Screenshot suggestions

Please put suggestions for screenshots to go onto the main website on this page. You can post URLs or upload images directly to the wiki.

Here is the new work-in-progress screenshots page:

• http://grass.itc.it/screenshots/

Note that all screenshots are to be licensed under the Creative Commons Attribution ShareAlike 2.5 License. Please leave your name as well so we can attribute correct credit.

• See here for help making an image on this page an instant thumbnail.
  (The syntax is [[Image:{name}|{width}px]])

• PNG images are lossless but can be very large for satellite images & photographs. Best format to use for things like menus with a lot of solid colors and where crispness counts.
  • To help save bandwidth, save your PNGs with compression setting of 9. Often you can reduce the file size significantly by reducing the pallet size to be big enough to hold just the colors used.
  • Running a program like pngcrush can compress it further.

• JPG images are lossy but can be much smaller for things like satellite images & photographs.
  • For quality save nearer to 85%, for size save nearer to 75%.

Image Processing

• clustering, segmentation
• sat img edge detection (Markus posted one recently)
• i.landsat.rgb trials [1]
• I remember a picture of a house and dock rendered in 3D from key GCPs in some sort of stereo photogrammetry project. Maybe from an abstract of talk from the GRASS conf. that took place in EU before the Thailand one (??)
• MODIS/Terra Surface Reflectance Daily L2G Global 500m - 8 Aug 2002 - true color image composite. Part of Europe as seen from MODIS/TERRA at 500m resolution (R1 G4 B3). New snow arrived in the Alps, floods in Austria, Czech Republic and Germany due to heavy rain (up to 300mm/24h in Eastern Europe). (screenshot Markus Neteler)
• MODIS NDVI/EVI images
• ASTER high resolution remote sensing - ships on the North Sea near Germany
• SRTM void filling with spline interpolation in GRASS GIS (screenshot Markus Neteler)
• LANDSAT TM7 visualizations of Venice, Trento (screenshots Markus Neteler)
• ? more ideas please ?

Remote Sensing and LIDAR

Satellite Data

MODIS, Quickbird, etc, I thought to put some sites/vector points stuff here too. Maybe split that out into its own category?

LIDAR and Sonar Data

• Lidar with NC OSGeo data set
• Jockey's Ridge
• gdalwarping of sidescan sonar track? - yes!

Sites (point) data

• where to put this? - eg NVIZ histograms

3D Visualization

• see Help with 3D

• NVIZ, r3.out.vtk, ... paraview from Sören
• MARS MOLA data ([2]) added to viz page

Cartography

(aim for publication quality)

• ps.map, nice PS,PNG driver renders
  • I do not know, if it suits, but this I got some time ago with pure ps.map [[3]]
• (TODO) Post ps.map instructions for the Norway geo map to the ps.map example page on the wiki.
• http://mpa.itc.it/markus/grass63/demos/psmap_rotcol.png (Hamish Bowman)
