How to change mif / mid gis data format?

I am working on an application (.net 2.0) that uses the mif / mid data format to display GIS data. I need to find a way to edit these files using some kind of editor (outside the application). I googled a lot, but could not find anything suitable (Map Maker worked, but did not display labels from the middle file). I see the following solutions (in order of preference):

  • Find an editor that allows you to edit mif / mid format correctly. Which one?
  • Find an editor that will allow you to edit some other format , and you have conversion utilities to convert to this format and back to mif / mid. Which one?
  • Find an editor that allows you to edit any other format , and conversion utilities - convert it once to this format . In this case, I will have to write my own parser. I do not like this idea :).

Free editors are preferred.

Thanks!

UPD 1 I forgot to mention that I need to load medium Unicode files or at least specify a code page. This is why, for example, the OpenJump plugin does not work (I think)

UPD 2 This seems to be a real problem. Most tools either do not mif at all, or do so in read-only mode. Anyone with real MIF read-write experience?

UPD 3 In this update, I will track all my attempts to solve this problem:

  • OpenJump - the plugin could not load non-ascii code. Unicode loading failed

  • QGIS - the downloaded MIF file, but could not save it - the function could not be saved. I am not sure, but it does not seem to support the recording mode for MIF. I tried to save the selection as a form file. Later, I could not convert it with an OGR level converter - failed with access violation.

  • MapInfo Professional 10 could not load the MIF file with access violation.
  • GV sig does not support MIF format.
  • UDIG does not support the MIF format.
  • WinGrass did not start on my PC.

TBC ...

Free Conversion Tool: OGR (also see Mitab )

Free GIS editors (who can read MID / MIF): Quantum GIS , OpenJump , others *

GIS Commercial Editors: Lots *. (Note: MID / MIF is Mapinfo ).

* See GIS software for a good list.

May provide more detailed information if this does not point you in the right direction.

Quantum GIS, OpenJump, uDig, or GRASS should do what you want. However, you should be aware that all of these editors will most likely use OGR as a data abstraction library for this file format. Therefore, they have limitations of this OGR driver .

From the driver documentation:

MapInfo datasets in native (TAB) and interchange format (MIF / MID) are supported for reading and writing. Updating existing files is not currently supported.

This is probably what you are facing. Try QGIS again and keep that in mind.
