Hello im a beginner of Arcgisand i have following problem
I have a shapefile where i need to some calculations. In the shapefile there are attributes (Area in m², Irradiance in W/m² and temperature in °C…) and I have to do a multiplication. I can do It manual by adding a new field and type in the expression : Power=Area*Irradiance.
But I need to do this for a lot of entrys and so I want to make a process in the model builder. How can I extract the data in the attribute table to do the calculations and add a field at the end of the attribute table with the calculated power?
thanks for your help in advance
