A workflow used to generate raster layers from xyz data in ArcGIS

Open ArcCatalog##

1. create new personal geodatabase (e.g. foo.mdb)
2. file -> new -> personal geodatabase
3. add data

• right click on csv -> export to geodatabase (multiple)
• select csv files --> select output geodatabase --> ok

1. create featureclass (.shp files) from xy table

• open foo.mdb
• right click table
• input fields x = lon, y = lat, z = yield
• coordinate system of input coordinates select -> coordinate systems -> geographic .. -> world -> wgs_1984 -> open -> ok

1. import feature classes to geodatabase (multiple)

• select shp files created in prev. step -> add -> okay

Open ArcMap

1. Add data

• select foo.mdb -> CTL + select tables -> open

1. Export data to points to raster

• ArcToolbox -> Spatial Analyst Tools -> Interpolation -> IDW (with default settings)
• Z value = yield
• ok
