<p>Hi Peter:</p>
<p>Generate the map you require in the field using the print
composer. In the items window on the right hand side of the
standard composer window, select the Composition Tab and check the
save world file option in the export settings. <br>
</p>
<p>Save the pdf of the map and load into Avenza. <br>

<p class="MsoNormal">Are there any updates to the threads of
2015/2016 regarding QGIS producing georeferenced tifs or pdfs
for loading into Avenza? I am a newbie to QGIS (Madeira 3.4)
and while I have succeeded in producing a correctly
georeferenced tif file via Raster>Conversion>translate,
this only works on one layer. The three other methods I can
see to export or print a pdf or tif do not produce a correctly
georeferenced file in Lats/Longs using GDA94Z50. The file
according to Avenza is ~54deg and 89deg south and west of
where it should be.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I am starting with a non-georeferenced
raster which I put through the georeferencer with 6 GCPs and
several experiments of transformation types, settling on
polynomial 1. The process produces a tif, pdf, and loads back
into the main window. The main window raster is georeferenced
perfectly, so wouldn’t you think the other output would be
too?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The correct method should be to use Print
Layout, produce a map with all the layers from the main
window, and export as an image or pdf. This might work if the
map units were real world and not mm.</p>
<p class="MsoNormal">The fall back should be
Project>Import/Export>Export Map to Image or pdf from
the main window, but that doesn’t work either.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I hope the solution is obvious and I have
overlooked something simple. Any guidance appreciated, I like
to take my maps out into the field.</p>
