MI Hazard Assessment
Hello, I work for a small regional inter-government organization in the Pacific called SOPAC (South Pacific Applied Geoscience Commission). I work in the "Hazards Assessment Unit" and we are working under the auspices of the "Pacific Cities Project" (which was tailored on the Australian Cities Project). We are in the process of trying to expand our GIS database so we can utilize it for rapid damage assessment; planning; hazard and disaster management; and more. The problem that we have though, is that we need to figure out a way that we can tie together the limited hazard information; census and building information in each of the Pacific cities we work in; and also identify data gaps. We are hoping to tailor a method that we could use in the region with this limited information. Our primary software is MapInfo with a few addons such as VM2 and Discover. We do a little work in MapBasic. I would be very grateful if anyone with any experience in these applications or any ideas regarding the integration of information or data layers (especially for the purpose of damage assessment), to please contact me. Should you need me to explain a little on the project we're working on please do email me too. Kind regards.

SUM MI VM2
Thanks to James Harvie, Ole Gregor and Eric Maranne I was able to get some sort of headway on this. I've cut and pasted most of the solutions from emails that were sent to me. 1. When using Grid Splicer to add building footprints to a DEM you have to be sure to use the correct splicing method. This will depend on which elevation value each building footprint is attributed with i.e. the height of the building above the ground or above sea level. Generally it is the building height above the ground and it sounds like from your problem that this is the case. In this situation you should use a Merge using the Maximum as the calculation method. The other method was to use the grid calculator and add the building heights grid and DEM. 2. This is not possible without the base option selected. I've seen it done using the 3D add-on for ArcInfo. 3. James' solution - For example if you wanted to show a street network file in 3D but you don't want to see the DEM you would do the following. First place the grid and the street network file in the same Map window. Next, open the Layer Control and make the grid invisible. Next, make a drape of the window. Finally, in GridView open the DEM and the corresponding drape file. Make the DEM totally transparent which makes it invisible. The drape files are still created with an opaque white DTM still viewed in the background. Eric suggested using vrml. See http:\\www.web3d.org for general info on the VRML standard, and Eric's site for VRML applied to geography examples ... www.cycweb.com/equipage http://www.cycweb.com/equipage Thank you again.

The layers include hazards, DTM, bathymetry, orthophotograph, etc. 1. I would like to update the existing grid (DTM) by adding building heights to it, so that they appear as extrusions on the DTM. Each building is represented by a region object. The information attached to each object includes the height of the building in storeys. The regions were converted to a grid with the Region to Grid utility, using the building height for elevation. Using the Grid Splicer utility, the building grid is stamped on the DTM. The projection and the grid units of the two grids are the same. The resulting grid has pockets where the buildings stand. 2. Can a building grid be represented as columns with a transparent base in Grid View? 3. Can a drape file be created with a transparent background? (Grid is not visible in the layer). Please do email if you would like me to clarify the above questions or if you know of a simpler software to use.

SUM: MI Missing *.ID
The solution offered was ensure the 4 basic MapInfo files (*.dat, *.tab, *.id, *.dat) were all located in the same folder when copying them. This included files of 0kb. It seems that one has to manually open the tables from each folder instead of opening from the *.tab listed under the File menu. This does not always work. -Original Message- From: Litea Biukoto [mailto:[EMAIL PROTECTED]] Sent: Wednesday, 12 April 2000 10:23 To: MapInfo-L (E-mail) Subject:MI Missing *.ID Hi When opening tables from different directories I usually get a message "File *.ID not found". The message pops up regardless of whether the files are on the same drive or on different drives. I operate on Windows NT, MapInfo 5.5. I did notice the same problem with the previous version of MapInfo but only with files located on different drives. I am down to getting the machine rebuilt however any other non-invasive solution shall be much appreciated. TIA.

MI Create points
I've tried to map a table of positions using Table\ Create Points but haven't had much success. The points appear as much as 2km out in both the northings and eastings! I tried creating the points using Discover but Discover keeps blowing. Has anyone else come across the same problem and found a solution? Please share it with me.
