After I introduced myself shortly I like to show here a bathymetric map that I made from the axis of the southern Mid-Atlantic Ridge at 5°S after the most recent workflow I use. The map mainly shows the graben in the rift axis with a so-called axial dome in the middle. This is basically a large active volcano with relatively smooth surface (due to large lava sheet flows). The axial dome shown in the map hosts at least three hydrothermal fields with venting temperatures up to >400°C (the so-called Turtle Pits, Comfortless Cove and Red Lion fields). I did not included any text in the map yet because I first like to show the bathymetry and explain what I did so far:
1. Fledermaus Pro 7.4:
Create a 40m cell size grid and export as ArcView asc-file
2. TTS 1.3:
Import asc-grid and render with 'Elevation - Texture' at 80, 'Vertical enhancement' at 4.5, 'Custom Palette', 'Color distribution' at equal-relative
3. Global Mapper 15.1:
Layer 1: asc Grid - Daylight shader (color white, translucency 40%)
Layer 2: asc grid Slope shader (max slope 40°, translucency 65%, hillshading disabled, blend mode: multiply)
Layer 3: TTS GeoTiff (Transparency set on black, 100% opaque, blend mode: multiply, Texture map: enabled)
export as GeoTIFF with background (void) pixels transparent
4. Photoshop CS6 (with Geographic Imager PlugIn):
simple correction on "Levels" and some subtile tuning with "Highlights/Shadows" and "Lightness/Contrast" to make the colors a bit more vital again and get rid of too dark shadows.
5. Surfer 12:
Final map design (so far). Since TTS don´t exports a color bar I made one afterwards in Surfer (by having a grid file invisible laying as 'image map' in the background). The scale is made manually because Surfer can´t create a metric scale if I use degrees as unit (at least I did not find out yet).
I´m curious about your opinions so far and what may is good or not so good :-)
