Project Maps for Memory-Map (M4MM)
The purpose of the project Maps for Memory-Map is to open more sources of exiting maps for use with Memory-map by converting the exiting georeference data. The conversion will be done with some little Visual Basic applications. This prevents al lot of retyping, cut/past actions, recalculations and, for most, (lots of) errors.
At this moment the project has three branches;
- MAP data to JPR (M2J) which converts the the OziExplorers georeference (MAP-)file to a Memory-Map geo-reference (JPR-)file.
- Mobac MAP data to JPR (Mob2J) which converts MAP-files created by Mobile Atlas Creator to a Memory-Map geo-reference (JPR-)file
- GDAL DATA to JPR (G2J) which extract georeference data form GeoPDF- and GeoTIFF-files and converts them to a Memory-Map georeference (JPR-)file. The extraction of data is done with GdalInfo, a part of the Gdal suit.
Although the applications were designed to use with Memory-Map, they can be used with Fugawi (it uses just the same JPR-file).
The project is split in two parts. In the Memory-Map section of this website you will find the "How to use"-part (this page). In the programming section you will find "How it is was build"-part.The project documentation has a similar split. The "Quick Start" and the "Workflow an manual" documents you will find on this page, the technical documentation in the programming section.
The next step in this project will be an integration of M2J, Mob2J and G2j in an application application called M4MM.Return to top
An OziExplorer map consists of two files, a image file and a
georeference file (MAP-file). The application M2J extracts all the
necessary data and translates them in to the JPR-file format. The
current (experimental) version 0.2 he some limitations: the map datum
will be reduced to WGS 84, NAD 27 and NAD 83 and the projections to
Mercator, Transverse Mercator, UTM and Lambert Conformal Conic. More
map datums and more projections are on the wish list.

M2J doesn't convert the native OziExplorer image files (*.OZF, etc.). To do so you need a third party program. I'll put this option on the wish list too!
The Mobile Atlas Creator (Mobac) is a universal Windows application
which extracts data from several online topo maps and converts these
data into offline maps for many offline map applications (Android and
IOS too). One of the options is to create maps for OziExplorer. Mobac
generates an image file (PNG/24 bit color depth format) and a
The current (experimental) version 0.2 converts this MAP-file into a JPR-file.

Before using the image file in combination with Memory-Map the color depth has to be reduced to 8 bit (256 colors).
GeoPDF and GeoTIFF maps
GeoPDF and GeoTIFF maps have their one "On board" georeference data.
G2J uses the function GDALInfo of the GDAL suit to extract these data. Before using
G2J you must install the GDAL suit. I personally installed GDAL as a
part of QGIS,
which installation is strait forward. The current (experimental)
version 0.2 converts only the necessary georeference data into a
JPR-file. It can't handle the map collar (NEATLINE). This issue is on
the wish list.

To extract the image of a GeoPDF-file you need a third party application. PDF-XChange Editor is a good option. In the "workflow and manual" you will find some directions.
Pre release Maps for Memory-Map 0.5
Maps for Memory-Map (M4MM) is the first release witch integrates
M2J, Mob2J and G2J (all their functionality). This version is able
handle a NEATLINE and has the possibility to convert Ozi AZF2- and
OZFX3-maps. Be aware it is a pre release.
