I have a line feature class of routes and a raster file with 12 unique values. I want to know how much cells of each value in the raster has that intersect with lines.

I've tried zonal statistics (as table) but the result is the opposite, I get the mean value of the raster file within each line. My needed output however is a table with in the first collumn the raster values 1 to 12 and in the second column the total area of that value that intersects with lines.

Is there any function that does this for lines in ArcGIS Pro?

  • rasterstats (Python package) will return an array where all pixels are masked except the intersecting ones; it is only a couple lines of code to create your table following that. As for an ArcGIS solution, I don't know. You might look at a profile tool, which should somehow fetch the values along the line. – Jon Nov 29 '18 at 14:39

Try the Tabulate Areas tool. Link to Tool Description here

  • It doesn't look like that will take a line feature as an input, unless I'm missing something. OP would need to rasterize the line first. – Jon Nov 29 '18 at 23:19
  • From the link: if a point or line is used as the input raster or feature class data, the area intersected by those features will be reported. – Jae Nov 29 '18 at 23:25
