ArcGIS Pro: Your questions answered – Part 2

We’re answering your questions from our “ArcGIS Pro: Take Desktop GIS to the Next Frontier” seminar in a three-part series. In Part 1, we covered topics including templates and data storage. In this second post, we cover 3D, notebooks and more.

Thank you to everyone who joined us for the “ArcGIS Pro: Take Desktop GIS to the Next Frontier” seminar. We received many great questions throughout the session. As we didn’t have time to cover all questions during the event, we are answering them through a three-part blog series. In this part, we will cover questions asked during the second session. Watch the recordings.

Q: I have a few Arcade scripts. Can those be used in ArcGIS Notebooks?

A: No, Arcade is used in certain places. Notebooks in ArcGIS Pro use Python.

Q: Is there a license needed to use Jupyter notebooks?

A: Notebooks are included in ArcGIS Online, and in ArcGIS Pro. However, in ArcGIS Enterprise, you do need an ArcGIS Notebook Server role.

Q: Does the notebook auto download the Excel spreadsheet or is that part manual?

A: That's manual, but you can write Python code to read the data from a web source like a Google document.

Q: I had multiple Python scripts from an old process (I exported and edited them in a geoprocessing script from years ago). These models no longer exist. Is there a way to merge multiple Python scripts into one?

A: You could use a Notebook for this.

Q: Can we do space-time analysis on 3D data?

A: Yes.

Q: I’ve been using the forest-based classification and regression in ArcGIS Pro. Is there documentation on how the model works and how to interpret messages when it’s complete?

A: For out-of-bag errors, accuracy checks, etc., yes. Learn more about how forest-based forecast works.

Q: Can we use deep learning for classification of point cloud data?

A: Yes, this will be available in ArcGIS Pro 2.8.

Q: Where does the CO2 emission data come from? How is mesh layer created?

A: ArcGIS Urban can calculate the CO2 emission for any proposed plan. The mesh layers were created by our partner Nearmap, which captures high-resolution aerial imagery in Canada, the US, Australia and New Zealand. They can make the mesh available as an offline delivery in SLPK format or online with an export capability to export the area you want. Nearmap flies and can fix-wing aircraft with patented camera sensors to capture ground aerial features.

Q: How were the meshes created – existing conditions?

A: Drone/photogrammetry, 3D scanners, LiDAR? The mesh is created photogrammetrically. Nearmap has additional 3D products including DSM, DEM and Point Cloud (3 colour), all created from the same source aerial photography, therefore the alignment is perfect. Nearmap captures aerial imagery proactively with a methodical capture plan in the US and Canada so it is available immediately. The mesh is available in a variety of formats including SLPK for Esri. Nearmap’s coverage plan is to capture when clouds are not visible at the altitude they fly at. Resources are positioned accordingly to maximize coverage and capture plans.

Q: How do I access Nearmap Integrated mesh?

A: Learn more about Nearmap.  

Q: Can 3D analysis and mesh be created using LiDAR data?

A: Integrated meshes are created using oblique images captured by aircraft. These images are captured from different angles and are stitched together to create a 3D reality mesh. Nearmap can provide point cloud, DSM, DEM to the same extent. The mesh is not available using LiDAR.

Q: Were the map series pages created manually or were they automated?

A: They were created using map series in ArcGIS Pro.

Q: How does ArcGIS Pro map book functionality compare to the Maplogic product?

A: Read more about MapLogic Layer Manager.

Q: What is the difference between tasks and the notebook?

A: Tasks are used for building wizards using ArcGIS Pro tools and commands, whereas notebooks are like an IDE for Python code.

Stay tuned for part three that will be released shortly. If you haven’t moved to Pro yet, learn more about migrating to ArcGIS Pro. Until next time!
