Topographical maps & where to get them
« on: 04 July 2007, 11:42:27 AM »
Hi all, ive been searching high and low on the net for a good topographical map of Australia and particularly Victoria.

Im not so desperate to buy one, but i was really hoping to find something on line.

Now im not even sure if topography is even the right word. Im trying to find a map of Australias Land elevations, and shows ranges and mountains etc, their heights above sea level etc for two reasons, 1st and most important, I want to look at the way land features trigger thunderstorms, I understand how this can happen, but id like to look at individual instances, and know the details of the land feature thats doing the triggering. I may even be able to predict where somthing of intrest may  occur and video it, including a timelapse.

The second reason, is my G/F has never seen snow. Right now we do not have the money to go to any of the national parks or what ever they are, where you have to pay to enter and pay for a lift to go higher, then if your gonna do that you may as well hire some ski's or a snow board, and if your gonna drive all that way you should prolly stay for a few days. What im getting at is that it will be quite a few years before we are in a position to fork out those sort of $$$.

So i figured If I could know where there are various mountains and ranges and their elevations and I could find out where there wilil be snow low enough to cover the tops, I could then show Kirsty snow with out needing to drive too far, like macedon and a couple of other places maybe the rialto lol. We live near Geelong. So if any one could provide a link to a site that has maps that show these sorts of land features I would be most greatfull.

Try having a look around this site to see what is available online or maps for purchase:

http://www.land.vic.gov.au/

The equivalent NSW site has a fantastic online mapping tool, though it requires a browser plug-in. You can overlay aerial photos and all sorts of maps including topography.

Believe it or not, Google Earth isn't a bad tool for identifying large scale topographic features and relationships. Just be sure to exaggerate the elevation factor in the options menu, as the proper ratio is not the most telling when looking at sizable regions. If you search around, you'll find that some weather charts are also able to overlaid. That may help you on your hunt for interaction.

Geoscience Australia also publish topographic maps at a variety of scales. Best of all, they're free online:

Hope that helps a little.

Cheers

Good reply Hung Lo Phat, I have used google earth ages ago when it was a beta product, but I had no idea you could get elevation info fom it, should have guessed though Ive heard about all sorts of stuff you can do with it.

Prob is, I dont have Broad band, and im almost certain Google earth dont work with Dial Up. Ill have Broad band by spring. But thats then this is now. Ive actuallty looked around Geoscience australia before, and I could zoom in and out of the map i was looking at, but there were things like buttons that had no explanations to what they did, the buttons that did have explanantions didnt work or didnt apear to do anything in the way off adding or removing layers, some did get removed, but it wouldnt add any layers like elevation, it did how ever add some thing could horizontal control points But I have no idea what theydo or represent. The map its self was kind of cartoon like, and seemed a little amateurish. For all I know the map I was looking at was for kids, and I should have been looking at somthing else.

So Im checking out the link you gave me Hung Lo Phat, I dont think I accesed the map thourgh that exact page, so Ill post another message when I find out.

I was thinking I wouldnt have any probs finding one of the Maps that is usually black & white, and is made up rings, that show land features and their elevations. I guess these rings look somthing similar to Isobars on a synoptic chart. I know Ive seen these maps before, i cant remeber where when or why. Maybe Id best go to a map shop, but maps usually cost a small fortune. Rightly so though, you think about what would go into making such a map, and then selling only a microscopic fraction of road maps sold, I guess they neeed to be expensive or they'll never get made again.

Ok when I do everything it seems you can do it keeps coming back with "no results found" It doesnt mnatter if I click "define area of intrest" and use the map of australia to define an area, or if I type in the field "victoria" top search for a map it keeps coming back with no results. I dont know if they are related but at the very bottom of the link you gave me it says this: "Please note: These downloads are intended for use in Geographic Information Systems [GIS], Computer Aided Design [CAD] or Image Processing Systems. You will need specialist software to view and manipulate the data." Just above that theres a toll free number you can call, I might give them a call to see if I cant get some help. I think I best be patient and wait for when I get Broad Band and just use google earth. Hopefully the elevation layers are acurate and good.
