Does anyone keep thier hiking tracklog ? It would be nice if we have a database to store all the possible hiking tracklog and let others to make full use of it.

Hiking tracklog is not just waypoints, it should be the tracklog from the start to the end. The resolution should not be larger than 25m.

How we start?

What I am doing is that I have my GPS switched on from the beginning of the hiking to the end. Then the track log would be downloaded to my computer and superimpose onto my scanned HM20C map

So how can we share? You have a site for download those log?

   By madmac on Monday, October 15, 2001 - 5:15 am:  Edit

I current using Garmin Map Source as management of track and waypoints. And should do the same record as you do when hiking.
So how can we share out track log? What format is yours?

Example for my OziExplorer Track, of cox I can export to other format.

Please give me a your no. by email to mactrash@hkmedia.com and I we can talk detail in phone, better give the the best time to call you too.

I have just brought a eTrex GPS. I like your idea to share the Tracklog files.

Is there any common place to upload this files?

   By kchan on Friday, November 23, 2001 - 4:26 pm:  Edit

Hi KW,

I am working with hiking.com.hk webmaster on this matter, any suggestion?? We have to define a file format first, currently I am using OziExplorer 3.9.

There is some information on scanned map and software in GPS section.

   By madmac on Friday, November 23, 2001 - 7:30 pm:  Edit

I think I can provide mapsource file as well. so we better use 2-3 format for one log, since other brand may be just input text file well

   By kchan on Saturday, November 24, 2001 - 2:03 pm:  Edit

text file format such as my second example and
mapsource format should do the trick.

   By Yip on Monday, November 26, 2001 - 11:10 am:  Edit

Is the evaluation version of OZI explorer got time limit? or some function has been locked?

I am interested to share my log, when will the sharing section start? and also, Is it possible to share the map file to me?

Features for registered Users

No Nag screen

User selectable datums - You can specify separate datums for each and every map you create, specify the Datum you have set for your GPS and specify the Datum you use for the Data files. The software will automatically convert the position coordinates (Lat/Long) from the datum system specified for the GPS or Data files to match the datum system specified for the map as data is downloaded from the GPS or read in from the data files. The opposite will occur as the data is uploaded to the GPS or saved to Data files.

User Selectable Map Projection - The following Map projections are suppported, Mercator, Transverse Mercator, Lambert Conformal Conic, Sinsusoidal, Polyconic (American), Albers Equal Area and others. As well as any map projection required to support the Grid systems mentioned below.

UTM, BNG, Irish Grid, New Zealand Grid, Swedish Grid, Swiss Grid, France Grids and User Grid coordinates systems - Where a position is required you have the option to enter these in Degrees & Mins or one of the Grid systems listed above. You also get the ability to print the Waypoint and Event lists with the selected grid.

Import USGS DRG maps on CDROM - This feature allows you to import these map images and automatically create OziExplorer maps. The calibration of the map in done automatically.

Import BSB and NOS/GEO charts on CDROM - This feature allows you to import these chart images and automatically create OziExplorer maps. The calibration of the map in done automatically.

Import Maptech PCX and RML charts on CDROM - This feature allows you to import these chart images and automatically create OziExplorer maps. The calibration of the map in done automatically.

Merge Waypoints and Events - For Lowrance/Eagle and Garmin Receivers only at this stage. When downloading Waypoints this provides the ability to merge the Waypoint with those already on the map.

MapView - This provides you with a small view of the map which shows a red rectangle which is the area you can see on the large map. You can the drag this rectangle over the small map and when released the view of the large map will change to suite. Waypoints, events and the plot trail also plot on the small view of the map.

Send Single Waypoints and Routes Direct to GPS - For Lowrance/Eagle Receivers only at this stage (ability to do this for Garmin Receivers to be done soon). A single waypoint can be sent directly to the GPS by point and click (right click on the waypoint and select option from menu). A single Route can be sent or retrieved from the GPS by pressing the buttons on the Route window.

Multi Point Calibration System - This allows up to 9 points to be used to calibrate the map. This allows for rotation and skewing of the scanned map. By using more points an "over determined" solution can be found to provide even more accuracy.

Ability to alter Moving Map settings.

Hi Webmaster,

I am still studying how to use the GPS unit. I am not experienced enough to give you any idea in this moment.

I would like to hear what the other experience user say.

By the way, is there any free software for my old Palm Pilot? I think Palm is more convenient to carry.


Thanks a lot

   By kchan (Kchan) on Sunday, December 02, 2001 - 5:30 pm:  Edit

Please check out the following link, I don't know
any freeware, not checked.

   By Yip on Monday, December 03, 2001 - 9:47 am:  Edit

I have downloaded OZI explorer any try running it in my computer.

Do anyone got some scanned map in any graphic format (or any scanned map which imported into OZI explorer and cliabrated already), so I can test my GPS with OZI explorer?
I don't have any scanner so I cannot do it myself.

Really thanks for anyone who can help on this.

   By kchan (Kchan) on Monday, December 03, 2001 - 9:51 am:  Edit

where would you like ??

   By Yip on Monday, December 03, 2001 - 10:06 am:  Edit

It doesn't matter about the place of the Map. I can visit the Area of the map once, for testing the GPS with the OZI explorer.

   By kchan (Kchan) on Monday, December 03, 2001 - 1:48 pm:  Edit

can't post on here, takes too much disk space.
send me an email, I would email a copy of scanned map and the map file but it can only be used with registered version. The scanned map cal. is done using 8+ points which can't be opened using a shareware version.

   By Jacky on Friday, December 07, 2001 - 1:36 pm:  Edit

Any one can give a suggestion if i want a GPS unit. The price is about HK2000.
Thanks.

   By kchan (Kchan) on Friday, December 07, 2001 - 1:41 pm:  Edit

Try eTrex check out shop list here,

GPS Section

give them a call, check the price, may be their price tag is lower, but not sure.

   By Steve on Monday, January 07, 2002 - 9:42 pm:  Edit

I just bought a etrex legend and wondering whether I should use Mapsource or OZI Explorer to manage the tracks and way points. Can anyone give me some ideas?
Thank you very much.

   By kchan on Monday, January 07, 2002 - 10:15 pm:  Edit

Maps from MS does not have much detail about Hong Kong, and it can not use scanned map, on the other hand, OZIExplorer is for scanned map.

hope this help

   By steve on Monday, January 07, 2002 - 10:28 pm:  Edit

Thank you. By the way, is it hard to calibrate the scanned map and does the software have any instructions about that?

   By kchan on Tuesday, January 08, 2002 - 8:58 am:  Edit

it is very easy, just maek a number of points and key in the UTM of those points.

It's a good news to have such a tracklog sharing group, but how can I upload the files to the server? I have some tracklog prepared and wanted to upload.

I have tried to follow the step at

Could you tell me how to do that?

Kin,

Please look at this page for help instead
http://www.hiking.com.hk/discus/messages/59/2257.html
Example
http://www.hiking.com.hk/discus/messages/59/4286.html
as the procedure for uploading tracklog is little bit different.

You should use
\attach{ptA_ptB.zip}
instead

Webmaster,

After I clicked "預覽/發表文章"
I can only see a "Clip" logo and 3 more buttons,

I can't see the button that let me to choose the file, how can I make it appear?

   By Wembaster on Wednesday, January 23, 2002 - 2:35 pm:  Edit

This is normal, continue to click - "發表文章",
Then it will prompt you to upload

   By Kin on Wednesday, January 23, 2002 - 2:37 pm:  Edit

Done!
Thanks, webmaster!

   By Kin on Thursday, February 07, 2002 - 10:30 am:  Edit

If someone wanted to use the tracklog data shared on the board, please make sure the maximun track point capacity of their GPS unit is sufficient to store all the track point.

If using some GPS unit which has lower storage capacity, let's use OziExplorer 3.90 or above, It has a Track Filter function to help shorten the no. of track point.

Most of the GPS model selling in HK does not support User Definable Map.
However, some Lowrance's GPS let you to import your own map my using some manufacturer software. but this brand is not popular in HK.

If you are using garmin GPS, the HK street map is now available in some units.

If you only need the digital map for private use, I suggest you to scan your own map. It is because the map selling in Government is very expensive
Normally, I scan the map using scanner, then put the map into OziExplorer and all done!

Thanks for your advice.
I've recently bought a Garmin Vista with the HK street map. I'm still learning how to use it.
However, the street map seems not quite suitable for hiking in NT (since I want to plan some routes not shown in that map).
I think your idea of scanning individual map and OziExplorer sounds good to me. I'll look up the OziExplorer.
Do I have to buy the MapSource in order to use OziExplorer?

   By kchan on Wednesday, March 13, 2002 - 12:05 pm:  Edit

MapSource is from Garmin, OziExplorer is another software from Oz. Check out the link provided on section 人造衛星定航儀 GPS

   By Kin on Wednesday, March 13, 2002 - 3:33 pm:  Edit

Luk, how much did you buy the Vista with HK map? Is it chinese/english version?

And finally, did you buy from the dealer?

   By Luk on Wednesday, March 13, 2002 - 10:21 pm:  Edit

-Vista: $2980 (at the dealer, $3480 at Ap Liu St)
-Downloading HK Street Map (English): $500 (only available from the dealer).

I am trying the demo version of OziExplorer and the "HK Electronic Map 2002" by WanLi. Using them together with the HK Street Map seems easy to have route plotted all over HK. I think another US$75 will have to be spent.
I'm learning how to use them, but still a long way to go...

BTW, Geocaching sounds interesting, have you tried playing it?

   By Kit on Thursday, March 14, 2002 - 3:40 pm:  Edit

Anyone bought the HK Street Map, how was it ? Very details and useful ? I have a Vista as well.
I have notice the original HK map come with the Visita is not accurate, especially area that has been land filled (Like Kowloon Bay), it will said it is sea area, but actually, it is land now. Did the HK Street Map update this as well ?

   By Kin on Thursday, March 14, 2002 - 4:37 pm:  Edit

I would like to ask what is
HK Electronic Map 2002" by WanLi??
Is it just a electronic Map inside a CD-Rom? It seems that this map does not has any grid line in it, so is it hard to calibrate the map with OziExplorer??

Only few Geocaching boxes are available in HK. I visited some of them but it is unavailable now!

I think the people who play Geocaching should follow the rules! that is, re-installing a new treasure after they take out the old stuff!

   By Luk on Friday, March 15, 2002 - 3:26 am:  Edit

The HK street Map is quite good, 2002 version.
I can see the reclaimed land of Kowloon West, Piers of Central, airport railway, new airport... etc. Roads not very detailed (main roads only, no small streets).
I find it useful when I use the street map's co-ordinates in the GPS's "Pan Map" function to calibrate the maps in "2002香港全境多功能街道圖(萬里)" for OziExplorer. And I found the error is acceptable in urban areas (may be because roads intersection is easy to compare between the two).
I'll try and test some calibration in the rural area later.
The WanLi(萬里) maps is the one in CD Rom. Its cheap (in MK computer centre), have 130+ scanned maps of HK in JPEG format. Good for me who don't have a scanner. However, the details are far beyond HM20C series government maps. Anyway a acceptable choice for beginner like me.
Today, I just finished the tutorial in the Oziexplorer. Waypoint 1 only, still a long way to go...

   By Kin on Friday, March 15, 2002 - 10:33 am:  Edit

So please notice that the width of the road on the map may not showing the exact width from real world. so you must be careful to find the points to calibrate. (eg. not calibrate on the boder of the road. Maybe using the center of road junction can return higher accuracy)

If you are using Garmin GPS, some functions in OziExplorer is useless for you (eg. event)
So, you can focus on studying more on waypoints, tracklog and route. Or even Realtime netvigation...

Hope this may help.

   By Luk on Friday, March 15, 2002 - 7:26 pm:  Edit

Kin,
What do you usually use to calibrate the maps, deg-min or UTM system?
I often lose signals in urban area where there are buildings on both sides of the road (sometimes even one side). I'm using Garmin Vista, is that normal?

   By Luk on Sunday, March 17, 2002 - 11:29 pm:  Edit

Which Map Datum should I use:
HK1963 or WGS 84
for HM20C maps and the HKSAR Sai Kung Map during calibration?

   By kchan on Monday, March 18, 2002 - 8:43 am:  Edit

UTM, WGS 84.
HK63 and HK80 is outdated although HK80 and WGS84 are shown on HM20C, it is wise to use WGS84 UTM.

   By Kin on Monday, March 18, 2002 - 9:53 am:  Edit

I normally use WGS 84 for all country map as well. except I got some using low-scaled map using Degree,min,sec.

It is normal for the most GPS unit for getting such symptom. It is becaus the building beside the road blocks the signal. (Therefore, it is not suitable to use GPS in HK urban.)

By the way, because the etrex is using a internal antenna, so it may also affect the receiver sensitivity

Using your Vista in the middle of the road (eg. driving on the fast line), does return better result than using it at the roadside. My experience is that, even you are moving in the same street, the strength of the signals are variant depend on the Time you walk. That's because the satellites are in different sky position at different time.

The best way of using your GPS is to keep yourself moving. The vista does resume the signal when it has a clearer view of sky

   By kchan on Monday, March 18, 2002 - 3:02 pm:  Edit

If you would like a better result, try DGPS, but you need a DGPS antenna with external power. I don't know about WAAS in Hong Kong. with SA turned off and at least 4 birds locked, 10m accuracy should not be a problem. but with buildings, multi-path signals and less than 4 birds i.e. 2D lock will degrade the accuracy.

   By Steve on Monday, March 18, 2002 - 4:32 pm:  Edit

The detail of coastline in the new HK street map has been improved. I have compared the street map with HM20c also, found that the new street map has marked out the boundaries of country park quite well also.

   By Kit on Monday, March 18, 2002 - 4:45 pm:  Edit

Agree with Kin, when I am riding a minibus and turn on the etrex Vista, it record quite well except when there is bridge blocking the sky and going under the tunnel. One bad thing I am not happy with the GPS is it altimeter, it use barometeric data and it is quite different in the morning to the night time. So, the altimeter is not accurate at all.

   By Kin on Monday, March 18, 2002 - 5:10 pm:  Edit

Kit, don't worry about it, Your GPS unit does auto-calibration itself!
Actually, It take the MEAN of GPS height from the record of previous period (I don't know how long it sample, maybe half hour) It will tune the altimeter reading. Remember, it's not a instant process. It always take half hour to make the reading become accuracy.

If you want the GPS unit calbrate the height faster, try delete the Current Tracklog (if you don't need it). Calbration goes faster because the unit is taking a mean with fewer samples.

The above operation is only known in Garmin GPS only.

   By kchan on Monday, March 18, 2002 - 7:23 pm:  Edit

In serious use, barometric altimeter needs to be calibrated before use. All you need is a known alt. and calibration.

(non-barometric found in GPS12/GPS3+)3D GPS altimeter is useless, with birds so high up in the space, the time difference between these birds isn't good enough to yield meaningful results.

   By Kin on Tuesday, March 19, 2002 - 10:57 am:  Edit

Some research stated that, the ALT return 1.5 times more error than horizontal error.

The benefit of altimeter is that, you won't see the height of your unit jumping around, even you are just seatting on the ground.

As the user manual suggested, always calibrate the altimeter if you know the exact height.(eg. Calibrate every 2 hours) If you really don't know, then trust the auto-calibration, especially when you are in wild open area, It gives you what you need.

   By Luk on Wednesday, March 20, 2002 - 3:46 am:  Edit

Do you buy and scan you own maps?
Anybody want to share maps?
How about we form a group to buy and scan maps and then share among us, so that if we have four people, for $200 each paid, we can buy the whole series (16 maps) of HM20C, or any other series you suggest.

Right, the site is:
http://www.info.gov.hk/landsd/mapping/mp/chtml/index.htm
The detail is too low, no contour. But it's free!

I have just buy Garmin Legend 中文版.
Can anyone tell me how can I transmitt the date to computer.

I have got the cable.
But where can I download the software?
Which software?
Thx

   By Kin on Saturday, March 30, 2002 - 10:02 pm:  Edit

去download OziExplorer 啦

I've got a problem:
After I had calibrated the "Tai Po Kau" map (Countryside series) using the UTM coordinates, the Lat-Long readings shown by OziExplorer did not coincide with that on the map.
I also did the same type of calibration on the "Central NT" map (Countryside series) and it gave correct readings.
When I used the hill 408 as a reference point on the above two maps, they gave the same coordinates on both of them.
Is there something wrong in the "Tai Po Kau" map?
Which is better to use in calibrating maps in OziExplorer, UTM or Long-Lat?
Luk

   By Kin on Wednesday, April 03, 2002 - 2:12 pm:  Edit

I always use WGS84 to calibrate the map. It is very convenience as I only need to use the grid line printed on the map.
In the Tai Po Kau Map, I use the coordination:
50Q
0209000
2483000
to calibrate with the Upper-left grid line junction.
Afterward, please choose 3 more corner as a reference point. Then the map can be cabibrated.

   By Luk on Friday, April 05, 2002 - 8:21 pm:  Edit

Kin,
I've found the answer to my problem:
The Lat. printed 114.10E is wrong, it should be 114.11E in that map (Tai Po Kau), I've double checked it with the NT Center.
I now use the UTM system to calibrate all the maps you gave me, really simple and accurate.
I also combined the two Lantau maps into one.
But I can't combine the Sai Kung maps due to the impotency of my PC (file to large).
Luk

   By Kin on Sunday, April 07, 2002 - 1:07 am:  Edit

Usually, I cut a portion of the map for using in OziExplorer. It is because my computer is not a powerful one.
I do the stitchwork on demand only when the portion of map is seperated into two.

最近把自己的tracklog 放在 OziExplorer 內,配上一張郊區地圖,製作了一系列的行山路線圖.

遲些有空,或會把所有路線製成圖像,放在自己的網頁,好讓沒有GPS和OziExplorer 的行友也能看到路線.
