Important 3D Terminology

Getting the z-terminology straight

Maps and Scenes

GIS content can be displayed in 2D or 3D views, and there are a lot of similarities between the two modes. For example, both contain GIS layers, both have spatial references, and both support GIS operations such as selection, analysis, and editing.

However, there are also many differences. At the layer level, telephone poles might be shown in 2D as brown circles, while the same content in 3D could be shown as volumetric models—complete with cross members and even wires—that have been sized and rotated into place. At the scene level, there are properties that wouldn’t make sense in 2D, such as the need for a ground surface mesh, the existence of an illumination source, and atmospheric effects such as fog.

This scene shows the global pattern of airports and the interconnected air traffic routes using the openflights.org data.

Three Things You Can Do with Real-Time Dashboards

Real-time dashboards provide a way to absorb and make meaning from the torrent of real-time information that is used to drive so many decisions. Dashboards are your secret weapon for visualizing and putting meaning behind all of these real-time feeds.

Acquire Real-Time Data

A utility organization may want to visually represent the live status of its network with information that is captured by sensors in the field. While the sensors on the network are not physically moving, their status and the information they send changes very rapidly. Radio-frequency identification (RFID) is being used in a wide variety of environments to keep track of items of interest. Warehouses and logistics companies use RFID to track and monitor inventory levels. Hospitals use it to track equipment to make sure it has gone through proper cleaning procedures before entering another patient’s room.

The Future of Cloud-based GIS Analysis with ArcGIS Online

The cloud is growing in importance for GIS professionals, with cost efficiency, scalability, and flexibility as major drivers. We can see the beginnings of cloud options for many organizations with the ability to run ArcGIS Server in the cloud and also via Esri’s managed services in the cloud.

On a similar, but yet somewhat different and exciting frontier, ArcGIS Online is a key part of the Esri vision for ArcGIS in the cloud. However, up until recently the focus for ArcGIS Online has been on the data part of GIS – making and sharing maps, apps, and other resources, and organizing online communities.
