Does anyone know of a site for downloading a FREE tide predicter for an Ipaq handheld. I have used the wx tide on my computer which is an excellent program, unfortunately it does not work on a pocket PC. /forums/images/graemlins/confused.gif
The number of views on this subject has exceeded a lot that have been posted . From that I draw the conclusion that this is an important/interesting subject. Are there no boffins out there that can produce a predictor for the Ipaq pocket PC
cTide is free (http://airtaxi.net/ctide/index.htm#files) and is based on WxTide32 and runs on Ipaq and Palm. However, while it covers the rest of the world well, for Europe it only covers the Netherlands as far as I am aware.
Given that it is based on WxTide it maybe that the cTide database is similar and data from that used to add to the cTide one. I have not explored that (cTide has excellent coverage in our own waters) but seem to recall some mention of doing that somewhere - full source code and the database file (text) is available with cTide.
Seems to do accurate predictions, but my experience of it is mainly as a backup to the tide calc's on the PC.
It looks like the xtide files may not have harmonics for Portugal (I have not downloaded them off the xtide site to open them and check though - just gone by the single text list they give).
But I have had a quick look at the harmonics file for WxTide32 (which is a Windows port of xtide and a google will take you straight to it) and it appears to have harmonics for at least some Portuguese locations.
How easy it is to get these into the cTide database I have not checked, but the cTide databases are txt files also so it maybe possible and even straightforward. Obviously alot easier if someone can suggest another iPAQ program in which case I will be interested in it too.
I found the following but it is way beyond my capabilities around a computer!
Getting New Data
As was mentioned in How Does This Work?, to update this program with newer data files you need to get your hands dirty. How to do this is not a drag and drop operation. If you are prepared to get your hands dirty read on. The original XTide program of David Flater, lots of excellent information on the prediction methods and links to new data files can be found at www.flaterco.com/xtide/.
The harmonics files are maintained by Bob Kenney and can be found at his website:
If you do download new data files, you will need to find the source files of cTide which are located in the file cTidesrc.zip. You should be able to find this file on your own PC under: C:\Program Files\Microsoft ActiveSync\cTide. At least this is where it lives by default on my win-pc. Read up on the readme.txt for harm2idx included in there. Then make sure to re-run the harm2idx program to create a more compact harmonics file and a corresponding new index file, otherwise you will not be able to load the new stations from them. You will then need to use ActiveSync to copy the new "harmonic" part files and "harmonic.idx" to your device.
My Location Is Not Listed
In a word, bummer. In "How Does This Work?" you can infer how the special data does not fall from the sky. At the time of release, this program includes the most recent data available. A more comprehensive discussion of this can be found at www.flaterco.com/xtide/harmonics.html
Note that cTide does not directly support the XML format for offsets as described at David's site. For this you need to use the tools that come with cTide. See Getting New Data.
Well, you didn't specify Portugese ports in your original question, so a bit unfair to expect us to guess that was your requirement. Are any of these ports of use?

Otherwise, have a look at the ever popular Belfield software, it costs peanuts, and you get PC, pocket PC, and smartphone versions all included in the price (about £10.99 I think)but you can download a trial version to see what you think first
Sorry Brendan, because my post location states Vilamoura Algarve, I assumed..........
have tried the neptune but does'nt seem to have the qualities of X tide. I will give the Belfield Software a look. By the way the port is Cabo de Santa Maria.
