Hi all, I have bathymetry file in ESRI GRID format. When I import into to VNS the low and high elevations are squashed. I have confirmed that all projection...
... Usually if you know what the range SHOULD be, and then determine what it IS, you can figure out what went wrong and how to fix it. It it's too short by a...
Thanks, yes I have actually already tried a mix of units. It should be meters according to my projection file but I tried feet as well just to see what the...
... Keep in mind the projection file usually only specifies the HORIZONTAL units that the projection coordinates are measured in. It makes no statement about...
Sometimes it's easier to correct the problem in VNS than try to figure out what's wrong with the original data. One of the Import Wizard pages allows you to...
True it does only specify the LINEAR unit and that is why I have tried both Survey Feet and Meter. I am at a loss as to how to cull the high and low elevations...
... Why? What format? VNS can normally read a 16-bit grid file from many formats. Try to avoid too much dinking with your data, for there creeps in the...
... What tool are you doing all this GIS work in? ... Um, what do you mean 1-bit? It seems like you're taking a lot of false paths that are distracting us and...
Because it failed to load, I would recieve "Please contact 3D Nature. This file can't be decoded properly at this time". I had created another 16-bit version...
ESRI 9.3, ArcCatalog to be specific. I had meant to type 16-bit. I agree about focusing on the source data and always attempt to do so. In this case it has not...
... Ok. I don't think you've said yet exactly what format we're talking about, and though you haven't yet answered it, I'm assuming you're using ArcGIS? I...
Yes to ArcGIS, yes I ArcGrid and the ARC ASCII file is what just crashed VNS. Perhaps ESRI changed some formatting with 9.3 service pack 1? As a quick aside, I...
... Possibly. Is it something you could ZIP and send to out FTP server (files.3dnature.com) for us to look at? Have you checked if anything else can read the...
So I was typeing this message out and the obvious occured to me. That is a hillshade file which I do not believe is the same as as standard GRID file, so far...
I have troubles width my beach ecosystems, my trees are getting flooded by the lake and I'm running out of ideas. I'm using 93 dynamic-linked vectors and...
... Emma, Based on your explanation, it would seem that your current beach materials will be distributed like so: No foliage from the beach edge to a water...
Hi all, I need to know the x,y,z coordinates from each pixel of a rendered image. I have found, that VNS can render to RLA-format, which stores Latitude and...
... Nothing that I'm aware of. Most 3D apps don't understand lat/lon/elev. What are you trying to accomplish and how/where will you be using these coordinates?...
I need the rendered image as a background still image for a web application, where gps-tracks from a database have to be layed over this image in realtime. To...
... You can save out the Lat and Lon buffers as RAW floating-point data in two different files. The values in these files are relative to the Project Reference...
You mean, that I have to save two seperate RAW-files for Lat and Lon ? I have also noticed, that VNS can export the elevation as RAW-files. Could I use this...
... Yes. There's probably a way where you could make it save them combined into one file, but the values would be interleaved within that file, and that would...
... Thanks for your answer. I changed the input low and high to -1m and -10m and the resultat got a lot better. I still have some few trees in the water but I...
Chris, we have a problem to interpret the RAW-file after opening in a Hexidecimal-Editor: 1. Each row of the RAW-file must be the LAT-value for one pixel in...
... left to right ? Assuming you saved the RAW file with Full Channel Precision, each pixel in the image will have a 4-byte IEEE-754 32-bit single-precision...
