TACKLEFEVER

So I have been working on a Google map of my area. Map shows up fine on Lowrance at all resolutions. I have decided to add shapefiles for navigation lined, buoys and obstructions that I have taken from NOAA and converted into single shapefiles in QGIS.

I have created all of those with correct ( I think ) attributes but when I add them to the AT5 files on my SD card, the navigation line shows up below the google raster map. The point icons for buoys, obstructions, etc. show up fine above the map image. I have messed with multiple advanced setting and attributes and cant seem to figure this one out. Any help would be appreciated.

When I turn off shaded relief on the Lowrance unit, I can see the line and buoys. Once I turn on shaded relief I can only see the buoys. The line is specified as an Area and not a line.

My line attributes are:
L_LIMIT  -  Value  - 1
U_LIMIT  - Value - 15
Layer       -  Value - 1
Color      - Value  -14
MAJ_CAT  -  Value  - Nav Line

In advanced options in Vector Mode, I have Group Geometry checked although I have tried it with it unchecked as well.

Any help would be greatly  appreciated.

Hello, Hopefully I can keep this short and someone can help.

I am creating a very large map of the coast where I live. I am using the Google Hybrid Map from SAS Planet and have downloaded the KML's from zoom 7-18 in separate zoom folders. I then created the jgw files in each folder. So far, so good.

Now, when creating the At5 files I have done so individually at each zoom level with corresponding resolution. zoom 18-1, 17-2, 16-4......8-1024, 7-2048. The issue is size. at zoom 18 with resolution of 1, those AT5 files are over 100G just for zoom 18. Now I dont need everything  to have that zoom capability or that high of a resolution so I have done the entire map from zoom 7 to 16 at resolutions 2048 to 4. I end up with file size being around 8G up to zoom 16. Now I do want areas of the map to be able to zoom into 17 and 18. I created small sections of zoom 18 at resolution 1 and then created slightly larger areas for zoom 17 at resolution 2.  Zoom 16 covers the entire map.

Now when I do this with a small section of the map, zooming in and out looks just fine even in areas that dont have the zoom 17 and 18.  when I do much larger sections, all the areas that dont have zoom 17 or 18, just turn black.

I thought about just removing zoom 17 and 18 and creating zoom 16 with resolution from 1 through 4, but even that is too large.

Is there something else I can do to make this work? Anything I should change? How do I make really large maps without the zoom on my lowrance turning black at a high zoom levels or without being too large of file size?

Any help would be greatly appreciated.

Sorry!

Nach längerem Üben und Suchen habe ich die Einstellung beim HDS Pro gefunden.
Im Menü User Interface > Cursor bei einem HDS Pro Gerät ist die Einstellung verfügbar und aktivierbar.

Das Menü wird automatisch auch beim HDS Pro ausgeblendet, wenn 15 Sekunden lang keine Eingabe vom Benutzer erfolgt.

Added.

Welcome in the beta group.

Wer Programme wie RM nutzt, kann auch auf Quickdraw-Daten zurückgreifen. Unter diesem Link:

https://github.com/interlark/qdc-converter/blob/main/README.en.md             (englisch als Sprache einstellen)

kann man sich ein kleines Programm herunter laden, welches die Quickdraw Tiefendaten in das csv-Format umwandelt und in RM problemlos verwendbar ist (Hinweis: ggf. X und Y vertauschen, sonst landet man in Äquatornähe).

Üblicherweise nutzt man in Garmin andere Formate für die Daten aber ich habe schon des Öfteren den Fall gehabt, dass ein Garmin-Nutzer nur noch die Quickdraw Daten verfügbar hatte.

Zusammengefasst bedeutet das, dass man Daten folgender, relvanter Marken in RM einzeln oder gemeinsam nutzen kann, sofern man die dafür erforderliche Software zum Konvertieren besitzt:
- Lowrance, Simrad,B&G (alles Navico), inkl. Genesis Live
- Humminbird, inkl. Autochart Live
- Garmin, inkl. Quickdraw
- Navionics - ausschließlich Sonarchart Live
