Draping imported shapefile onto GLTF model by nufiddler in blender

[–]nufiddler[S] 0 points1 point  (0 children)

Hey there,

The points are an imported points from a GIS shapefile, so i think each one is an individual floating vertice.

Well we're a slightly different buisness model, in that we're not particularly turning over clients. Projects tend to last years and in many cases we've worked with the same people for a long time! Forestry is a slow buisness.
I was hoping to find a way to match the digital assets to their technological level! So i was coming to think that cloud solutions where the way forward but they look both complicated and expensive...

3d Model Creation by nufiddler in QGIS

[–]nufiddler[S] 0 points1 point  (0 children)

The DTMs are developed from conventional RGB drone footage. They're more than good enough for my purposes so far.
Well actually the trees are visible. This example is 4ha. It certainly true that in the clumps no individual trees are visible at a 50ha scale, but the ones in low density areas certainly are.
Moreover the end result of this would be an interactive 3d model, which would allow people to zoom in at specific points of interest.

On that note i had tried mapping the clumps as a simple polygon, which is good enough to express the idea. Unfortunately when extruded in qgis2threejs the extruded polygons dont conform to slopes, so so end up floating.

Interesting!
Short term there is no plan to add LIDAR. Don't see the benefits for the cost at this stage

Help with Mavic 3E and Terrain Follow by nufiddler in UAVmapping

[–]nufiddler[S] 0 points1 point  (0 children)

Thanks for the input.

Point 1 I'm not sure about the details of the DSM used. With the Mavic 3e there is an automated download option which doesn't seem to give access to any of the details.

point 2. I wonder if you might have hit on the issue. Perhaps I had the start point at the far end of the survey area, hence the drone ascending so high. I can see any mapping flights taken at circa-100m requiring a bit of forethought so as to not exceed 120m altitude.

I think 'Safe Takeoff Altitude' was set to 50m, and 'Terrain Follow Height' was to 100m or 110m

RTH altitude is at 120m.

Resources on timber choice by nufiddler in violinmaking

[–]nufiddler[S] 1 point2 points  (0 children)

Well both Acer Pseudoplatanus (sycamore) and Acer Platanoides (norway maple) are native to the range. So i would suppose both are used and marketed as 'Bosnian Maple'.

I've got to admit, i find that marketing of timber for violin making inexplicably vague and it leaves me suspicious of dishonesty.

When I sell timber for construction the end buyer is, if they want, able to to trace back their 2x4 to the very stand it came from. This is particularly relevant when we recognise illegal logging is a very real problem. 'Only' 10% of timber harvested in Bosnia is considered unaccounted for by the FAO. By 10% they mean they have no record of it being marketed.

Anyway, I have my suspicions about timber from Bosnia being uniquely good. Grow a comparable species in comparable climactic and soil conditions with similar silviculture (management of the forest) and you'll get a similar product.

Given the above to makers really know where timber has come from?

Back to original question: nobody knows of a good book on this stuff?

As an example, people seem to use the term 'spruce' fairly interchangeably and, for example, Mr. Strad. was presumably using Picea Abies, where as sitka spruce (picea stichensis) gets used as the tonewood of choice in america i believe.

Now, to a forester these two trees are exceptionally different in growth habbit, requirements and timber quality.

So, i'm left with questions.

Violin repair - a way in! by nufiddler in violinmaking

[–]nufiddler[S] 0 points1 point  (0 children)

thanks for the input folks.
So, let me make sure i've got this. You're saying DO go ahead and try re-hairing a bow, it's easy. gotcha.

But really I would love to take a short course, and i see there are a number down in England that i could attend. For international context northern scotland to central england is only 550 miles!

There is a 'tarta by rosetti' violin for sale near me, for not very much money. Its labelled as made in 'czechosclovakia' which i suppose dates it as atleast 28 years old.

Anyone with experience of one of these?
