The WGS84 CRS has become a global standard for latitude and longitude positions, such as those captured with GPS devices. While no direct transforms have been defined from WGS 84 (G1150) to NAD 83 (CORS96), as stated in 2) the transform to NAD 83 (CORS96) is defined from ITRF00. Error in reproject vector file using GeoPandas. Please make sure that coordinate reference system of your input dataset is assigned correctly - otherwise the resulting KML file may be spatially shifted or wrong. An image which is a composite or mosaic of input images with different projections will have the default projection, which is WGS84 with 1-degree scale. The current values in the input fields are used. And interactive maps such as Google Maps and Bing Maps use the WGS 84 datum. Conversions between NAD83 and WGS84. See the ArcGIS REST API documentation for examples of the structure of various input JSON objects. NMEA is designed to run as a process in the background spitting out sentences which are then captured as needed by the using program. M_Map is a programming toolbox. So for example the "wgs-84" is defined as WGS-84 with the geoid updated by at least for height values. In NZTM the coordinates are 1570634,5180148. Given the assertion in 1), then we can treat WGS 84 (G1150) coordinates as ITRF00 coordinates, thereby creating a path through which the desired transform can be completed.
