Using Maprika Map Designer Tool on a PC
Q: How do I make a map myself? A: Get a .JPG copy of the map on your PC then fire up Maprika on the PC. Q: Tell me more about Maprika on the PC? A: It works very well, it is available HERE. It also requires Google Earth which is available HERE if you don not have a copy already. It is very good but there is only a windows version. Click HERE for a very good set of detailed instructions from the Maprika web site. Scroll down to the bottom half of the page to see the info for the PC version of the software. Q: What are some other thing I should be aware of? A:
When you a
save, it will generate 2 additional files, one ending in .cmap and one ending in
thum.jpg. If you upload it to Maprika, the only way to get it to your smart
phone, it will generate 2 additional files, a .jpg.tiles and a .ele. I greatly
prefer to create a map on the desktop, among other things it tells you how much
each point you entered seems to agree with the others. If one point is
totally messed up it will be obvious. How you load the .JPG file is not
completely obvious. You do not use File>Open or File>New, instead, click
on the words "Click here to select image file" in the middle of the left big
panel. The .cmap is the key file. It is a text file that can me viewed with any text editor such a notepad. Contains the name of the .JPG file. Some words of warning are in order on folder naming and updating with new maps. Folder naming

Q: What is the optimum file size? A: I have found that the .JPG file needs to be at least .5 Meg (500 Kb) I
typically save .JPG files with a compression factor of 20%, a fairly low
compression rate. If you do not understand this just go with the default. Some
images such as ones that are only 640 by 480 are only about 0.07 Meg. These sort
of files do not have sufficient detail. The big problem with these small files
is that Maprika cannot zoom in very far. The fix to this problem is to read the
file in to some picture manipulation program. On the program I use, IMMAGE >
RESIZE > Then put in something like 3000 pixels for the width and let the high
float. If the files get really big, then Maprika cannot process them. It will
just quit without an error message. Making the file smaller with more
compression will not help. It seems to max out on the number of pixels. If you
really need a large file, then process it on a PC. That is now my preferred
method for all files anyway as long as it is a file I can make public as you
have to upload the file to Maprika to get it on to your smart phone. Try
to keep the file size under 2 Megs but you can get away with 3+ if you really
need it. A good scale is something like 600 pixels/Mi or 400 pixels/KM if you are covering a moderate sized area like a ski area or city center. However I did get away with only 150 pixels/Mi for a bicycle map that covered about 40 miles by 50 miles. If I had used 600 pixels/Mi the file would have been 13 Megabytes. There are some examples of much bigger maps on their web site. The Mt Rainier Topag map is 27 MB so if you really need the size, you may be able to get away with it. You would definitely need to build the GPS enabled map on a PC. Q: What is an “anchor” in Maprika? A: It is a point that ties a point on your map to GPS data. It is generated by working back and forth in Maprika between the map you are working with and Google Maps or between the place you are at and the map you are working with. By the way, it is usually better to use the hybrid Google view rather than the default street view because information that shows up on the satellite view can often make useful anchor points. Q. Some maps are .PDF files. How do I convert a .PDF file to a JPG file A: Click HERE for a full page on how to use various programs to make the conversion.
