I have the following map:

enter image description here

The four layers have the following attribute tables:

  • SF_UrbanTreeCanopy_84

enter image description here

  • SF_Building_Footprints_84

enter image description here

  • GrassBeach

enter image description here

  • Water

enter image description here

I want to create a raster with the following extent:

Top: 37.822265 dd
Below: 37.708089 dd
Left: -122.522052 dd
Right: -122.351798 dd

That is the extent of the layer Water and with 0.00002 decimal degrees cell size. So the raster should have 5709 rows and 8513 columns. Now:

  • Values of the cells that are within SF_UrbanTreeCanopy_84 should be 1
  • Values of the cells that are within SF_Building_Footprints_84 should be 2
  • Values of the cells that are within GrassBeach should be 3
  • Values of the cells that are within Water should be 4
  • Values of other cells should be 5

That is I want to create a ground truth or a classification map.

Is there any way to do such in ArcGIS 10.3?

  • Do the 4 layers intersects ? – Shiko Feb 2 '17 at 5:26
  • @Shiko No, They don't – Sepideh Abadpour Feb 2 '17 at 5:32

ArcGIS has the feature to convert Polygon to Raster, and here is the link :

Here are the steps to follow:
(If it is a frequent process, better create a workflow using Model Builder):

1) Convert each file separately using feature mentioned above while setting the cell value as you pointed with other options such as cell size and max extent.
2) Use the Mosaic feature to combine all Raster layer into one (http://pro.arcgis.com/en/pro-app/tool-reference/data-management/mosaic-to-new-raster.htm)
3) Finally, to assign value to NoData which is 5 in your case, follow this link: http://support.esri.com/technical-article/000010059

You can use the feature to raster from conversion tool in ArcGIS and select the field value as Id values. Please go through the link for more details http://pro.arcgis.com/en/pro-app/tool-reference/conversion/polygon-to-raster.htm
