Welcome to the GPS on Bench Marks Temporary 2019 Web Map. This provides a view of 2900 priority marks that were not collected in the 2018 list but can still help improve the Transformation Tool that will be created for NAPGD2022.
Priority A Mark with n observation(s) requested
Priority B Mark with n observation(s) requested
Priority mark clusters with # listed.
Priority A are marks we need to either fill gaps or resolve conflicting existing information. These bench marks would provide the most value to improve geoid modeling with new observations.
Priority B are marks where we need to confirm the relationships suggested by other data in the area... We could build the model without them but we'll have more confidence in the geoid modeling if we have more data.
