EVI2 vs NDVI

EVI2 vs. NDVI

EVI2 based on summer Landsat acquisitions (from 2009 to 2011, histomatched, only tiles that originally fall into UTM Z34N) covering Ellas (Greece)
NDVI based on summer Landsat acquisitions (from 2009 to 2011, histomatched, only tiles that originally fall into UTM Z34N) covering Ellas (Greece)

Map Swipe (g.gui.mapswipe)

Recent addition in GRASS 70: http://grasswiki.osgeo.org/wiki/WxGUI_Map_Swipe

The Greek island Mytilene (Lesvos): swiping a summer Landsat RGB (bands 7, 4 and 2) composite image and an unsupervised classification based on a bi-temporal NDVI image (summer and winter NDVI)

GRASS-Wiki content maintainance

Various issues

To list...

Upon the use of Templates =

True, content is the foremost essence. In order to ease off content reviewing and management, WikiMedia, upon which the GRASS-Wiki relies, has the Special Pages section. Still, there is a significant need for user input to control the content. Towards a better and easier maintainance mechanism, it might be useful to setup as much as possible Templates which can be used easily across the entire GRASS-Wiki to mark pages and notify readers.

For example, it is not always easy to discriminate between truely OutDated content or simply content that refers to an older version of GRASS. In this case, a notification indicating that the content refers to an older version of GRASS (be it GRASS 5.x) would be, perhaps, a smarter solution than simly marking the page as old. Alternatively, or in addition to a Template, a corresponding Category should be created.

There is, in my opinion, a natural need for some concrete, short, useful set of basic Templates. There are already several Templates. However, the influence in organising the content will be more effective, if the Templates adhere to a basic set of universal rules (think of appearance that invites to get involved) and delivers in a concrete way the "message" (think of short, rational, meaningful notification and/or explanations).

Towards this scope, I support the creation and collection of Templates to cover, if not all, at least the very basic needs to help tag the content.

GRASS-Wiki native colors

Should GRASS-Wiki pages wear GRASS' native colors?

Or else... ?

Some random example: light grey font-color (#dcdcdc), green border (#4da948)

Better typography

Review and possibly alter:

  • linespacing (between hierarchy elements!)
  • indentation of code blocks -- might improve readability
  • (non-code) text wrapping -- narrower body text column, easier to read
  • move ToC on the right, make it fixed! This will "save" some long pages!
  • move Categories right below the ToC -- also useful inside long pages

Elements

The very left column is like a Wiki's connection terminal -- it should look and act like that for the user. It should also clearly state GRASS-GIS' identity.

Better typography is not only about aesthetics. It's about readability and making things easier to study. The screenshot below speaks for itself. Hint: the ToC is always accessible, following the user's eyes!

The Table of Contents is a must have for page-content organisation and navigation. Can it be *always* accessible while not distracting the user from reading when not required? Yes, it can.

Distance between Sections

Seems to be the same, for some reason, anyhow, some lengthy GRASS-pages look overfilled/noisy!

The GRASS-Wiki Special Pages are nicely structured, easy to read. Is there, and what exactly, a formatting difference with the "dafault" GRASS-Wiki pages?
