A Learn tutorial is a step-by-step workflow that uses a real-world scenario to introduce key ArcGIS tools, products and modern best practices. Here's a roundup of new tutorials in the ArcGIS tutorial Gallery that have appeared in the last month.
In this second tutorial of the Explore satellite Imagery for Africa you will continue to learn about satellite imagery and remote sensing, but you now focus on identifying, delineating, and extracting change. You will look at three real-life examples: a wildfire in Kenya, water inundations in Chad, and a fast-growing city in Ghana. In all three cases, you will extract change, assess how the landscape was impacted, and understand how your analysis could be used to address resulting challenges.To perform your analyses, you'll use the Digital Earth Africa Explorerapp, the result of a collaboration betweenEsriand theDigital Earth Africa program. The app enables users to seamlessly explore some of the Digital Earth Africa satellite imagery and other earth observation data for the African continent. You'll also learn how to export the data extracted to a local file orArcGIS Online for further use.
Many workflows in GIS consist of repetitive tasks. Geoprocessing tools can be run using the Geoprocessing pane in ArcGIS Pro, but they are also available in Python as functions of ArcPy. This allows you to automate repetitive geoprocessing tasks using a Python script. In this lesson, you will write a Python script to check the coordinate system of multiple datasets and use that information in the script to determine how the dataset should be processed.
In this third tutorial of the Explore satellite imagery for Africa series, you will continue to learn about satellite imagery and remote sensing. You will now dig deeper and become familiar with essential concepts of imagery analysis, such as spectral profiles and signatures, spectral scatterplots, and spatial resolution. You will also continue to explore real examples on the African continent, such as an oasis in Egypt, mangrove forests in Zanzibar, and a city in South Africa.
To perform your exploration, you will use the Digital Earth Africa Explorer app, which is the result of a collaboration between Esri and the Digital Earth Africa program. The app enables users to seamlessly explore some of the Digital Earth Africa satellite imagery and other earth observation data for the African continent.
Climate change has caused a rapid and alarming decline of polar sea ice in the twentieth century. Since 1978, this decline has been tracked by satellites, resulting in large amounts of data. In this five-part tutorial series, you are a cartographer who needs to make an educational poster-style map to communicate the ongoing loss of sea ice in the Arctic. Your job is to turn a large dataset into a map that tells a meaningful story. You'll learn how to employ cartographic skills in ArcGIS Pro to make a professional map layout.
