Re: MI Enter a Whole New Dimension! V6 3D Map View
I would like to pipe in. I took a DEM from NY's GIS Clearinghouse and converted to grid (DEM to GRID tool)and overlaid a road centerline file and then viewed in 3D and it looks great. These new DEM's are much better than the older ones. So, there might be an issue with "garbage in garbage out" phrase. Personally I am using this tool more than I would have thought. We would have never bought Vertical Mapper (didn't see the need). Now if we could only find some data with 2ft contours (highest point in Huntington is 392ft) I might just want to pick up a copy of VM. ,,, /'^'\ ( o o ) ---oOOO--(_)--OOOo-- Michael Naughton Town of Huntington Highway Office 30 Rofay Drive Huntington, NY 11743-5728 V 631-351-3076 F 631-499-3512 www.tohhighway.com [EMAIL PROTECTED] Longitude: -73.20 Latitude: 40.50 .oooO ( ) Oooo. -\ (( )--- \_)) / (_/ -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

First, Eric's comments are spot on, especially "geographic 3D is an art". Second, you can definitely "try Vertical Mapper" from Northwood as Kirsten suggests. They also have a new product called Virtual Frontier. Finally, about the image in our glossy brochure and how I created them: I think the biggest factor is that I imported DEM directly into a grid instead of interpolating a grid from point data. Our inverse distance weighting interpolator is not well suited for terrain data. After that, the street data drapped over it without a hitch. >The draping of the vectors over the grid was so bad it wasn't worth >proceeding. What exactly is wrong with the results? -- 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 Enter a Whole New Dimension! V6 3D Map View
Hi Ian, You could always try Vertical Mapper for MapInfo. Some of the product features include: Interpolate values between points Colour and display grids Intervisibility and viewshed tools Contour creation from points Natural neighbourhood regions and density surfaces Trade area (huff) modeller Statistical data aggregation 3D Views Kriging Access www.mapcentric.co.uk/VMfactsn.htm for more information. Hope this helps.

RE: MI Enter a Whole New Dimension! V6 3D Map View
MI uses a matrix mesh to render the geometry ... and not a Triangulated Irregular Network (a Delaunay triangulation). When using such a matrix, you just can't expect to get sharp edges (near vertical facets), so, if you're reservoir is near a hillside, it'll spill over it... same applies with hillside roads : they'll present an inclination, following the underlying geometric model. One turnaround is to use a very fine grid (so the matrix cells are very smal), but your model goes huge ... Another problem concerns MI lack of raster twisting ... if your aerial shot isn't orthorectified, with lens effects compensed and hidden faces compensated ... just don't expect from MI to do it ... and you may find crests on hillsides and water running up a mountain ... IMHO, it's better to use MI 3D capabilities within the main use of MI : doing and displaying analysises. You won't have these problems if you're draping the content of a thematic map ... if you're seeking realism, you'll need other tools (VM for a start (but only a start ...)) (as I said in previous mail, sneak peek : www.geovrml.com) Have a nice day.

RE: MI Enter a Whole New Dimension! V6 3D Map View
... :-) geographic 3D is an art ... I've been using MI, VM, a whole bunch of home grown tools to produce my 3D models, as well as a lot of time consuming trial and error ... and a few years later I can tell you : To produce a good 3D model, a good tool is necessary, that's sure (and MI alone isn't what I would call a good tool for this), but it needs too an understanding of all the underlying processes (from the tools limitations to the graphic hardware capacities, going thru the generating and rendering processes). MI push button generation is easy, but doesn't allow for going this far and deep... unless you're mastering the tools from the guts (ie, you're part of MI developpers crew...). If you're interested in (imho !?!) good geo3D models go to my pages www.geovrml.com for a sneak peek ... the site is still under construct, so just take it as a preview ... I'll communicate a bit more on it as soon as it'll be finished, for I'm introducing new paradigms for 3D terrain exploration and simulation tools (like 3D intervisibility that can't be displayed in 2D ...), and i'll like some feedback from the list, but I'll wait for ringing the bells (i'm off for vacations right now ... :-))) Have a nice (working?) day ;-) Eric. -Message d'origine- De: Brown, Christopher (HI Cartographer) [SMTP:[EMAIL PROTECTED]] Date: jeudi 10 aout 2000 05:50 A: [EMAIL PROTECTED] Objet: MI Enter a Whole New Dimension!

Has anyone tried to do the same? I gridded a table of contours (1m Interval) & spot heights digitised from 1:10,000 aerial photography. I chose the smallest cell size MI would let me. Otherwise the rest of the settings were default. Upon creation of the mig file I placed the vector contours and roads over the grid and created a 3D view. The draping of the vectors over the grid was so bad it wasn't worth proceeding. I tried overlaying a 1m resolution raster over the grid and the same? Go to 3D view properties and increase the resolution, still the same? I am going to see if there is any tutorial sample data on the MI6 CD now and see if I can produce something at least half as good as what is shown on the brochure!! Any feedback welcome.
