Making Tracks on Vancouver Island – Completed Contest

A new contest for vigps users.

This contest has been modeled on GPS Drawing (http://www.gpsdrawing.com/gallery.htm). You walk, bike, drive with gps in hand, creating an interesting looking track file, and your fellow vigps.com users will decide who has made the Best Track on Vancouver Island.

Deadline: Midnight December 1, 2004.

How it works:

The track must be made on Vancouver Island, must be made on land, and must be at least 1 k in length.

Each entrant may submit a maximum of two tracks (entries).

Entries will be emailed to contest@vigps.com as an OZIexplorer format track file.

Screen shots will be placed online. The entrants name will not be published until after the winner has been announced.

Prizes are contributed by contest entrants – drop boxes are available in the Victoria, Nanaimo and Comox areas. You will submit one prize for each drawing entered.

After the contest deadline (December 1, 2004), everyone signed up on the vigps forums will get one vote. Voting will not be available until after all entries have been received.

All entries must be received by December 1, 2004 at midnight.

What do do:

  1. Create a track.
  2. Email your OZI format track file to contest@vigps.com, and ask a the prize drop location.
  3. Email contest@vigps.com after you have placed a prize in a drop box so it may be quickly retrieved.

Notes and tips:

When you are about to begin your track, delete all tracks from your gps. Make your pretty drawing, then save your track in your gps, or turn your gps off.

Hurry home (drive carefully!), open OZIexplorer (www.oziexplorer.com) and “Get Track from GPS”. Do not alter your track. Gaze upon the wondrous beauty of your masterpiece, save the track file and email it to contest@vigps.com

After submission, your track file may be edited to remove stray points outside the drawing area – ie, those used to get you to and from your drawing location.

Until we see how many entries and prizes are available, we will assume that the winner takes all, or, in the event of a tie, prizes will be randomly distributed equally among the winners. If a significant number of entries/prizes are available, there may be prizes available to the top three.

A Primer on Nautical Units of Measure

Written by CandC

As I have found out, much to my surprise, there are many different measures of the same thing in use in the Nautical world. These measure can be confusing, but also a great way to make a geocache more interesting. I have found two sources of information that are particularly helpful, though some times contradictory: The Admiralty Manual of Navigation, by the U.K.’s Royal Navy and The American Practical Navigator, by the U.S. National Imagery and Mapping Agency and known sometimes as “Bowditch”.

Here’s how the units breakdown:

Unit Admiralty (U.K.) Bowditch (U.S) Note:
International nautical mile (nm) 1852 m 1852 m US Dept of defence uses 6076.11549 ft with a yard to metre conversion of 1x=0.9144m exactly. (From Bowditch)
Geographical Mile 1855.4 m 6087.08 ft (1855.52 m) The official definition of this unit is according to both sources “1 minute of arc along the equator.” The admiralty figure given here uses the 1924 spheroid.
US Survey Mile N/A 5280 ft(1609.5m) Used on rivers and inland waterways.
Sea Mile 1842.9 m at 0d 1852.3 m at 45d Same as nautical mile Defined by the admiralty as the length of 1 minute of arc of latitude. Figures are given for the 1924 spheroid.
Statute Mile 1760 x, 5280 ft N/A Note this is the same as a US Survey mile.
Cable Depends on Latitude (aprox. 200x) 185.2 m Defined by both the Admiralty and Bowditch as one tenth of a sea mile. Note that sea miles differ according to the source. The Admiralty points out that a cable is most often approximated as 200 yards. [Apparently, a cable once considered to be 120 fathoms]
Fathom Not given 6 ft (1.82898m)
Shackle [12.5 fathoms (22.862m)] [15 fathoms 27.435m] Neither of these measures is given by either source, however these measures are still used by mariners, to the best of my admittedly limited knowledge.

Note:

  • Figures in (round brackets) are my conversion and have been converted using 1ft=0.30483m.
  • Text in square brackets is from The Sailor’s Illustrated Dictionary by Thompson Lenfestay, and is attributed to a particular country.
