Jim-
Along the same lines as Jacques suggestion, you can create a rectangular
polygon around each point in just one command line statement...
update YourTable set obj = MBR(buffer(obj, 12, 10, "km"))
Make sure to use a copy of your point table as this replaces the dots with
boxes.  The 12 is the "smoothness" of the buffer, you shouldn't need to
change this. The 10 is the radius in kilometres.  You would change the
statement to read 1.5, "m".  Then you can thematically shade all those
polygons however you like.  Like Jacques said, you may want to select them
all and Object>Convert to region so that they behave properly when changing
the projection of the map window. 

FYI: The excellent 'Discover' add-on from Encom (www.encom.com.au) also has
that option when creating a "surface" from points like yours.

Regards,
Jason

Subject: MI-L Grid points to raster image?


Hi all,

As usual I'm in need of help!

I have a table of regularly spaced points. The spacing is usually 3m in the
X and Y direction. Each point has various attribute data and to display the
map of the attributes I am currently making a thermic map of the points and
sizing the points so that they meet but don't overlap to give the impression
of a raster image. Obviously this is not perfect as the redraw times are
slow and I have to use the display override to change the size of the
points.

It seems to me that I have basically a raster image there and MapInfo can
display raster images. Does anyone know how I could display this table of
points as though they were a raster table and preferably still colour them
using thermic mapping. Hopefully this way I would get faster redraw times
but still retain the ability to make multiple thermic maps of the different
attributes of each "pixel"

Anyone got any ideas?

                                        Jim
