&lt;div&gt;== Saitek Pro Flight Rudder Pedals ==&lt;br /&gt;

The Saitek pedals are in a similar price range as the [[ChProPedals| CH Pro Pedals]].&lt;br /&gt;

&lt;br /&gt;
(the shoe in the picturer gives you a hint about the size)&lt;br /&gt;
&lt;br /&gt;
The pedals center themselves, but the spring loading is not very strong. The large&lt;br /&gt;
knob in the middle can be used dampen the movement. In the maximum setting it feels&lt;br /&gt;
as if one had to move a lot of machinery.&lt;br /&gt;
&lt;br /&gt;
The pedals work flawlessly under Linux. They have three axes: one for the&lt;br /&gt;
use as rudders, and one for each pedal - you can push them down like an acccelerator&lt;br /&gt;
or a brake. The sensitivity is not too high.&lt;br /&gt;

In the SilentWings forum, there have been complaints about the spring&lt;br /&gt;

Some people have modified their CH pedals to get better results.&lt;br /&gt;

&lt;div&gt;Bew discovered gliding not long ago during a vacation in the Rhoen. Unfortunately,&lt;br /&gt;
Germany interprets the ICAO medical requirements in the strictest possible sense.&lt;br /&gt;
&lt;br /&gt;
His eyesight would allow him to legally drive a 1.5t 1000hp Bugatti Veyron at&lt;br /&gt;
top speed (~400 km/h) over the Autobahn in the night. In a 0,5t plane&lt;br /&gt;
at 200 km/h he would be a threat to public safety..&lt;br /&gt;
&lt;br /&gt;
If he isn&#039;t trying to substitute real flying lessons with googling for&lt;br /&gt;
flight manuals and practicing in Silent Wings, he develops software&lt;br /&gt;
and does consulting at a telecommunications company.&lt;br /&gt;
&lt;br /&gt;
Rumour says, that the ICAO medical requirements will be lowered to more&lt;br /&gt;
reasonable levels. There&#039;s still hope..&lt;/div&gt;</summary>

&lt;hr /&gt;
&lt;div&gt;There are a few things you can do if you like to use special hardware with Silent Wings:&lt;br /&gt;
&lt;br /&gt;
* [[NMEA format|Connect your PDA]] to the serial port on your PC (or use a USB-to-serial adapter), and use PDA soaring software like in a real glider.&lt;br /&gt;
* Use the [[NMEA format|special serial data string format]] to get a high-speed output of the aircraft state, and use these data for your own projects, like driving instruments or driving a full-motion cockpit.&lt;br /&gt;
* Create your own simulator cockpit, and create your own controls based on USB joysticks. Cheap USB joysticks can be disassebled and the internals used for custom-built sticks, pedals and other controls.&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;
People share their experiences about joysticks and pedals, and how they work with Silent Wings&lt;br /&gt;
* [[Joysticks]]&lt;br /&gt;
* [[Pedals]]&lt;/div&gt;</summary>

&lt;div&gt;=== Cloud Removal ===&lt;br /&gt;
&lt;br /&gt;
Free satellite imagery often contains a lot of clouds. Removing them by hand with&lt;br /&gt;
the Clone Tool of an image manipulation program is a tiresome task.&lt;br /&gt;
&lt;br /&gt;
Fortunately, there are better tools available.&lt;br /&gt;
[http://www.logarithmic.net/pfh/resynthesizer Resynthesizer] is an amazing plug-in&lt;br /&gt;
for [http://gimp.org Gimp], which makes removing objects from pictures a lot easier.&lt;br /&gt;
&lt;br /&gt;
# Select the clouds by color&lt;br /&gt;
# Grow the selection by a few pixels to eliminate pixels that belong to the cloud, but are too dark for &#039;select by color&#039;&lt;br /&gt;
# Use the &#039;Script-Fu -&amp;gt; Enhance -&amp;gt; Smart Remove&#039; tool&lt;br /&gt;
&lt;br /&gt;
Follow the links to see an example [http://beta.zooomr.com/photos/35232@Z01/762317 before]&lt;br /&gt;
and [http://beta.zooomr.com/photos/35232@Z01/762318 after] &#039;Smart Remove&#039;&lt;br /&gt;
&lt;br /&gt;
The clouds have gone but their shadows are still there. Roads suddenly end in a green&lt;br /&gt;
patch. Villages that were covered by clouds are overgrown by green woods and fields. Shadows&lt;br /&gt;
of no longer existing clouds still darken the area.&lt;br /&gt;
&lt;br /&gt;
Selecting by color has the drawback that every area having a cloud-like color&lt;br /&gt;
will be removed. Alternatively, you can select clouds by hand. The selection does not&lt;br /&gt;
need to be accurate, but all details accidentally selected will vanish.&lt;br /&gt;
&lt;br /&gt;
Professional geographers use the LANDSAT infrared bands to distinguish between clouds&lt;br /&gt;
and white areas. This is called &#039;cloud detection using spectral features&#039;, which is &lt;br /&gt;
short for: if its white/greyish in the visible bands and darkish in infrared, it&#039;s a cloud.&lt;br /&gt;
With some refinement, clouds and snow can be separated. This might be useful for high mountain&lt;br /&gt;
areas.&lt;br /&gt;
&lt;br /&gt;
[[User:Bew|Bew]] is working on a tool to automatically detect clouds. You call the tool with LANDSAT&lt;br /&gt;
images of band 1, 2, 3, 5, and 6. The tool creates a black and white image containing just&lt;br /&gt;
the clouds as black fields. You can import this image as a layer and simply select all black fields.&lt;br /&gt;
With this selection, call the &#039;Smart Remove&#039;-tool after having changed to the layer containing&lt;br /&gt;
your pan-sharpened LANDSAT image. The tool is not ready for public use yet.&lt;br /&gt;

The clouds have gone but their shadows are still there. Roads suddenly end in a green&lt;br /&gt;
patch. Villages that were covered by clouds are overgrown by green woods and fields.&lt;br /&gt;
&lt;br /&gt;
Selecting by color has the drawback that every area having a cloud-like color&lt;br /&gt;
will be removed. Alternatively, you can select clouds by hand. The selection does not&lt;br /&gt;
need to be accurate, but all details accidentally selected will vanish.&lt;br /&gt;
&lt;br /&gt;
Professional geographers use the LANDSAT infrared bands to distinguish between clouds&lt;br /&gt;
and white areas. This is called &#039;cloud detection using spectral features&#039;, which is &lt;br /&gt;
scientific for: if its white/greyish in the visible bands and darkish in infrared, it&#039;s a cloud.&lt;br /&gt;
With some refinement, clouds and snow can be separated. This might be useful for high mountain&lt;br /&gt;
areas.&lt;br /&gt;
&lt;br /&gt;
[[User:Bew|Bew]] is working on a tool to automatically detect clouds. You call the tool with LANDSAT&lt;br /&gt;
images of band 1, 2, 3, 5, and 6. The tool creates a black and white image containing just&lt;br /&gt;
clouds as black fields. You can import this image as a layer and simply select all black fields.&lt;br /&gt;
With this selection, you can call the &#039;Smart Remove&#039;-tool after changing to the layer containing&lt;br /&gt;
your pan-sharpened LANDSAT image. The tool is not ready for public use yet.&lt;br /&gt;
