Recreating a cliff

[annber]

Hello,
Can I get some advice as to what would be,
1. the fastest way to make that cliff.
or
2. the best way to make that cliff.
I have a custom made mesh for that area, but the cliff does not show up at all.
I tried with sketchup, but it looks a bit geometric.
Thanks!!

Hey Annber, have you tryed this tool?

 

[annber]

Hi Marc.
Yes I did, that is how it looks. I was wondering if there was another quick way of doing one.

 

[Marc L]

well, the one yo have now is verry good already, and I don't know another way :/ just wait and see if someone else comes up

You could try to use a terrain flatten to make the cliff.

most games create 3d geometry for sharp cliffs. You could do something similar.

Hi Bernardo:

Indeed, you could make a 3D model in Sketchup, import it to MCX, then export as a CVX vector sloped flatten to modify local terrain mesh.

Your workload could also be reduced by use of imported local terrain elevation data from DEMs or digitized contour maps.



Is this location ICAO: TISX "Alexander Hamilton Airport, Christiansted, St. Croix, USVI" ?

If so, there is high resolution LiDAR elevation data available one can use to make a detailed terrain mesh of USVI instead of a sloped flatten.

Hi Gary,
Yes, it is TISX. I am delayed on all developing at the moment because of computer issues, mainly a fried GPU a few weeks back. Got a loaner GPU, but all developing related software is painfully slow, every texture loading or editing takes minutes to load, etc. Still, I want to push forward as best I can until a new system is ready. I did create a detailed mesh using USGS data, but that was a year ago, and it just shows a slight hump there, nothing dramatic. The 3D terrain feature in Sketchup also shows a slight elevation difference.

I am very interested in getting to learn this method, specially for Cuba. I am currently also finishing Isla de la Juventud, ICAO MUSN, which is mostly flat, but next week I start developing the Varadero area which will require more detailed elevation data. If this method is relatively easy to learn however, I would love to use it on St. Croix as well.
Regards.

I can't wait to see Cuba Annber !!! it has beatiful beaches

You should be able to display this terrain detail using the above cited high resolution LiDAR elevation data.

Hi Gary,
Could you post a link to where I get the data? I went to the following link, but was not able to find it.

TNM Download v2

The TNM Download Client is built on modern web technologies and features a simplified approach to downloading products from The National Map.

Hi Bernardo:


Here's the source for the data cited / depicted in my posts above:

https://coast.noaa.gov/htdata/raster2/elevation/NOAA_USVI_DEM_2013_8390/


I suggest loading the TileIndex *.SHP file in a GIS application to decide which parts of the data set ...you wish to 'directly' download / use.


Otherwise, use NOAA Data Accesss Viewer for more efficient selection / download of the Elevation and Imagery for your area of interest:


https://coast.noaa.gov/dataviewer/#...5.3740999997,-7186908.3531,2087410.4072999991


Hope this helps a bit more.

You could download something like thisSketchUp 3D terrain plugin

To get something like this:

If you didn't want to do it the sextant/slide rule way.

Hi Bernardo:

A GIS application is required to utilize the above cited 1 Meter resolution terrain elevation data as either a FS terrain mesh or a 3D model.


If you do not wish to utilize the 1 Meter higher resolution terrain elevation data, and do not intend to provide a 1 Meter higher resolution terrain mesh, you can recommend that end users of your scenery download FreeMeshX 30 Meter resolution terrain mesh FSX / P3D BGLs:

http://ninetwopro.com/freemeshx/


The FreeMeshX 30 Meter resolution terrain mesh FSX / P3D BGLs will already be higher resolution than what is intended to be made by the
the plugin Rick linked to above.

Be aware that (payware) plugin involves inherent limitations in resolution of- and access to- source data:
