NoWhere - yet another geocaching appilcation for mobile phones
DDD° MM.MMM', DDD° MM.MMM' N 48° 12.345', E 12° 34.567'whereas TomTom only shows coordinates in this style:
DDD.DDDDD°, DDD.DDDDD° N 48.20575°, E 12.57612now for a normal geocache this is no problem - you calculate your destination coordinates at home and enter them in the format the device likes.
But for a multicache it becomes nasty, you only discover coordinates for the next hint on the way, and have to calculate them en route. Sitting with a calculator or the calculator SW in your mobile phone takes much of the fun of geocaching.
For some month I use a Nokia E71 - it was recommended to me, and I like it - the type of bugs and crashes is different, but its a revelation alone not to see random windows error message popups. Mobile SW still has a long way to go.
But the Nokia E71 is not any better, GPS wise. The shipped Nokia GPS application only shows coordinates in the same format as TomTom:
DDD.DDDDD°, DDD.DDDDD° N 48.20575°, E 12.57612°So I started looking for a simple geocaching SW that met my requirements:
- runs on one of my 2 devices - royalityfree - coordinates displayed in the geocaching style DDD° MM.MMM', DDD° MM.MMM' - works offline (I don't have a flatrate nor am I expecting every cache to have 2G/3G coverage, also I am unwilling to pay) - opensource would be nice but is no mustI looked at like 10 different "solutions" which all failed for me. So I did something - and hopefully unique - I wrote a JAVA(tm) program:
It's very minimalistic, and has all features you need for a successfull sunday multi-cache.
you can download it here:
- NoWhere.jar - NoWhere.jad - sourcecode: git clone firstname.lastname@example.org:/git/NoWhere.git password: git-pub
For building I used the Sun Java Wireless Toolkit for CLDC
Update: obviously I couldn't have gone through all the pain of java without the help of a friend - thanks Simon!
