  1. Advanced ArcMap For 796/496 Drs Badruddin and Herrington

  2. The Advanced ArcMAP User • What is an advanced GIS user? • Someone who knows what they are doing • Can quickly come up with a problem solution • W/out spending hrs in help • Knows the booby traps • Can make decent results documents

  3. So this course • Is about • practice, practice, practice • Familiarity with many of the tools etc. • Data management • GeoProcessing • Modelbuilder • Python • Results presentation

  4. Course foci V10 is different than V9.X • The main GUI is very different • But so are many of the specific ops, tools and their operation • Tables, for example • Data Management • And Help So the first step is learn the GUI! HERE IT IS 

  5. The Vehicle • The basic vehicle we will use is Geoprocessing. • what is that???? • Geoprocessing allows you to automate. GIS tasks to perform spatial analysis and modeling. What? • http://support.esri.com/en/knowledgebase/Gisdictionary/browse

  6. Dictionary • Geoprocessing: A GIS operation used to manipulate GIS data. • Geoprocessing operations take an input dataset, • perform an operation on that dataset, • Return the result as an output dataset • Geoprocessing allows for • definition, management, and analysis of information used to form decisions.

  7. Spatial Analysis • Spatial analysis is a set of techniques for analyzing spatial data.  The results of spatial analysis are dependent on the locations of the objects being analyzed.  • http://apps.carleton.edu/collab/spatial_analysis/SpatialAnalysis/

  8. Simulation • Simulation is the imitation of some real thing available, state of affairs, or process. (Wikipedia).

  9. GeoProcessing • So; GeoProcessing is the automation of workflows • Based on rich set of tools • and a mechanism to combine tools in a sequence of operations using models and Python scripts. • GeoProcessing can be Spatial Analysis, Modeling, or Simulation

  10. Models & Scripts • Put another way, Geoprocessing is the automation of workflows. • A Workflow is just a list of connected steps for solving a problem • And to be useful the steps have to be proven to work the way you want • Before you use them

  11. Workflow 1. objectives • Identify Problem • Identify measureable criteria • Define data needs • Time and Spatial properties • Extent • Accuracy

  12. Workflow 2: build the database • Get the data • Design and Build the database • Add spatial and attribute data • Manage/Edit the data • Test the procedures you plan to use!

  13. Workflow 3: Analysis • Define sequence of operations • Do the Analysis • Evaluate the results • Refine the Analysis • Rerun the sequence

  14. Workflow 4: Deliver • Create products • Maps • Tables • Graphics • Transportable workflow

  15. Script ( Python )

  16. Models Convert Convert Reclass Reclass

  17. Quiz

  18. QUIZ 1 • What is a Projection? • Which is correct: Long, Lat or Lat, Long, as order for geographic coordinates? • What does UTM NAD 27 ZONE 18 mean and where is it? • What does the term “Layer” mean?

  19. Quiz 2 • What are a Feature Class and a Feature Data Set and how are they different/ • How do you prevent a layer from being selected? • What is a data frame? • What does “Jenks” mean?

  20. Quiz 3 • What will Acres > 100 AND Acres <200 select from a parcel dataset? • What does the intersect tool do? • What is a raster layer • What does “Project on fly mean” • And how can it be a booby trap? • Does a Feature Class contain symbolization information?

  21. Class Structure

  22. The Class Structure • Tuesdays and Thursdays 4:00 pm to 6:30 pm in 310 Baker • Sit only in the first 3 rows. • NO FOOD or DRINK at any time! • Room will be open to you at 3 pm -- time for Help!

  23. The Schedule: wks 1-6 • Weeks 1-6 – basic topics • V10 interface(s) • Map composition • Table manipulation • Queries • Editing

  24. Schedule wks 6-13 • ModelBuilder • Raster Processing • Networks • 3-D Analyst • Python

  25. Individual Class structure • 4 - ~5 – Lecture / discussion / demo • ~5 to 6:30 Lab time for • Tutorials • Exercises • Tutorials are assigned but not graded • Exercises assigned and graded. • Tuesday’s assignments are short and are do at the start of class on Thursday. • Thursday’s are longer and are due at the start of Tuesday’s class

  26. Help • From inside ArcGIS • From the web directly • http://resources.arcgis.com/content/web-based-help • Help stuff • Blogs ESRI • Forums http://forums.arcgis.com/

  27. The assignments • Readings – chapters in book, on-line articles, ESRI help pages • Tutorials – From book, ESRI, or elsewhere – not graded • Exercises – Generated and graded by us. Will usually include a workflow, a schema of how you solved the problem, and, usually, a display of the results.

  28. Grading • Exercises – 30% • Final Project – 60% • Random quizzes – 10% Materials MUST be handed in on time or don’t bother (Unless you have a dammed good excuse!)
