Chart Object Search plug-in

[nohal]

Gilletarom...
Not sure I understand. Locally what?
Just use the charts and the database will get populated in your obvious area of interest.

Hi all...
I have prepared a new testing version for Windows, which should fix the occasional crashes of OpenCPN on exit. Please, especially if you were affected by this problem, get it from Download opencpnplugins from SourceForge.net and let me know if the problem is solved.
(New "full" release for all the platforms due in a couple of days.)

Thanks

Pavel

Pavel,
Worked like a charm until the last git update this morning. Now a crash on "show on chart"

Nothing in the logfile.

There used to be a seperated thread for chart channing, wich is not there anymore.
Working under Gentoo linux
O is also the latest git.

Reason is: wxString::Format() has wrong datatypes in function FindObjects() since last github changes.
This is very often observed when using wxWidgets by programmers.

Dirk...
Wrong order of the parameters. Don't code at 3 AM

Pavel

[rooiedirk]

Works again. Thanks.

Pavel,

A very useful tool, that I am sure will grow...

I am wondering, if there is a way to search for objects, that have no known name attribute, just based on object type (some distance limit would then become very much needed)?

An example would be searching for marked anchorage areas, or for caution areas nearby...

I tried some regular expressions, too...

Thanks for the nice plugin!

Pjotr...
Distance limit is already implemented. The whole implementation is limited to named objects (and _texto for CM93) and I currently don't plan to extend it, although it is technically trivial to implement.
Regex won't work, what will is SQL LIKE syntax.
BTW, in the latest code I implemented import of CSV data, so you can populate the database with pretty much anything you like. And the DB under it is SQLite, so you can play with the data using any tool that supports it...

Hi all...
Objsearch_pi version 0.5 has just been released. Adds ability to limit the search range, import of CSV data and a scan function which automatically flies over a selected area at different scales to populate the object database.

TIA for your testing feedback.

It's awesome!

A minor feature would be that you could double click an item in the search result to show it on the chart.

Tested on Mac: The dialog in plugin settings won't close.

I just installed the Chart Object Search plugin. Great feature--I've been wanting this for a long time!

One small usability feature you may want to add: when I hit the "Show on chart" button, it always changes the scale to 135600. It would be nice if it could keep the same scale as was being displayed before you hit the "Show on chart" button.

Also, is there any way to activate the plugin with a ctrl-F keyboard shortcut?

Thanks!

Jim

[Baikal]

nohal, when there is support for finding names in the national language?

[rgleason]

objsearch for ov50 Beta is completing chart searches OK,
however it is sensitive and prone to crashing 4.99.1408.

Particularly if the program happens to be in draw route mode and at other times when trying to "Show a location on a chart".


It needs some Rx I think to be really usable.

[DavidBurch]

Thanks for this very useful plugin.

Is there a way to add objects manually to the database?

Yes, the plugin has it's data stored in a very simple SQLite database so you can use any client that can work with it to add, delete or modify the data.

You can also import any data on the Database Maintenence tab in the plugin preferences dialog using a CSV file with the following columns:
Latitude(floating point number),Longitude(floating point number),Object name(string),Feature name(string),Source name(string)
