Lesson 4
Topographic Maps
Topographic Maps
Overview
Topographic maps show ground relief and features for design and planning purposes. Creating accurate, readable topographic products requires understanding of cartographic principles and client needs.
Learning Objectives
- Design effective topographic maps
- Apply appropriate contour intervals
- Symbolize features correctly
- Meet accuracy and content requirements
Key Concepts
Map Design
Effective topographic maps include:
- Appropriate scale selection
- Clear contour representation
- Feature symbolization
- Legend and notes
- Reference information
Contour Representation
Principles of contouring:
- Appropriate interval selection
- Index and intermediate contours
- Depression and supplemental contours
- Contour smoothing
- Accuracy considerations
Feature Symbolization
Representing physical features:
- Standard symbols
- Custom symbols when needed
- Legend explanation
- Clear differentiation
- Appropriate density
Quality Standards
Accuracy and completeness:
- Positional accuracy standards
- Vertical accuracy specifications
- Completeness requirements
- Attribution standards
Key Terms
- Contour Interval: Vertical distance between contours
- Index Contour: Labeled contour at regular intervals
- Planimetric Feature: Horizontal feature without elevation
Practice Questions
- What factors determine the appropriate contour interval?
- How should topographic map accuracy be stated and verified?
