Students learn how to evaluate the accuracy of a classification they perform in this tutorial.
A summary of learning activities for the biosphere investigation area.
Students learn how to evaluate the accuracy of a classification they perform.
Using MultiSpec, students compare two images of their GLOBE Study Site; one from the 1990's and one from the 2000's, to determine how the land cover has changed in that time span in this tutorial.
Students use MultiSpec to perform unsupervised clustering of their Landsat TM image and then assign MUC classes to every cluster to create a land cover map.
Students use the satellite image of the GLOBE Study Site and their knowledge of remote sensing to decide where a new hospital should be located.
Students classify land cover by visually examining their site as well as mapping and recording ground cover onto graph paper as they walk across their site. Students will use a GPS to locate the site in addition to photographing their site.
Students use the satellite image of their GLOBE Study Site to become familiar with the different types of land cover in their area.
Students will analyze visualizations and
graphs that show the annual cycle of plant
growth and decline.
Using MultiSpec, students compare two images of their GLOBE Study Site; one from the 1990's and one from the 2000's, to determine how the land cover has changed in that time span.
Students make a collection of leaves and then discover how a hierarchical classification system is developed by sorting and organizing their leaves according to a set of labels and rules which they specify.
Students outline and label different areas of land cover as seen on their Landsat TM image to create a land cover map.
Students outline and label different areas of land cover as seen on their Landsat TM image to create a land cover map in this tutorial.
To help students understand the connection between remote sensing technology, computer imagery and land cover assessment and to demonstrate how a satellite sensor relates information to a computer
To familiarize students with the importance of perspective and introduce students to various scales of remotely sensed data.
To familiarize students with the concept of modeling as it is related to remote sensing and to the process of digitizing images.
To help students determine that a system's boundaries are based upon the question(s) a scientist wants to answer.
To investigate the idea that every dynamic system has energy and matter in several different forms. Inputs and outputs will vary depending upon the physical components of the site, the plant and animal life, the determined boundaries or scale of the study and the season.
Students correlate graphs of vegetation vigor with those of temperature and precipitation
data for four diverse ecosystems to determine which climatic factor is limiting growth.
Students find another GLOBE school that reported the same MUC class and systematically compare the other GLOBE measurements that they each reported.
