Hey guys

Yes!This is exactly what I wished for. If we can agree on a certain Icon "Pin Placemark" for each instance, say a RED pin for "Security risk" or "Don't camp here spots", Yellow for all the peaks, Green for passes, Pink for caves,etc. it would be easy to understand and read.

The only problem I'm not sure how to overcome is, how can we all collaborate on one map? If this is not possible, everyone will have to send their
way-points to someone who can compose it on one map. I would volunteer myself for this, except I'll have to figure out exactly how to import en export all the info to VE after I'm done and I'll probably take twice as long as someone who know what he is doing.

Here is a preliminary list of info needed:
1.Peaks
2.Passes
3.Caves
4.Huts
5.Don't camp here zones
6.Shepard kraals
7.Smuggler routes
8.Invasive flora (Pines,Black wattle,Dagga,etc) thx ST, good idea
9.Flooded river crossing points
10.?

In this way VE will be able to compose a comprehensive overview of the berg and share this info with authorities to sort out security and Invasive flora. We'll then be the "recces" of the berg.

Thx

@Jon & Boerkie

Yes that would be correct. Each of us involved with the project can put together their gpx data set and then one person can get all the data together and produce one set. Any additional data themes can then be sent to the data custodian and it then gets added. I would like to suggest that Chris be the custodian of the data sets and the various willing members of the forum the info gatherers and inputters of the data points.

To make it easier for the custodian though, i think it would be best that the info is not sent to him piecemeal, rather if there is an idea for a theme, that it be added once it has been 100% completed and then a full data set is submitted. This would obviously be difficult for themes like pine trees and incidents as they could only be submitted once discovered, however there is already a lot of data on that anyhow.

It would also be good to be able to link images to the each of the data points, be it a pass, peak, cave or whatever.

If we can also add "Base camp" options, meaning B&B's,etc from where one can enter the berg, to the map/wiki it would also be great.

ST I like the idea of linking images to the points, awesome.

The other thing would be unmarked tent sites that have actually been used in or at the entry point to passes that can be used in emergency when you run out of steam or light. We did this in Cockade Pass last week, I will be putting a report and images together when i can get over this flu i picked up this week. My one hike a year in the Berg, when I am over here shooting work for clients.

Some sort of collaboration is possible with Google Maps, if you have a Google account. Unfortunately, for some odd reason SA is one of the last countries for which the new mapping tools are not available yet. I think this will come though, and this may be the way to go.

Bear in mind that all of the GPX file downloads available on this site can be opened with Google Earth and can be uploaded onto Google Maps. For that reason I'm a bit reluctant to have two versions of the same waypoint (especially caves, peaks and passes) which need to be maintained, unless the waypoint is used in a special way on this map (like comments and pictures).

While on the topic, the reason the GPX files are stored split up as they are is to handle updates easier (users have an easier time finding an updated item as well as new ones), as well as to handle data from different sources, for quality control, since the file is linked to your profile. This is useful since caves, peaks and passes do get erroneously marked and I put a lot of effort into ensuring the accuracy of my own data. It is also simply the history of how things were started on the site. I realise storing everything in one big GPX file does have advantages, but am not totally sold on it, since its so easy to combine them on your own computer. Am open to opinions and suggestions on this though.

A GPX file for the Pine Tree Project will be available soon, and any other category (like junctions and campsites) can be added. I just don't even really keep up with my own personal database which has plenty of these kinds of waypoints already.

Perhaps this should be narrowed down a little in scope as well as geographic area so that we can work out what we actually want and how we want to do it. Take Cathedral Peak area, for example, as a pilot project. Think about ways in which such a map offers a better advantage over simply opening a GPX file with Google Earth/Maps.

Stumbled across this site and it is a good visual version of the VE composed map.

I have been working on a Google Maps project which will serve as an example of how it could be done. Still need a few days to finish it off.

I think (with my experience of GIS) that what we are actually after is a geo-database. I have the software (open source of course) to put together such a geo-database, but it will take me a little bit of time to sort out a database of sorts. The suggestions made will provide a great baseline, but the future requirements will take some thinking through. The future requirements of any project are always the limitation, as it takes someone with a strategic mind to see what the future possibilities are.

If we could take a couple of days and all post here what the requirements are, I could chat with a couple of guys who have oodles more GIS experience than I do, and work out a way to put together a GIS database and serve this online via a Google earth interface... Intrepid, maybe you can send me what you have in your GM project, and I can see what I can unearth through the MDTP project etc....

Here is an example of what can be done on Google Maps:
maps.google.com/maps/ms?msid=214155639705749540351.0004a8326a56c4ca4979e&msa=0&ll=-29.012569,29.207282&spn=0.035654,0.066047

Once you click on the above link, zoom in a little and select the Terrain view for a topographic base map. This is the Organ Pipes / Thuthumi Pass area. You can see that it is possible to include routes, various waypoints and shapes. Click on the Rolands Cave and Thuthumi Pine Infestation markers and you will see that pictures appear in the pop-up bubbles. Click on Organ Pipes Pass and you will see links to the write-up and GPS data on this site. These are all examples of what can be done. Its effective but does have some limitations. The new map tools I mentioned earlier in this thread relate more to advanced features which are not totally necessary right now. Collaboration is possible (send me a PM with the email address associated with your Google account if you want access to edit and add to it). Response anyone?

@domsmooth: the KML file for this map can be downloaded at the above link.

@ Intrepid I have been experimenting as well and uploaded all my tracks waypoints etc onto a google map, but the one limitation I have come accross is taht it lists all the waypoints first and then all the track in multiple pages. It appears to only display what is on each page at a time, so you will be looking at all the waypoints starting with abc and nothing else, likewise when you page through,(which is quite slow, althouh there is a huge amount of info) to look at tracks, there are no waypoints.

I don't know if there is a way round, other than splitting into smaller area maps.

Your sample area is really neat having all the links to pics, and track downloads PINES!!!(get itchy bushknife hand) etc.
