This is and Introductory lecture to machine learning and its background.
This is theory about Land Use Land Cover and what are its importance.
This lecture is about change detection and is the purpose of doing it in geospatial analysis.
These are tools you need to have for you to learn this course effectively.
This lecture will brush you through the results that we shall get at the end of the course.
Here, you will import the shapefile for the region of interest or the study area.
Here, you will learn how to import satellite imagery data from Google Earth Engine to your code editor.
Apply filter functions in Google Earth Engine to refine data by bounds, date, and cloud cover, then print raw Landsat 8 data for visualization.
Create training data in Google Earth Engine by labeling classes (built up, bare land, crop land, forest, grassland) and importing them as feature collections for supervised LULC.
Finalize a supervised LULC classification in Google Earth Engine by applying a color palette and visualization parameters, exporting the classified image, and preparing for accuracy assessment.
Add fields to the attribute table of the 2017-2020 classified image to support change detection and analysis, including creating LULC_17_20 and a value one field, then edit and save.
Carry out change analysis by converting the 2017–2020 classified raster to polygons with raster to polygon tools and save outputs for area calculations, then repeat for 2021–2024.
Dissolve grid codes for 2017–2020 polygons to produce a single grid code layer, using raster to polygon data and geoprocessing dissolve, mapping codes to land cover classes.
Create and populate fields for the 2017–2020 LULC classes, then set the correct UTM zone and calculate area in square kilometers for each class to support change analysis.
This lecture will teach you how to intersect the attribute tables of both polygons for 2017-2020 and 2021-2024.
Unlock the power of Google Earth Engine (GEE) in this complete guide to Supervised Classification for Land-Use and Land-Cover (LULC) mapping and Change Detection analysis. This hands-on course is designed for students, researchers, GIS professionals, and anyone interested in remote sensing and geospatial analysis.
You will learn how to use Google Earth Engine to perform supervised classification for accurate land-use and land-cover mapping. Step by step, we explore data preprocessing, training sample creation, classification algorithms, and accuracy assessment to ensure reliable results.
Beyond classification, the course covers Change Detection analysis using ArcMap (ArcGIS Desktop), enabling you to identify and quantify environmental changes over time such as urban growth, deforestation, agricultural expansion, and water body variations.
To enhance interpretation and presentation, you will also learn how to use Excel for advanced data visualization, including charts, tables, and comparative statistics to clearly communicate your findings.
By the end of this course, you will have a solid understanding of:
Supervised Classification in Google Earth Engine
Land-Use Land-Cover mapping techniques
Change Detection using ArcMap
Accuracy Assessment for LULC results
Data visualization and reporting in Excel
This course provides a practical, real-world workflow for performing LULC mapping and change detection projects from start to finish, giving you the skills needed to apply remote sensing and GIS in environmental monitoring, urban planning, agriculture, and natural resource management.
