New Learn Lessons

A Learn Lesson is a step-by-step tutorial that uses a real-world scenario to introduce key ArcGIS tools and workflows. Here's a roundup of new lessons in the Learn ArcGIS Gallery that have appeared in the last month.

 

Analyze and visualize property valuations (ArcGIS Online, ArcGIS Insights desktop)

As a property assessor for Bloomfield Township in Michigan, you need to analyze and ground-truth home values to ensure that property taxes are distributed fairly. You'll use ArcGIS Insights instead, so you can visualize and analyze your data interactively.

In this lesson you'll build a workbook that visualizes your data with a map, charts, indicator values, filters, and a table. You'll use the workbook to investigate sales ratios and outliers in the data to help determine if properties in Bloomfield are assessed correctly. You'll share your results with the other assessors in your office both as an interactive visualization tool, and as a model that they can reuse with other datasets.

 

Apply Exploratory 3D Analysis tools (ArcGIS Pro)

This lesson contains a mix of small-, medium-, and large-scale urban environments. The interactive analysis tools use graphic effects rendered in the scene to highlight spatial properties, such as visibility and proximity. These effects are temporary and based on which layers are currently visible. You can export images and animation videos that show the interactive analysis objects in place. With animations, you can even have the analysis object—such as the slice, line of sight, or viewshed—move and resize itself over the course of the video.

In this lesson, you will use the Exploratory 3D Analysis tools View Dome, Slice, and Viewshed in ArcGIS Pro.

 

 

Build a 3D cityscape by themes (ArcGIS Pro)

In this exercise, you will be working with simple GIS data for a city–building multipatches, parcel footprints, water main lines, city-managed tree points, and regularly spaced wind sample points to create a thematic representation of different aspects of the city. In this lesson, you will use color to represent 3D objects as a theme, match thematic representation across multiple layers, and use thematic extrusion, size, shape, and orientation on 3D layers.

 

 

 

Create realistic 3D urban scenes (ArcGIS Pro)

As an urban planner, you have been tasked with creating multipatch features and performing texture editing for an urban area. As part of the workflow, you will extrude, edit, and symbolize the building footprints. After converting building footprints to multipatch features, you will apply textures to the buildings to make them as realistic as possible.

In this lesson, you will extrude, edit, and symbolize building footprints; add and configure preset trees; set a constant elevation; configure a 3D grid to create a new 3D feature; create a multipatch feature; and perform textured editing.

Model a 3D city block (ArcGIS Pro)

In this lesson, you will be working with GIS data for the city of Naperville, Illinois. This includes building footprints, city-managed street trees, furniture, and points of interest that will be used to create a 3D view. You will also consider how your intended audience will use the scene. You will extrude building footprints as simple 3D symbology, use procedural symbols for advanced 3D symbology, add a preset trees layer by height, add 3D street furniture with consideration to furniture rotation, and create bookmarks to help your audience navigate the scene.

Model how land subsidence affects flooding (ArcGIS Pro/ArcGIS Spatial Analyst extension)

Flooding causes catastrophic damage around the world each year. When combined with land subsidence, flood inundation becomes more severe. The Netherlands is no stranger to these phenomena, partly due to its low-lying location.

In this lesson, you'll take on the role of an Amsterdam municipal employee investigating how land subsidence can change the spatial and financial impacts of a flood. First, you'll use spatial analyst tools to preprocess the provided raster dataset. Then, you'll determine flood extents and estimated damage. Finally, you'll compare damage that would take place today and in 2050 based on projected land subsidence estimates.

Classify power lines using deep learning (ArcGIS Online/ArcGIS Pro/ArcGIS 3D Analyst/Deep Learning Libraries/Excel)

In this lesson, as a GIS analyst for an insurance company, you will use a deep learning model to conduct a risk assessment analysis of power lines using lidar (light detection and ranging) data. You will analyze an area in Northern California that has potential fire risk due to trees in close proximity to power lines.

You will use ArcGIS Pro to create and train a deep learning model to identify the power lines from a lidar point cloud. Deep learning allows you to train a model using a sample dataset and apply the model to other similar areas. You will assess which model resulted in the most accurate results and use it to classify the lidar points that are power lines.

 

Improve campsite data quality using a relationship class (ArcGIS Online/ArcGIS Pro)

Park visitors using a site have reported inconsistencies between posted campsite information for two of the most popular national parks in the country, Yellowstone, and Grand Teton National Park. 

In this lesson a regional GIS Specialist is tasked with helping improve campsite data quality in Wyoming. The specialist will initially address the loss of data at the park level by creating joins and relates to incorporate associated records, and will then inspect and create a relationship class between campsites and campgrounds. Finally, the specialist will publish the curated data as a web map that can be shared on a website and in a app by park authorities.

 

Design custom symbols to map wildfires (ArcGIS Online)

How do you design effective symbols for web maps? In this lesson, you'll re-create the custom symbology of the USA Current Wildfires layer from ArcGIS Living Atlas of the World.

You'll learn about the design criteria that contributed to the symbol, and how to build the Arcade expressions that allow the symbol to work on changing backgrounds, with changing data, and at changing scales. By re-creating the symbology of the wildfire layer, you'll learn skills that you can apply to your own data to build effective and cartographic web maps.

 

 

 

Track vehicle behavior to apprehend a suspect (ArcGIS Pro Intelligence)

Classifying movement events is an analytical technique that identifies how people and things move through an environment. Determining where individuals make turns or change speed provides insights into movement patterns that can be used for actionable responses.

In this lesson, you're a law enforcement officer planning a raid on a suspected criminal while they move from one area to another in a vehicle. To ensure the raid is successful, you'll analyze vehicle movement behavior to determine when the suspect's vehicle is most likely to slow down or stop. You'll perform the analysis in ArcGIS Pro Intelligence, a customized version of ArcGIS Pro tailored for intelligence workflows.

New Learn Paths

A Learn Path is sequenced set of resources for learning about a particular topic. Here's a roundup of some new paths in the Learn ArcGIS Gallery that have appeared in the last month.
