Author Topic: TF Pro 3.12 - How do I get elevations to show?? (Read 11665 times)

derelict · « **on:** July 31, 2007, 09:55:46 PM »

I've registered TF Pro, and am using V3.12. I've imported tracks and waypoints (from my Garmin GPS60) for a recent trip, and it is displaying properly in the program. However, there isn't any display of elevations anywhere, is this correct?? The track list shows elevation for each of the tracks, but I don't see how to display this data on the main screen. Could someone advise me on this??

Hi,

What do you mean by 'display this data on the main screen'?

Are there no climbing / descending stats on the track listed in the active log?

Or is there no elevation shading on the track? If this is the case, it's probably just because elevation shading is turned off (there's a toggle on the toolbar for it).

How does the track look when you profile it?

The elevation shading there, and profile works fine. The problem with shading is that it doesn't actually show tell me what the elevation is at any given point.

What I actually want is for the window to show the current elevation wherever I point, like GoogleEarth does. You already show latitude and longitude in real-time, as I move the cursor. I think the ground elevation should show as well, then I'd get complete information on the location that I was pointing at.

As I'm typing this, I now realize that this has *nothing* to do with my track data, this is general map information. I wonder where elevation information on the terrain comes from??

OK, thanks for the clarification. You are right that TopoFusion doesn't give you elevation at any mouse location.

The elevation data either comes from the GPS track itself, or from the NASA server (for 3D views).

Each time you do a 3D view the program downloads all the elevation data for the current view. So it would require an http request every time the mouse is moved (not feasible, in other words).

In the future we hope to be caching 3D data locally, like GE does, and then we'd be able to get the elevation at the mouse.

Another thing we can do right now is give a right click option to simply request the elevation at a point clicked on it. I'd like to see this feature in the interim, and will add it "todo."

Thanks.

Well, if it's okay (since I'm a paying user), I'd like to take the moment to encourage you to put the caching on your todo list!! Without it, TPF alone doesn't work for me, I'm having to swap back and forth between TFP and GE to get all the information that I need (and I'm having problems as well, importing data from TFP to GE, which is a separate topic for later!!)

I use that capability to plan routes where I'm going to hike, by scanning which routes are steeper or shallower paths. It also helps me just visualize the terrain that I was travelling through!!

It seems to me that you *must* already have the elevation data available, in order to display the 3D view!! It's clearly an accurate 3D representation of the scene (VERY accurate, judging from the various tests I've already given it!!)... so it should be available for displaying as well??

(begbegbegbegbegbeg!!!)

Absolutely, your encouragement is encouraged!

I forgot to mention this - when you are in 3D mode you can get the elevation at arbitrary points.

As you hold down the right mouse button (to pan the map around, or move the blue 'center' circle around, if you want to think about it that way) the elevation at the blue sphere is displayed in the status bar (lower left corner of the TF window).

The 3D caching is definitely on the list, but it is a major project that will take some serious coding. Needs to be done, though.

What problems are you having with GE<->TF? Some issues reading .kml files have been fixed in v3.14, which I just released about 2 minutes ago.

Thanks.

Actually, I think I'll start a separate thread for my TFP => GE issues, so the discussion will be evident to others!!

Thanks for your prompt responses!!

One of the things that I want to be able to do is edit elevation data. Let's say I have a trackpoint with Lat/Lon/Elev and I am displaying the profile. I'd like to select that trackpoint and delete it in the profile view because that's where I can see the problem.

Hmm, selecting a precise point from the profile is a little tricky.

One thing you could do is "find" that point using the profile (2d location is displayed on the map as you move the mouse over.

Another alternative is to open up the file properties dialog, and hit the "show tracks" dialog to fill in the track list. If you sort by elevation you can quite easily find outliers and delete them from there (right click on a particular track point to delete it).

I can think about how to do this from the profile window, though...
