it works fine...i just did it...you will get an error about launching MakeCont...that is an external proram...but, if you open the resource file and just comment out line 168 and recompile and run it is fine.  I opend the resulting file in text pad....give it another try..Dave

I think that GISDK is not backwared compatible back that far. I could not get it to work. Thanks for the suggestion anyway.

Richard,
The link below is to a macro written by a professor at Ohio State that generates the Queen's adjacency matrix...you will need to fool around with the output as  I don't think it outputs distance but the idea is simple...the Queen's spec is bacically the selection set of all touching...you can use SelectbyVicinity() to create sets from the origin area and then remove the origin areas (the main diagonal of the matrix), place the results in a multi-dimensional array...you can then use GetCentroid() and GetDistance()...I know this is quick and dirty but, it is the main idea.  Hope this helps.
Dave

Subject: [Maptitude] Q about marketing/adjacency tool
Bowling Alone is a great book about social capital, a very important concept for public health. This is a good read.
 
On another question (see .jpg attachments)
When I use the adjacency tool a 1st order band results in attachment 1 m2005001. This is a "queen" adjacency. Anything with an edge or a node.
But the feature that generates the dataview with the distances to centroidfs and IDs of adjacent polygons generates m2005002, in other words a "rook" adjacency table. Just polygons that share an edge.
 
Am I missing something ... is there a way to generate the "queen" adjacency table or does any one have GISDK code to generate a table of edges and nodes shared and if possible the centroid distances?
 
It would be useful to have a choice of rook or queen. Both are useful in different statistical modeling applications.

Hi Bob.
 
Social Capital is  a concept used mainly by sociologists and other researchers working on social equity, poverty, civil engagement and similar issues to refer to a social group´s potential to achieve mutual benefits through cooperative means
 
The following paper is cosnidered to be the one that pushed the concept up into the poltical and research agenda a few years ago:  http://xroads.virginia.edu/~HYPER/DETOC/assoc/bowling.html
 
In Europe it has been used for shaping political decissions on social welfare, health and housing for more a decade now, specially inthe UK.  I understand that the push is strong in the US too.
 
Non for profit organizations are using it as an indicator for focussing their efforts and evaluating their programs.
 
The concept includes a number of geographic dimensions, but, as far as I am aware of,  these dimensions have not been fully operationalized yet.  Mapping and quantification  of social capital are still in their infancy.  There is a field wide open for research on (and opportunities for) GIS applications here.
 
Cheers,
 
Armando

What is "Social capital?"
