TACKLEFEVER

Ich habe nochmal in meinen Unterlagen nachgesehen, denn wir hatten in der Beta-Gruppe dazu einen Diskurs. Es ging dabei seinerzeit darum, bis zu 4 Raster übereinander liegend darstellen zu können (etwa als jeweilige Themenkarte) und zwar über den Befehl DVOR in der Atlas Description.

Die Lösung liegt darin, den Rasterkartentyp "Shaded Relief" zu wählen, den dieser ist für die Vektordarstellung, auch mit Transparenz, ausgelegt. Ich habe das auch nochmal an meinem HDS Gen3 gegengetestet. Es kann allerdings sein, dass bei den einzelnen Geräten je nach Markteinführung und Firmwareversion Abweichungen möglich sind, weil diese Funktionen in dert jeweiligen Firmware implementiert sind. So war es vor einiger Zeit bei ladenneuen Geräte möglich, dass diese trotz Eignung dafür bestimmte Elemente noch nicht darstellen konnten, was dann etwas später durch Firmwareupdates beseitigt wurde. Bei neueren Geräten würde ich das eher nicht vermuten.

Dein Problem würde ich auf die Schnelle mit dem anliegenden Screenshot bei der Vektor-Kartenerstellung angehen. Die Textblase gibt dazu weitere Erläuterungen.
Die mit entstehende at5.xml muss dann natürlich mit auf die SD-Karte.

You are correct, there is nothing wrong with adding a small font label with the campsite number.  I do that with the printed version of the map I take as a backup, prepared with QGIS.  I am just stubborn I guess seeing how my Gen1 Hook handles things differently and I prefer less clutter.  If I were to add the campsite label, I would limit viewing to certain zoom levels so the text would disappear zoomed in and not be a distraction while fishing. 

I wish the new Eagle 4" had charting capability, but it does not.  I find that size to be ideal for low power applications in paddle sport fishing.  It would compete well with the Garmin Striker4CV if it did have GPS.  Then again, Garmin locks things down, so you cannot do anything remotely close in regards to custom mapping, only live contours.  Long live IMC!

I will probably upgrade to the Eagle 5 at some point before next spring.  Hopefully there will be a sale coming up.

To be honest, I have not messed with map categories, I am not even sure if my units support it, probably, but I have not looked.

fjordfischer thank you for the prompt reply. I value your thoughts and ideas as your IMC knowledge is vast and your responses are super helpful.

I have kept my campsites as unlabeled points to keep the map clean and uncluttered.  Currently I use three different colored icons for different types of campsites (Open, Closed, & Unverified) and all three are just a small dot, again to reduce clutter.   It doesn't sound like there is an option to change the behavior on an NOS system so that the hover over (cartoon bubble label) displays something other than the MIN_CAT value.  It is but a minor inconvenience, as you say the detailed info can be had with a couple more clicks. 

The map I am preparing is for a canoe fishing application with an off grid setup.  For this reason, a unit with a small screen is preferred to keep battery usage to a minimum.  I have a 5" TI unit, which works well for testing, but is still a bit more power hungry than I would like.  The unit I currently use in the canoe is a Gen1 Hook unit with a 4" screen. The unit is a bit slow at times, but I have become accustomed to it's quirks. (Let it boot fully like an older computer before you try to use it.)  I also have a Hook2 5" unit, but I have been reluctant to use it based on the push in connectors, inferior SD slot and the fact that Raster maps are not enabled. I am considering one of the new 5" Eagle units as the connectors have been improved with twist locks and I would also gain Genesis live mapping, but still no Raster support.  I tested one of these units at a local retailer and I was able to display my custom map and the interface seemed nearly identical to my hook2 unit.  I wish the HDS models were available in a smaller screen size for this application as they seem to have more options.

Thanks for confirming my suspicion that the excessive MIN_CAT entries were likely causing system issues.  I did not see this specified in the documentation, but it makes sense.

I have played around a bit with the attaching a photo to a point, but have not implemented it in my map.  My 1st Gen Hook unit does not support it, but it does work on my TI, TI2 and even Hook2 unit. It is a cool feature for sure.       

I have found this forum post to be one of the most helpful in understanding how to work with attributes in QGIS for IMC usage.  In my opinion it is a shame that it is buried in an old Reefmaster thread as it directly relates to IMC.  Perhaps it would be appropriate to start a thread under the IMC documentation pointing here, as I think it would be helpful for others to see.

I have a related question to POIs.  I have a few shape files in my map that I use the INFO_BOX attribute to link to more information about the point.  On my gen 1 hook unit, when I hover the cursor over the icon I can see the detail contained in the INFO_BOX without actually pressing a button to select it.  When I load this map in newer units (TI, TI2, Hook2, Eagle) and when I hover over the point I see the information contained in the MIN_CAT attribute.  If I select the point I am able to drill down to the detailed INFO_BOX information, but it takes a few more button/screen presses.  I am guessing this has has to do with the differences between the Indigo-Violet operating system and the NOS operating system. 

I much prefer the way the Gen1 Hook handles this and was wondering if there was a way do accomplish this on a NOS system.  I did try to copy the information contained in the INFO_BOX to the MIN_CAT attribute.  This works on a limited basis it seems.  There seems to be a limit to the number of unique MIN_CAT attributes you can have in your map, as when I loaded several thousand POIS with unique MIN_CAT values the resulting map would not load and caused my unit to reboot continuously. I believe I exceeded what the unit can handle.  Are there any work arounds to this? 

The POIs that I am using relate to campsites that each have a unique number and rating that I have stored in the INFO_BOX.  For now I have sorted the campsites by rating (1-5) and have copied the rating into the MIN_CAT attribute.  This way I can see the rating when I put the crosshairs over the POI,  but I do not know then number until I select the POI detail.  It works, but is not ideal.
