http://catalog.sierracollege.edu/course-outlines/geog-0086/

Catalog Description DESCRIPTION IS HERE: Hours: 18 lecture Description: Global Positioning System (GPS) theory and techniques, GPS field collection, GIS integration and publishing web maps. Discussion of state-of-the-art hardware and industry-standard software used by GIS professionals to prepare, collect and process spatial data. Data collected during class culminates in a comprehensive GIS mapping project used for analysis. (CSU) Units 1 Lecture-Discussion 18 Laboratory By Arrangement Contact Hours 18 Outside of Class Hours Course Student Learning Outcomes List 5 core steps on how a GPS works. Determine and identify critical setup items needed before field collection of GPS. Develop data dictionary on scratch paper then computer software keeping in mind an iterative process. Mark and navigate to GPS waypoints. Differentiate correct collected field data. Course Content Outline I. Introduction to GPS technology A. GPS common uses B. How technology emerged C.

Introduction to common and professional (ESRI) software C. Planning goals and desired outcomes for GIS III. Grid systems and map reading overview A. Lat./Long, UTM, State Plane, Township & Range B. Datum and control points C. Common Projections D. Time systems IV. Setting up a data dictionary and geodatabase using online portal A. Define geographic features, attributes, values B. Define specific and consistent input fields (categories, text, etc.) C. Set-up GPS software (e.g., ESRI Arc Collector) for iPad units V. Download and integrate GPS data into a GIS A. Retrieve/Download collected data online B. Import data into desktop application (ArcMap, ArcPro, Google Earth) C. Work with GIS software to create database D. Evaluate GIS database, analysis and mapping goals E. Student final mapping project for a GIS Course Objectives Course Objectives 1. List core mechanisms to how a GPS works, including in-depth discussion of each set-up steps. 2. Compare and contrast different levels of GPS data collection related to accuracy and the GIS setup. 3. Hardware/software setup needed before heading into the field for data collection. 4. Establish an interactive process for developing a data dictionary, focusing on the the data to be collected. 5. Distinguish which feature classes are easiest and most difficult to collect, edit and process for output to the GIS. 6. Manage in-office software and online applications (such as ESRI products) to import data and create maps. 7. Create final GIS mapping project used for analysis. Methods of Evaluation Objective Examinations Problem Solving Examinations Projects Skill Demonstrations Reading Assignments 1. Read online GPS constellation and operation information provided prior and during class time. Be prepared to discuss in class. 2. Set up maps in ESRI online maps for unit collection using user manual (or related material). Special attention must be focused on coordinate systems and the datum, data dictionary collection, file management (different formats), data collection operations, final output techniques, such as producing maps for the web. Writing, Problem Solving or Performance 1. Summarize the logical and necessary elements of how a GPS works (triangulations, distance, accurate clock, etc.). Then investigate each item in more detail, for example, how is distance determined using timing? 2. Determine several ways to achieve sub-meter or near accuracy -- both in the field (real-time) and in the office (differential correction) with higher end GPS units. Provide examples of each application, for example, how the airline industry needs Wide Area Augmentation Systems (WAAS) accuracy for foggy landings (vertic. accuracy). Other (Term projects, research papers, portfolios, etc.) 1. GPS final mapping project Methods of Instruction Lecture/Discussion Distance Learning Other materials and-or supplies required of students that contribute to the cost of the course.
