A.T.T. calculation plugin for REEDS almanac and Admiralty Tide Tables

[registry]

Hi all,

for easy work with A.T.Tables, published in REEDS or in Tide Tables, i've created small OpenCPN plugin.
It allows to calculate tides on secondary ports having data from standard ports and differences of secondary ports how it is suppose to be done manually on paper.

Plugin is here: https://github.com/registry/admiralty_tide_tables_pi

Idea is simple: I want to simplify tedious part of tide calculation based on A.T.T. -> calculation itself.

Having REEDS for a given year, i do actually have most up-to-date calculation for most of ports and marinas, covered by the almanac. Problem is only the calculation.

Sofar i can easily type-in the data for some standard port and differences for secondary port of interest, press "calculate" and get my tide for secondary port at given date. Agreed, further work on this tide ( tide at given time, time or required depth and and and ) has to be done manually, but for the beginning it is already something if one has tide for secondary ports.

Input form of the plugin has a form and acronyms like it is in A.T.T or Reeds for simplicity.

For further ideas would be collecting calculated data in some offline/online data base so that one has to type in tides and differences only once... but it is not done yet.

This calculated/typed-in data could be shared via ... some file in same git repository or via some online database - don't know what is better.

If some one wants to contribute -> you are welcome.
If plugin gets published on opencpn page/plugins -> nice.
if someone wants to take over its maintenance and further development (without removing essential part -> working with Reeds/A.T.T ) -> great (i don't have much time to invest into it)
Feature requests/comments/improvements suggestions i will read, but do not promise to react on them immediately ( i don't have much time to invest into it)... only if they will be useful for my own usage while sailing... sorry for that.




Cheers,
Pavel


P.S.
I've developed it havin up-to-date opencpn build out of git/master.
Plugin is based on demo_pi, which i have taken as an example and modified it so long, till it started to calculate tides.

[registry]

thnx for feedback... i will obviously need it

i'm not familair with wxWidgets -> just try like "monkey sees, monkey does"

i've removed sag fault causing reference...

just to sync up
wx-vconfig --version: 3.0.2
opencpn version : head of master
g++ --version: 5.3.1-14ubuntu2.1
ubuntu 16.04 LTS
4.4.0-24-generic x86_64 GNU/Linux

[registry]

For the future...

what at least should i do, so one considers to publish this plugin on opencpn.org ?

icons? docu? win/mobile/linux/macos builds?

[nohal]

registry...
When reasonably confident that the plugin is ready for general usage, tag a release version in your github repository and let me know to pavel_at_kalian_dot_cz and I will get back to you if some problems are blocking the release.
No need to do the builds for any platform yourself, I do them anyway before publishing the plugins to make sure they are not completely broken...

roger that

P.S.
My real name is apropos is same :-) cheers... but online is online ;-)

Hi all,

little update.

I've added IO.
Now one has to input data for standard or secondary ports only once, save it and it gets loaded by next start of opencpn automatically.
Format of files is not stable yet. I have to make a round of field tests wheather it is usable and check calculation.

rgleason tests it on win as standalone build (i use linux and build within opencpn build system)

any another tests (on another systems/configurations) are welcome.

Small road map:
1. Polish UX and behavior of all form elements
2. Improve io format.
3. Connect Standard and secondary ports. (issue: A.T.T. lists numbers of ports, REEDS - no.. ).

Further ideas (which i might or might not do):
1. Add some kind of exchange data of stored ports with community to make it downloadable . In this wey data base of tide data from A.T.T. and REEDS will grow much faster and gets available for more people.
2. Add support for tide curve for standard port, so one can do such thing like "at which time one has enough water depth to pass a barrier" or similar.
3. ...

cheers,
registry

@Pavel (Registry)
[Unfortunate circumstance here as "Pavel" is another developer and "Registry" is the main developer]

Can you add your tables in a file for this plugin and make an 'import' feature? It would be easier to test and less work ? also someone might find them useful and add to the file.

Having REEDS for a given year, i do actually have most up-to-date calculation for most of ports and marinas, covered by the almanac. Problem is only the calculation.

[rgleason]

Here is what the plugin looks like without entering data. I don't have time to mess around entering Admiralty Data as that is not my sailing area.

The Table appears to work, but I have not tested it due to lack of data.
I have not tested the Export function. It would be nice to have an import function with some data to test with.

This new plugin is built and packaged for Windows at
OpenCPN Beta File Thingie rguser rgpass
Look under the 4.4 directory or the 4.2 directory.
admiralty_tide_tables_pi-0.1-ov4.2-win32

Whoops... now I read

but I think I have the most recent git fetch.....????

[rgleason]

The git version I have is
* master f549b3b fixed forgotten array

@Pavel [registry] There does not seem to be any date. Or import function.

[skipperearly]

Has anyone compiled a consolidation of various user data and how is it to be done?
- or is this plug-in maintained only for US?

I am particularly interested in Biscay South till Gibraltar and Malaga.
Any advise on where to get this data for use in ocpn is appreciated.

[rgleason]

In brief, No. If you read the plugin provides a structure and forms to import data, but no data. It would be nice if someone took yhat task on and shared it with everyone. Read below, you can import the data.

[rgleason]

Added to Beta Plugins
https://opencpn.org/wiki/dokuwiki/do...gins:admiralty

[registry]

I will get some work done for thius plugin when i will prepare my next "English Channel" trip, like next summer.

Before that to loaded with another things and not-tide relevant sailing routes like on Baltic or Mediterranean sea

As i've told - would be happy if someone takes over more intense development and mainaince of this plugin which i observe being useful for the navigation :-)

Sort of works on Opencpn 4.8.0 . Calculated data looks OK, but save the data and Opencpn crashes either when you try to exit O or disable the plugin.

Pity, would be a very useful check for web tide data or when you don't have any web access. Bit too much work to input all the data every time. I've struggled to create something similar in PHP but gave up, PHP is a bit non intuitive for a non programmer like me

It would be really useful if someone were to pick up the ball with this one, if the save file was a human readable csv file or something then we could all add data. Standard port data looks to be fairly easy to get hold of on the web but I couldn't find any secondary port offsets online, looks like you might need to splash out on Reeds or the Cruising association almanacs for that
