RE: MI Bug in Table > Update Column?

MI: rotated ellipses and moving nodes of polygons
I am trying to find solutions for two MI problems: 1) drawing ellipses under an angle (that is, how to create rotated elliptical buffers). Apparently, MI can only create horizontal or vertical ellipses. 2) an algorithm/code for moving nodes of adjacent polygons (that is, I want to change the shape of adjacent polygons by offsetting their common nodes). I will summarise responses that arrive to me directly Thanks a lot to everybody who tries to help Regards Zoran ** Commonwealth Bank of Australia (ACN 123 123 124) ** -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

RE: MI dispersion
Antoine This might not be the full solution your are looking for but it might be a work around. With VM use the "region to grid function" and set the "grid cell size" to correspond to a pre selected thematic range value (this is the logical part). Once the grid is created within the region you can convert the grid back to points. Obviously each required polygon will have to be selected, gridded and converted back to points. You will also have to do some testing to determine the required range values. I believe Vertical Mapper has a SDK kit.

MI Raster quality is poor
Hi all, I am using BMP, TIF and JPG files as aerial backdrops to my maps. When I print these however using mapinfo the photo gets blotchy in a regular way. Very much inferior to the bit map being printed in another package such as the paint, corel or other. Why is it so? And what can I do to improve this as it is not good enough to publish.

MI Layout Text and Frame Changes
I'm trying to create a little MapBASIC script in the MB window that will fetch
the next record of a mappable file, zoom to the coord of the currently selected
record and then modifies a layout so that the currently selected map window,
text labels (the window title is a text variable that contains the name of the
currently selected polygon)and browsers are updated. I'm having an awful time
with updating objects in a layout window. I can create a whole new layout
window and it will include the current data, but I can't seem to modify the
current one to update the contents. I don't want to spawn a hundred layouts if
I can help it.
I'm working with Create Text and Create Frame statements that follow a Layout
command. What I'd like to do is have the layout window active so that
subsequent create text and create frame functions operate on current (and only)
layout window, not create others.
I've tried operating on the current layout window by getting the window handle
of the layout window and specifying that as the "into Window" parameter of the
Create Text statement to change the text, but that doesn't work. Ditto the
Create Frame. Doesn't work: nothing appears at the right place in the layout
window. I've tried other stuff, too, but no dice. Here's the code from the MB
window I've been using.
Create Text
into window LayoutHandleID (variable for window handle)
layoutmaptitle (string variable)
(3.5,0.2764) (6.3972,0.5813)
Font ("Arial",0,24,0)
Anyone know how to make these changes to the titles and what not can be handled
through a script that doesn't have to create a new layout window to create new
text and frames?
PS: I've got MapBASIC but haven't installed it, but could if that's the
solution.
Thanks,
Tim

RE: MI Labelling with concentration
Hi David, I can think of three and a half solutions for you which I think you'll like with varying degrees of happiness. First is to perform a SQL selection that will result in the aggregate column Count. Be sure to group them by the postcode and add a column count. This will result in a browser with the count of responses/records per postcode and the postcode, but no map. You'll need to save this query as a new table and then geocode that new table. It can then be labeled with the count column as needed or shaded or whatever you'd like. From my experience, if you've had problems with printing a large number of overlapping points, this will also handle the situation. Option 2 is to thematically shade the boundary with the count of the objects within the boundary. This is a range thematic map. In it you'll create a range thematic of the boundary table you want shaded (for instance the postcode boundary). In the field section of the Create Thematic Map 2 of 2 window, select join as the field. This will result in the update column for join window. Select the table with your points as the get value from table section, joining where appropriate. Then in the calculate box, calculate the count. This will shade your postal codes with the count of the objects in each code with a range. Option 2b is to complete the thematic map in option 2 and then select to label the boundary with the temporary column that the data is shaded with. This temp column will be shown as a selection in the label with drop down box of the label options window after you make the thematic map. Option 4 will let you see the spread of the points. For this try the MBX tool Disperse points. This will take the points at a particular location and randomly spread them out around their original location. Make sure you make a copy of the original table first though as should you not like what you see, you can't undo the work without making the table un-mappable and then regeocoding it. It works very nicely though to show a broader spread within the boundary. I've tried to think of a way to label it with the number of objects at a location with your table as is, but can't seem to come up with a solution other than these 3.5. I hope that one of them suits your needs and good luck!

MI Volume in MapInfo?
Hi. I am a new MapInfo user. We are using MapInfo to portray information about airspace characteristics, (flights/week, time in sector, etc). It appears to me that MapInfo is limited to two-dimensional display even the terrain mappers are just presenting the surface of the objects... a folded two-dimensional surface...you cannot represent data that lives "inside" a mountain. It would be nice if we could represent all three dimensions of space, to show flight tracks with altitude, as well as lat/long. Can anyone offer any advice of pointers to software that would help with this?

You can GROUP BY columns not in the projection list. What you can't do now is this: when you have both a GROUP BY and an ORDER BY, you cannot ORDER BY things not in the projection list.

Re: MI MapInfo Fonts -- A Savage Journey into Pointless Pointsizes - REVISITED
Bill, I already took a look at it ! This is quite something ! Holy cow it requires a lot to control text renrering ! I am not sure that I can see from your program how I can read existing MapInfo Text objects and get the size of rotated text with your WIN API functions. How would you do it ? Read the MBR of the text object and then create a text object with WINAPI and check it's size ? I guess the approach to take is to try to "clone" the MapInfo text object with your WinAPI calls. Again I am not sure of the way to accomplish this. And then would that be working OK for most fonts, projections, etc. ? Thanks ! That goose is a tough one !

MI Refreshing Queries with ODBC tables
Hello Everyone, I have a client who asked a question about MapInfo and ODBC tables. He has a connected ODBC table that does queries with. His problem is that when he changes something in the table, the numbers/objects in the query do not refresh. The tables refresh but he wants the queries to refresh also. He said the only way he could get this to work is if he closed down the workspace and restarted it. He was wondering if there was a way to refresh the querieshe also told me Microsoft Access can do this so he figures MapInfo can do this. Is it possible to get an automatic refresh with the ODBC tables and the queries? (I hope I explained this good enough!) Any help would be appreciated!!!

Re: MI Radius Question
The answer depends on the form in which your data are assembled. I'll assume these are selections from the same table; the first, TWOMILE, is all the people within 2 miles of some location, and the second, FIVEMILE, is everyone within 5 miles of that location. In this case FIVEMILE also contains all those in TWOMILE. You will also need to have a unique identifying field in both, and let's call it something original, like 'Id'. Then the SQL select statement is: select * from FIVEMILE where Id not in (select Id from TWOMILE) into THREEMILE The result, THREEMILE, contains all those within 5 and beyond 2 miles of your site. The unique identifying field can be a number or a string; the only requirement is that no two records in your data have the same value for it. - Bill Thoen Erin OHara wrote: > > I have a radius of 2 miles and all the volunteers within that radius.

MI Labelling with concentration
Mappers, I have geocoded a number of responses to a survey by their postcodes (it would have been nice to use OS ADDRESSPOINT data but the addresses collected are too much of a mess to get any decent hit rate). As a result of this I now have in most cases one visible point on the map which actually represents between 5 and 25 respondents living under that postcode. Is it possible to label each point visible with an 'expression' that will show the concentration of respondents at each point. Sorry if this isn't very clear but its difficult to explain...

MI MapInfo Fonts -- A Savage Journey into Pointless Pointsizes - REVISITED
Hello all. I am (too !) trying to read the size of text objects in a MapInfo mapper window with difficulties. Following Bill Thoen's approach here's what I am doing: First I callObjectGeography () to retrieve the minimum boundingrectangle (MBR) of the text object. I then take the vertical distance between the min-Y and max-Y using the distance () function ininches, and divide by the map scale found in MapperInfo(FrontWindow(), MAPPER_INFO_SCALE) (after setting distance units toinches). I get some sort of approximate text size in inches which I then multiply by 72 to get points. Actually, this is not working two badly, since I am more looking for consistency over exact sizes. As expected, trouble begins when you try reading text with an Angle<>0.

RE: MI Radius Question
Hi Erin, You can make your 5 mile circle into a donut and use that ring to select the set of points you need. Make the table with the 5mi circle editable, then select that object and do Object>Set Target. Then select the 2 mile circle and do Object>Erase. Now you have the 2-5 mile donut you need and can do a point-in-poly tool selection. That operation is a permanent edit assuming you don't need the full 5mi circle anymore on its own. Alternatively you could select points within the 5mi and NOT within the 2mi via SQL.

MI Simple Query solved.
Thanks to Jose Luis, Russell, Keith, Ahmet and Jo for solving my simple problem. Simply 1. Make sure you have a column to store the information. You may need to add a column (using table maintenance) on the Coded Table to do this, make sure it has enough characters to hold the descriptions you're using. 2. Table > Update Column Table: Table you want to add the description to. Column: where you want the info. (This often defaults back to "temporary new column", so double check it) Get Value From: Table with the Description Join - Where coded table.column(comF7) = lookup table.column(comF7) Calculate: Value Of: Description(swimming pool) DOUBLE CHECK THE COLUMN... 3. Save the table. Thanks again Matt -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
RE: MI Routing Application Servers?
Dear John, You may be interested to know of a reference site using RouteXNetServer. Access www.madaboutbikes.com then go to "toolbox" to register your details, continue and click on "TravelMate" then "next". This is a UK based site so only UK routes apply.

RE: MI Nearest Neighbor Analysis
Hi Chiu If you're looking for Voronoi ... here some feedback: we compared TRIANGULATOR as suggested by Roeland van der Spek and VM as suggested by James Harvie on a dataset with over 200'000 points with the result that to my surprise TRIANGULATOR did the job perfectly and incredibly fast and VM 2.1 and 2.5 didn't do the job at all (cryptic error message) ... We went down to 50'000, tried, in VM, even to aggregate the points beforehand, with the same result ... I hope that VM 2.6 will have solved this and other problems, as it is basically a well designed and powerful product I really like ... *** REPLY SEPARATOR *** On 28.06.2000 at 15:18 James Harvie wrote: >Chiu, > >Vertical Mapper has a natural neighbour analysis tool which generates a >voronoi diagram (theissen polygons) from which density can be measured.
