Re: [Therion] 3D model height

The problem was that Therion used the Proj5 to transform the altitude even if it was above sea level, which did not need to be changed. This is now resolved. Balázs. On Tue, Feb 23, 2021 at 5:05 PM Balambér Hakapesz wrote: > A probléma abban volt, hogy a Therion a Proj5 segítségével akkor is >

Re: [Therion] 3D model height

A probléma abban volt, hogy a Therion a Proj5 segítségével akkor is transzformálta a magasságot ha az tenger szint feletti magasság volt, amit nem kell változtatni. Ez most megoldódott. Balázs. On Tue, Feb 23, 2021 at 2:54 PM Martin Sluka via Therion wrote: > I’m not sure about your problem,

Re: [Therion] 3D model height

I’m not sure about your problem, but as I find the most accurate heights are those from DMR5 models for Slovakia and Czechia. But there are differences between DMR3 and DMR5 as you may see on screenshot. Martin ___ Therion mailing list

No, the issue is the difference between the altitudes of the mean sea level (geoid) and the ellipsoidal coordinates. Balázs. On Mon, Feb 22, 2021 at 10:22 PM Benedikt Hallinger wrote: > As far as i understood, when you tag your data to be in a certain > coordinate system that should include

Re: [Therion] 3D model height

As far as i understood, when you tag your data to be in a certain coordinate system that should include all three data points when the coordinate system defines them. If you want an altitude offset, i would expect that we must manually convert. As an example: i tag my data to be wsg89, which

Yes, it is necessary, we are forced to cheat at the Hungarian EOV coordinates. Thanks. I'm looking forward to the Windows installer. Balázs. On Mon, Feb 22, 2021 at 9:19 PM Martin Budaj wrote: > Hi, > > Proj 4 and 5 uses a different conversion than Proj 6+ resulting in the > height difference.

Re: [Therion] 3D model height

Hi, Proj 4 and 5 uses a different conversion than Proj 6+ resulting in the height difference. Actually, the behaviour of Therion was inconsistent: when doing internal conversions it transformed only x and y coordinates, but when creating e.g. KML output it transformed all x, y and z coordinates.

If I were to enter the ellisoid height, the error of Proj4 would still remain on the EOV projection. I could work in a UTM coordinate system, but it would be much simpler if Therion didn’t recalculate anything. (There is no height issue between UTM and WGS84 because there is no conversion) This

Re: [Therion] 3D model height

Isn't EGM84 the reference ellipsoid currently used by WGS84? What you get with GPS is *not* sea level, but the altitude above that reference geoid (which takes into account gravital anonalys). If you calibrate your barometric altimeter to the hieght given by a height coordinate of WGS84 (like

Re: [Therion] 3D model height

Very rarely can anyone work at ellipsoidal heights. In local coordinate systems, it only makes sense for upper geodetic calculations. Only for GPS measurements we get an ellipsoidal altitude, even there the devices can immediately calculate the altitude of the EGM96 model with an altitude above

Re: [Therion] 3D model height

Hi there, if you measure the altitude with a barometric device, you do not get the altitude above the ellipsoid. You have to account for that at the input of your data. With the "cs" command you define your input data to be in a specific coordinate system, and also your altitude has to be

[Therion] 3D model height

Hi! When generating 3D models, Proj4 transforms between different coordinate systems. This also transforms the ellipsoidal altitude, but the data always refer to altitude above sea level and should not be changed. The finished models do not fit the topography, you have to cheat with the height to
