RE: [MI-L] Points to Regions
Title: RE: [MI-L] Points to Regions Brendan, I see two ways of doing this in MapInfo without writting any MapBasic code. 1. Convex Hull will put a rubberband around your points and convert this rubberband into a region. The resulting region object(s) are based on the nodes from the input object. The Convex Hull operation can be thought of as an operator that places a rubber band around all of the points. It consists of a minimal set of points such that all other points lie on or inside the polygon. Since the polygon is convex, no interior angles are greater than 180 degrees. from the MapInfo User Guide 2. Voronoi will convert each point to an area that will cover the area closer to this point than any other point. The Voronoi polygon is a partition of space into cells. Voronoi takes points and produces regions (cells) as output where each cell contains exactly one point. Each cell is an area in which the contained points are closer to the enclosed site than to any others. Use Voronoi to generate these polygons from a designated set of points. It is useful for dividing areas of responsibilities for field offices or possibly postal zones. It ultimately gives you the areas that are closest to your point of interest. from the MapInfo User Guide If you use the second, you will afterwards have to combine the objects with the same common attribute into one region.

Does anybody know of a way to convert the foot print or a set of points make into a polygon / region. I have tried to query for one type and then buffer the objects (with the create single object option) but this creates a too course an object with excessive overlap because a circle shape is used. EG for 1 particular group of points 'x' the output should be From x x x /x-- x- x\ x / x\_ xx xxx Should become |xx xxx| x xxx x xxx \x xxx x xxx-/ x x x x \-x---x-x-x/ I am happy to write something in Mapbasic if I could figure out the algorithm (but a ready made tool would be better) Hope this makes sense - any and all help is appreciated.

RE: [MI-L] Auditing edits made to mapinfo tables.
Rich, I agree with you on this point. MapInfo hasn't been very good at giving feedback to the person entering the problem. I think this is simply because they didn't track that information. They didn't know who send in the bug or feature request. But I also think this is changing. They have implemented a new system for - at least feature requests - where the request is connected to a name and a email address. This should give them the possibility to contact the person who send in the request and even ask for more detail. I must admit that I still need to see that part work ;-) But they seem to be heading in the right direction. When you get a bug reported, you should get a bug number. This can be used to track the bug, not interactively on a web site, but fore instance via email. But you are right. It is a serious problem for MapInfo, if their costumers don't feel that they are heard. Especially as MapInfo keep saying that they want to listen to the costumers.

Many of the improvemnets that has been made during the last versions of MapInfo Pro have been made because users have asked for them. The best way to make MapInfo aware of you wish is to send the wish to your MapInfo contact person. This may be a MapInfo Partner or a person at MapInfo Corp. For MapInfo Pro wishes I would recommend either Moshe Binyamin for the US region and Tom Probert in the EMEA region. Peter, Thanks for your comments, your positive attitude, and your many help posts to the list. I have used MapInfo Pro since version 3.0 and consider it to be a very good product. Over the years I have run into various bugs and communicated them thru my MI Business Partner, and directly to Moshe B. on a couple occasions. Personally, I have been disapointed with the ressponse I received. I can remember only one occasion in which a bug was fixed mid-release (and this was a bug that I had reported in the previous release). Many projects use Bugzilla which allows users to track the progress of bug fixes, place feature requests, and receive notification upon resolution. It is a far more satisfying experience when a user fells that their input is tracked and respected, rather than having to plead with a reseller (Business Partner) who may or may not fully comprehend your problem, or get a direct dialog with a senior engineer. My point, which may have come off with an overly cynical tone, was that MapInfo has done little encourage my participation in the improvement of their product. Lest I start a flame war, I will leave it at that.

[MI-L] Combine adjacent regions with same attributes
Hi All I have a geology coverage with about 26,000 regions which I would like to simplify. There are about 6,000 instances of small slithers adjacent to larger regions with the same geology code that I would like to be able to combine. In other words if there are two regions with the same geology code that share a common boundary (i.e. more that 1 node) I would like to be able to combine them.

Re: [MI-L] Setting Universal Translator Input and Output Directoris
Hi Doug, If you are regularly translating lots of files, you might want to look at running UT in a non-interactive mode using a Windows script or batch file - you could write a script that when double clicked, automatically translates all the TAB files in a directory to SHP format and places them in another directory - I have pasted a simple batch script that I have written below as an example. MI have published a paper about this which should be available from their website. Batch file - paste the text below into a text file and give it a .bat extension. I have put a blank line between each line and the next to show where new lines should start as email often chops long lines up - they may need rebuilding. Copy the file into a directory with TAB files and double click in it in Explorer (or even create a shortcut to it elsewhere). All the TAB files should be translated into SHP files, placed in a subdirectory called SHP. Hope this is useful, Andrew rem Batch TAB 2 SHP conversion. Copy this file into a directory and run rem Shape files will be created in a subdirectory called SHP rem AH 26/11/04 if not exist .\shp mkdir .\shp for %%i in (*.tab) do ( C:\Program Files\MapInfo\Professional\UT\IMUT.EXE CFGenerate MAPINFO SHAPE ./ UT_trans.fme LOG_STANDARDOUT YES +ID %%~ni C:\Program Files\MapInfo\Professional\UT\IMUT.EXE UT_trans.fme --DestDataset ..\shp\ ) del /q UT_trans.fme pause Doug Wassmer wrote: List: I copied the entire UT subfolder which is located in C-Program Files- MapInfo-Professional by default and placed a copy of it in the target subfolder in “My Documents”. I didn’t know which files necessary and which were not needed, so I copied everything. I then created a desktop shortcut to the IMUTGUI.EXE in this subfolder. The universal translator appears to function normally if MapInfo is also open, but will not function properly if it is not. This was done to reduce the number of file navigation keystrokes in lieu of setting UT to always go to a default subfolder in “My Documents”.

My network is set up so that all “My Documents” directories actually reside on a server instead of the workstations so they may be automatically backed up daily using a tape drive. I don’t think that this will be an issue as this setup is seamless and some workstation operators are not even aware of it. We have a work process where frequent aerial pesticide spray applications are planned using MapInfo 7.0. The AgNav avionics units in our airplanes require an ESRI shape file (SHP polygon) input of a planned mission, and they provide a file “snail trail” (SHP polylines) of an airplane’s flight and spray activities. When a mission is set up, the mission planning SHP file is provided to the pilot via a thumb drive and the subsequent mission record SHP file is returned via a thumb drive. I have tried the MapInfo Options/Preferences settings, but I have not found a way for the UT to work in the “My Documents” folder by default. I someone could enlighten me, I would appreciate it.

[MI-L] disappearing raster images
HI We seem to be having an issue in v8 with disappearing raster images. The rasters have been registered in the same projection; the display within a zoom range feature has been turned off. Images will display some times but not all. At one point I could view the two images overlapping each other but when I go to zoom in they disappear. Even when zooming to entire layer you cannot see the image once it has disappeared. The only way to view again is to reopen in a new map window. It only seems to happen when you want to view two raster images at the same time both images I have been looking at were jpg 3Mb each so size should not be an issue. Has this happened to anyone else? Can you give suggestions as to how to fix?
