Hi everybody!

I bought my Humminbird SI unit (798ci) last spring and have since been kind of addicted to it. This website among others has been very interesting and useful to me in finding more knowledge in Side Imaging and especially on Humminbird units. There are also those great and useful PC applications that make the hobby even more fun; HumViewer, SIView, YellowFin, HBSI Sonar Data File Converter etc. Many thanks to all developers!
Last fall after taking my boat out of the water there was more time to go through the SI recordings and looking for interesting points. (HumViewer was especially useful on that). However frequently when finding interesting objects, it came to my mind if this particular spot was on some other recording from another angle or maybe recorded closer. I also felt a need to know which part of lake is on SI recordings and which is not. (Not merely saved tracks but tracks with SI recording). With that idea I developed PC application which I call HumFinder.

With HumFinder one selects Folder, under which to search for Humminbird SI records, coordinates for target and range radius. Tracks containing SI recordings inside the range are then shown on local XY-graph and can also be shown on Google Earth. The track points are shown, in which SI beam “illuminates” the target along with information pertaining to that point. Record folder name and time values can then be used to look for SI image on that spot with HumViewer or other application. Searching for scanned or unscanned areas, one can set max target distance value high so larger area is shown.

I programmed HumFinder with National Instruments LabView programming language which is used extensively in instrumentation and measurement areas. In order to run HumFinder one needs to install LabView Runtime Engine 2009. It can be downloaded from
ftp://ftp.ni.com/support/labview/windows/runtime/9.0/
Download and run installation program: LVRTE90min.exe

LabView runtime can also be downloaded from
http://joule.ni.com/nidu/cds/view/p/lang/en/id/1406

I have tested HumFinder in the following environment:
Windows XP Professional SP2, SP3
Windows Vista Business
Humminbird 798ci SI, firmware 4.510
Google Earth v. 5.1.3533.1731

HumFinder has been tested only with North-Eastern hemisphere coordinates.
I recommend installing the LabView Runtime Engine before installing HumFinder. I also recommend using default folders with instalments. (I haven’t tested instalment to other folders).

With Windows Vista one needs to give read and write permissions to the file C:\Program Files\HumFinder\HumFinder.ini for the current user. Without write permission an error message is given when exiting and user interface settings are not saved.
There is no help file available at the moment, but short “Tip Script” is shown when user places cursor over a control.

Default Humminbird Folder and file names must used for the records i.e.
\RECORD\R00xxx.DAT
\RECORD\R00xxx\B002.IDX
\RECORD\R00xxx\B002.SON
\RECORD\R00xxx\B003.IDX
\RECORD\R00xxx\B003.SON
In other case the HumFinder won’t find those recordings.

In some cases in order to Google Earth to open, I have been forced to press “cancel” to Google Earths installation messages.

There is couple of screenshots as an attachment as well as HumFinder v. 1.0.0.1 installer program.

It would be nice if someone finds this application useful. Bug reports and development ideas are warmly welcomed.

Waiting for springtime and melting ice on lakes.

Regards,

Timo

wow, neat stuff. On your file names did you miss the B001 .IDX and the associated .SON. I think a recording makes all three. This program looks very interesting and will have to try it out. I know others will be ringing your door bell also. Thanks for the informaiton. chuck

Timo · « **Reply #2 on:** February 17, 2010, 04:31:37 PM »

Thanks Chuck,

Humfinder shows only tracks with side imaging, so B000.SON and B001.SON & B000.IDX and B001.IDX are not needed.

I was unable to send the HumFinder Installer file at the time , propably because of it's size ~13MB. Maybe Robert can help me with it.

Now it's bedtime, in half an hour it's midnight here in Finland

Timo. thanks for the information. I forgot we were talking tracks. The screen of track is similar to the track as used in the MST which we used extensively for the boat operator and with track + sidescan distance for the overlapping runs. this will be nice. for large file downloads I have found www.transferbigfiles.com as a good free way to send large files. thanks for sharing. chuck

Wow Timo!!!

First of all, welcome to the forum!

That is unbelievable stuff and I just want to kick my rear end: I deleted a ton of recordings in the last two days, because I couldn't figure out what recordings I did and where I did them

. Worst of all, I emptied the trash bin and defragged the hard drive last night!!

The side beam feature is really extrem. I didn't even dream that something like this is possible.

Talking about usefull: This is usefull for sure!
I hope I can get HumFinder running on my PC. Having an overview of where I have been already and where I still have to go will give me a way to be more sufficient on time and hard drive space.

Thanks Timo and nice to have you on board!

Timo,

Great wrok and welcome to the forum.

I have added the file to the Download Section here on the forum. You should be able to edit the info in the download section if you like. I did not put a detailed description.

FYI, for everyone, there is a max attachment size in post of 3mb and a max of 15mb in the download section.

Here is the permanent link to the file in the download section:

Timo · « **Reply #13 on:** February 18, 2010, 07:40:08 AM »

Thanks Robert for adding HumFinder to the Download Section. I'll fill in the detailed description later.

Below is a screenshot with "Tip Strips" pasted on the picture. It may give some further information on what kind of functionality the HumFinder has.
Yes, one has to use right decimal separator on numerical values. The separator (dot . or comma ,) is determined on the "Regional and Language Options" of the computer.
Placing cursor on XY-Graph white crosses (SI beam "hit points") on the track, will give a detailed information on that point. The same functionality is provided when showing tracks with Google Earth, but one got to click the round marks.

Timo

Jolly Roger · « **Reply #14 on:** February 18, 2010, 08:37:50 AM »

Hi all,
got HumFinder installed and I'm playing around with it.

I ran into the same problem with the dot (.) and the kommata (,) like Gert, but got that fixed.
Looks like my laptop screen is to small to show the full HumFinder face. Is there a way that I can get the whole screen? My screen setting at the moment is at 1024 x 768 pixel and that's maximum.

Another thing:
As far as I figured out, the position format you use for the map at the moment is DD.DDDD, right?
Can you add the formats Martin uses in HumViewer? That would make it easier to use.

I'm in the learning curve how to use HumFinder, but so far I really like it.
EXCELLENT WORK TIMO!!!

Thanks again / Harry

sonar2000 · « **Reply #15 on:** February 18, 2010, 11:54:11 AM »

OK. explain the fix for the dot or comma error. where do I make this change. is this output data from export to a .csv file? chuck

Awesome.
Timo, I have your program up and running but it is not displaying the same information as you have shown in your screen shots. What am I doing wrong?
This will be very useful for search and rescue. I have always wanted the ability to "see" exactly what part of the bottom was covered, and if anything needed to be rescanned.
Thanks for all the hard work.
Also, as you can see, the window size is not scaled right for my display and I do not have the option to maximize the window.

Timo · « **Reply #17 on:** February 18, 2010, 02:14:18 PM »

Hi Chuck and Harry!

The following formats can be used for position:

------------------------
Enter target latitude.
Formats
ddd.dddddd
ddd mm.mmmm
ddd mm ss.ssss
are allowed.
Use correct decimal separator
------------------------

(as the "Tip Strip" says, which is shown when you position mouse cursor over latitude and longitude controls)

for example, the following coordinates are valid:

123,456789
123 45,6789
123 45 67,89

Countries using decimal point as a decimal separator (United States, Canada, Australia for example)

35.456789 (35.456789 degrees)
35 45.6789 (35 degrees, 45.6789 minutes)
35 45 67.89 (35 degrees, 45 minutes, 67.89 seconds)

In western hemisphere (0 to -180 degrees of longitude) you put minus (-) in front of the longitude.

-100.456789
-100 45.6789
-100 45 67.89

Works the same way as in Google Maps or Google Earth.

In the following link is a list of countries which use decimal point or decimal comma as a decimal separator.

http://en.wikipedia.org/wiki/Decimal_separator

so you can use only degrees, degrees and minutes or degrees, minutes and seconds.

For the decimal separator, you just use the same separator (dot or comma), which you use for example with Excel.
It is set on your computers "Regional and Language Options".

There in not .csv file output, but you can save .kml file with Google Earth, which shows the tracks and data HumFinder generates.

Harry, I am sorry but HumFinder v. 1.0.0.1 requires at least 1280x768 resolution. No problem, I can easily make a version which can be used with 1024 x 768 resolution. I didn't make the application to autoscale to the used resolution at the moment, there seemed to be compatibility problems with certain resolutions. I will try to send a link to new version for 1024 x 768 res. tomorrow.

Below is one of my first recordings, which shows experimenting different Range settings with 798ci. (Notice different extend of scan range on the picture).

Please ask if there is still a problem with position format, or decimal separator. Or any other questions.

Regards,

Timo

Timo · « **Reply #20 on:** February 18, 2010, 03:22:36 PM »

Hello Luther,

Yes, I can see that the SI Range lines are not shown, nor the gray "extend" lines.
I think that you are doing nothing wrong. There seems to be some incompatibility with 1197 recordings and HumFinder.
To correct this problem, I would need to have some recording files for 1197. I have only tested HumFinder with 798ci recordings.

If you could send me (PM) some small 1197 records, or maybe with HumViewer do some subrecording, it would be fine. B002.SON or B003.SON file would do the job.

It would also be nice to have some recording samples of 900-series SI units, as well as recordings done with 455 kHz and 800 kHz.

For window size, please see the earlier posting.

Timo

Thanks Harry,

I received the 455 kHz recording. You are right I will need more mailbox space 10MB is pretty small. Could you please send the 262 kHz recording again - I removed some old stuff from my mailbox - hopefully nothing I am going to miss

I would also need to have recordings from 900 series and 1100 series units to ensure correct operation of HumFinder. The "range lines" seemed to be missing from Luthers recording.

It could be a good idea to use http://www.transferbigfiles.com
for records sending because of the size of my mailbox.
I am sorry if someome got the mail with SI records returned because of the overflow of my mailbox.

Right Timo this recording was made with 262 kHz.

If my memeory serves me right, Lake Constance ("Bodensee") is the second biggest lake in Europe. The one bigger is Lake Geneva. The mountains south of Lake Constance are Swiss Alps.
This is what makes Lake Constance so attractive: In summer you can go swimming, diving, boating or whatever and in Winter you just hop into the car and have the best skiing resorts within an hour's drive distance.
The "Zeller See" is one part of the "Lower Lake" which is one of the two main parts of Lake Constance.

I'll send you some other files in 455 and 262 again.

Hello,

HumFinder release HumFinder v. 1.0.0.1 (1024x768) for screen resolution 1024x768 can be downloaded from

http://www.transferbigfiles.com/Get.aspx?id=2b0aa13f-9b17-4446-bc87-47cc1f80efdc

it has the same functionality as HumFinder v. 1.0.0.1. It can be installed on the top of v. 1.0.0.1 or without it. You don't need to uninstall the v. 1.0.0.1, if you have installed it.

I would like to have some more short SI recordings from 900 and 1100 series Humminbird SI units. Both 455 kHz and 900 kHz recordings would be nice. If someone has recordings done with new models (800 series), recordings would be appreciated too. Just files B002.SON or B003.SON file would do the job.

I was pleased to see that my mailbox size was changed already to 100MB so there should be room now.

Hello,

Chuck, I got the files, or actually one .son .idx and .dat file. (Probably those were yours)
Those SI files helped me to solve the problem with minus (-) longitudes and it had the same effect on minus latitudes as well (southern hemisphere). The Si record "Range lines" (swath?) wasn't shown on those areas.

Below is pictures of SI track from file that helped me to solve the problem. Many thanks to the sender!
Haven't got yet any records done with 800 kHz, please let me know if HumFinder can handle those as well.

Tip of the Day:

- You can doubleclick the XY-graph and doubleclick or drag map on Google Earth to search for SI tracks on that position.

- The search folder can be selected from (Folder icon)folder, above folder path control. By selecting C:\ all the Humminbird SI tracks are searched on all subfolders on drive C. That might take time though, so it's better to use folder that contains all or part of the recordings as subfolders, depending on selected search.

Timo

Timo · « **Reply #36 on:** February 21, 2010, 08:42:38 AM »

Hi,

Yes Harry, I will include a "Cancel Search" button in later release of HumFinder. In the meantime, if someone wants to search the whole disc for HB SI records, it's good idea to have that coffee break.

The laptop I am working with now contains about 20000 folders and hundreds of thousands of files - so it's takes time to search the whole disc. In a case that you know that the recording on some interesting area is somewhere there among folders - but where? - it might be worth some coffee.
In my case, if I select folder which contains all my last years recordings as subfolders ~20 GB, it takes about 10s to have the tracks of selected area on the screen. The time depends somewhat on how many records are on that selected area.

Chuck, I would like to have some short recordings done with 800 kHz on 900-series or 1100-series units. If you have any, I would appreciate your help.
Please, send also the recording (or part of it), which still doesn't show the "swath". Did you install HumFinder v. 1.0.1.1 or HumFinder v. 1.0.1.2 (1024x768). (Download links in yesterdays post). That should have corrected the bug which affected feature in negative latitudes and longitudes.

Tip of the Day:

If there is any snow and the temperature is "decent" (-15 degrees celsius, 5 Fahrenheit) it's time to put your skies on and do some cross country skiing - I aim do do that next.

Timo

Timo,

The new versions of Humfinder do display the swath on recordings done on my 1100 at 800khz. In fact it showed 24 tracks that were parts of a search pattern. Is it possible to make whatever was causing the swaths to display a toggle feature? While the swath display is very helpful close in or when there are few tracks, I can see where showing just the tracks could be just as good in circumstances where you have a large number of tracks in the area of interest and you just what to know the location of one track to another.

Is there a reason that the search area is limited to a 3000' radius?

I can send you 800khz files taken with a number of different HB firmwares if that is something you still need.

Thanks for letting the rest of us benefit from your efforts!

Mike

Timo · « **Reply #38 on:** February 22, 2010, 03:54:16 AM »

Thanks Mike for the information!

Yes, sure I can make the swath display selectable by the user. I'll open up a new topic, in which the users may post development and nice-to-have feature ideas for HumFinder further development. I will add this idea to the list.

One can also select "Show only hits" to decrease cluttering, if there is lot's of recordings on the selected area. Search radius can also be decreased.
While developing HumFinder I thought of using two modes:
Mode for finding records and showing associated information pertaining to some interesting point (target point) along with record name and recording time of "Hit points" or target illumination points to easily find that particular object with viewer application. Another mode could show larger area to distinguish between scanned and unscanned areas.

As well as the HumFinder development ideas topic, I'll add HumFinder "Bug Reports" topic, which can be used as the name tells. I'll try to fix the bugs as soon as is possible, while bundling up new feature ideas and making new release as appropriate.

Mike, the reason for limiting the search are to 3000' (1000m) at the moment is that I haven't tested very much how large the search area could be before errors in coordinate system comes significant. It have a feeling that it can be much larger than at the moment with the methods I am using with the HumFinder. I'll have to do some testing and accordingly increase the max. search radius.

I would appreciate if you could sent those 800 kHz files, they would be helpful. Recordings done with 4.700 and 4.750 firmware would nice.
My mailbox has a lot of space now!

Timo

Lat and Lon are -96.592 and 32.296. When I hit Search SI Records, it seems to quickly load the recording, but then nothing else happens. I know this is going to be embarrassing, but how do I get it to run? I am using standard 32 bit Windows XP.

Bob,
make sure to choose the right format for the LON/LAT boxes.
Timo posted the right formats somewhere in the HumFinder post.
Also make sure you choose the right prefixes.
Extend your search radius to 3000 feet. If the patterns show up, just doubleclick on them and the screen will center on them.

Hope this helps!
Harry

EDIT:

Here's Timo's<advice concerning the format:

"DDD,DDDDDD Degrees
DDD MM,MMMM Degrees and Minutes
DDD MM SS,SSSS Degrees, Minutes and Seconds

Notice correct decimal separator: dot (.) in United States, Canada, Australia etc. Comma(,) in Europe... According to your PC settings.
I have tested for correct operation in minus latitudes (0 - -180) - seems to work OK. UK coordinates should not be a problem."

Thanks, Harry. The 3000 feet got me within range to make the tracks appear. I had missed that completely - thanks again.

Timo,

Looks like you aren't to far from mosaicing. Why not plot the side scan data with the tracks? I have been slowly working on some code to mosaic. I'm to the point where I'm generating images from the side scan data and have it scalable (if you tell me the pixel size in spacial distance, say ft or meters ) i can plot the data correctly. let me know if you are interested. He is a image of a recording.

Fantastic work

Thanks nsmith997C,

I have thought about mosaicing capabilities with HumFinder, but those are more or less just some ideas which have popped into mind. I think that there is some restriction coming from GPS position inaccuracy (which can be in the worst case at least 6 meters (20 feet) with AS-GR50 and AS-GRHA, yet more with older models. That will have effect on what heading information you got from SI unit. The heading information is quite crucial on this kind of stuff, so that mosaicing would work acceptably in other than "ideal" conditions too. (I had ecpecially in mind the case when there is more than one SI track to show)

Sure I am interested in your development with mosaicing. The picture you sent is great!
Please, send me PM for more information exchange if you like.

Thanks, great work!

Timo

Need to change the first ftp to http then it works.

) We discussed this also in the chat but were afraid to ask (yet).
Get rid of the watercollumns also and you have the perfect thing.
