Arbitrating Planned Change FAR Part 77: power to control navigation hazards limited FAA often is slow to learn of the existence of a hazard Is this a problem along coastlines and in waterways? Can NOAA & FAA work more effectively in this regard?
|
From page 28... ...
The NGS state advisors, for the most part, are of little value to the geodetic and mapping industry. We believe that many of them are not well educated in the subject and only tend to mislead the land surveying community.
|
From page 29... ...
This provides an economical QA/QC on geodetic control projects, provides cities and counties with qualified subcontractors and thus a quality product, and provides a means by which to disseminate the data to the public. The current time-frame on getting a blue-book project accepted by NGS is far too long.

Strategic Goal #hi One federal agency redefining GPS orbital information should be sufficient to support the user community. At present, do NGS, USGS, DMA, Scripps collaborate on this?
|
From page 31... ...
~ fee! that in order for NOAA to reach its goals and provide the required data to the user community, well qualified companies must be involved.
|
From page 32... ...
in some jurisdictions the law may recognize record coordinates as evidence of position but will nearly always hold to local monumentation over geodetic definition. · As GPS technology expands, both in its development and application by the surveying profession, legal institutions may in the future recognize record coordinates as controlling parcel location · Control and data collection surveys for design professionals and the construction and title transfer industries are ordinarily performed with reference to local vertical datums and horizontal control systems in order to relate to local infrastructure.
|
From page 34... ...
Area mapping, resource inventory, multi-states infrastructure construction and management, geographic information systems, and other activities in which geodetic surveying is to be a central component will make intense use of the Federal Base Network. Cooperative Base Networks and User Densification Networks will become a logical extension of the FBN.
|
From page 35... ...
In general, the proposed NSRS is compatible with geodetic control currently used by local surveyors (NGS's historical control networks or control based on these networks)
|
From page 36... ...
A national spatial reference system with appropriate federal support and maintenance is the only practical means to fulfill the expanding and critically required spatial referencing needs of the 2ist century.
|
From page 37... ...
? years by archiving portions of the existing NGRS and creating a new NSRS consisting Specifics should be added to make this goal meaningful; e.g., define the NSRS; add time frames; explain disposition of existing NGRS data; emphasize the role of State Geodetic Advisors, etc.
|
From page 38... ...
This coordination should be a responsibility of the State Geodetic Advisor. - It is requested that an accuracy standard of B-order, class II (~:500,000)
|
From page 40... ...
NGS State Geodetic Advisor Program: For over 100 years, surveyors and others have relied almost totally on NGS for geodetic control. The draft strategic plan makes a significant shift of responsibilities from the federal to the state and local levels.

VEHICLE NAVIGATION * These systems require a reference system like NOAA's National Spatial Reference System.
|
From page 42... ...
Unless a high accuracy spatial data reference system is established, Federal, state and local governments and the private sector win spend {ens of billions of dollars in developing uncoordinated, incompatible local data bases." 7.

FORCES ACTING ON NOAA's NSRS User community changing from - Suppliers to consumers - A few 10's of thousand to millions. Convergence of digitally based technologies - Voice, images, and data with tele communications, electronics and computing · Satellite related technologies - Navigation (GPS, GLONASS, RDSS)
|
From page 44... ...
Manufacturers of navigation systems will provide support for maps from multiple map suppliers, opening up new markets for their systems. · Portable navigation systems should soon offer path finding and digital yellow pages to complement the portable electronic business card directories and daily planners that are now common.

My personal preferences on factors to use in prioritizing the plan are (in order of importance) : Air safety Safety at sea · Environmental concerns · Other positioning needs of government and industry · Positioning needs of scientific community My order of importance of proposed strategic goals: SG ~ Airport Surveying and Mapping SG 7 Mapping the Coastal Zone SG 12 NAVD 88 Implementation SG 10 GPS Leveling SG 13-Data Access SG 11 GPS Orbits SG 9 CORS SG 6 - Geodetic Research SG 2 Coordination of Federal Geodetic Activities SG 1-Transition to NSRS SG 3 Federal Base Network SG 4 ~ Cooperative Base Network SG 5 User Densification Network

Significant, overlapping trends In spatial data management related to spatial reference systems: · increasing need to integrate multiple data sets (vertical integration, horizontal integration, and integration of different formats as well as types of data) ; Example: local to national/global level; satellite imagery with conventional map data; local land records system development need for real time, static positioning information direct to users Example: cadastral surveys; personal location devices and anti-theft tracking devices · need for three dimensional and dynamic positioning capabilities Example: DTMs; monitoring systems; vehicle navigation · need to support development of national spatial data infrastructures Example: NRC report Examples of related issues for spatial data management: increasing use of GPS positioning access to data incompatibility of data being collected and captured: different datums; different accuracies (conflation programs)

54 FOR EM ON NOAA 'S NATIONAL SPATIAL REFERENCE SYSTEM · Quality, Quality, Quality how to achieve? This comes with motivation Motivation comes when well-chosen personnel are given adequate resources this is not the situation today TOM is not enough Some advice and interaction from the outside is required-grants program should be established, links with academic and research commun~ty enhanced · Futuristic outlook is very important There are too many outmoded concepts Draft Implementation Plan has the correct concepts scattered throughout, but it gets obscured by the "old" ideas
|
From page 55... ...
STRATEGIC GOALS 7 & 8 55 Whereas the NGS should well be the Government researchers and coordinators of Geodetic activities the private sector is well capable of performing coastal mapping as well as Airport surveying and mapping. · Take the example of the Army Corps of Engineers in developing supervisory and contract administration to facilitate and build a working relationship with private industry to provide the survey product.
