Lesson notes

Learning Objectives

Indicator: 1.2.2.LI.2 - Assess the geospatial data collection tools

By the end of the lesson, learners can:

Compare the advantages and disadvantages of traditional geospatial data collection tools (chain, compass) with modern tools (GPS, remote sensing, mobile apps) using at least three criteria such as accuracy, cost and speed.
Justify the choice of a particular geospatial data collection tool for a given scenario, explaining at least two reasons for the choice.
Evaluate the reliability of geospatial data collected using different tools by identifying potential sources of error in each method.
Recommend the most appropriate geospatial data collection tool for a real-life surveying problem in their community, defending their recommendation in a group discussion.
