請各高手教路:
因工作關系買了Garmin eTrex GPS機,但機內的香港地圖只是模擬式,我同時買了Garmin 的Blue Chart 海洋圖CD ($1800)。
千辛萬苦安在PC的MapSouurce軟件中,但老闆要在GPS機安上Blue Chart 海洋圖,請各高手教教點樣安裝在機內。
另:在網上看到很多香港陸路圖,可以下載的(IMG檔),要怎樣安?
謝謝幫忙!

當多日外出使用,把每日的航跡儲存後,最後把儲存好的航跡上傳到電腦上,航跡上的時間和速度的資料原全失去。且航跡和原本的有出入。
想問問有何方法可張資料全部保留,航跡不變。試過用GPilots (Palm),但依然無法全部資料保留,又無可能帶notebook同行,各用家有何方法解決此問題。謝謝!

Only the Active Log keeps the altitude and time information. (etrex and it's relevant model can only keep ONE active log and 10-20 backup log, depend on the model)

Please notice that all the tracks you SAVED to the backup log will be trimed and eliminated to fit the memory limitation. Therefore, I sugget not to use the backup log for storing important data.

Since the Active log is limited in size, the log will be overwritten if you don't backup it everynight or it can't be recovered once you have deleted it.

I didn't use GPilots before but it should be fine for storing the ACTIVE LOG every night when you arrive the camp.

For me, I use OziExplorer CE for backup purpose since it fully supports Etrex GPS.

Hope it can help

Thanks Kin,記得我嗎?(地圖)
可惜我無PPC,遲下看看弄部二手PPC試試看,到時找你幫忙下。

   By Kin on Saturday, December 28, 2002 - 12:02 pm:  Edit

That's OK!

But I guess your Palm can also do that...

   By paliny on Monday, December 30, 2002 - 9:02 pm:  Edit

Hi Kin
I want to know if I save the track in OziExplorer CE. That file can be used directly in OziExplorer (PC) ?

   By Kin on Tuesday, December 31, 2002 - 10:06 am:  Edit

Sure, they are using the same format.

   By Kin on Thursday, January 16, 2003 - 10:23 am:  Edit

OziExplorer Track log file format (.plt file)

Line 1 : File type and version information
Line 2 : Geodetic Datum used for the Lat/Lon positions for each trackpoint
Line 3 : "Altitude is in feet" - just a reminder that the altitude is always stored in feet
Line 4 : Reserved for future use
Line 5 : multiple fields as below
Field 1 : always zero (0)
Field 2 : width of track plot line on screen - 1 or 2 are usually the best
Field 3 : track color (RGB)
Field 4 : track description (no commas allowed)
Field 5 : track skip value - reduces number of track points plotted, usually set to 1
Field 6 : track type - 0 = normal , 10 = closed polygon , 20 = Alarm Zone
Field 7 : track fill style - 0 =bsSolid; 1 =bsClear; 2 =bsBdiagonal; 3 =bsFdiagonal; 4 =bsCross; 5 =bsDiagCross; 6 =bsHorizontal; 7 =bsVertical;
Field 8 : track fill color (RGB)
Line 6 : Number of track points in the track, will be recalculated when reading file
Trackpoint data
· One line per trackpoint
· each field separated by a comma
· non essiential fields need not be entered but comma separators must still be used (example ,,)
defaults will be used for empty fields
Field 1 : Latitude - decimal degrees.
Field 2 : Longitude - decimal degrees.
Field 3 : Code - 0 if normal, 1 if break in track line
Field 4 : Altitude in feet (-777 if not valid)
Field 5 : Date - see Date Format below, if blank a preset date will be used
Field 6 : Date as a string
Field 7 : Time as a string
Note that OziExplorer reads the Date/Time from field 5, the date and time in fields 6 & 7 are ignored.

Example
-27.350436, 153.055540,1,-777,36169.6307194, 09-Jan-99, 3:08:14
-27.348610, 153.055867,0,-777,36169.6307194, 09-Jan-99, 3:08:14

Hi Kin,
I'm new to GPS, my model is Garmin eTrek Summit.
Please help : is it correct that I only have to connect my GPS (with the specific cable bought) with PC, without any driver, they then can communicate through OziExplorer.
Thanks, Ming.

   By Kin on Friday, January 24, 2003 - 10:15 am:  Edit

Ah Kow,

I own a eTrex Summit too!
Basically, OziExplorer does not require any Drivr to communicate with Summit.
You can simply get/send your data from/to your summit using the native function of OziExplorer.

Hi Kin,
Thanks for your helpful information.

   By Steve on Tuesday, February 04, 2003 - 7:49 pm:  Edit

Hi Kin,

Can I download the saved route from the etrex to OziExplorer Trial version?
Or I have to register it first?
Many thanks =)

   By Kin on Wednesday, February 05, 2003 - 10:11 am:  Edit

You don't need the release version to download the track. You can do any thing in trial version except that you can calibrate your map using more than 2 points.

So make sure you have your cable well connected and prepare a scanned map. (Since you can only calibrate 2 points in trial version, so make sure the map grid is rotated to align the map margin)

   By Kin on Wednesday, February 05, 2003 - 2:42 pm:  Edit

Sure, you only need a well connected etrex cable and a well prepared scanned map.

However, the trial version only enable 2 points calibration. So please notice that you must sightly rotate your map and align the grid line to the map margin.

Thanks very much

Garmin has released a new firmware version 3.10 for Vista and Legend.
The new firmware largely improve the GPS storage capacity to 10000 points tracklog.

Please visit Garmin website for more info.

   By AY on Thursday, February 13, 2003 - 5:10 pm:  Edit

Thank you, Kin.

How do you know which firmware version we are using now? I can't find it from the receiver.

   By Kin on Friday, February 14, 2003 - 10:39 am:  Edit

As I remember, Go to the setup page of your eTrex and it has a button to check your version information.

   By AY on Monday, February 17, 2003 - 9:54 pm:  Edit

Kin,

I have updated the firmware from version 2.5 to 3.1, thanks to your advice.

But do you know how I should configure the OziExplorer to take advantage of the improved capabilities of the new firmware.

Thanks again.

   By Kin on Monday, February 17, 2003 - 11:06 pm:  Edit

Did you try to use up all 10000 pt storage capacity in your Vista/Legend??

I don't own a vista so I didn't try. However, I have opened a 10000 line .plt file in OziExplorer for testing purpose. The track can still be loaded but the respond is much slower than it dealing with a 2000 pt line.

I suggest you to save the 10000 pt track once and re-open it by a text editor.
Then split the track into 2 or more seperate track. You can easily re-construct a .plt file by the specification in the thread above (By Copy and Paste, please reference the thread posted on 16/1).

Hi,
Where can I buy the PC cable for the eTrex series (better place with cheaper price) and how much is it ?

I saw from Garmin's page, the official price is very expensive, for the cable which is rather simple..

Any idea ??

Please call the official HK vendor. They now got an OEM cable(Not produced by Garmin), which is cheaper in price.

中原地圖那個圖庫是一張過的﹐offset 是由圖的左下角開始計算。不能說不可以﹐但似乎要用復雜的測量公式計算﹐而且我也不知道公式堛 parameter.
