Maps for Memory-Maps project (M4MM)

Introduction M4MM

The purpose of this project is to make exiting (calibrated) maps accessible for Memory-Map (and Fugawi) with some dedicated applications.

The project is split in two parts; a "How to use"-part and a "How it is was build" part (this web page). In the "Who to use" part you will find the downloads and the functional documentation. On this page the more technical (programming) details.

Sub-projects

• MAP data to JPR (m2j) converts OziExplorer MAP-files in to JPR-files.
• Mobac MAP data to JPR (mob2j) converts Mobac MAP-files in to JPR-files.
• GDAL data to JPR (g2j) extracts georeference data  form GeoTIFF- and GeoPDF-files and creates JPR-files based on these data.

The development of the applications above were ceased in favor of an application, which includes their functionality (M4MM).

Application Maps for Memory-Map (M4MM)

The current versions of M4MM are 0.7.0 (beta-release/32 bit/ceased) and 1.0.0 (formal release) contains the following functionality:

• Viewing and printing georeferenced data from GeoPDF-, GeoTIFF- and MrSID-files.
• Extracting georeferenced data from GeoPDF-, GeoTIFF- and MrSID-files and creating JPR-files with these data.
• Converting MrSID-files into PNG-files.
• Viewing and printing georeferenced data from OziExplorer and MOBAC MAP-files.
• Extracting georeferenced data from OziExplorer and MOBACMAP-files and creating JPR-files with these data.
• Converting OziExplorer OZF2- and OZFX3-files into PNG-files.
• Viewing, editing and printing JPR-files.
• Extracting specific meta data from PNG- and TIFF-files. The size of the image file is restricted to 2 G byte of pixel information. 
• Viewing PNG- and TIFF-files.The size of the image file is restricted to 2 G byte of pixel information. 
  
• A DPI calculator.

Both versions were released with all the code and technical documentation. The code has some internal documentation. 0.7.0 was build with Visual Studio 2019 (32/64 bit) Community and 1.0.0 was build with Visual Studio 2022 (only 64 bit) Community.

Challenges

The applications were built as a Windows Forms App (.NET Framework ) in Visual Studio 2019 Basic. The code is depending on features of this template (I know by trial and error).

• Reading and writing text to a file using the "My.Computer.FileSystem" object.
• Deleting an existing file using the "My.Computer.FileSystem" object.
• Testing  the existing of a file using the "My.Computer.FileSystem" object.
• Retrieving user "documents"- and "temporary"-directory using the  "My.Computer.FileSystem."SpecialDirectories" object.
• Splitting a string into substrings using the "Split" function.
• Using GDAL functionality by calling a "Shell" command.
• Converting MrSID and Ozi maps to the PNG-format.
• Extracting some meta data form images.
• Printing the content of a file/text string.

You will find some pieces of code  in the frame to the right.

Old versions

Older versions of the project M4MM were remove from the website; they were obsolete. Only version 0.2.0 (with the separate applications M2J, G2J and Mob2J) are available, they support GDAL 2.x.x and QGIS 2.x.x.

Future

The upcoming challenges:

• Implementing more map projections.
• Refining print function
