Whats to say... well I'm a geek, I've always been a geek and I'll always be a geek.

I love writing software and tinkering with computer related stuff in general.

I run my own I.T consultancy company called "Digital Solutions Computer Software UK", I'm a Pluralsight author and the UK & Europe group manager for Lidnug (One of the largest .NET related user groups on the Linked-In network)

I'm a Microsoft Community Leader, presenter & lecturer of development related topics, oh and a Write a few computer books here and there for things like the Syncfusion Succinctly range.

I work across Linux, Unix, Windows and use lots of different languages in order to ply my trade, I've been working in I.T now for the best part of 30 years and will probably be here for at least another 30.

comment Why do I get these bands on my Height/Dem/Raster
It's worth a try :-) Iv'e also been mucking about with the GDAL .NET/C# bindings. I'm much more at home in managed code :) Will try your idea, and update as/when I have results.

Hmmm, exactly what I get too. Just extracted the premade, precut 50 meter tiles from the landform panorama and they line up perfectly, but because there all individual tiles, I'll need to convert and stitch them before there any use, may have to end up using these though, wanted to use gridded heights as I could set my own resolution.

PS: can you repeat what you did with yours, but tell me exactly what parameters you entered in your interpolation tool please?

YEa, found it myself just a moment ago, downloaded 'release-1600-x64-gdal-mapserver.zip' (Seems to be the only one I could find that had any mention of V2 dev. Page full of downloads, but no logical naming or help as to which ver is which. Anyway, downloaded, into a seperate folder, ran ogr2ogr from there and still no dice, the resulting merged shape, even with the newer version of Ogr2Ogr still creates a banded raster. Personally, given where I am now, I don't think it's the shape file merge. It's either the interpolation tool or the data.

How did you get your various versions? The GDAL/OGR2OGR that I'm using are the ones that came bundled with QGis. Also I'm using a 64 bit build, actually I just found all the versions, it'll be easier if I update my question.

As well as my previous update, Iv'e even gone through your process manually, doing each shape merge by hand, using exactly the same command line as yourself, but no joy.

Addendum to my update above : I do notice, particularly the band that is closest to where I live, does actually coincide with a grid square line, however , manual examination of the data shows no gaps.

comment Why do I get these bands on my Height/Dem/Raster
Awesome, I'll give that a try over the weekend. I did think of using GDal directly (I have numerous scrips from joining the OS Vector map district) [ Why do the OS make it so bloody difficult? :-( ] , anyway I was being lazy, and up until now I've not had a problem with the QGis joiner. I'll update once I know if this solves the issue.

yup, just go to the OS open data site, download the meridian 2 map, gridded height for the entire uk is in there in shapefiles along with other shapefiles for other assets. As per my description I just combined the NZ tiles. RE: your comment, again I checked, and there is (or appears to be) continuous coverage from previous tile to next tile with no gaps, where QGis has joined the shapes

Yea, that thought had crossed my mind too, so I went through the data manually (Painful I can tell you) and couldn't find any 0 values at all. :-(
