  1. GIS Data: Processing ArcToolbox, Geoprocessing and ModelBuilderSpring 2008 GISC 6382 Applied GIS UT-Dallas Ron Briggs

  2. ArcToolbox, Geoprocessing, ModelBuilder :Overview ArcToolbox provides access to geoprocessing • ArcToolbox is a dockable window in ArcCatalog or ArcMap • Comprises a set of Tools (750+) • Tools support all data types (coverages, shapefiles, gdb, raster) • Multi- step workflow available via Modelbuilder and/or scripting • Command line interface also available for traditionalists and/or power users GISC 6382 Applied GIS UT-Dallas Ron Briggs

  3. CAD GDB Database What is geoprocessing? • the modification and analysis of spatial (geographic) data. Projections Conversion Data management Spatial analysis GISC 6382 Applied GIS UT-Dallas Ron Briggs

  4. What is Geoprocessing used for? • Data processing/ data automation: Creation, Preparation, Conversion, Management • Data analysis/spatial modeling: Suitability, Sensitivity, Capacity, Risk GISC 6382 Applied GIS UT-Dallas Ron Briggs

  5. Accessing geoprocessing tools • Geoprocessing is carried out using tools stored in ArcToolbox • A dockable window available in ArcMap, ArcCatalog, ArcGlobe, or ArcScene • Tools run processes Opens ArcToolbox GISC 6382 Applied GIS UT-Dallas Ron Briggs

  6. Inside of ArcToolbox Toolbox • Toolbox: Containerfor toolsets and tools • Note: cannot have a toolbox within a toolbox • Toolset: Logicalcontainer of toolsand other toolsets(i.e. folder) • Tool: Singlegeoprocessingoperation (includesdialogs, models,and scripts) Toolset Tools GISC 6382 Applied GIS UT-Dallas Ron Briggs

  7. Coverage Geodatabase Shapefile Tables CAD Layer file Raster Behavior Geoprocessing Supported data types • The tools work with many data types GISC 6382 Applied GIS UT-Dallas Ron Briggs

  8. The tools work with many data types …Caution • Often there are different tools for different data types. Often there is one: • For shapefiles and geodatabse features classes • Another for coverages • Another for raster datasets • And they have the same name! • For example, there is a separate Clip tool for each of these input data types • Similarly, there is a separate Define tool for each of these input data types • Occasionally, there is a capability only available for coverages • e.g. conversion of SDTS (Spatial Data Transfer Format) or VPF (a vector format used by military) • Convert first to coverage, then convert coverage to shapefile GISC 6382 Applied GIS UT-Dallas Ron Briggs

  9. Tools with the same name • Some tools have the same name • Must distinguish between these tools in scripts • Be sure to get the correct tool for the data type you are processing Clips a coverage Clips a feature class Clips a raster GISC 6382 Applied GIS UT-Dallas Ron Briggs

  10. A special note on the Coverages Tools toolbox • Only available if you have ArcInfo Workstation installed • The toolset titles (Analysis, Conversion, Data Management) duplicate many of the toolboxes in ArcToolbox as a whole • You need to use these tools to process coverages • In some cases, there are capabilities here not available for other data types • e.g. conversion of SDTS (Spatial Data Transfer Format) or VPF (a vector format used by military) • Convert first to coverage, then convert coverage to shapefile GISC 6382 Applied GIS UT-Dallas Ron Briggs

  11. System (Esri provided) toolboxes • All tools are organized into toolboxes • System toolboxesare provided by ESRI. Number depends on • License level (ArcVIEW, ArcEditor, ArcInfo) • Extensions licensed • and you can create your own toolboxes (and tools) GISC 6382 Applied GIS UT-Dallas Ron Briggs

  12. Tool Counts—nearly 750 now (9.2) • Counts vary depending on license/extensions • ArcView: 102 tools • ArcEditor: 104 tools • ArcInfo: 251 tools • Spatial Analyst extension: 158 tools • 3D Analyst extension: 45 tools • Geostatistical Analyst extension: 1 tool • A total of 455 tools came with 9.0 • Feature class tools – 120 • Spatial Analyst tools – 185 • Geocoding tools – 5 • 3D Analyst tools– 20 • Linear Referencing–10 • Coverage tools – 57 Counts as of 9.0. 9.1 has an additional 171 tools 9.2 has additional 121 tools GISC 6382 Applied GIS UT-Dallas Ron Briggs

  13. The geoprocessing framework: four ways to run tools 2 Command line 1 3 Models Dialog 4 Scripts 4 ArcObjects GISC 6382 Applied GIS UT-Dallas Ron Briggs

  14. Selecting the way to run tools: Choosing between the four ways Selection depends on a user’s needs and abilities • As a dialog inside of any ArcGIS application • Simple, one at a time processing (GIS for dummies?) • Good for ad hoc processing • As a command from a command line • Very efficient for command line afficianados • Supports intelligent auto-completion of commands • As a process in a model (Modelbuilder) • An “executable flow chart” for GIS processing • Powerful multi-step processing, yet simple to create and use • As a function call in a script or program • Similar to AML in ArcInfo 7, but avoids learning proprietary language • provides decision making and looping to support batch processing In this course we will use #1 and #3 GISC 6382 Applied GIS UT-Dallas Ron Briggs

  15. Parameters • all tools have one or more parameters • pieces of information that the tool needs in order to run • some parameters are required, • such as the name of the input data set • some parameters are optional • most parameters have a default set, which • you should always review, and • change if it’s inappropriate for your application GISC 6382 Applied GIS UT-Dallas Ron Briggs

  16. Environment settings • “Customizable defaults” • Common parameters that are applied to all tools within a geoprocessing session • Settings work (“persist”) in all environments (dialogs, command line, models, scripts,) General settings Current workspace Output coordinate system Raster settings Cell size Mask Geodatabase settings XY Domain M and Z Domains Geodatabase raster Statistics Compression Coverage environment Comparison between prj files Precision for new coverages GISC 6382 Applied GIS UT-Dallas Ron Briggs

  17. Four levels of environment settings • User Profile • The settings will persist throughout all applications loaded by the user • Application Level • The settings will apply to all tools executed from that application • For a specific model or script • Settings apply to all tools within this specific model or script. • For an individual tool • Settings apply to a specific tool in a model or script Lower order (e.g. individual tool) settings override higher order (e.g. user profile) settings GISC 6382 Applied GIS UT-Dallas Ron Briggs

  18. Using Modelbuilder ArcGIS 9.2 has some major enhancements to Modelbuilder: Whats_New_in_Arctoolbox.pdf GISC 6382 Applied GIS UT-Dallas Ron Briggs

  19. Why Use Modelbuilder? • document the processing steps (workflow) that you carried out • You will forget • You may need to do it again • re-run the analysis to experiment with different parameters to see how results are affected • rerun the analysis if you find a mistake • carry out repetitive, multi-step tasks • provide other users (e.g. operations staff) with an exact workflow that they can replicate GISC 6382 Applied GIS UT-Dallas Ron Briggs

  20. The Elements of ModelBuilder • Model diagram window • Input variable • Tool • Derived data variable • Toolbar • Add Data or Tools • Layout • Zoom and Pan • Add connection • Run GISC 6382 Applied GIS UT-Dallas Ron Briggs

  21. Building a model: constructing • Create a new model • Drag tool into model • Drag data into model or onto a tool • Link data and tool GISC 6382 Applied GIS UT-Dallas Ron Briggs

  22. Building a model: running and documenting • Save and rename the model • Run model • Document the model GISC 6382 Applied GIS UT-Dallas Ron Briggs

  23. Setting model parameters Or double click on the tool’s process box to open its parameter dialog GISC 6382 Applied GIS UT-Dallas Ron Briggs

  24. Element States • Not ready to run (parameters not set) • Ready to run • Has been run (note the grey shadow) GISC 6382 Applied GIS UT-Dallas Ron Briggs

  25. An example,which we will now build GISC 6382 Applied GIS UT-Dallas Ron Briggs

  26. Alternatives to Modelbuilder:Options for Developing Additional Capabilities • Modelbuilder • Multi-step, sequential processing of ArcTools, using a visual development environment which comes as part of ArcGIS • Python, Jscript and VBScript • standardized and relatively simple scripting languages for repetitive processing, including loops and decision trees, using ArcTools • Python scripts can be generated from Modelbuilder • Visual Basic for Applications • Permits writing of VB macros for sophisticated customization and development within standard ArcGIS (ArcMap/ArcCatalog) interface (and thus requires license for these) • may incorporate ArcObjects, the COM compliant software objects out of which ArcGIS is constructed. • ArcGIS Engine • Set of embeddable GIS components (ArcObjects software objects) for use in building custom applications, independent of ArcGIS interface • Runs under Windows, Unix and Linux, with support for Java, C++, COM and .NET GISC 6382 Applied GIS UT-Dallas Ron Briggs

  33. Some additional detail… GISC 6382 Applied GIS UT-Dallas Ron Briggs

  34. Discontinued Products • ArcCAD • CAD product from ESRI • PC ArcInfo • 1st effort at PC based GIS • DOS based, command-line driven • Data not compatible with ArcInfo UNIX • Replaced by ArcInfo 8 and ArcView 3.2 • DAK (Data Automation Kit) • Subset of PC ArcInfo for data preparation for ArcView 3.2 • Atlas/GIS • once a leader in PC-based mapping • Bought by ESRI in 1996 & discontinued in 2001 GISC 6382 Applied GIS UT-Dallas Ron Briggs

  35. ArcGIS Version 8/9 With Version 8 & 9, now have two flavors: Desktop: • Largest Microsoft COM/ActiveX application to date • Full GUI interface • Customization via Visual Basic for Applications • New data base concepts: Geodatabase • Runs on XP/2000/NT only • no UNIX version available Workstation: • classic, command-line ArcInfo with AMLs (Arc Macro Language) for customization • same as version 7 and earlier, with minor enhancements • the only option for UNIX, but also available on MS XP • With release of ArcGIS 9, little reason to use unless under UNIX • Now, all capabilities have been moved to ArcGIS GISC 6382 Applied GIS UT-Dallas Ron Briggs

  36. ArcGIS Desktop Primary Characteristics • GUI-based tools • ArcCatalog, ArcMap, ArcToolbox • Geodatabase spatial data model supported in standard database environments • MS Access (.msb) for personal applications • File-based geodatabase with 9.2 • Any industry db via SDE for multi-user applications • Modeling of real world as intelligent objects • Houses, poles, not points, lines, polygons • COM/ActiveX components (ArcEngine) for embedding geography in other applications ArcInfo7: simple data complex applications ArcInfo8/9: intelligent data simpler applications GISC 6382 Applied GIS UT-Dallas Ron Briggs

  37. ArcGIS 9 Desktop Modules ArcCatalog (schema editor, with VISIO generation) • The base application for ArcInfo Desktop • Windows Explorer-like interface • for organizing access to data and metadata • For launching other Desktop apps: MAP and TOOLBOX ArcMap (object editor) • GUI for map creation and spatial data editing • ArcPlot/ArcEdit (from ArcInfo v. 7) & ArcView 3.2 View/Layout combined • Map projections on the fly (not via conversion as in AV) ArcToolbox (geoprocessor) • An interface to geoprocessing tools • In ArcGIS 8 it was a separate module • In ArcGIS Release 9 it’s an integrated window in ArcCatalog or ArcMap GISC 6382 Applied GIS UT-Dallas Ron Briggs

  38. ArcGIS Desktop Capability Tiers: Each tier has the same interfaces (ArcCatalog, ArcMap, and ArcToolbox), but an increasing set of capabilities are available within them (and $ price rises accordingly!) ArcView: • viewing, map production, spatial analysis, basic editing ArcEditor: • ArcView, plus topologic editing of geodatabases and editing of coverages ArcInfo: • ArcView and ArcEditor, plus more geoprocessing analysis, conversions, and full support for coverages. • Old, command line ArcInfo including AML support GISC 6382 Applied GIS UT-Dallas Ron Briggs

  39. ArcGIS 9.0 versus ArcGIS 8.3 • Main differences from 8.x are in ArcToolbox • ArcToolbox built into ArcCatalog and ArcMap rather than a separate module • All ArcToolbox tools support all data types (geodatabase, shapefiles, coverages) • 8.3 primarily support coverages • ModelBuilder diagrammatic modeling tool • Invaluable for tracking and replicating geoprocessing steps • New scripting capability for repetitive actions • Python, JScript and VBScript--simpler to use than VB for Applications, the only alternative in 8.x • Old aml (arc macro language from ArcInfo 7) also supported What ArcGIS 8 should have been when it was first released! Incorporates just about everything from ArcInfo 7/ArcView 3. GISC 6382 Applied GIS UT-Dallas Ron Briggs

  40. ArcGIS 9.1 & 9.2 versus ArcGIS 9.0 For Spring 2007 we will use ArcGIS 9.2 Ormsby text contains copy of 9.0 Gorr and Kurland contains copy of 9.1 Main differences in 9.1 from 9.0 • General performance improvement and user enhancements (e.g. pause drawing) • Additional geoprocessing tools (63 in ArcView, 86 in ArcEditor, 22 in ArcInfo) • Improved labeling of features on maps (Big change here was in 9.0) • Support for linear referencing • Network Analyst extension for transportation networks (shortest path, etc..) Main differences in 9.2 from 9.1 • Geodatabase and map documents (.mxd files) incompatible! • File based geodatabase • Faster, larger capacity (x 1,000) than MS Access-based personal geodatabase • Higher precision of coordinate storage • Identity/info. and measurement tools rewritten and greatly enhanced • Graphing re-written • Supports brushing (linking) between graph & map (as in Anselin’s GeoDA) software) • Supports cartographic representation • Can re-position features on map without changing coordinate values in geodatabase
