PhotoLayer plugin - Satellite GeoTiffs with transparency

[jbruggem60]

mike,
I see that the package libwxbase3.0-0v5 installs the file:
libwx_gtk3u_core-3.0.so.0 (in folder /usr/lib/x86_64-linux-gnu)
whereas photolayer appears to look for

libwx_gtk2u_core-3.0.so.0


I'll try to make a symlink of 2u to 3u ...

[jbruggem60]

mike,


before I made the symlink:

root@idefix:/usr/lib/x86_64-linux-gnu# ls -l | grep gtk3u_core
lrwxrwxrwx 1 root root 29 Mar 24 2020 libwx_gtk3u_core-3.0.so.0 -> libwx_gtk3u_core-3.0.so.0.4.0
-rw-r--r-- 1 root root 6779624 Mar 24 2020 libwx_gtk3u_core-3.0.so.0.4.0


making the symlink:

root@idefix:/usr/lib/x86_64-linux-gnu# ln -s libwx_gtk3u_core-3.0.so.0.4.0 libwx_gtk2u_core-3.0.so.0


results in:

root@idefix:/usr/lib/x86_64-linux-gnu# ls -l | grep gtk3u_core
lrwxrwxrwx 1 root root 29 May 16 15:38 libwx_gtk2u_core-3.0.so.0 -> libwx_gtk3u_core-3.0.so.0.4.0
lrwxrwxrwx 1 root root 29 Mar 24 2020 libwx_gtk3u_core-3.0.so.0 -> libwx_gtk3u_core-3.0.so.0.4.0
-rw-r--r-- 1 root root 6779624 Mar 24 2020 libwx_gtk3u_core-3.0.so.0.4.0


but after reinstalling plugin in opencpn it still does not work, now it does not find another library:

so now I'm delving into libgeotiff.so.2 ... I'll keep you informed ;-)

[jbruggem60]

mike,


I'm not really familiar with flatpak, do you mean to completely reinstall opencpn with it's plugins from flatpak, or only the photolayer 3.3.1 plugin ? How do I do that ?

[jbruggem60]

Mike,


made another symlink, see below.

Now after restarting opencpn and reinstalling the plugin I got to see the photolayer button on the menu ! but pushing the button crashes opencpn :-( ...


/usr/lib/x86_64-linux-gnu/libgeotiff.so.5 comes from package libgeotiff5.

... and here opencpn crashed ...

Jan ...

Setup Linux Mint 20.1.
Installed flatpak OpenCPN.
Downloaded photolayer 3.3.1 (flatpak) from Cloudsmith -prod.

Success .. the dialog appears. Not tested with a lat/lon/wgs84 tif yet.

mike,


Installed flatpak OpenCPN and downloaded photolayer 3.3.1 (flatpak) from Cloudsmith -prod (file photolayer-3.3.1+3101.v3.3.1_flatpak-18.08-x86_64.tar.gz) .



This works ! At least the plugin window pops up. I now have to repopulate my charts in this new setup before further testing, but I'm up and running again. Thanks for your help !

[GordotheGrey]

Does anyone have a recommendation for a simple tool to geotag images?

As an example of the task. I'd like to be able to overlay the restricted fishing zones around New South Wales. NSW Parks publish a bunch of PDFs with a lat/lon grid included.
eg http://www.dpi.nsw.gov.au/__data/ass...Zoning_Map.pdf

I have used Weatherfax to align and overlay but the save to kap doesn't work and the overlays i create disappear after every restart.

Any suggestions?

regards Gordon

Away from my dev pc but have you looked at sat2chart?

Gordon,


you are aware about:
https://opencpn.org/wiki/dokuwiki/do...d-marine-parks

[sv_pelagia]

As long as you have accurate lat/long of a few points, QGIS will do this (and a hell of w lot more!) (QGIS is free, open source software available for many platforms.)

[rgleason]

Good point.

This would be a valuable enhancement if Weatherfax would save the coordinates with the image, so that the image can be re displayed without having to use the Image Wizard again.

This is what happens when you try to load from the weatherfax directory using "File >Open":

Hi Mike,
I use sat2chart often. Paul has created a great tool but, it doesn't do the georeference step but will create a chart after it's done

Hi BCN,
yes, I've seen that in the library and it works well.

It doesn't have NSW though ...

and that was just an example file. There are several other sources of useful info that I would like to be able to overlay or use as a chart

Other examples include the the Beacon to Beacon guides (which are are great) and small area surveys that are regularly done for some bar crossings on the way

Hi sv_pelagia,

I am trying the get my head around QGIS... the problem is the "hell of a lot more bit" it's a very big function application and I have found the georeferencer bit but not how to output a geotiff ...yet

pointers greatly appreciated

I was really looking for something small and simple ... just like weatherfax ...

regards
Gordon

Hi Rick,

Yes, the function that weatherfax provides is almost perfect.
It has a really simple georef function that works perfectly and then display the output as a layer which also works perfectly.. and I can even turn it on and off but as soon as I restart OCPN ... it's gone ...

if only it would do persistent save .... so I can select it again .. or if the save to kap worked or if it would save as a geotiff the photo plugin could handle it and sat2chart could do its thing as welll
if only ....

regards
Gordon
