Hi all.. I posted this reply on the other "LISTMap & Android thread by mistake.
so re-posting it here..
I downloaded the PDFMaps app to my Samsung Galaxy S6 and got couple of freebie maps of the Tas NW and SW areas. Then I got the other two, Tas NE & SE by purchase. Only about 6 bucks and they all look good on my phone and are very colourful and useful. Heck, I even discovered a waterfall with them that I hadn't logged using the LISTmap! Amazing. So all good stuff there.
But.. I discovered another thing to be careful with.
I then went back to LISTmap on the Laptop, and used it to make a pfd of the Meander Falls area, from Lake Huntsman, down to the Tiers cliffs. The scanned WMS info looks good. Then I connected my phone, to the Laptop, and copied the pdf across into the PDFMaps directory that the PDFMaps App automatically created. When I fired up the App, my new pdf was available in the list there. It looked very good as I viewed it and I thought, wow, I can do hundreds of these pdfs, chuck em on the phone, and bob's your uncle! Yes, true, you can do that, but I also discovered that each new pdf you bring up to view into the App is then formatted and tiled to suit the App and it results in 72 separate and distinct tiles being created! That's for each pdf you put in! Now, at only 25.3k per tile, that's about 1.8Mb per pdf. Ok, not too bad if you have 128Gb memory on the phone. A 21 pdf/map coverage of Tassie at the low res from LISTmap, would only be 38mb.. but the kick in the backside is.. that from then on, every time you open up Gallery to look at photos, you will see every single tile, from those 21 pdf maps shown there as a separate pic!! That's 1500 or so tile pics that just go on and on forever, as you try vainly to flick through them with your finger! Groan.
It becomes a useability hog of vast proportions. So.. think twice before you put pdfs on your phone and view them in PDFMap!
It's all great stuff, but the other drawbacks can be very onerous! Ok if you only use PDFMap and never use Gallery.
Cheers.
