RE: MI DXF convert to TAB Error
Hi Dina, when you import DXF into MI there is a Projection button on the dialog. Use it to set up the projection and also the map limits. If you have an object in the DXF that is out of those limits you get your error. To check the limits use zoom/extents in AutoCad ( you can have a small object someware and you don see it) Jure Ravnik.

MI SUM Updating tables
Thanks to Peter Strain and Robert Crossley for their suggested solutions
and to Karl Kliparchuk for his suggestion that I use Discover.
This was how I stated my problem :
I am trying to "get my head around" this problem. I have two tables of
down-hole data.
The first " Assay Results" is of the form (has these fields)
HoleID,From,To,sampleNo,Znppm
being respectively, the hole number, the from depth, the to depth, the
laboratory sample number and zinc concentration in ppm.
The second table "dhsusc" is of the form (has these fields)
HoleID, At, Magsus
being respectively the hole number, the depth at which the reading was
taken, and the magnetic susceptibility.
Typically Magsus has been measured at 10 cm intervals whereas the assays
are over intervals of about 1 to 2 metres.
I wish to determine averages, maxima and minima for Magsus within the Assay
intervals.
These are the relevant parts of the tab files upon which I attempted the
solutions
Assay_results.tab
HoleID Char (15) Index 1 ;
From Float ;
To Float ;
SampleNo Char (10) ;
Zn_ppm Float ;
SM_1020C-1MI_copy.tab
HoleID Char (6) Index 1 ;
Atdepth Float ;
__mV__ Float ;
Peter Strain's suggested solution translated to this, entered at the SQL
dialogue box but here presented copied from the Map basic window.
Select Assay_results.HoleID, Assay_results.From, Assay_results.To,
Assay_results.SampleNo, Assay_results.Zn_ppm, Min(SM_1020C_1MI_copy.
__mV__),Max(SM_1020C_1MI_copy.__mV__), Avg(SM_1020C_1MI_copy.__mV__)
from SM_1020C_1MI_copy, Assay_results
where SM_1020C_1MI_copy.HoleID=Assay_results.HoleID
And SM_1020C_1MI_copy.Atdepth Assay_results.From
And SM_1020C_1MI_copy.Atdepth Assay_results.To
group by
Assay_results.HoleID,Assay_results.From,Assay_results.To,Assay_results.SampleNo,Assay_results.Zn_ppm
into Selection
This apparently worked perfectly first time, I trust the averages maxima
and minima are correct (in other words have not worked them out some other
way). Rather than tempt fate, I chose, on Peter's advice to change the
name of the 'Atdepth' field from 'At' before starting. The field names
'From' and 'To' did not cause problems.
Robert Crossley's solution was tried by editing Peter Strain's solution to
Select Assay_results.HoleID, Assay_results.From, Assay_results.To,
Assay_results.SampleNo, Assay_results.Zn_ppm, Min(SM_1020C_1MI_copy.
__mV__),Max(SM_1020C_1MI_copy.__mV__), Avg(SM_1020C_1MI_copy.__mV__) from
Assay_results, SM_1020C_1MI_copy where
Assay_results.HoleID=SM_1020C_1MI_copy.HoleID And SM_1020C_1MI_copy.Atdepth
Between Assay_results.From And Assay_results.To group by
Assay_results.HoleID,Assay_results.SampleNo into Selection
Again, rather than tempt fate I took the liberty of altering Robert's
suggested 'Av(SM_1020_1MI_copy.__mV__)' to 'Avg(SM_1020_1MI_copy.__mV__)'
{Av may work, I do not know, sorry for the lack of faith}.
Robert's method as set out above also worked apparently first time.
Both solutions are imho largely similar, the grouping element of Robert's
is less complex and his Between function is less typing intensive than
Peter's.
My gratitude to all who replied
Regards Brendan O'Donovan Snr Geologist Tara Mines Ireland.

MI auto updating plots of points
Dear List, I am trying to create daily plots of positions of sea drifters using MapInfo. I have a text file which is appended each day with the new positions of the drifters and I am then plotting this. This means that each new plot shows the same information as the previous day but also with the new positions added. I am then plotting the points as an individual thematic map (thanks to everyone that recommended this) to show different symbols for the different drifters. This is all then saved as a workspace. What I would like to do is to update the textfile in the workspace each day and get the map to update automatically. I thought it would do this but it gets confused and mixes up the symbols. Is there a way to avoid having to recreate the same map each day ?

RE: MI Thanks for the QueryN suggestions
Hi Mick,
If the query is based on a SQL statement, the query can be saved in
the workspace. On the other hand, if the query is based on the user's
selection of elements, there is no way for the workspace to keep track of
the selection. So it can't be saved even if you give it a name.
If you want to actually save your manual selection, you have to find out
what condition will pinpoint the ones that interest you. Usually, you will
use the unique ID of the object and list them in the SQL statement:
Select * from your_table where ID in("001","323", "5435", "65313") into
My_selection
This way, the selection will be saved in the workspace. I'm aware that it
can be tedious to list more than ten items... in this case, you can use a
geographic component in your query, like a round buffer.
The secret is to be able to put words to your selection.
Good luck

Using only MapInfo or with other tools like Vertical Mapper or other, there is some similar function to the button of information that instead of showing information on the pressed object (like name ,address,etc.), show me a picture of the object or better it executes me a video containing information on the object pressed for example, if it is a hotel, a small video of the hotel, their rooms, as well as their diverse attributes , etc. ; this is for a map of advertising type.

RE: MI Creating a template layout
Hi Vinesh, This is straight forward. Simply create your layout as you want it including the map frame and then save it as a separate workspace. To get the date working open the workspace file in a text editor and find the string that you entered when you created it and replace it with the command Curdate() eg "Printed on "+CurDate() You may want to use the formatdate$() function to return the date as a formatted string eg "Printed on "+formatdate$(CurDate()). Save the workspace file and then when you have a map ready that you want to use with the 'template' just open the workspace file and set the mapframe to point to the appropriate map. BTW to assist in creating maps I have written little utility that enables the user to select a map frame in a layout and enter the scale. The program resizes the map window to the same proportions as the frame. It really speeds up the map production process as you don't need to worry about setting the map window size before drawing the frame in the layout. I can send you (or any other readers) a copy of this if it would be of assistance.

Sector1 155. 12. Sector1 155. 7.3167 Sector1 154. 7. Sector1 149. 7. etc Sector2 141. 5. Sector2 141. 9.6167 Sector2 144.2500 9.5000 etc Problem 1 -- My first effort simply used the MapBasic 5.5 statements dim objSector as object Create Region into variable objSector 0 Alter Region objSector Node Add (fltX1, fltY1) Alter Region objSector Node Add (fltX2, fltY2) etc This code created the regions ok but had a problem. The centroid point of each region was located at the first node of its boundary polygon, making autolabelling ineffective, and -worse- making manual repositioning of the centroids with the MapInfo Pro node editing tool difficult. Problem 2 MapBasic 5.5 contains the statement Alter Object objSector Geography OBJ+AF8-GEO+AF8-CENTROID, objPoint although it does not appear to be documented in the on-line Help. My second attempt was to compute the MBR of each sector (xmin,ymin,xmax,ymax) and then try to retrospectively set the centroid property using the statements dim objPoint as object create point into variable objPoint((xmin+-xmax)/2,(ymin+-ymax)/2) OnError goto err1 Alter Object objRegion Geography OBJ+AF8-GEO+AF8-CENTROID, objPoint err1: The intent of this code was to set the centroid to mid-point of the region's MBR if that point lies within, or on the border of the region, otherwise (if the region has a concavity or hole in it) leave the centroid at its default position on node 1. Unfortunately the implementation of Alter Object Geography OBJ+AF8-GEO+AF8-CENTROID seems to be faulty in that it bypasses MapBasic's error trapping mechanism, so that, despite the OnError statement, the program simply aborted whenever it encountered a problem region. Problem 3 -- I could find no standard Mapbasic predicate function PointInPolygon that could be used to detect the situation that causes Alter Object Geography OBJ+AF8-GEO+AF8-CENTROID to crash and therefore avoid it. Certainly one could use the SQL +ACI-within+ACI- operator to make this test, but the code would be clumsy and inefficient, as you'd have to create and populate two temporary MapInfo tables, with all the file I/O overhead involved, in order to implement the test.

MI Custom Symbols
Just a short note to thank everyone who replied(and there were alot of you). It seems that the popular choice was to create your own true font type which works great. However to the people who want to know how to create there own symbols, the most simple way is to use the Symbol tool in The tool manager Utility(did not know it existed). The symbol tool allows you to create your own symbols and automatically updates the MapInfo Compatible symbols list. anyway thanks heaps Richard -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
MI mbx utility
looking for an mbx utility that allows you to search by address from mapinfo pro into Mapmarker Plus geocode engine, and then display the location in Mapinfo Pro. I want to be able to take advantage of the address level data in Mapmarker without buying the EAL street pro. I seem to remember someone in the past had already done this. Info appreciated.

RE: MI requête sql...M.Paris
Daniel, the easiest way is to save a copy of the first table, append each of the other three tables using Table Append Rows to Table so that you end us with a single table covering all of your 4 existing tbles. Then 1. edit your new table, 2. select all 3. set target on, 4. draw the zone extent as a rectangle or region 5. select the zone object and 6. Choose objects erase outside This will get rid of all data outside that zone. excuse me if my limited understanding of french meant that I completely missed the mark.

MI QueryN suggestions
It is always very dangerous to work with the cosmetic layer because it is
only defined as an unbounded long-lat and copying objects to it may cause
changes in the nodes coordinates.
There is a much simpler way to do it, just "save as" of selection with a
given name. If you look the trace of that operation in the mapbasic window,
it will look like
Commit Table Query5 As "D:\OD98\Carto\selo.TAB" TYPE NATIVE Charset
"WindowsLatin1"
The selection done by hand has been translated in QueryN (N will depend on
the number of previous queries).

Hi Guys...Sure you can save a manually selected set of items. Clear the
cosmetics layer, make your manual selection, copy the selection, paste into
cosmetics layer, then save it. A bit round about but it works; let me know
if your particular job won't allow that

Subject: RE: MI Thanks for the QueryN suggestions
Hi Mick,
If the query is based on a SQL statement, the query can be saved in
the workspace. On the other hand, if the query is based on the user's
selection of elements, there is no way for the workspace to keep track of
the selection. So it can't be saved even if you give it a name.
If you want to actually save your manual selection, you have to find out
what condition will pinpoint the ones that interest you. Usually, you will
use the unique ID of the object and list them in the SQL statement:
Select * from your_table where ID in("001","323", "5435", "65313") into
My_selection
This way, the selection will be saved in the workspace. I'm aware that it
can be tedious to list more than ten items... in this case, you can use a
geographic component in your query, like a round buffer.
The secret is to be able to put words to your selection.
Good luck

I'm a little confused, why can't you save a named query selection in a
workspace?

Hello List,
Thanks for all your input. I was hoping to find a way to save a selection
with a specific name within a MapInfo Workspace. It seems the only way to
rename a selection is through the Query menu and select all into a new
table
name. Because QueryN does not get saved in the Workspace, the new table
name does not either.
Thanks,
Kirk

RE: MI MapBasic PointInPolygon predicate function
the simplest answer to your problem is to convert the regions to polylines, and then back to regions - two lines of code and Mapinfo puts the centroid in the middle where it should be for you.

MI Copying Boundary Lines.
I have a mapinfo table of which contains very detailed regions. When I say detailed I mean the bounday lines are made up of hundreds of points over a short distance. What is the best way of copying a piece of this regions boundary so that when I digitise another region adjacent to it, they have identical boundaries? Any help would be much appreciated.

MI 3D and 3D glasses in MapInfo-Vertical Mapper-Virtual Frontier
Well I've finally seen something unexpectedly awesome from MapInfo, Vertical Mapper and Virtual Frontier. I was talking to Steve Bauch at Northwood Geoscience, he's the Virtual Frontier rep there that I have been dealing with at work. I work for the Department of Fisheries and Oceans in Halifax Nova Scotia. Our particular office uses MapInfo / Vertical Mapper and at my urgings has recently purchased Virtual Frontier. Using 3DLabs Oxygen VX1 32 MB video card and our PIII 600 NT machine we can now use 3D panchromatic glasses to view Vertical Mapper and Virtual Frontier visualizations on screen in jump off the screen 3D! Vertical Mapper grids in MapInfo map windows, 3D Viewer and Virtual Frontiers flight window are really 3D! Not sure if anyone out there new it though. I talked to Steve and he didn't know that Virtual Frontier did it, nor Vertical Mapper. It seems that the 3D effect is entirely the result of how the graphics card displays the info on the monitor. I'm not sure what other graphics cards can do it but 3DLabs Oxygen VX1 card can. It is so incredible watching the terrain fly by in Virtual Frontier in true 3D!!
