access to other client image libraries.
Return on Investment
• No visible budget decrease• Increases the efficiency of existing staff• Provides a more complete information picture
to capture better data• Provides a more complete information picture
to make better decisions• Cloud software has minimal impact on
required IT resources
Pictometry and LiDAR• Pictometry is 3D aware• DEM used to embed Z information into each pixel• Quality of source Z information affects:– Quality of reference points– Embedded pixel elevations– Image registration
• Which in turn affects:– All measurements– Elevation contour generation– GIS data overlay accuracy
Our Current Status
• 7.5 cm resolution• We now have full coverage at all levels• Urban area – 2012 coverage• Rural area – 2013 coverage• Active construction areas – 2012 and 2013• 103 active POL users• Users in almost every department• OUR MOST POPULAR GIS APPLICATION
Deployment• Currently Pictometry Online• Only two ArcGIS extension users• iPad mobile application• Planned: Smartphone mobile application• Planned: Geocortex Essentials integration
Pictometry Online
• Viva la cloud!• 100 concurrent user level– 500 named users
• A number of GIS layers loaded– We take the lead from our users
• 95% of users are required to take training• Little requirement for technical support
Pictometry Online• Turn-key• Easy to use• Easy administration• Can be a bit flakey• Clunky as far as GIS goes• Cool that we can see Edmonton• Manual upload of shapefiles or KML• Needs work on cartographic capabilities• Needs work on reporting• Future: SDE data connections
Our Biggest Users?
• Assessment• Recreation• Public Works• Engineering• Development• Fire Services• Municipal Enforcement
Use Case: Property Assessment• Checking property conditions against real property
reports• Checking for additions• Checking measurements• Pre-visit preparation
Use Case: Examining Encroachments
See details of park encroach-ments
Use Case: Bus Stop Review
• Need to check every bus stop in the city• What does the location look like?• What infrastructure is there?• Ground conditions?• What infrastructure?• Cost planning• Making measurements
Use Case: Park Infrastructure
• Where is the infrastructure?
• What type is it?• How does this
match to our non-spatial information?
Use Case: Fire Pre-Planning
• General property layout• Structure shape and size• Structure materials• Building/property entry points• Access barriers• Fire infrastructure locations• Roof layout– Vents– Access points
Use Case: Landscape Change
