What's New in Learn ArcGIS September 2021
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.
Animate a historical ship race (ArcGIS Pro)
In this lesson, you will create a video depicting a simulated virtual sailing ship race from 1770 by plotting the logged positions of the ships as they crossed the Atlantic from La Coruña, in Spain, to San Juan, in Puerto Rico.
Animate the Oso mudslide (ArcGIS Pro)
On March 22, 2014, after a month of heavy rainfall, a mountain gave way near Oso, Washington; the resulting and historic mudslide tragically killed 43 people. In this lesson, your task is to call attention to the deadly event by creating a 3D fly-through animation showing the area before and after the mudslide.
Enable an inbox for a census survey (ArcGIS Survey123 Connect/ArcGIS Pro/ArcGIS Online)
In this lesson, you'll enable the inbox feature for a census survey form. First, you'll publish a survey using ArcGIS Survey123 Connect. Then, you'll combine the survey with a feature layer of building points in ArcGIS Pro. Last, you'll enable the inbox and test its functionality by assigning specific buildings to enumerators.
Collect 3D features from a stereo map (ArcGIS Pro)
Using a collection of stereo imagery loaded into a mosaic dataset, you will use stereo viewing and mapping in ArcGIS Pro to collect new 3D rooftop point features. This will help establish a pattern that city officials can use to visually analyze imagery and compile three-dimensional (3D) features that can be used to update existing data and determine whether bylaws are being broken.
Analyze impacts of congressional redistricting with ArcGIS Insights (ArcGIS Insights/ArcGIS Online)
You will use ArcGIS Insights to map and compare the various redistricting plans and use different charts to analyze the demographic information in the proposed plans. Once you have created your maps and charts of the plans, you will share your work so that stakeholders and decision makers can access it online.
Design a 3D local scene (ArcGIS Pro)
Maps and scenes can both use illumination to achieve different effects. Maps use illumination mainly to make maps look more three dimensional by applying shaded relief or hillshades. A scene, however, needs a light source to illuminate it, and you can configure this light source to achieve different effects within the scene. Having a good understanding of these settings will allow you to add an extra level of quality to your 3D scenes. In this lesson, you'll use illumination settings, including sun position, shadows, and atmospheric effects; enable the north arrow and on-screen Navigator control; view content in a local and global scene; and work with parallel view mode to display features differently and more effectively.
Convert a list of historic places into a map (ArcGIS Online or ArcGIS Pro)
In this lesson, you'll reformat a list of locations as a table. Then you'll geocode the table in ArcGIS Online or ArcGIS Pro. Geocoding is a process that converts location names to map coordinates. You'll review the matches produced by the geocoding process and fix any that are out of place. Finally, you'll apply a few edits to your new map before sharing it with your students.
Convert a static map into a web app and print map (ArcGIS Online/ArcGIS Pro/ArcGIS Dashboard)
In these paired lessons you'll learn (1) how to share a web map from ArcGIS Pro, control which basemaps appear as you zoom in and out, and build a dashboard application that students can use to explore the map on a desktop or mobile device and (2) how to open a web map that you created in ArcGIS Online in the ArcGIS Pro desktop app. You'll change the map's projection, create a layout, adjust the labels, and export the map as a PDF.
Improve interpolations to map temperature (ArcGIS Online/ArcGIS Pro/ArcGIS Geostatistical Analyst extension)
With a set of sample temperature measurements, you can interpolate temperature values over an entire area to predict temperatures in locations where there are no samples. You can use geostatistics to make this interpolation, but the results will not be accurate if you do not have enough sample locations. You will create a temperature map for California's Sierra Nevada mountain range. In doing so, you will interpolate datasets that contain a different amount of points to see how accuracy improves when there are more samples. Because temperature is affected by elevation, you will include an elevation variable in your prediction to see if the temperature predictions improve when considering elevation. You can use either an ArcGIS Online or ArcGIS Enterprise account to sign in to ArcGIS Pro, depending on your set up.
Map ozone with a 3D interpolated fence (ArcGIS Online/ArcGIS Pro/ArcGIS Geostatistical Analyst extension)
You will map ozone concentrations in a 3D vertical fence along the Interstate 10 highway, from Santa Monica on the coast to Palm Springs in the desert. You will use a Python script tool, built using geostatistical methods that can interpolate phenomena over a continuous surface from discrete input data. Normally, geostatistics is used to map concentrations horizontally. You will create a vertical interpolation to understand how ozone changes with height. You will also symbolize the fences layer and configure the pop-up to only display certain attributes. You can use either an ArcGIS Online or ArcGIS Enterprise account to sign in to ArcGIS Pro, depending on your set up.
Use 2D data in a 3D scene (ArcGIS Pro)
The City of Portland has undertaken a project to update and modernize its citywide database by including more 3D data and capabilities. This project includes displaying orthophotos and draping layers over the surface to provide a map user with the ability to verify spatial alignment and 3D representations of real-world objects.
In this lesson, you'll shade a surface to emphasize variations in relief and drape content on the surface. You'll also add 3D symbology to layers.
Visualize D-Day in 3D (ArcGIS Earth)
In this lesson, you will re-create the scene for the initial landing at D-Day using KMZ, KML, and OBJ files in ArcGIS Earth. By using the Interactive Analysis tools in ArcGIS Earth, you will be able to understand the viewshed range of different vehicles and weaponry. After completing this lesson, you will be able to employ similar techniques to re-create other battles for instructional purposes, or to gain a general overview of a battle plan using ArcGIS Earth.
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.
Create and edit redistricting plans (ArcGIS Redistricting)
Learn how to use the tools in Esri Redistricting to create and edit plans.
Analyze and review redistricting plans (ArcGIS Redistricting)
Analyze plans with thematic maps, run reports to evaluate demographic distribution, and verify the integrity of redistricting plans.
Collaborate with other users and groups using Esri Redistricting (ArcGIS Redistricting)
Take advantage of collaboration tools in Esri Redistricting to share and publish plans and engage with stakeholders.
