Richard,
The solution to your problem is relatively easy. One way of solving your
problem is to create Voronoy polygons around the positions of your rapid
transit stations. These polygons represent the area in which the point of
the rapid transit station is the closest. Next, execute the

You can use any of the following products from Mercator Geosystems:
The first is GridContour. This program creates contour lines and contour
polygons from any standard mapinfo grid file (*.mig).
The second is Triangulator. This program accepts any map containing
pointdata and can create:

You could also use your map of store locations to create a set of Voronoy
polygons. Each Voronoy polygon represents an area around a store location in
which that particular store is the closest available.
Once you have done this, you overlap this map with your customer locations

Michelle,
You can use Triangulator from Mercator Geosystems to
triangulate your elevation data. The resulting map contains triangle objects
with fieldson the average elevation, slope in degrees and aspect. The
slope information can be used for creating a thematic maps or other forms of

What you can do is take all the intersection points. Use these points to
create Vorony polygons. Vorony polygons (also called Thiesen polygons)
represent the area where the associated point is the closest. The next step
is to determine in which polygons your search points fall (standard

You probably want Voronoy polygons. With Triangulator from Mercator
Geosystems, you can easily create these.

Hi everybody
that comes with MapInfo 5.5 to
convert DEM's to *.mig files.
(4) has anyone written a .mig loader, say from a point file?
Yes we have see question 3 :)
Hope this helps,

Martin,
You need to create Voronoy pologons based on your first table. These
pologons represent an area around each datapoint in which this particular
datapoint is the closed point. After you have done this you can check in
which polygon the points from your other table fall. If you know this
Hi all,
Does anyone know which algorithm MapInfo uses for smoothing polylines?

If you want I could sign you up as a beta tester.
Just out of curiosity... how large are the datasets for
which you want to create Voronoy polygons?

One way of solving you problem is to assign each base class with a 'Magic'
number. You could use factors of 2. e.g. 1,2,4,8,16,32,...,1024,2048... etc.
The neat thing with these numbers is that if if you add them they act as a
logic OR. And from the result you van always deduce which were the

If I recall correctly, you must explicitly state that you want to convert
maps to GIFS during the MapExtreme setup. This is because the GIF format is
copyright protected and you are required to pay your dues. If you ommit this
the GIF format is not available.

Sarah,
You can look at the site of the US Geological survey.
http://edc.usgs.gov/doc/edchome/ndcdb/ndcdb.html . Here you can download
1:250,000 DEM files of most of the US (I am sure Texas will be there
somewhere :) ). You can use Mapinfo's DEM to Grid converter to convert the

You can download digital elevation models of most of the US at the US

I think its VRML and not VML.

A while ago there was a reference about standards for vector transfer
You could also use a different fomat to display your data. Why don't you
give the standard MapInfo grid (*.mig) type a try. It is available in MI

Stephan,
We have used the Grid sdk and converted it for use with Delphi. It is really
not that difficult.
We have developed several tools that either use MapInfo grids or produce
them.
