The intent of releasing this document so many years in advance is so we may provide the NSRS user community with insight and as many details as are currently available, as well as to give time for these details to be read and understood and for feedback to be provided back to NGS. The early release of this document, therefore, naturally comes with certain unresolved decisions. Rather than delay the entire document, the term TBD (To Be Determined) has been used herein to indicate where a decision is pending. On the use of the terms “datums” and “reference frames”: Entire chapters of books could be dedicated to the distinction, or lack thereof, between the terms datums and reference frames, however for this paper we will define these terms in this way: In 2022 the NSRS will consist of four terrestrial reference frames and one geopotential datum. From time to time and for the sake of brevity, the four terrestrial reference frames and the one geopotential datum may be clustered under the general term “new datums.” For example, NGS has put information concerning the NSRS modernization on a “New Datums” web page.

  • MAP PROJECTION DESIGN Alan Vonderohe (January 2020) Background
    MAP PROJECTION DESIGN Alan Vonderohe (January 2020) Background For millennia cartographers, geodesists, and surveyors have sought and developed means for representing Earth’s surface on two-dimensional planes. These means are referred to as “map projections”. With modern BIM, CAD, and GIS technologies headed toward three- and four-dimensional representations, the need for two-dimensional depictions might seem to be diminishing. However, map projections are now used as horizontal rectangular coordinate reference systems for innumerable global, continental, national, regional, and local applications of human endeavor. With upcoming (2022) reference frame and coordinate system changes, interest in design of map projections (especially, low-distortion projections (LDPs)) has seen a reemergence. Earth’s surface being irregular and far from mathematically continuous, the first challenge has been to find an appropriate smooth surface to represent it. For hundreds of years, the best smooth surface was assumed to be a sphere. As the science of geodesy began to emerge and measurement technology advanced, it became clear that Earth is flattened at the poles and was, therefore, better represented by an oblate spheroid or ellipsoid of revolution about its minor axis. Since development of NAD 83, and into the foreseeable future, the ellipsoid used in the United States is referred to as “GRS 80”, with semi-major axis a = 6378137 m (exactly) and semi-minor axis b = 6356752.314140347 m (derived). Specifying a reference ellipsoid does not solve the problem of mathematically representing things on a two-dimensional plane. This is because an ellipsoid is not a “developable” surface. That is, no part of an ellipsoid can be laid flat without tearing or warping it.

GRAVITY ……………………………………………… 18 CHAPTER FOUR. NORTH AMERICAN-PACIFIC GEOPOTENTIAL DATUM OF 2022 (NAPGD2022) ……………………... 24 1 FOREWORD This short book was written by Alan Vonderohe in the spring of 2019, with successive chapters being released at intervals over a period of a month. The initial audience for the book was the Wisconsin Spatial Reference System 2022 Task Force, or WSRS2022, a broad-based group organized to address how the National Geodetic Survey’s plans for its new 2022 datums would impact the Wisconsin geospatial community. The chapters are collected here in a single document available to anyone who wants to understand more about the new datums. May, 2019 2 PREFACE In 2022, the National Geodetic Survey will adopt and publish two new geodetic datums that are the underlying bases for positioning, mapping, and navigation. The new datums will impact many human activities. They will have non-negligible positional effects in most of the United States, including Wisconsin. The new datums will also account for positional changes within them over time, an aspect of reality not heretofore comprehensively addressed. This brief book, of four chapters, is intended for a broad audience who seek background information on datums and coordinate systems to better understand the upcoming changes and their possible effects on work activities and products.
