Contour lines to elevation for line data

mtorfi — Wed, 23 Aug 2023 18:56:05 GMT

Hello,

I would like to add elevation data to my line data. Currently, my line data does not have Z data. I saw online that I have to use feature to 3D. Is this the correct approach?

The data for elevation is a contour profile. The dataset for the contour lines can be accessed here:

https://geodata.dep.state.fl.us/datasets/FDEP::elevations-contours-and-depression/explore

I read on other websites that I should use topo to raster to make my contour profile into point data. Then add latitude and longitude to the point data and then use the point data as an input for my elevation in my line data.

I am unsure as to how to do the last part ("use the point data as an input for my elevation in my line data").

Also, is this the correct approach? I have provided some examples below.

Using the post below, I was able to find a solution to my problem.

https://support.esri.com/en-us/knowledge-base/how-to-determine-elevation-along-a-line-feature-at-a-sp-000022900

Couple things to mention:

1- transform contour lines into TIN (use create TIN tool)

2- transform TIN into raster (use TIN to raster tool)

3- make sure your 2D data has been transformed to 3D data (use feature to 3D tool)
