Introduction to ModelBuilder: A Beginner's Guide to Geoprocessing in GIS

Join us for a beginner-friendly introduction to ModelBuilder, a powerful tool in GIS. Learn the basics of creating and editing models by connecting geoprocessing tasks graphically. We will discuss the advantages of using ModelBuilder, including automating repetitive tasks, running complex analyses, and documenting your processes for future use. By the end of the session, you will be able to build simple models, save them in ArcToolbox, and export them for others, enhancing your GIS project capabilities.

Presentation Transcript

  1. Heather McCann January 20, 2010 ModelBuilder for Beginners

  2. Welcome! Has anyone here: • Used a GIS? • Attended an MIT GIS workshop? • Built a model (LabView, VB, others)?

  3. 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

  4. 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).

  5. 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

  6. 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.

  7. Without further ado… ModelBuilder
