<p>Hi Zoltan,</p>
<p>I have used OruxMaps for this purpose for many years now and it
used to be free with a nagging "Donate" now and then. These days
you can only donate and then install it. But it is amazing and a
small prize to pay. It works perfectly with OpenAndroMaps but also
supports online maps.<br>
</p>
<p>With the OruxMapsDesktop app you can then convert whatever images
to the OruxMaps format...there are a couple of YouTubes and blogs
available how to do that.</p>
<p>Locus Map is another popular alternative but you also have to use
a few "tricks" to convert image files to a suitable format.<br>
</p>
<p>Regards</p>

Walter,
<br>
Amazing what one finds on their doorstep, hey? :-)
<br>
You hit the nail on the head when you said "less travelled roads"
and "holiday" - that's exactly the reason I'd like to use it for.
<br>
<br>
Cheers for now,

I am amazed that Aslam has not already replied with "PDF
Viewer"...NGI actively promotes it.
<br>
<br>
Personally I have all the 250k topos on my tablet and also
upload any 50k topos (tifs work fine) of areas that I want to go
to. You can even make maps (with routes/point of interest etc
and the background you prefer) in a GIS package of your choosing
and provided that package can save a georeferenced PDF, you can
then save that on the tablet. I have successfully used this on
holiday, when driving along the "less travelled" roads -
checking my location relative to the planned route and 50k topo
images.
<br>
<br>
You certainly can see you current location and I believe you can
drop some pins. It is also free (last time I checked they wanted
to sell you maps/data, which we don’t need). Scrolling is smooth
on my tablet.I certainly would not recommend it as a spatial
data capturing app, but it certainly is good as an informal
tool.
<br>
<br>
Negatives: It crashes often on my tablet, but only when I am
doing uploads/processing. I don’t recall it crashing during
actual use. Uploading many separate files/tifs is cumbersome.
Get a good sized SD card...it duplicates your tifs into what I
suspect are tiles and/or pyramids. It is picky about the types
of tifs it consumes, but I cannot remember which...I suggest
starting with uncompressed RGB images.
<br>
<br>
Hope that helps

Subject: [OSGeo Africa] Android GPS tracking on offline imagery
<br>
<br>
Hi AfricaList,
<br>
I see that there is a truckload of GIS related Apps in the
Google Playstore.
<br>
<br>
I've just bought the new Samsung Galaxy Tab S3 (latest Android)
and would like to put some TIF format aerial orthos onto it, and
view them "at my current location" (track while I drive).
<br>
Beyond that plus zoom in/out, the only functionality I might
want is to drop a pin at current location, and add a short note
to it.
<br>
<br>
So, given this really basic, simple need, plus the billions of
Android apps in the playstore, would anyone like to recommend a
really lightweight app that I can do this with?
<br>
<br>
Regards and thanks in advance,
<br>
Zoltan
