2. Cartographic Representation Overview What is it? Why use it? Things to consider Getting started Working with it Types of Maps Projections Elements of a Map Map Design Considerations Map Symbols Principles of Color Text PlacementTypes of Maps Projections Elements of a Map Map Design Considerations Map Symbols Principles of Color Text Placement

3. What is Cartographic Representation? Method to symbolize features User-defined rules Doesn�t change the actual spatial geometry of the feature Feature symbols are stored within the geodatabase Stored as a property of a feature class Doesn�t replace layer files, maps documents, or style files Managed through a layer in ArcMap or in ArcCatalogManaged through a layer in ArcMap or in ArcCatalog

4. Why Use Cartographic Representation? Richer, more complex map symbology or visualization Better looking maps Store different types of symbols for different purposes Single interface to manage symbology instead of buried in the layer properties window

5. Why Use Cartographic Representation? Stored in geodatabase Better data management Dynamic symbols based on feature attributes

6. Example of Enhanced Symbology

7. Marker Editor Symbol editing Removes need for an external graphics program Edit feature independently of geometry

8. License Issues Can see cartographic representation in all license levels, including ArcReader Only licenses that CAN�T view are ArcPad and ArcIMS � high-performance server Need ArcGIS Desktop with at least ArcEditor to create

9. Technical Considerations Drawing performance is as good as symbology Works with any type of geodatabase Personal geodatabase File geodatabase Personal SDE Workgroup SDE Enterprise SDE Doesn�t work with Shapefiles (.shp)

10. Getting Started� Most efficient if you create some basic symbology for a layer in ArcMap This example shows a road layer symbolized by the type of surface

11. Example of RoadSurface Symbology

12. Creating Representation in ArcMap Right-click on layer that already has the symbology set - Select Convert Symbology to Representation Create a new name for representation Ex: Parks_Rep Can give a more relevant or descriptive name Creates two new fields in the feature class RuleID Override

13. Creating Representation in ArcMap

14. Creating Representation in ArcMap Custom names help identify representation

15. Creating Representation Properties of layer � Symbology tab Representations properties All symbols for a feature class are together

16. Symbology Stored in Feature Class

17. Symbology Stored in Feature Class

18. Symbology Stored in Feature Class Changes to the standard symbology is stored in the Override field as a �binary large object� - Blob

19. Editing Representation in ArcCatalog You can edit symbology in ArcCatalog � if data not open in ArcMap

20. Representation Management Mostly like assign and manage through the Layer Properties |Symbology tabin ArcMap Can�t have layer open in another ArcMap or ArcCatalog session

21. Rule Management Load Rule Provides pre-set symbology options Adds new Representation Rule

22. Rule Management After clicking Load Rule� you see pre-set options

23. Rule Management

24. Rule Management Double-click on rule name to change

25. Rule Management Creating a new feature, select representation rule to apply

26. Add New Rule Similar to Load Rule except it uses the default symbology (black)

27. Edit Symbology Add point, line, or polygon symbology Change the layer order of the symbology Remove a layer

28. Add Geometric Effect

29. Add Geometric Effect Add effect to all layers in a representation rule Or apply to single symbol May have to create a new symbol layer Creating a buffer around a point would require adding a fill symbol and applying the buffer geometric effect

30. Marker Placement Control marker placement Ex: random, clipped Requires a marker symbol

31. Marker Editor Full marker editing environment Create new or custom markers Import markers from a font Double-click on marker symbol Select Properties

32. Add New Marker Symbol

33. Marker Editor

34. Editing Representation Features Representation Toolbar Editing the geodatabase, so regular editing rules apply NOT editing the underlying geometry Desktop Help explains each tool

35. Representation Properties Window Must be in edit mode Feature selected Drawing tabshows currentsymbol layers

36. Representation Properties Window Tools tab show different properties for various representation tools selected

37. Override Field If you make significant editing changes to your representation rules, consider make a new or additional rules Any feature representation edits are stored in the Override Field Can change both the look and the geometric placement of the feature

38. Override Field

39. Desktop ArcGIS Help Search �Representation� Lots of topics& Explanations
