Beta of MI 5.5
Dear All, First of all I would like to thank you for your replies to my question about Errors Overlaying Objects... with MI 4.5.2. Some of you suggested to try MI 5.5 since version 4.5.2 includes some shortcomings in the algorithms of splitting layers. Is the beta version of MI 5.5 still available? We would like to check whether this version does not reveal the same problems. If so, we will not hesitate to cross update to MI 5.5 since we urgently need the splitted maps. Regards, T.

MI New Web Site
Hi all, I am in the process of producing a list of links and resources aimed at under-graduate students (or anyone new to GIS). All sites are of interest, but I would like to find more with an environmental angle (case study, academic sites, Gov organisations etc). Links to free stuff is also a great pleaser of students (software, data, expensive consumer electronics etc). If your own site would be of interest let me know on [EMAIL PROTECTED] Thanks Mark L Mark LightenL T GeographiqueWalesUK[EMAIL PROTECTED] http://www.ltgeographique.com
RE: MI Reducing number of nodes in polygons
Hello, I posted an utility on the MI List incomming FTP, that will perform this and other topological checks. Its ready to be picked in ftp://ftp.ctmap.com/mapinfo/incoming if needed. Sorry, but it's french, and I've no time now for a translation ... but there's an accompanying text. Have a nice day.

Is there a MapBasic program available that can reduce the number of nodes in complex polygons? I have several polygons that have up to 16,000 nodes, many of which are along straight lines that should not require nearly that many.

MI Check_Subject
Hi Todd McNeil, The problem in this code mainly lies in the line that has been coloured blue below.The problem persists because you are trying to insert the values of oObj, rArea and the rPerim but in the columns to which these value have to be assigned are not speciifed (Insert Into gsIntTable (Obj) ).When ever you have to insert valuse into a table by specific column wise then both the insert statement and the values clause in the statement should have the respective columns specified. This would be as follows in your statements case: Insert Into gsIntTable (Obj,(name of the area column), (the name of the perimeter column)) Values (oObj, rArea, rPerim) Thanks UJVALA KAKKAR Software Engineer Risk Management Software India Pvt.

TMCNEIL [EMAIL PROTECTED] on 07/01/99 09:16:00 PM To: [EMAIL PROTECTED] cc:(bcc: Tech Notes/RMSI) Subject: MI MapBasic I am trying to manipulate some code where the intersections of overlapping polygons are drawn as a table. Here's the code: Sub MakeReg Dim brushStyle As Brush Dim penStyle As Pen Dim oObj As Object Dim rArea As Integer Dim rPerimeter As Integer If TableInfo(TempHold,TAB_INFO_NROWS) 2 Then Note "At Least 2 Region Objects Must Have Been Selected."

I can make the table with the correct columns but I keep getting a message that says: "Number of columns in selection must be equal to the number of columns being inserted." Any ideas? I think I may be close.

AW: MI Table update column command
Tony, the way that I would go is a SQL query joined on the ID, with the properties table listed first in the From clause. This will return the property regions together with all required attribute data. Cheers, Andreas .

[EMAIL PROTECTED] -- Von: Tony Shepherd[SMTP:[EMAIL PROTECTED]] Gesendet: Donnerstag, 1. Juli 1999 01:14 An:MapInfo Email Group (E-mail) Betreff: MI Table update column command Using the "update column" command off the table menu can you add a temporary column that is a object from another table. For example I have a table of properties, with a region and a property ID. I have another table with names of people and a property ID. I want to copy all the objects from the property table to my names table only where there is a match between property ID's. I have written MapBasic code to do this but I am curious if it can be done straight from MI?

MI CLIP REGION?
Hello I am working with a map of the Ecozones of Canada, and a layer of provincial boundaries. The Ecozone layer extends beyond the land areas (i.e. into the Ocean, Hudson's Bay etc.). I have been trying to clip this layer by setting the clip region to a selection of the provincial layer. This works well, except that I can only do it for a single selection at a time. Is there a way around this? Can a make the provincial layer a single region? I just subscribed to the listsrv and I'm not sure if I'll get any responses right away. If anyone has any suggestions it would be great if the could email me directly at the address below (or Cc:).

MI Many thanks for the great help!
Great thanks to Jason Adam, Patrick Phillips, Simon Hume, Marc Pelosse, Martin Hodder, and all our list friends. My problem of moving objects in MapInfo was solved. Here I summarize the main three solutions: The most accurate way to accomplish that would be to first Export as a MID/MIF table. Open your MIF file in Notepad, and add the line: Transform 0,0,0,2000 'that's for %X, %Y, metresX, and metresY. Make sure your Projection clause line supports Meters for the MapUnits parameter (there will be a 7 in the first 2 or 3 digits). Now import the file back to MapInfo. One solution consists of exporting your tab file in DXF, and then import it and specify the parameters for the transformation. Look into the possibility of there being an Offset function of the feature.obj. This is easy to do with MapX and VB. Public Sub MoveFeature(Feat As MapXLib.Feature, FeatX_distance As Double, Y_distance As Double) Feat.Offset X_distance, Y_distance Feat.Update End Sub Thanks very much again for your great help.
