InternetSAR is a great accomplishment. I applaud all involved in setting up the website!!!
I read about InternetSAR in today's Avflash newsletter. I just signed up this morning. I am not very familar with Google Earth, so please excuse my ignorance. I downloaded several images for the Ron Boychuk search and all of them are very dark compared to the normal Google Earch image. Is there something I can do to lighten the search images to make it easier to distinguish details.
Here is an example
Thanks,
Jim

In the future we may have some ability to adjust the brightness and contrast of imagery, but right now I do not think it is within the capability of the software being used to process the imagery we are getting. The master images we work with are very different from standard graphics files and they are extremely large. Cuddly Bear, who is our imagery processing guru is using special software to crack the giant images into image sets consisting of small image tiles.
Eventually, we may end up writing our own image processing software and can look at adding this in as a capability (there just aren't many programs that can handle 2gb+ image files).

I am still building the imagery tutorial site. If anyone has any content they would like to contribute please send me a pm.
As of right now the site consists of the following sections:
About
History of Imagery Analysis
Imagery Analysis
Basics of Imagery Analysis
Map Reading 101
Satellites and Sensors
InternetSAR.org
Tests
Terminology
Tentative sections:
Terrain and Vegetation Analysis
If you believe I am missing anything of importance please let me know, and
if you want to contribute to any of these sections please contact me via pm.

Adjusting your screen to compensate for black or extremely dark inages.
I had this same problem when I started working in GE.
The problem is in the graphics controller on your individual computers and monitors.
I have a GE-Force2 MX 100/200 by NVidia. I am running Microsoft Windows XP-Pro. The graphics card drivers were installed automatically when I installed the MS-XP-Pro. MS simply used the "best-guess" default drivers when the installation was done.
To fix the problem I had to download new drivers for my graphics card so that the Brightness, Contrast, and GaMa settings could be adjusted.
If you are running Microsoft Windows operating system look in the control panel and find your graphics card. Try to find out if there are any brightness and gama controls. If the drivers do not present any controls you may have to download new drivers for your card.
Other operating systems like Linux or Apple should have the same capabilities but I can not guide you to these settings.
One disadvantage with the GE overlays is that in order to see the imagery my graphics settings are set so high that the rest of my screen apears nearly pure white and extremely bright. (Blinding, but it works).
Unfortunately as Ken says right now there is no way for InternetSAR programmers to manipulate the images or adjust the contrast.
I hope this helps.

At this moment, this programmer can't even get caught up on his email. 
In the past 24 hours we have gone from 40 members on InternetSAR.org to over 200 members with a new member signing up almost every minute. 
If anyone gets ANY error message from my server (e.g. it doesn't respond correctly), please let me know immediately via this forum or PM. This is our first real load test of InternetSAR.org and I do not know how it is going to respond. Let's hope it weathers the storm.

Please consider that these are media reports and not official, so until there is confirmation we are best advised to treat them as such.

" Boychuk departed from a Springbank, Alta., airstrip on Tuesday morning, and it is known that at 2 p.m. he refueled in Revelstoke. He was to continue on to Qualicum Beach via Salmon Arm, though he never checked in on the first leg of his journey.
Boychuk made the run routinely, and was reported missing by his son when he failed to show up at the Qualicum municipal airport at 8 p.m. His last known position was about 150 kilometres west of Salmon Arm, suggesting he may have skipped the scheduled stopover and continued on towards Vancouver Island. "

_______________________________________________________________
" 2nd Lieut. Alex Cadieux, a spokesman for the Comox 19 Wing, said "Boychuk’s last known radio transmission was from over Spence’s Bridge". "After that there was no more radio or radar contact," said Cadieux..."
_______________________________________________________________
" After leaving Alberta, Boychuk refueled in Revelstoke, B.C. He was scheduled to stop in Salmon Arm, B.C., before finishing his flight at Qualicum Bay on Vancouver Island.
When he didn't arrive his son reported him overdue on Tuesday evening. His last known position was about 150 kilometres west of Salmon Arm, suggesting that he may have skipped the scheduled stopover and continued on towards Vancouver Island. "
source; http://www.ctv.ca/servlet/ArticleNews/story/CTVNews/20071028/missing_plane_071028
_____________________________________________________________
Based on this information that has been reported and subject to further verification, Boychuk departed Revelstoke at 2 pm and the last radio transmission received from him was his position report over Spense Bridge. The distance from Revelstoke to Spense Bridge measures 148 statute miles on a magnetic heading of 250 degrees.
At an estimated ground speed of 110 mph, Boychuk was over Spense Bridge 1 hour and 25 minutes later or at 3:25 pm. (The time of the position report should be on record) From that point the straight line distance to Boychuk’s final destination is 154 statute miles on a magnetic heading of about 240 degrees.
At an estimated ground speed of 110 mph his arrival time at destination would be about 5 pm. However, it is unlikely he would fly that leg in a straight line because of the terrain. Following roads or valleys would have extended his estimated arrival time somewhat.
Based on these assumptions a viable search pattern would begin at Spense Bridge on an azimuth of about 235 degrees for 160 statute miles and an azimuth of 360 degrees for 160 statute miles. Within this fan, the most severe terrain is in the first 60 miles and the most unfriendly area to go down in. Within the fan of the first 60 miles, the most likely flight routes should be identified and searched thoroughly. In my opinion this is the area we should look at if the imagery is available.
Of course I have only looked at this for two days and the discovery of additional facts could change this theory.
Meanwhile, the imagery that has thus far been posted should be examined. I have been looking at those areas last night and this morning and see nothing to report. I suppose that searching this area is based on a premise that Boychuk turned his 172 about for some reason and was trying to return to Revelstoke.

Wow! I took a couple days off (really sick with a stomach thing/fever  ) and I come back and all kinds of things are happening! Ken is doing interviews and radio shows for the Boychuk search. Obviously, I missed the live version, but is the radio show archived, or at least a transcript available?
And now I'm confused with the split between the Fossett and Boychuk threads. Mixing them wouldn't have been that bad, we could have prefaced the subject header with either Fossett or Boychuk or generic, because we talk about things that might pertain to both searches or just searches in general. Where so we post about generic InternetSAR.org stuff. Is anyone still going to be posting to and reading the Fossett thread anymore? I'm so confused.  <dizzy and nursing some ginger ale and dry toast>
Also, I probably missed this, but do we have direct communication with the head of the Boychuk search team yet? If so, can we assume they have the most accurate information available?
Ken, I got your PM about doing the copywriting for the history and tutorial for the site but it looks like supersquint is still planning to do the tutorial part.
Last but not least, that's really great about the increase in membership.

No tutorial, just an example pic showing how hard it could be to make out a crashed plane, even from above.
Disregard blue colour in this image, Ron Boychuks airplane is overall tan colour, with stripes. See page 1 of this forum for pics of the actual plane that Ron Boychuk was flying. I repeat, the blue plane seen in this image is just an example of the sort of situation that small planes end up in on occasion.
1947 PA-16 in Chugiak Alaska. Occupants both survived.
I had originally wanted to do an image tutorial of things like this that were posted to the forum to put on InternetSAR.org, but I guess it's not as easy as I thought because of copyright issues.

That will teach you to get sick and take time off. 
First, the Fossett thread should be used for Fossett discussions and the Boychuk thread should be used for Boychuk discussions. The reason for splitting them off was to make life easier for new members who were joining to participate in the Boychuk search.
I am personally keeping a browser tab open to both threads and periodically refreshing them. I had to turn off the email notifications for new thread posts as my email was becoming almost unusable with all the email I'm suddenly getting.
We do have an official contact channel with the Boychuk team who is supplying us with imagery. We are working on getting more imagery as we would like to see more imagery to the west and at our current rate we will run out of imagery for the Boychuk search by early to the middle of next week. One problem will be is that if there isn't more imagery that had been taken at the same time the current imagery was taken, we will have to wait until spring for new imagery because they are buried under lots of snow and any crash site would also be buried.
If we run out of imagery for the Boychuk search, my suggestion would be for people to continue to work on our Fossett imagery. Hopefully we will get new imagery for one of these two searches before we totally run out of imagery.

The following information was provided to me by my contact at the Boychuk search team:
Quote:
I have not heard about additional images yet. I will keep trying to
get them, though.
.
You are right in that some news stories put Ron further west. However,
the area we are searching is one of the five search areas Ron's family
want to focus on. The other four areas are located west of this one.
.
Thank you very much!
