How to color topography by pixel value of tiff images

Hello, I’m trying to color the surface of mt topography by the pixel value or color value of tiff images formact because in these tiff image I have the value of the temperature of the region and I wanna show it in the topography view like this:

Hello, and welcome to the forums.

If you haven’t already, please stop by the Dynamo Primer as it’s a well-written entry into how to navigate and start using Dynamo.

Please keep in mind that this is a ‘do your work’ type of forum - everyone here contributes their free time to helping each other out, so the expectation if you need help is to provide some examples of what you have tried, what you think is/isn’t working, and what you’re looking to do.

To get you started off - you can take most image types and sample the pixels with standard nodes:

The next step would be to figure out what resolution/sample size you want for your region and how to incorporate that into your topography elements. That depends entirely on what you’re building your topography from and how precise you’re trying to be.

Hello, thanks for your answer. Here’s what I’ve already done:

I have a georeferenced topograhy (gray model upper) and I already know to get the pixel value (Vector Z) of the image (blue model under) but now I need to know how to georreference or translate and scale the image or each Vector Z, to put it on top of the topography and also how to color by the range of the value of the Vector Z. So I tried to make a Vector Analysis, but I dont know why the CoordinateSystem.Scale its not workint and I can’t see the geometry on Revit, only in Dynamo view

what do you want to produce- a topography object in Revit that has coloured faces ??

The outcome from the other post in this forum that you recently replied to ( Topography colouring - Packages - Dynamo (dynamobim.com))- was that a topo object basically has one colour- although a fudge was to use coloured model lines.

The only other option I can think of is to split the topo into subregions, and give each subregion a colour- but this is probably not desirable.

The topography tools in Revit are pretty poor (in my opinion)- so I’d suggest an application such as Civil3D, QGIS, Rhino, 3DS, even SketchUp could do this relatively easily
