Re: [MI-L] RE: Conflation problems

Hi Ross, Are all higher order districts given as a sum of complete lower order districts ? Otherwise it may indeed be an ugly job to tackle, especially if you have a large dataset. The proper way seems to be to first get the lowest level in order, and then either re-digitize or

RE: [MI-L] RE: Conflation problems

I believe there's some for ARCGIS. I recall a book edited by Kovalerchuk (?Spatial data mining - something like that) which had a chapter on developing algorithms, but it's vague (my memory, and as I recall, the techniques). IL Thomas GeoSciSoft - Perth, Australia -Original Message-

[MI-L] [OT] LIDAR data

I realise this is not a GIS question (hence the OT marking). Has anyone here had any experience with LIDAR DEM data for soils / regolith / surficial geology? Interpretation, success stories, case histories, etc - that sort of thing. Any URLs to visit and look at? Or published papers?

[MI-L] 2 GB limit increased to 16 Terrabytes

Dear List I am pleased to report that By Design have defined and built a spatial file format that can be viewed from within MapInfo and can have files up to 16 Terrabytes in size. We have used the R-tree structure defined by Guttman in 1984 and implemented support for text, points, lines and

Re: [MI-L] 2 GB limit increased to 16 Terrabytes

Cheers Bob ! Bob, this sounds like the biggest improvement to MIPro in the last 4-5 years. Expect to be purchased by MapInfo Corp. right away ;-D I do have a two fast questions for you: 1. Does the mbx support multiple map window ? 2. Does the file format support password protection of

RE: [MI-L] 2 GB limit increased to 16 Terrabytes

I assume from this description that this is a format for vector data, with the same object types that MapInfo Professional (and bedmates) uses? And that those geometric objects are completely described by the GML standard? IL Thomas GeoSciSoft - Perth, Australia -Original Message-

Re: [MI-L] 2 GB limit increased to 16 Terrabytes

Hi Lars The first version of the MBX was released now because of a separate issue. The new Ordnance Survey data is in GML format whereas it used to be in a format called NTF. NTF will be withdrawn, so what I have also put in the MIMIC mbx is the ability to create Landline NTF files from our 64

[MI-L] Instruction on how to work with MapInfo using Geo Tracker (GPS)

Hi List, I have downloaded and setup my GPS through Geo tracker from Blue Marble Geographics. Does anyone have any idea of where I can find an instruction on how to work with MapInfo using Geo Tracker? Geo tracker help was not sufficient though. Basically I will be having a field trip and want

[MI-L] Duplicate Sub or Function MAIN

I've just relinked my project and now I'm getting the following link errors: - Duplicate Sub or Function MAIN found in ...\StopOpts.MBO. Error reading local variable names from GET_ZONES_SERVICES in ...\FacOpts.MBO. Duplicate Sub or Function MAIN found in ...\FacOpts.MBO. Error

[MI-L] ConvertCoord in MapXtreme

Hi List, In MapXtreme2004, is there a method for converting a point from map coordinates (lat/lon) to screen coords (in pixels), like the 'ConvertCoord' function in MapX? Cheers Tim All literature contained within this message and/or attached, is the opinion of myself and does not reflect

Re: [MI-L] 2 GB limit increased to 16 Terrabytes

I assume from this description that this is a format for vector data, with the same object types that MapInfo Professional (and bedmates) uses? That's correct. This new format holds the same object types as MapInfo and implements a similar RTREE spatial index - the main difference is the use

RE: [MI-L] ConvertCoord in MapXtreme

Tim, Have a look at the DisplayTransform class. That should do what you need map.DisplayTransform.ToDisplay(MapPoint, out DisplayPoint); Kind Regards Jerry O'Sullivan Jerry O'Sullivan GIS Consultant ESBI Computing Ltd Stephen Court | 18-21 St. Stephen's Green | Dublin 2 Tel +353 1 7038060 |

Re: [MI-L] Duplicate Sub or Function MAIN

Hi Terry, Any statement placed outside Sub/Function bodies generate an implicit Sub Main. Check for such statements, that's probably your gotcha. Best regards / Med venlig hilsen Lars Nielsen GisPro Terry McDonnell wrote: I've just relinked my project and now I'm getting the following

RE: [MI-L] Duplicate Sub or Function MAIN

Thanks Peter Lars Yes, I'd put some code to close the message window in the wrong place. I moved it to the end of the proc but accidentally put it outside the End Proc. Good catch. However: 1) wouldn't you think the compiler should notice this error, instead of waiting till link? 2) It

[MI-L] voronoi polgon

List, I have 2 point tables, stores and customers. I would like to find all the customers that are the closest distance to a particular store so I can assign information from the store to those customers. I created a voronoi polygon from the store points, then did a select statement where

RE: [MI-L] voronoi polgon

Bob, That sounds kind of strange. The voronoi for each store should represent the area closer to each store than to any other store - just as you expect. And therefore each customer should be within that voronoi that also contains the store they are closest to. Have you tried using the

RE: [MI-L] RE: Conflation problems

Hi Ross I am a MapInfo + Manifold user - I would have suggested using Manifold, because it has some very good inbuilt tools and features. Manifold's my GIS of Choice. But the book (published last year, I think - I just browsed it somewhere, and can't recall where) had the workflow / algorithms

RE: [MI-L] 2 GB limit increased to 16 Terrabytes

Bob Sounds good. Extensions to other flavours of GML would be nice. I wonder if I can encourage Manifold people to do the same? As you probably know, they bundle all objects into a single .MAP file, though external rasters and RDMS databases can be easily tied into that project file.
