A quick guide to the Surveyor Bookmark application:

Includes a web mapping interface geared to the Surveyor community. Contains the below layers among many more for reference

National Geodesic Survey (NGS) datasheets: Feature Service for NOAA's National Geodetic Survey Datasheets. This data contains a set of geodetic control stations maintained by the National Geodetic Survey. Each geodetic control station in this dataset has either a precise Latitude/Longitude used for horizontal control or a precise Orthometric Height used for vertical control, or both. The National Geodetic Survey (NGS) serves as the Nation's depository for geodetic data. The NGS distributes geodetic data worldwide to a variety of users. These geodetic data include the final results of geodetic surveys, software programs to format, compute, verify, and adjust original survey observations or to convert values from one geodetic datum to another, and publications that describe how to obtain and use geodetic data products and services.

OPUS Shared Solutions: This data layer contains user-contributed geodetic control marks with shared GPS observations, which provide local ties to the National Spatial Reference System. This data layer is updated every week night. For more information about OPUS please visit the About OPUS page. If you would like to upload your own opus solution please visit our upload opus solution page. For additional information about shared solution please visit our shared solutions page.

The NOAA Continuously Operating Reference Stations (CORS) Network (NCN), managed by NOAA/National Geodetic Survey, provide Global Navigation Satellite System (GNSS) data, supporting three dimensional positioning, meteorology, space weather, and geophysical applications throughout the United States.
Surveyors, GIS users, engineers, scientists, and other people who collect GPS/GNSS data can use NCN data, acquired at fiducial geodetic control stations, to improve the precision of their positions, and align their work within the National Spatial Reference System (NSRS). NCN enhanced post-processed coordinate accuracies can approach a few centimeters, both horizontally and vertically.
The NOAA Continuously Operating Reference Stations (CORS) Network: The CORS network is a multi-purpose, multi-agency cooperative endeavor, combining the efforts of hundreds of government, academic, and private organizations. The stations are independently owned and operated. Each agency shares their GNSS/GPS carrier phase and code range measurements and station metadata with NGS, which are analyzed and distributed free of charge.

NYS DOT Roadway Inventory Data: which includes State Highway Number (SH #)

Many more, such as: Civil Boundaries, Streets, Elevation Contours, Building Footprints with address information, publicly available Tax Parcels, Hydrography (great for cartographic purposes!), Statewide Hillshade, Statewide Latest Digital Elevation Model, and the Latest and Greatest Orthoimagery from the great folks at NYS ITS Geospatial Data Services' Orthoimagery Program!

We also offer a Basic Viewer App within this same interface for viewing many layers, unrelated to surveying.
