Introduction

Since its beginnings over 50 years ago, GIS has relied on 2D maps. They were what we created and where we performed all our analyses. Recently, this is changing. More and more, we are having to take the third dimension, Z, into account. This is because the world is becoming more crowded. Our infrastructure is stacking up upon itself, both above ground and below. So, the need to track and view data in 3D is increasing. Supporting technologies, such as Light Detection and Ranging (LiDAR), Unmanned Aerial Vehicles (Drones/UAS/UAV), and increasing computer power are also adding to this push. 

As you have seen if you have completed previous recipes in this book, ArcGIS Pro is a very powerful tool for visualizing and analyzing data. However, up to this point, we have been working in a 2D environment. While we can do a lot in 2D, it does have limitations because we live in a 3D world. ArcGIS Pro brings new 3D capabilities to the table that we have not had in previous desktop GIS applications...
