• Which the release of FS2020 we see an explosition of activity on the forun and of course we are very happy to see this. But having all questions about FS2020 in one forum becomes a bit messy. So therefore we would like to ask you all to use the following guidelines when posting your questions:

    • Tag FS2020 specific questions with the MSFS2020 tag.
    • Questions about making 3D assets can be posted in the 3D asset design forum. Either post them in the subforum of the modelling tool you use or in the general forum if they are general.
    • Questions about aircraft design can be posted in the Aircraft design forum
    • Questions about airport design can be posted in the FS2020 airport design forum. Once airport development tools have been updated for FS2020 you can post tool speciifc questions in the subforums of those tools as well of course.
    • Questions about terrain design can be posted in the FS2020 terrain design forum.
    • Questions about SimConnect can be posted in the SimConnect forum.

    Any other question that is not specific to an aspect of development or tool can be posted in the General chat forum.

    By following these guidelines we make sure that the forums remain easy to read for everybody and also that the right people can find your post to answer it.

good initiative!

One of my favorite site for many years, since it not only includes links to all sorts of free data and tools but also tutorials and (political) background information regarding those sources: http://www.terrainmap.com/

US public domain orthoimagery and terrain data at http://seamless.usgs.gov/

Canadian public domain orthoimagery, vector data and terrain data at http://www.geobase.ca/ and http://www.geogratis.gc.ca/

Jonathan de Ferranti's enhanced Shuttle Radar Terrain (SRTM) data: http://www.viewfinderpanoramas.org/dem3.html

Cheers, Holger

CGIAR maintains a set of 5x5 degree tiles of reworked SRTM 90 meter DEMs

These large tiles incorporate some of Jonathan de Ferranti's improvements.

Another world dem source:

GMTED

You could also use it to check/fill ASTER data. It is actually several sets of data. "breakline" was created to preserve water channels and hill ridges. It comes in different resolutions. 7.5 arc second would be OK for an LOD7 mesh.

Commercial Higher resolution Digital Elevation Model (aka "DEM") source data: :idea:


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: :scratchch

"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

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
Global homogeneity
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!

So if you spend $100,000's of dollars to launch a satellite, then another $4,000 to generate the imaging, process them to format, and then prepare it for use, you shouldnt be allowed to charge for it?
They invest a lot of money to make those maps, its not cheap. Think, you are making money on their investment and work while they get nothing because you want it for free. Wouldnt seem fair to me. You have to spend money to make money, ask any businessman, thats the basic model you have to know when getting into a business. Investment is the beginning.

Note: This is not an attack or demeaning state, it is meant to illustrate the purpose of charging you to use it commercially.

Update:
Further reading I misunderstood the comment. To be honest, if you want to use it commercially, then dont buy from those who wont allow a commercial product to be created with it. You can also try to contact them and request, in writing, permission to use in a commercial product that is geared to a limited community, that probably wont generate more than a set amount of money over a given time. If they see no loss in it or a supergain on your part, then they will probably allow it.

This type of license is the most common.

In general, you will require a different (expensive) license to use in a package.

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:

http://www.mastersketchup.com/why-google-doesnt-need-sketchup-anymore/

http://www.gatewing.com/

http://vimeo.com/40452792



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 ! :idea:

Only problem is we want airports...with planes taking off and landing in the path of the x100....:)

And a Gatewing is worth about $50k ... apparently.

That's quite a bit of WV2 60cm imagery.
