Hello,
This week I was making a tourist map of sicily, when I remembered that in all these years I've made several maps of the island. I always make my maps from zero, I never "recycle" a map, so once finished I look in my huge hard disks and thousand made maps...
I think that it may be interesting for this forum to see the same territory with different treatment, so I selected some maps to post.
Think that some of these maps have more than 5 years...
best regards,

Fernando,

AS always, I love the look of your maps. Great to see the changes over time. I'm curious about your source or process for the first map in this list (from the top). Anything you can share?

Hello Dorn
Well, the first map is the most recent one. For instance its just finishd for the Spain version of National Geographic.
The map is make up with SRTM DEM Data rendered in Visual Nature Studio and a Landsat Satellite image as overlay.
Its not just a rendered map with a 2Xor 3X vertical exageration, its rendered with 1X + 2X + 4X + 6X exagerations merged in photoshop with a masking technique, so the Etna and sorroundings appears 6X, but lower areas are 1X or 2X, depending, just and only, on the visual appearance (no thumb rule here).
This is required since Sicily's relief has a lot of little mountains that results in a "noisy" terrain when viewed in 3D with huge exageration factors, but, with little exageration, makes Etna no significant at all. So... I want the Etna and north mountains be distinguised... the trick is just to "eliminate" low mountains and exagerate the Volcano....
The texture is a mix of images from Landsat, shaded relief, slope shaded relief and green - brown hipsometry.
As always, and as a last touch... a very very light Haze effect in the background to force a 3D perception.
best regards.

Your work is an inspiration. Thanks for sharing.

Fantastic, thanks for posting these!

Thank you very much. I hope to post some more maps this week

That third one (with Sicilia in upper left corner) is really great! Well, they all are, but I particularly like that one. Is there some sort of subtle halo around the major waterbody names or is that my eyes playing tricks on me? Also, what did you do to get such a smooth and subtle slight bathymetric shading (i.e. how did you get the shallow areas to look so good)?

Hello grethen
You are right, The main water features have a light halo to make the "integrate" more smoothly with the sea so they dont float over the background. A very light halo. Your eyes are correct ;-)
I apply an halo effect some times in maps to integrate and make text more readable. Both in water bodies and in earth zones. It's a more light effect than stroking the texts with a white stroke, but not always possible to use it.
The bathymetric effect was done using Btopo bathymetry dem as a source and, as this dem is a 1 km resolution dem with lots of "noise" , it was smoothed with surfer. Then the image was retouched in photoshop to smooth it and add some inner glow effects to the coasts.
Best regards

Hi Fernando,
I've just found the CartoTalk site. I'm studying for a doctorate at Edinburgh University and have been trying to locate a bathymetric map of the east coast of Sicily. 5m contours would be great but would settle for less. Could you direct me to a site that would show me this information?
thanks

Have a look at: http://www.naturalearthdata.com/

I have also listed a bunch of sources for free and open GIS data on my website here: http://www.spatialan...data-resources/

You will be hard-pressed to find 5m resolution bathymetry for free.

Good luck!

Hi Graham,
As Michael said, I think it may be hard to find for free (for instnce even paying) Bathymetric datawith 5m contours. Perhaps in some Italian institution they may have it. If not in digital format, at least some charts that may be digitized.
The Sicily map is at a scale in which with ETOPO5 or BTOPO30 is enough to represent features (look for them, they are frrely available)
I hope I have been usefull.
