Maps and GPS - Project Maps for Memory-Map (M4MM)

Project Maps for Memory-Map (M4MM)

Introduction

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;

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, teh technical documentation in the programming section.

OziExplorer maps

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.
- Installation files M2J (download > unzip)
- Documentation files M2J (download > unzip > install)
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!

Mobac maps

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 may 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 MAP-file.
The current (experimental) version 0.2 converts this MAP-file into a JPR-file.
- Installation files Mob2J (download > unzip)
- Documentation files Mob2J (download > unzip > install)
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.
- Installation files G2J (download > unzip)
- Documentation files G2J (download > unzip > install)
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.
