Adjusting color of altitude in TINs

Question

Hello,

I'm trying to resolve one problem. I have many TIN files loaded into ArcMap. They overlap each other. The first TIN has altitude range between 134-190 meters, the second between 150-220 meters.
The first one has 9 color classifications (for altitude), between dark green to dark brown. The second also has the same classifications. Method for color classifications is set to equal ranges.

Could You tell me if there is a way to match theese color classifications to this altitude, so they can overlap and not look like in the photo?

Here is the photo of my problem:

PS. I'm sorry for my english, but I'm doing my best 🙂

Is it possible to set for all TINs ie. color blue 177 meters, yellow 180 meters, ect.

Yes, and no.

Yes, because when you pull a corresponding TIN sheet into arcmap, you can, from the symbology tab, press the Import button.
The window that pops up will give you an option for a pull down menu  where you can select what layer in the map that you would like to import  the symbology from.

I am not sure if importing symbology from another layer will recognize the minimum sampling size that you had set, so check to see if this needs to be adjusted or if it was actually carried over. This is important, because each TIN section will need to have its own sampling size, for instance if there are 13,876 records, set the sampling to anything larger than that, like 14,000 in order for the colour stretch to be applied over all elevation values.

I would also check to confirm if the exact break values you have specified are respected. So again, you will have to manually compare to see that your colour values are at the exact elevation range you had specified. If they are different, it is because the stretch is applied to the TIN in an 'overall' manner, based on the min and max values, not the discrete breaks.

For ease of use, and limiting duplicating symbology, would you consider creating a DEM from your TINS then to mosaic those DEMS together into a single raster that will contain your full range of values?

Anyone got any other suggestions on how to expedite this process? I am thinking with the new python mapping module that a script can be generated to automate this...Python gurus can join in anytime now, I am not there yet.

Ok, I understand. But I must do it manually for each TIN. Is there any way to do it once and import ie. one hundred or more TINs?

Look at this photo.

If this is for cartographic reasons, is that stretch a result of the sampling restriction or because of a different overall extent?

double click the layer in table of contents (by default, it is the pane on the left hand side), or right click -> properties

Look for the tab that says Symbology.

And you can adjust how it is displayed using Quanitities, on the left hand side.

You may need to increase the sampling size (how many records from your feature class that are actually included in the classification).
