What is ArcGIS?

• ArcGIS 9.0 is an integrated family of GIS
  software products for building a complete GIS.
• It is based upon a common library of shared GIS
  software components, called ArcObjects.

What Geoprocessing?

• Geoprocessing is the processing of geographic
  information.
• Commonly used to describe a process when
  geographic objects are manipulated to create a
  new dataset.
• Many examples of geoprocessing

16
Common Examples

• Buffer
• Overlay analysis of vectors/rasters
• Interpolation
• Slope, Aspect from DEMs
• Map/Grid algebra
• Hydrologic analysis
• Classification

17
Not-so-Common Examples

• Geocoding
• Converting between file formats
• Projecting
• Select and export
• Zonal statistics
• Proximity analysis
• Editing

18
What is Geoprocessing?

• So, its just about everything! Well, not
  really
• Geoprocessing is not cartography, 2-D and 3-D
  symbolization, numerical statistics, querys,
  labeling and annotation, GDB schema, metadata

19
A few notes

• Geoprocessing is just beginning in the 3-D world
  and will likely increase.
• Temporal modeling
• Significant improvements in 9.x
• Incorporated into SA, ModelBuilder, 3-D
• Solar radiation model into Framework
• Process-oriented GIS (not by ESRI)

35
ArcToolbox
ArcToolbox is now a dockable window within ArcMap
and ArcCatalog.
36
ArcToolbox

• Geoprocessing tools are available through
  toolboxes or toolsets.
• Categorized by process type
• Create your own toolboxes and tools
• Full tool index and search functions
• Locate tool function
• Interface to ModelBuilder

37
Geoprocessing Wizard

• The ArcView 8.x Geoprocessing Wizard has been
  removed from the ArcMap interface.
• However, the functions are still available just
  located in separate toolsets.

38
Geoprocessing Wizard

• Dissolve Data Management gt Generalization gt
  Dissolve tool
• Merge Data Management gt General gt Append tool
• Clip Analysis gt Extract gt Clip tool
• Intersect Analysis gt Overlay gt Intersect tool
• Union Analysis gt Overlay gt Union tool

39
ArcMap Settings

• ArcMap
• Tools
• Options

42
Exercise 1

• Basics of Geoprocessing in ArcGIS Desktop

43
Exercise 1

• Start ArcMap.
• Open ArcToolbox. Find the tools that correspond
  to the 8.x Geoprocessing Wizard
• Create a new toolset, called GeoWizard Tools
  and copy the appropriate tools into it.

44
Exercise 1

• Lets answer this question
• What is the most common land-use/land-cover type
  for Delaware municipalities with populations over
  5000?

45
Exercise 1 - Data

• 2002 Delaware Land-use/Land-cover
• http//www.state.de.us/planning/info/lulcdata/2002
  _lulc.htm
• Delaware Municipal Boundaries
• http//www.state.de.us/planning/info/munbounds/mun
  bounds.htm
• Dont download these datasets! Both datasets are
  available on the classroom server in the share
  drive.

46
Exercise 1 - Process

• Start ArcMap
• Add the lulc and munbounds data
• Run the following processes using both ArcToolbox
  tools and the command line.
• Project
• Select
• Clip
• Summary Statistics

47
What is ModelBuilder?
48
What is ModelBuilder?

• The ModelBuilder Window provides a graphical
  environment in which you can build models.
• A model is a representation of reality. It can
  describe static physical and non-physical
  properties, work-flow processes, or both.

49
ModelBuilder

• ModelBuilder starts when you create or modify a
  model, done through ArcToolbox
• Models can be exported as graphics or scripts
  (models cannot loop, scripts can)
• Similar to ArcView 3.x and ERDAS IMAGINE
  ModelBuilder programs

50
ModelBuilder

• Data Elements
• Tool Elements
• Derived Data Elements
• Connectors
• Text labels

51
ModelBuilder

• Graphics keep track of running process
• Run running process
• Drop shadow process/data completed
• As data is created, it can be added to ArcMap as
  layers
• Right-click derived data, Add to Display

52
ModelBuilder

• Variables can be set on any process
• Models and scripts can be used as input to other
  models and scripts
• Models can be documented and shared
• Its not just about sharing data any more!

53
Exercise 2

• ModelBuilder

54
Exercise 2

• Start ArcMap.
• Open ArcToolbox and create a new toolbox called
  My Models
• Right-click the My Models toolbox and select New
  -gt Model

55
Exercise 2

• Objective Find a home within the study region
  for the rare trollopensis bibulosa (pickled
  strumpet)
• Habitat Criteria
• 2 degrees or less of slope
• 200 meters or further from primary roads AND 100
  meters or further from secondary roads
• forest cover 250 meters or closer to water OR
  wetland cover with elevation 5 meters or greater

56
Exercise 2

• Process Criteria
• You must be able to share your work with
  colleagues at other institutions
• Your work-flow should be designed to accept
  variations of habitat criteria
• Your work-flow should be easy to explain

57
Exercise 2

• No problem!
• We have ModelBuilder!

58
Exercise 2 - Data

• Feature classes
• Waterways
• Primary roads
• Secondary roads
• Landuse
• Rasters
• Elevation in feet (DEM)

59
Exercise 2 - Process

• Input sources in various projections
• Use DE State Plane NAD83 meters
• Variables to set
• Distance to roads and water
• Elevation minimum
• Slope maximum

60
Exercise 2 - Process

• Demonstration
