Hi Tim, 

Can't answer all questions but one at least:
> Our old mapping system dynamically loaded the maps it needed to display
based on the filename. The filename contains the easting and northing of the
bottom left corner of the image.

> As far as I know mapinfo can't do this - you need three reference points
per image. Besides - I still need to register *all* of the maps.
If you know the coverage of a tile and it is rectified (say 1km) you
actually know all four corner coords. So now creating the Tab files should
be straight forward.

>Could I create one table with lots of raster images in it?

There is the Seamless Table Manager Tool (SEAMMGR.MBX) that allows you to
have one table that refers to multiple Rasters. I don't know enough about it
to advise you on it though.

Probably the on the fly creation and displaying implemented by you in your
app using MapX is going to be the most efficient implementation.

Subject: MI-L Registering *lots* of raster maps


Hi List,

I am new to mapinfo and I've just managed to register a raster image and
create a table for it.

I have got lots of raster 'tiles' that make up an entire map. Problem is, I
have over a million of them! Obviously I can't manually 'register' all of
these maps - I'd be doing it for the rest of my life! What's the best way to
do this? If I wrote a tool to automatically create the tables, can mapinfo
dynamically choose which tables to display? - because my geoset isn't going
to be very happy with 1,000,000 tables.

Could I create one table with lots of raster images in it?

Our old mapping system dynamically loaded the maps it needed to display
based on the filename. The filename contains the easting and northing of the
bottom left corner of the image.

As far as I know mapinfo can't do this - you need three reference points per
image. Besides - I still need to register *all* of the maps.

I can't 'stitch' them together. This is too time consuming as we have
several sets of a million tiles!

I'm thinking that I might need to dynamically create a table and load it
whenever the map moves or is zoomed. I'd use MapX to display the maps and I
can then do dynamic table manipulation.

Damn this is tricky.

Thanks for any help listers.

Kind regards

Tim Smith
