Heather McCann January 20, 2010 ModelBuilder for Beginners
Welcome! Has anyone here: • Used a GIS? • Attended an MIT GIS workshop? • Built a model (LabView, VB, others)?
Today you will: • Be introduced to ModelBuilder • Learn why you may want to use it • Create /edit a simple model using ModelBuilder • Connect multiple tasks together in one model • Add models to ArcToolboxfor future use • Export models in a way that makes them usable by others
What is ModelBuilder? A modeling program that allows you to build and connect geoprocessing tasks graphically. Can save the processes for future use or export to support your documentation (can save as a Python, VBscript or Jscript).
Why would you use ModelBuilder? • Automate repetitive tasks • Run complex analyses – even overnight! • Build repeatable/reusable workflows • Document processes performed on datasets (for publication or thesis work) • Create tools for future use as is, or build them into more complex processes • Visualize complicated workflows
Some starting points • Build models by building and connecting processes. • A process is a tool plus its variables. • The individual parts of a process are called elements. • The simplest model will include input data (variable), process that tells the tool what to do, and output data.
Without further ado… ModelBuilder
