Hi- we have 40,000 addresses that we would like to automatically geocode. We have the
street address, which are not always accurate, as well as it zipcode, which we are
comfortable with. The problem is that sometimes the address is incomplete, e.g. 100
winchester rather than 100 n winchester.
Hi,
Does anyone know of a good drainage and pipe analysis program compatable
with MapInfo? Any help would be appreciated.
Thanks
Steve

SQL Select records from two tables where table1.obj intersects table2.obj
and you get a browser window. In my case, there were 77 records. I wanted
these in Excel, so I select all and copy-n-paste. But it only pasted 34
rows. I tried it in Lotus 1-2-3, same thing. Somehow the pointers are not
Title: Perto Rico Census Data
Hello,
I've gotten a lot of stuff for - ugh -
AkeView. There is census - down to block - , school districts,
.
One note if you get the school districts it has
some 460 fields and you will need to open the dbf in some database and drop the

My initial guess is that it is to do with the way that MapInfo does its
intersection calcs. Like most GIS packages mapInfo probably uses an objects
Minimum Bounded Rectangle (MBR) to initially determine if a object is likely
to touch another object.
The mathematical comparison on two
An alternative that I use to maintain the uniqueness of a column is to use a
generic function that looks something like this:
Function GetNextId(ByVal Tab_name as string,Col_name as string) as integer
dim cmd as string
Dim i as integer
cmd = "select max("+col_name+") from

Are there any duplicate records - ie do you get the same results when you
use a statement like
select * from table1 where object intersects any(select object from table2)

Alex,
If you have a road dataset that includes the zipcode as an attribute and you
have the zip code in the addresses perhaps you could do a series of
geocoding zipcode by zipcode eg
1) - get list of all zip codes (eg select zipcode from streettab group by
zipcode)
2) - select all roads with

you should just be able to rename the file back to *.mif. I've done this

What error message are you getting - or if none EXACTLY what are you doing?

Thanks Chris for the simple answer,
In Explorer, choose from the menu View Options
Make sure that the "Hide MS-DOS file extensions for file types that are
registered" is NOT ticked
Try renaming again.
Thanks Dawn for the initial idea.

Thanks to all who responded to my MI ID question. The solution of creating
an ID column and updating column with ROWID was perfect. Got that project
done in short order! I really appreciate the help.

David,
The easiest way to do this is to construct a command string and run that. eg
Dim exp as String
dim cmd as string
exp = "A, B, C"
cmd = "Select "+exp+ "from test"
run command cmd
Hope this helps

Thanks to all the listers who responded - it's good to know you belong! I've
had a look at all the replies, but it looks as if I was doing it right after
all, so the problem must lie in my tables. MapInfo Tech Support her in the
UK are looking at it as well, but the list is far, far quicker!
Bill,
I concur with the other answers to your question, sites are surveyed along
a flat plane, and areas calculated likewise.
With regards to 'getting more for your money' on a sloping site, it is far
more expensive to develop a sloping site as opposed to a flat one.
Unless you're building a dry
test.

Fellow listers,
This is my week for strange issues, I know! When I query a table and save a
copy of the query table to Microsoft Access, there is a column with the
MapInfo ID number. I have a list of student points that need to be
repositioned and querying by the MI ID number would be great.
