Hello All,

I have thousands of points scattered about 30+ polygons. I want to
create a thematic map that glows red in the dense point areas and
taper down to blue with little or no points. I used the Grid type that
allowed me to color the polygons based on point density. Rather, I
would like to have the color variations follow the point density.

Any ideas are appreciated, thanks!

Shane,

Long time no hear :) Basically you have two options.

1- Get a copy of vertical mapper or encom discover that allows you to do
some real neat grid analysis or
2- Use grid maker as part of the standard MapInfo tools set and create a
grid, update the grid cells with either the count of points or sum etc and
then do a theme by grid on the results.

Basically you are wanting to interpolate instead of having a distinct
boundary between the values. Use create thematic map and choose grid
instead of individual, range or other.

Good to hear from you.... You can always IM me through GRV if you want.

Mike

Hey Mike,
 
I figured out creating a grid with the tool Grid Maker and using the thematic map to count the number of points within each cell to generate a pretty cool map. I read up on Vertical Mapper since we last talked and it sounds awesome, now I have to build a need for it, LoL.
 
Thanks,
 
Shane
