This transformation is based on utilizing GEOID09 to transform to NAVD88 and then to CRD. GEOID09 was the hybrid National Geodetic Survey (NGS) GEOID utilized for the CRD grid development. . [CRD] The Columbia River Datum (CRD) is the adopted fixed low water reference plane for this area. CRD is a U.S. Army Corps of Engineers non-tidal datum defined at distinct river miles relative to NAVD88, and is used as chart datum above river mile 23 on the Columbia River. Datums are computed using observations from the low river stages of the year, generally August through October due to the masking of the tidal signal from strong seasonal river runoff during other portions of the year. Depending on river flow, water levels can be significantly higher than Columbia River Datum. [CRD] Initial testing of the implementation of CRD in VDatum provides us with some insight to the uncertainty of these transforms. The VDatum implementation was tested against Center for Operational Oceanographic Products and Services (CO-OPS) published data at the following stations: * Skamokawa * Wauna * Longview * St. Helens * Vancouver Tidal Datums relative to CRD provided differences ranging from 2.5 centimeters at St. Helens to 7.2 centimeters at both Longview and Vancouver. Transforming between tidal datums resulted in differences ranging from a few millimeters to 1.1 centimeter at Longview. Larger uncertainties can be expected between Local Mean Sea Level and NAVD88, due to the transformation roadmap implemented for the West Coast tidal datums, utilizing xGEOID20b and how a user may want to define the transform of NAVD88 based on a particular NGS hybrid GEOID. Uncertainties for transforms between Local Mean Sea Level and NAVD88 of 2-13 centimeters can be expected. CRD is accessed through the West Coast Regional Model as illustrated below. [CRD02] ________________________________ VDatum Tidal API Retirement with transition to full VDatum API We have retired the VDatum Tidal API. The full VDatum API has been transitioned from beta to production. The full VDatum API should have all the functionality as the VDatum Tidal API and more. If you have any concerns, please contact us at [log in to unmask]<mailto:[log in to unmask]>. ________________________________ Retirement of Raster Formats (GeoTIFF and ERDAS IMG) We will be retiring the following raster formats in the File Conversion tab of VDatum with the release of Version 4.6: * GeoTIFF * ERDAS IMG This will allow us to focus on point conversions allowing for more efficient processing and to support multiple operating systems consistently.
