What is Localizer ?
Localizer is a vector and image based map viewer for Qtopia based PDA devices like the Zaurus. It's mainly focused on city maps and maps for exhibitions, expositions, congresses, etc. It can use vector graphics to draw your maps or it can use pictures (i.e. satellite images of cities). In the latter case, it can store images at multiple resolutions and let localizer decide which one to use in each moment. Localizer has an smart memory manager which will load/unload from memory the images that better suit the used zoom factor and the memory usage.
You'll need the following three files if you just want to install localizer to try it. The localizer_1.2.0_arm.ipk file is the binary and some examples of exhibitions. If you want to try the city map, you'll also have to install the localizer_example_data* packages, which include the aerial photographs for the map. Note that everything in localizer is vector based, except those aerial photographs (which take a lot of space even if they're in jpeg format, and that's the reason why I have splitted them and made available separately).
Note about the installation:
mv /opt/Qtopia/pics/localizer/MalagaMap $CFCARDPATH/MalagaMap
2) The Zaurus package manager will abort silently if you don't have free space on your partition to install those files and you'll think that it's correctly installed, but then not all files will be there. Note that you'll need at least 4700 Kb available ( 5 Mb wouldn't be bad just to be sure) for the installation. After that, localizer and all the complete examples will take 2550 Kb. (if you want just localizer to use with some other maps, you only need the binary file, which takes 146 Kb.).
To install localizer with the minimum space available (4.7 Mb), follow the next steps:
1. Copy localizer_example_data1_1.2.0_arm.ipk to your Zaurus, install it and remove the ipk file.
Please note that if you don't follow the above steps, you may need up to 6300 Kb available for the installation instead of 4700 Kb !
Legal noteLocalizer is not yet GPL. I'll publish the source code under the GPL license if there's enough interest. In other case, it will remain freeware (free to distribute, copy and use, but just the binary, docs and examples).
