Commercial Higher resolution Digital Elevation Model (aka "DEM") source data:
Intermap® - NEXTMap Digital Elevation Models (DEMs)
This low-altitude IFSAR / hybrid multi-source data can achieve approximately a 5 Meter output gridding after processing for use in FS):
Ex: licensed NEXTMap data used by FranceVFR, VFR Photographic Scenery Generation X mesh, FS Dreamscapes NEXTMap ProMesh / Ultimate VFR products and/or FSGenesis etc.
A very promising site to watch for availability beginning in 2014:
"TanDEM-X Global Digital Elevation Model
Global Coverage - Unique Accuracy - Unprecedented Quality
TerraSAR-X and TanDEM-X radar satellites in space
The TanDEM-X mission will generate a global Digital Elevation Model (DEM) of unprecedented quality, accuracy, and coverage.
This homogenous elevation model will be available for the Earth’s entire land surface, i.e. 150 million square kilometres in 2014.
Unique Quality Features
TanDEM-X DEM Teide, Teneriffe
TanDEM-X Digital Elevation Model of Teide Volcano on Teneriffe Island, Spain © DLR
The accuracy of this global DEM will surpass that of any satellite-based elevation model available today and have the following unique feature:
Vertical accuracy: 2m (relative) / 10m (absolute)
12m x 12m raster
Highly consistent dataset thanks to data collection within 2.5 years only
No ground control information needed thanks to high geometric precision of sensors
Final manual editing secures international quality standards"
great idea, but have u read the licensing fine print? those mongrels wont allow your images to br includee in commercial packages fron what i read in their purchase agreement. bloody ridiculous if u ask me...its a damn paid resource. one should be allowed to incorporate it in commercial packages!
I encountered this interesting info today while chasing some links about use of Sketchup for scenery creation.
Google has sold Sketchup to Trimble, and Trimble has developed some amazing software and hardware tools to allow creation of ones own high-resolution GIS data for both aerial imagery and elevation via digitally-programmed low-altitude flight grids with very small radio-controlled aircraft:
Hopefully this may prove to be an affordable alternative to costly licensing for use of (all too often ...poor quality) aerial imagery and/or elevation data by allowing individuals and/or consortium groups to generate their own higher-quality GIS resources.
Perhaps this technology may also prove to be accessible to the FS development community !
