10. Limitations & Challenges Considerations

11. Many people are used to the old standards. Surface Types are sometimes divided between two symbols in the current MicroStation Maps. Different standards are needed for the different product types & Scales. The attributes collected dictate the symbology chosen.

12. Surface Type Symbols

13. Some Surface Types are split into different categories in the original MicroStation maps National Standards may not be in the near future Any standards implemented will be changed if National Standards are created

14. Combine: National Standards Historic Standards Other State DOT Standards Testing Engineers & other users Different Platforms Different Software Packages Reevaluate & Retest Implement

15. Do you think about symbology standards? Do you need them? Would they be/are they organizational, statewide, or national? Do you already have standards? What are some of the challenges you have Encountered? Overcome?
