About geo-localization of SP pictures

I suggest all pictures on this site should be geo-localized. Even if it's a huge work to update all the existing pictures, that will give sense and usefullness to the big amount of posted pictures.

It seems some SP users don't know how to localize pictures with google maps tool. New Google maps with altitude and relief helps a lot, but some summit names are wrong.

I simply suggest:

- update your own pictures as much as possible.

- be accurate when possible (localize the side of the mountain...)

- take care of SPv1 pictures, they got the localization of their attached mountain and that could have been a wrong localization

- to not give anymore "points" to pictures with default geo-localization values.

- To not vote 10 (but vote anyway) on a picture before having checked the geo-localization is accurate, be tolerant with panoramas where geo-localization could be about any part of the picture, or the view point.

What value does the lat/lon coordinates have for pictures? I don't see it. Take for example the link below which is displayed when you click on the coordinates for an image of Tower Peak.

Google Map of Tower Peak photos.

There are so many other photos close to the one I clicked on that they all melt together. What value does this have unless you are looking at an obscure peak with only a couple of photos...? Try this experiment with photos of any of the popular peaks and you'll have the same result.

1 / Yesterday, I tried to prepare a trip to a completely unknown place. I tried to use Summitpost pictures to have a look to that place. Only a few pictures were pointing the good site, so i lost time and still have no idea about how the mountains looks here arround...

2 / I found some interesting pictures about the region i want to go to. As the geolocalisation is not accurate, i don't know were to find what i saw on the picture, even on a map.

3 / Pictures are giving more informations than mountain pages, at least because a lot of mountains you can see on pictures have no page on SP. If you cannot attach a picture to a place on a map that won't help you.

4 / Your example: If all pictures taken during a peak trip are localized on the summit of the peak, that don't give a lot of info. At a big scale, all pictures should not be localized on the same place.

I completely disagree. I don't want exact turn by turn instructions of how to get to and up a peak, which is part of the reason I don't own a GPS. If people want to include the geocoordinates fine, but having them should not be a prereq for 10 stars. Furthermore I question the accuracy (and value) of retroactively labeling all of the photos on SP.

Topo maps are not enough to get an idea of where a scenery is. Anyway, I don't have all the world topo maps. Topo maps don't give the relation between localization and pictures you can find on SP.

It's easy for someone who takes a picture to geo-localize it. It's much more difficult for someone else looking at the picture, to search where it could be.

I agree with you, i don't use any GPS or instruction about mountains, unless for security reasons. But i usually use SP pictures to make my own plans. I was only taking about picture localization.

When i propose to geocoordinates pictures i only speak about the SP standard existing feature using Google maps.

Seems all pictures are localized on the summit, or 1 point

It would be much easier if every picture without GPS coordinates attached to a peak or other object with a position inheritates from this position.
It is the case when we create a picture by using the option "add picture" then "new", but already-existing pictures not.
I also always thought it would be genial if GPS-positionned objects on SP or MB would appear on Google Maps as we do a research on Google maps, the same way all sorts of other objects pop out when we make a map search on Google.
I don't know how to do it but if if so many other sites do, why not SP ?

This is why all photographs should be geo-referenced.

My "point" is that this would require a huge time. My idea would be that uncoordinated pictures inheritate from the coordinated objects to which they are attached.
For example :
- a pic of Triglav without coordinates gets the Triglav coordinates when attached to it
- a pic of Triglav with coordinates remains the same when attached to anything
It would save a lot of hassle

Another related topic on MBPost which will soon or late concern routes on SP, if not already...

To enter the proper coordinates when creating the image is the solution.

Your turn to forgive my lack of knowledge, but how the hell such line was created ? Someone increased gradually the coordinates for each peak ???
I don't see the connection with the initial topic... (despite it concerns coordinates)

Why shouldn't this be allowed ? I owe that all my pics related to the same mountain have the same GPS data, I'm not going to mess with each to put the exact location ! Fossana is right. I'd rather say that it is this SP feature (points next to each other) that is a nonsense. I dint know about it !

I recommend not voting unless the poster of the photo has a GPS chip embedded in his / her forehead, linked via Bluetooth to their digital camera ..
