draw simple landscape

[Alexander Wolf]

Feature request by skoop from cloudy nights forum: Simple interface to draw personal obstruction "mask" to the landscape but above the horizont.
For example if there are buildings or huge tree.

Isn't this similar to this blueprint?

Yes, it is similar

The new polygonal landscape type is the requested landscape type. I think one of the benefits is that is really easy enough to write the azimuth/altitude lines manually into a horizon file, or even create/extract it from an instrument file (total station etc).

Alternatively, a web interface, clicking x/y values in a horizon (panorama) grid, is all we would need here. The values can be added via PHP to the HTML below the image, and then copy-pasted into the horizon file. (I have done such a thing before.)

Now, I want to see 25 "I desperately need this web interface" before implementing even this. Doing it interactively inside Stellarium may be done as an optional (GSoC?) plugin.

PHP is an overkill, I think it can be done in JavaScript. :)

I had started writing a landscape-editing app for the /utils directory,
similar to what we have for the locations list. I need to look at how far
it had gone.

Sorry, I indeed meant Javascript. It was late...

What I had done was finding pixel coordinates for scanned maps in a globe
texture mapping helper. Similar functionality could just print az/alt
coords over a coordinate grid. These data can go in a horizon.txt.

This is reasonably simple to make. Doing vertex edits interactively in
Stellarium is what I really consider overkill (cost/benefit - wise).

But entering these data manually is also no big deal, so I wonder if it's
needed at all. Matter of taste, as always.
