polygones (feature classes) in to one raster-data-set!

[PhilippWeisheit]

Hi there,

I hope someone can help me out here.

I created 5 feature classes every single class is a different typ of landuse and now I wanne have all classes in one raster data set.

I found already the tool - Polygon to Raster (Conversion) - but here I only can convert one class to a raster and not all classes.

What can I do?

Thx for your help

The easiest way would be to merge or append the polygon featureclasses into 1 featureclass and then rasterize. You can also rasterize each featureclass with the tool you mentioned, but the merging process in raster format is a little more tricky.

Xander sez, rightly:

If you do want to merge rasters, here are some suggestions

• Mosaic To New Raster (in my experience, this works best when you specify the output bit depth to match the range of your data).
• Use the Cell Statistics tool, with the DATA flag set so NoData is ignored.
• Implementing merge() in ArcPy map algebra‌
