Using a jpg image/camera pic as a map + onboard calibration

[InfX]

Well, obviously, this is may not be easy, but this forum dir is called a "wishlist", isn't it  

How about using a jpg image from a camera (or any jpg image at all) as a map + letting the user calibrate it by marking a few known points while hiking ? This would allow one to take a picture of a map "in the field", for example, at the hiking trail entry, and use it straight away as a map.

PS: This is not a request, just a wish, a feature that would be really nice to have

On my Nokia 6600 phone I had a few years ago, I had a program that was able to do this. So it is absolutely possible.

hi,
  interesting idea but to be true - this feature use 1 user from 1000, maybe once per year . So sorry, it's too much work for very little benefit ...

[InfX]

Its not just possible, a program called "GPSTuner" on WM did that. I've only seen it long ago, though. But yea, as i already mentioned, it's just a wish. Kinda sounds like a bit too much work to implement, really. Still, isn't this directory called a "wishlist" ?  

[Menion]

yes it is But not all wishes may come true, and this is one that will not.

Long time ago, I used a similar product on Windows Mobile (don't remember the name) with a really nice function which enable to transform an image stored on the phone into a maps. It was only necessary to give 2 or 3 coordinates on the image and then I was able to use the map directly on the phone.
It it very useful for example when you're visiting a natural park with a map at the office, or when you want to use an old paper map without installing software on a computer.

I think it has been discussed before.

Anyway, +1 from me :-)

hey guys are you kidding this request was here once, as marlar say. I cannot find it now .. ah here viewtopic.php?f=13&t=377&hilit=map+camera

There's a couple apps on the android market that claim to do the map calibration on-phone from a picture. Some free ones even:

Probably don't have all the features of locus, but if you want this one particular thing it might be good.

[Ferretty]

Did you check if any of those is capable of exporting the calibrated map for use with Locus? From the descriptions, it does not look like

+1 from me.  Really need to scan an aviation chart and set my coorinates on it then export to Locus readable format

Maprika  works really well for this.  You can calibrate directly in the app against Google Maps.  I was at a large park here a few months ago, wife and kid were in line for something so I got on the tablet, googled a map, loaded up Maprika, spent about 10 minutes putting matching points and then I had a nice geo-calibrated map to use for the park.

Maprika really worky well - thx for this info.
Question: how to import calibrated map into Locus?

Question: how to import calibrated map into Locus?

Good question!

I've also a lot of self-calibrated maps.

I tried scanned maps with locus, but most of then use custom datum and defined tm projection. When used with locus as tared map i've got wrong position. When used custom wpts map work terribly - when scrolled wpts moves on their own, changing position on map. So until locus could use oziexplorer datums and projections i'm using androzic (tb is nice, but need prepared maps).
