Alright, I just put out version 3.75 Beta featuring a long sought feature... elevation caching!
Thanks to Lucian Plesea over at JPL, we now have rapid access to tiled DEM data. As you pan around in TopoFusion now, you'll automatically be downloading DEM data, so it'll be there if you want to go to 3D mode, or if you want to add elevation to your tracks.
Now 3D works offline, if you've got the data and in general it's a whole lot faster and easier to use. Gone are the days of getting "trouble contacting server" (due to overload) when switching to 3D data.
Also, I can't believe it took this long, but the "undo" command finally does a few things it should have back in version 1.05 or so.
Full list of changes:
3.75 – [4/30/09] (Beta)
Added local caching of DEM data
- DEM data is automatically downloaded as map is panned
- Fast downloads, using OnEarth’s tiled WMS
- Stored in maps.dat structure, download once, always have
- Elevation at cursor given in status bar
- Faster 3D model generation. Works offline.
- Automatically uses NED (30m) data inside US, 90 SRTM elsewhere in world
- Option for forcing SRTM available (useful for US border areas)
Climbing Analysis uses cached data
- Increased accuracy for elevation gain and “Add Elevation to Track”
Added box filtering to Climbing Analysis (selectable filter width)
Added “Training Center” preset to Climbing Analysis
Added option to turn off 3D transition animation to 3d Options
Fixed alignment errors when switching between (eg) topo and color aerial tiles
In 3d mode
Undo command now reverses the following actions:
- Deleted points
- Moved points
- Cut track
- Delete track
- “clear all” when drawing a track
- “clear all” when merging tracks
- “remove last segment” when merging tracks
- “remove last segment” when drawing a track
Fixed bug in realtime Multi Playback causing dots/names not to appear
Fixed problem with Australian Topos not downloading (due to server change)
Fixed lingering “download” tiles in both 2d and esp. 3d mode
