Supporting GEOID models enables Arrow GNSS receivers to collect high-accuracy, survey-grade vertical datum with any software. In other words, you can now use your Arrow GNSS receiver with any data collection software in the world, and benefit from accurate orthometric heights. Our Arrow receivers will output accurate GNSS elevations no matter which data-collection software you use to capture it.
What is the difference between the ellipsoid, mean sea level, geoid, geoid height, and orthometric height — and which one is right? Learn how the ellipsoid elevation your GPS receiver captures relates to the geoid, how to convert between the two so you can start using your data, and why most GPS receivers don't output the orthometric height you rely on.
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.
