High-accuracy data collection has come a long way since the USA launched the first GNSS constellation, GPS, in the 1970s. Today, all you need to get started with submeter or centimeter data collection is a smart device, a collection app, and a GNSS receiver that works with both.
WaterOne in Kansas was stuck in a legacy technology mess. Their GNSS handhelds required time-consuming, end-of-day manual labor. And worse, the interfaces frustrated staff. The utility decided to swap the old technology in favor of a device-agnostic, web-GIS-first technology kit. By implementing the ArcGIS platform, deploying Arrow 200 GNSS receivers, and moving to a platform-based approach to information collection and sharing, WaterOne created an affordable, high-accuracy location solution that staff enjoyed using. Here's their story.
Unmanned air vehicles can collect tremendous data and imagery to produce high-precision orthophotos. But how can you set up your own GCPs to ensure precision and accuracy? This article from the Eos June 2017 issue explains how.
How to know if your mobile device GNSS accuracy is correct — or if your device is lying to you? It’s really cool when your mapping app displays the estimated accuracy of the GNSS receiver you are using. Conversely, there’s nothing more frustrating than your mapping app showing a GNSS estimated accuracy that is wrong .
Is your mobile device lying to you about GPS accuracy? No, but in this Eos April 2017 issue we'll show you how to make your receiver and mobile device talk the same language. Plus, we'll also show you how to pair your Arrow via Bluetooth so you can start recording high-accuracy data today.
California State University - Monterey Bay (CSUMB) needed updated as-builts and field asset data. The university needed a solution to record high-accuracy (centimeter) horizontal and vertical (aka elevation) data. Using the Eos Arrow 200, iPads, and Collector for ArcGIS, CSUMB was able to map its most sensitive field assets. Then, the university team used the geoid model and ArcGIS for Desktop to convert its elevation data into usable field data. The asset records will now help the university provide contractors and field surveyors with high-accuracy field data for construction, demolition, and other projects in the future. See how CSUMB deployed the solution.
