Not that kind of dogging. Really!

Logging the dog walking with vlkgps on phone, visualisation using vikingGIS on desktop computer.

Images show: satellite map, speed/time, elevation/distance in that order.

looking pretty hilly for Norfolk there! What's the significance of the red dots vs the blue bits?

He goes out on his own?

Red dots are data points, I think. Blue bits are averages - there tend to be extreme peaks when the gps spazzes a bit (I never did anything at 47km/h, for example) and I suspect Viking is flattening those out.

Altitude isn't GPS's strongest point, unless you have either an altitude-capable sensor (I don't), or DEM data in yer vis. I did try to download the synthetic aperture radar scans of My Area off the internets for getting alt info from, but it didn't seem to work.

Puff - he probably would, as it goes - but too many Big Roads nearby for me to dare try. He's quite good at Road Drill (sit at side, wait for cars to go, cross carefully), but I don't think he'd stick to it on his own.

Could be a nice little project though.

I have seen this little project with a cat once. They put a small camera around it's neck and take random shots every couple of minutes.

"synthetic aperture radar" please translate, I only understand English

Puddlepuff says:


A system that uses electromagnetic waves to identify the range, altitude, direction, or speed of both moving and fixed objects, by a fiber not made from natural (animal, plant) materials that determines the cone angle of a bundle of rays.

Or summink or nuthink.

the bottom two look like images of exactly how a great walk goes--the red bubbly general joy part, and the blue is sniffy ground messaging.
