In 2022, NGS will be replacing the US horizontal and vertical datums (NAD 83 and NAVD 88). In this talk we will review the need and process for these changes. We will begin with a brief discussion of the history of the North American Datum of 1983 and the North American Vertical Datum of 1988, and the reasons for their ongoing evolution. We will then discuss what activities are being undertaken to ensure a smooth transition to include new State Plane Coordinates.
Spatial information is a key component of many precision agriculture applications. From GPS/GNSS positions used for auto-guidance, to field maps for precise prescriptions, the accuracy of positions, as well as the accuracy of meta-data describing the spatial information is imperative to realize the full benefits of precision agriculture. The importance of spatial data providers and consumers (e.g. software developers) understanding the intricacies of datums, coordinate systems, and projections is ever-increasing as more and more data from different sources are integrated together.
This presentation will provide background on the make-up of spatial data, GPS/GNSS usage in precision agriculture, and how this relates to precision agriculture data from various sources. The effects of any datum / coordinate-system / projection misunderstanding, or mis-match will be discussed in general, and also tied to the NSRS2022 datum update.
