Penzance to Plymouth

I have a dem map for the section of Penzance to Plymouth in the UK that I am working on. It covers the main line through Cornwall with branches to St Ives and Falmouth. I have the original map without track or scenery on it. I have up loaded it to ‘yousendit’ for someone else. It is available for 99 downloads over the next six days
The map size is 110mgs… but comes zipped. You will also need to download the hog files from DLS if you do not already have them.

What exactly does "It is available for 99 downloads over the next six days" mean? I honestly never heard the phrase before.
 
Would have thought it better to start over using the Hi-Res UK DEM that can be found in the UKTS library and up to date Transdem methods of adding mapping and exporting into Trainz.

Besides whichever way you look at it, an 80 mile route plus all the branches would be a huge undertaking and take many months, if not a couple of years to complete.

I'm assuming some sort of Cornish route was created at some point as there are assets such as stations (Liskeard, Menheniot etc.) on the DLS.

The 50m UK DEMs, called Land-Form Panorama®, can be downloaded from the Ordance Survey Open Data site, no need to go elsewhere. The reason why a copy exists at UKTS seems to be their favourite sim game which appears to be a bit picky with DEM file formats.

As geophil said the UK DEMs are available from OS Open Data for free, zip file for the UK is only 535,707 KB (approx !). You will need to have a program like Transdem (well worth the money) to convert the DEM into Trainz baseboards.

But be aware that at this scale the DEMs are great for general use but if you want to be accurate about trackbed levels especially in hilly areas then the 50m DEMS may be out by several metres. 5m and 10m DEMS are available, not sure about the coverage, but you will need to be seriously rich to afford them commercially. They are available ' free ' through http://www.landmap.ac.uk/ but only to subscribing academic institutions and you will be very lucky to get access to the relevant systems (I wish I could!).

I think your best bet would be to wait for "marky7890" to release his route which looks first class.
 
Well itareus, I might as well wait.


But in an unrelated story, is it possible to convert Microsoft Train Simulator models into Trainz models?
 
The DEM I have from UKTS shows up as 20m resolution in Transdem.
Sorry for being off-topic again. :eek:

Whoever provided the UKTS Land-form Panorama download, he apparently did the the right thing: re-sample the data before converting to a file format RS/RW understood. As far as I know RS only suported SRTM .hgt and a later version of RW added ASTER GDEM .tif. Both are Plate Carrée pseudo projections, i.e. lat/long in a Cartesian raster. (GeoTIFF would be much more flexible but RW wouldn't know how do deal with it then.) The original Land-form Panorama is in OSGB36 projection.

Each geo data conversion from one projection to another is a lossy one. To minimize loss, you can increase resolution. Presumably, 50m Land-form Panorama became 1 arc sec which translates to about 20 x 30 m for the UK. However, nominal resolution is not physical resolution.

Now, both Trainz/TransDEM and RS/RW apply UTM coordinates internally, another lossy conversion. With TransDEM, though, you convert OSGB36 to UTM directly, without taking the Plate-Carrée detour.

In any case, since SRTM is orbital and Land-form Panorama is terrestrial you will gain from that fact alone. You will notice the difference for forests, built-up areas etc. So using the O/S data in place of SRTM is always recommended.
 
Marky has been making this end of the route as far as Plymouth I think and has been hard at work for a few years now and my concern is that it has grown far too large to upload to the DS, which is why I upload my sections from Padding/ Reading; Reading/Westbury and at the moment working on Westbury/Taunton. Even these sections run out as quite large files so be aware that creating these routes sounds like a good idea they are a project that will take a considerably amount of your time, if not all of your spare time and go on for several years. My sections have taken about 6 years so far but that includes making a lot of assets for the third section which is about 1/3 done.

I use DEMs made for me by a kind soul who's name will remain a secret and I am ever grateful for the time and effort they put in, which is why I keep plugging away. But levels are way our in hilly areas so trackbed and land heights need a lot of adjustment. I do this in conjunction with OS maps because they have the correct heights on the contour lines - yes, even a blonde can read OS maps.. ha ha.

My route sections are made in 2004 and now I cannot upload any more to the DS. However, and with help from Robin Hoods I now have a way of uploading to the TrainzProRoutes Download Depot. Uploads there are limited to 10 megabytes and my 3rd sections is way, way past that so I had given up hope of ever getting it anywhere until Robin came to the rescue. Now I am back on it working hard making a whole mass of assets and plonking them on. But I somehow feel cheated when adding an asset I made, it takes a couple of seconds to add but took maybe a day to make...
