Fellow Maptituders, Happy new year! I have uploaded a new utility to the Directions Magazine website. It is free and open source (GPL v3). Leader Lines is an...
Very very nice. I'm currently using Leader Lines as well as your Layout Tools and was thus inspired to build a custom disclaimer/metadata toolbox specific to...
Hi Group: I just wanted to let you know that the 4th Quarter 2008 ZIP Codes have been released. Please see the following page for additional information,...
Could someone tell me how to do the following or if it is not possible: I have a layer with oddly shaped features. I would like to generate a new layer with...
Shaung, One way is to get the centroids of your irregular polygons (by exporting the centroids and then adding the new point layer). Then for each polygon find...
The GetMinimumSpanningCircle() command should get you what you need. It returns a circle "compound variable"-- you can extract the center coordinate and radius...
I haven't used GISDK in a long while - particularly since I installed 5.0. Now I need to rund some macros and I am not able to run the GISDK. I get the...
Mike, I'm not running Vista, and I have never seen this *specific* error, but it sounds like a permissions issue. Maptitude creates a file with an ".err"...
THanks. That sounds about right. Although I am not sure why I don't have rights in some of my directories. I did install Maptitude on my desktop computer...
Hi Everyone, I'm a new user of Maptitude and am wondering if someone can help me with a map. I have an EXCEL spreadsheet containing fields of OHU's (occupied ...
Jean, consider exporting the zipcode layer as a point file with data attached. You can then add the zipcode point file to you map as a separate layer and use...
... This should be relatively straight-forward, a matter of "Joining" your ZIP code data to Maptitude ZIP code layer, then doing a "Color Theme" on one field...
Yes - thank you Nick and Philip! I get confused sometimes between adding a new layer and just adding another theme... I think I now have the map I need - I...
I have a layer of shapes and a layer with points. How do I perform a spatial join that will tell me which shape a point is in? I know how to do a select by...
Hi Shaung, Assuming these are standard topological areas, such that each point can only be in one or no shapes, you should be able to just add a column to your...
Hello all, I was wondering if anyone knew of a way to draw a border around the outermost elements of a geographically contiguous selection set... Speficially,...
Hi Dan, You can create a boundary around features by using the Tools>Geographic Analysis>Merge by Value commands. 1/ Create a new field in the attribute table...
Sometimes Zip Codes cross county boundaries. I need to make a table of the zip codes that cross county boundaries that indicates the counties that Zip Code is...
Hi Dick, can you use a finer geographic resolution file such as census tracts? Add three new fields to the census tract attributes - "zip codes", "counties",...
Dick, I don't have an answer, but a question for you - how long have you been using Maptitude, and how did you get started with it? John If you always do what...
... Hi Dick, I can only think of a way to do it in DK code as follows: SetSelectInclusion('Intersecting') Loop thru the zip codes areas with a While loop, and...
Hi Dick. How about this? 1) Create Centroids for the zips 1.a Create field CountiyID and tag it with the Ids of counties 1b. Create a formula field ID *...
I have two replies that I am working through about how to detect Zips that cross county boundaries, I'll summarize the result. I am fiddling with it now....

Likely no one is interested in how I came to be with Maptitude except John, so hit the delete key. John, Since v 3, I think 1994. I took a course from Gerry...

Dick, Some of us are interested indeed! In fact, Gerard Ruston was my PhD advisor @ lowa and his specialty in location models introduced all his students to...
Since two people have told their "how I came to Maptitude" stories, I'll tell mine! I started doing "GIS" with the Calform/Symap/Symvu products from the...
I might be missing something, but it seems like there's an easy solution to the cross-county zip issue: 1) Use the County layer to split the zip code layer. 2)...
