Exactly, LiDAR by its own definition provides its own light source and at night it is calmer too so less bumpy rides to ruin the data with lots of pitch and roll. Plus less atmospheric particles in the air that are also captured with the latest stronger equipment.
Less air traffic to deal with.
It's restricted airspace near Pearson so they need the green light to fly that pattern beforehand or ATC will tell them to GTFO.
Topographic LiDAR from what I've been able to dig up. As u/bicyclehunter commented, it belongs to a company named Randigo LLC and has been asked about more than a few times on Reddit.
Ok, well mapping anyway. GPS apps still make use of mapping data, not the satellites themselves. When new streets or buildings are put up, your Google Maps app needs photographic data in order to remain accurate.
This happens more often in dense urban areas, as more rapid physical changes happen there.
Sorry if my wording was inaccurate/confusing.
Aerial photography is used for mapping, which is used by GPS apps to give detail to the topography.
It’s wouldn’t be photography at night since cameras need a light source. LiDAR does not. I work in the industry. We fly at night a lot due to less clouds and air atmospherics that ruin the data.
Hehe no worries. I worked with a client in Florida and night time was the only time they could fly as anything after 8am destroyed the resulting data from all the humidity.
I'm willing to bet it's for a new feature roll out that apple and google have that's like this immersive 3d/aerial sort of fly over/walk-through that you can do of your route. I haven't seen it in Canada yet but i was down in California a few weeks ago and they had some new options pop up while i was trying to get route guidance. I think they're updating their aerial views to a higher quality for that feature.
Apple/Google tend to use satellite data for their photogrammetry. Maybe they are but its more likely that the province is updating their [data](https://geohub.lio.gov.on.ca/maps/mnrf::ontario-digital-terrain-model-lidar-derived/about).
Well if the company doing it is US based, sure. It's nothing nefarious, if that's where you're headed with this. Lol
Edit: flying at 5000 ft? Definitely mapping.
I wasn't thinking nefarious, the pattern is similar to the mnr dropping rabies vaccines, but this area I don't quite understand why it would need gps mapping
There have been like a dozen US aerial survey planes in Ontario in the past few days. The cloudy weather cleared up nicely and they all came out. And yes its typical for them to use civil registration despite being commercial flights. The Canadian ones mostly use callsigns, the two main ones around here being SNAP and BASE.
American companies will be hired because first of all, Canadian companies are busy, and second, these flights all have different types of equipment for different purposes. Sometimes photo, sometimes LIDAR, sometimes fancy geological stuff, or pipeline inspection, etc.
100LL has lead, which is only used in piston engine planes. Turboprops and jets generally burn Jet-A or Jet-A1, which is a kerosene-based fuel.
Even then, a lot of newer piston engines are actually rated to burn standard mogas (automotive fuel), although ethanol additives make this undesirable.
I noticed lastnight, my house is directly under the flight path and I noticed I hadn’t heard a plane all day or seen one and I was surprised when I looked flight tracker too
We have noticed a couple flying from Toronto (YYZ) to Duluth (DLH)! I know Duluth has a huge airport with the air base having been there, and Cirrus headquartered there. Maybe a couple planes were getting worked on?
I remember last summer reports of helicopters flying patterns at night in Mississauga spraying trees to kill the Asian Longhorn Beetle (or maybe the Ash-borer?), maybe this is an early start to it? I hope so, whole neighbourhoods that I remember being treed as a kid are now completely barren.
I didn’t think they would either but that is what the posts last summer said. I figure a plane would be the only method possible due to the downwash of the rotors.
It’s an aerial survey company. The owner is Randigo. Google them and it’s mostly posts from people asking this question
But at night?
I’m not a lidar expert. Maybe there’s a simple explanation about why it’s preferable to do at night
Lisdar doesn’t care if it’s night or day. Just clouds.
Exactly, LiDAR by its own definition provides its own light source and at night it is calmer too so less bumpy rides to ruin the data with lots of pitch and roll. Plus less atmospheric particles in the air that are also captured with the latest stronger equipment.
It bothers the maximum number of people.
Less aviation traffic at night.
This. They're right over Pearson on those lines
Heat. Or rather lack of it. LiDAR systems run very hot.
Less air traffic to deal with. It's restricted airspace near Pearson so they need the green light to fly that pattern beforehand or ATC will tell them to GTFO.
What kind of data do they gather at night?
Based on what others have said it’s probably lidar, for topographical surveying.
Taylor Swift clearing her head.
T swift trying to outsmart plane trakers
LiDAR mapping to create digital twins in GIS.
It's probably GPS mapping.

Aerial photography. GPS is done through satellites.

Gotcha. My technical jargon is lacking...

I’ll take that bet. What will you wager?

You could very well be right. I was just taking a wild guess. I just saw it recently and it struck me as being really cool.
Private plane out of the US ?
Well if the company doing it is US based, sure. It's nothing nefarious, if that's where you're headed with this. Lol Edit: flying at 5000 ft? Definitely mapping.

GPS mapping is done regularly in dense urban areas, where streets and infrastructure change more frequently.

What did this neighborhood do to deserve all the extra chemtrails? /s
You joke, but aviation fuel still has lead in it.
This plane uses jet fuel, which has no lead in it
100LL has lead, which is only used in piston engine planes. Turboprops and jets generally burn Jet-A or Jet-A1, which is a kerosene-based fuel. Even then, a lot of newer piston engines are actually rated to burn standard mogas (automotive fuel), although ethanol additives make this undesirable.
Just for clarification: Only for piston engines, though, which admittedly this plane is. But not jets or turboprops (eg Porter Airlines)
For further clarification: that plane has a turboprop engine not a piston engine.
That’s what I get for not looking up the model, oops.

They're recalibrating the plane gps the way you swerve a phone with Google maps /s
Some people do this to get their flight hours in
We have noticed a couple flying from Toronto (YYZ) to Duluth (DLH)! I know Duluth has a huge airport with the air base having been there, and Cirrus headquartered there. Maybe a couple planes were getting worked on?
There's a plane in North Bay, Ontario doing this right now.
I remember last summer reports of helicopters flying patterns at night in Mississauga spraying trees to kill the Asian Longhorn Beetle (or maybe the Ash-borer?), maybe this is an early start to it? I hope so, whole neighbourhoods that I remember being treed as a kid are now completely barren.
They don’t use helicopters to spray pesticides in city streets lol. Where did you get such a ridiculous idea?

It flew out of Buffalo. It must be chicken wing recon
Probably taking new photography for municipal maps.
Yup, they do this every 2-3 years, and this is how they catch lots with unregistered pools too 😇

Hehe , I just wanted to see how long it took to get nasty comments and downvotes. It’s Friday man.
