Hi - I don't seem to be able to get this plugin to work with the new 3.2 version of QGIS - has anyone done any work to get this functionality into the 3.2 version? or can offer any suggestions?

I'm trying to export a map using the GarminCustomMaps plugin for use on a Garmin GPSMAP64s. The area of interest (AOI) is a Canadian forest management unit over 1MM hectares (10,000sq-km) in size.

I've read the tips in the export dialogue, used the highest recommended scale factor (along with countless other iterations with other variables), but no matter what I try, the resolution on the GPS unit is very low to the point that it can't be used. Sometimes the GPS doesn't display anything.

My organization has traditionally used a program called Mapwell which outputs IMG files which scale nicely on our GPS units, but the software is clunky and often doesn't hold our symbology choices when it gets to the GPS.

Has anyone encountered this? I was thinking it might be the size of the AOI, but I tried a much smaller AOI and the quality wasn't much better.

Thank you!
Jon

I work on win7 64 bit and use QGIS 2.18.10 and 2.18.11 both 64 bit.

After installing plugin GarminCustomMap v. 1.2 it makes QGIS crash and makes a minidump when teminating the program.
After uninstalling the plugin the program crashes again one time but after restart there is no problems.

\GarminCustomMap.py", line 554, in run
t_file.GetRasterBand(1).WriteArray(t_band_1)
File "C:\PROGRA1\QGIS31.4\apps\Python37\lib\site-packages\osgeo\gdal.py", line 2653, in WriteArray

raise ValueError("expected array of dim 2")
ValueError: expected array of dim 2

To avoid issue #9, I turned off "Skip production of empty tiles". Now instead of throwing an error at line 551, it throws an error at 554.

An interesting hint from Mike on JNX format:

"The KMZ Format is very slow. So if you want to show maps its cool to use JNX format.

Todo this A. Whiter added a Firmware Patch and also has some Format Information about JNX.

Actually I can download WMS Tiles using Mobile Atlas Creator and use tools to convert it to JNX.

Last but not least you could create IMG files, but the easiest way would to create JNX Files.
Also note: If you load the JNX Files to your Garmin, you can see it in the Basecamp Software, too!
Very cool."

A high resolution map canvas export (to GeoTIFF) could be easily converted to JNX using mklandkarte

Unable to use the plugin. Error argument 1 has unexpected type 'int'

I have tried even with a simple map of a vector gpkg of points and with/without esri basemap.

Thrown as WARNING.

Is there a manual I didn't find? I think I'm making some basic mistakes. I'm trying to make a topo and boating map of the entire Yukon Territory. I've downloaded about 7 vector files from http://mapservices.gov.yk.ca/GeoYukon/ . Each layer is 200MB to 1.5GB. After downloading the shape file, I unzip it and import it using Layer>Add Layer>Add Vector Layer. I did this for all of the files and then cropped them to the political boundary of the Yukon Territory. At this point, I'm showing the cropped layers (the original layers are still in the layer windows, but not displayed). Everything I want is visible and I'm zoomed out to the full extents of the map. The file must be huge since every click takes a long time to process. I go to Plugins>GarminCustomMap>Create Garmin Custom Map from map canvas. What specifically is a map canvas? I left all of the inputs as the default except the zoom, which I chose to be 12 as that was the maximum zoom for <=100 tiles. The export says it finished successfully with 16 tiles and 48 rows. I ended up with a kmz file that is 881kB. For comparison if I were to buy the Backroads Map Book GPS file it is 1.6GB.
I just installed QGIS 3.6.3 and GarminCustomMaps yesterday.

Any help would be appreciated! Thank you.

when using this plugin with the newly released version 3.10 of qgis export maps does not work because line 493 in GarminCustomMap.py (iface.messageBar().pushMessage("WARNING", "The number of tiles is likely to exceed Garmins limit of 100 tiles! Not all tiles will be displayed on your GPS unit. Consider reducing your map size (extend or zoom-factor).", duration=5)) produces an error.

If this line and line 492 is commented out it generates maps without problem.

Not sure if this check is needed, possibly a checkbox to select which kind of Garmin is used (100 or 500 tiles) and an appropriate messages would be better.

The following link no longer works:

Hey, I've found the reason why my raster layer background is not shown in the kmz file. Whenever i use a zoom factor (for example 10), the raster layer appears in the top left corner as a small tile. The rest of the tiles just has a white background, with the vector layer in front.

But if i use a zoom factor of 1, the raster is shown perfectly fine with all vector layer on top. This is okay for my current work, but now the resolution is not the best. I´ll play around a bit more, but maybe someone has the same problem. Just use the zoom factor 1 and then maybe load more kmz files on your garmin device...

while trying to export a map for my GPSmap64s i wanted to follow the recommendation of the plugin and use a zoom-level of 39 only to find out that there is a hard limit of 25 configured in GarminCustomMap_dialog_base.ui.

Setting this to a higher maximum i was able to sucessfully generate and use a map on the gps.

Is there any reason why this limit was set to 25?

As published here: https://plugins.qgis.org/plugins/GarminCustomMap/, click "Download latest", the resulting file downloaded to OS-X 10.11.6 fails to unpack w/ "The Unarchiver", which claims to be looking for other parts of archive. Some unzip tools will open GarminCustomMap-1.2.1.zip, but apparently not the one used internally by QGIS. I even changed the OS default to one that worked, no joy. The result is that I've not yet figured any way to install the plugin via the "official" method.

I'm trying to export for a gpsmap64s. It allow 500tiles custom map.
when I'm trying to export I get the warning:
"The number of tiles is likely to exceed Garmins limit of 100 tiles! Not all tiles will be displayed on your GPS unit. Consider reducing your map size (extend or zoom-factor)."

if the tiles number for <=100 is 14, I have to chose 10 tiles for have no problem kmz.

Makefile is old for QGIS 3 and should be updated. Some issues with make package : when the created zip filed is uploaded an error appears:

Hy,

When i used dual screen, the raster is not scaled (vector are ok)
Exemple: The best place of the red zone near the river

The kmz: the red zone vector is ok but the raster is not scaled on the river we can see on the google map view

I used QGIS 3.22.5 on Windows 10

Thanks

Hy,

I used QGIS 3.22 . I have an error message when i want to load this extension
TypeError 'QVariant' object is not subscriptable

Thanks

PS: it seems to come from my test profil

Line 527 should read

if r == int(n_rows) and n_rows_rest > 0:

not

if r == (n_rows) and n_rows_rest > 0:

otherwise the condition will never be met and max_y_ext may be too large leading to lines 546 to 548 returning a NULL value which will through an exception later on.

when exporting with zoom for device with 500 tiles, I get this error:

2019-02-27T23:04:50 WARNING Traceback (most recent call last):

and no file is produced.

First, nice plugin, thanks!

When running QGIS in debug mode (where ASSERTs will kill the app), the plugin causes QGIS to die when the zoom != 1.0. That's because the painter's DPI doesn't match the output DPI.

The way to fix this is to declare a DPI in the QImage used to paint the map:

                # create output image and initialize it
                image = QImage(QSize(width, height), QImage.Format_RGB555)
                image.setDotsPerMeterX(target_dpi / 0.0254);
                image.setDotsPerMeterY(target_dpi / 0.0254);
                image.fill(qRgb(255, 255, 255))

Maybe a corner case, but for a mainly black map canvas the following error pops up:

Traceback (most recent call last):
File "C:/Users/stefan.blumentrath/AppData/Roaming/QGIS/QGIS3\profiles\default/python/plugins\GarminCustomMap\GarminCustomMap.py", line 551, in run
if t_band_1.min() == 255 and t_band_2.min() == 255 and t_band_3.min() == 255 :
AttributeError: 'NoneType' object has no attribute 'min'

Not sure exactly since which version, but with 3.22 and 3.24 the scaling of a raster map with a Zoom-Factor =! 1.0 no longer works.

Solution: Comment out line 345 in GarminCustomMap.py

This line:
345: mapSettings.setOutputDpi(target_dpi)

is not needed and makes the map not being scaled (with all but the original canvas being white).
