What This Document Is
This is a set of lecture notes focused on the practical application of Global Positioning System (GPS) technology within the field of geomorphology. Specifically, it details the operation and utilization of a handheld GPS unit – the eTrex Legend – for data collection and analysis. It’s designed to supplement lectures in GY 301: Geomorphology at the University of South Alabama, bridging theoretical concepts with hands-on techniques. The notes cover the device’s functionality, menu navigation, and initial setup procedures.
Why This Document Matters
Students enrolled in geomorphology, environmental science, or related geospatial disciplines will find these notes particularly valuable. They are ideal for anyone preparing for fieldwork involving spatial data acquisition, or needing to understand how GPS data integrates with geomorphological analysis. These notes are most useful when used in conjunction with in-class demonstrations and practical exercises, providing a reference guide during and after field work. Understanding GPS operation is a foundational skill for modern geomorphological research and mapping.
Common Limitations or Challenges
These notes focus specifically on the eTrex Legend GPS unit. While the core principles apply to other GPS devices, the exact menu structures and button functions will vary. This resource does *not* cover advanced GPS data processing techniques, error analysis, or differential GPS methods. It also assumes a basic understanding of coordinate systems and map projections. It is a guide to *using* the device, not a comprehensive treatise on GPS technology itself.
What This Document Provides
* Detailed overview of the eTrex Legend’s physical components and button functions.
* Explanation of the device’s main pages and menu navigation system.
* Guidance on initial setup procedures, including battery installation.
* Information on accessing and utilizing the Main Menu for advanced features.
* Descriptions of key features accessible through the device’s interface.
* An introduction to waypoint creation and management.
