Obstruction Surveys and Airport Airspace Analysis

Obstruction Surveys and Airport Airspace Analysis

This presentation will detail the project considerations learned through producing airspace analysis under the new AC150/5300-16a, 17b & 18b Airport GIS requirements.

Project Scoping Considerations discussed will include:

What detail of mapping is required for your projectThe use of temporary vs. permanent geodetic controlImagery resolution (flying heights)Data collection, analysis, submittal and acceptanceGIS Data Attribution, Identify Features and AttributesTimeline from NTP to NGS data acceptanceChallenges and lessons learned

Multiple Parties are Needed to Make Projects a Success

Table 2-1 in AC18B, “Survey Requirements Matrix” will help define required information

Planning to Assure Appropriate Mapping

Planning to Assure Final Deliverables

What are the airports current needs?

What are the airports future needs? 5 year? 10 year?

What are the FAA’s minimum expectations?

What are the final deliverables for the consultant & the airport

All the items affect the project design.

Planning to Ensure the Airports Needs are Met Now & for Future

Purposes Sponsors must consider project requirements:

Minimum of 1’ pixel resolution quality required Higher accuracy is typically necessary Does your project require topography?

1’ Contours2’ Contours

Does your project need engineering quality planimetric mapping? Imagery limits for obstruction analysis may not cover other project

parameters

The answers to these questions impact the whole project

Impacts of Design

The Design Criteria May Impact: Multiple Flights

Leaf on for obstructionsPossibly leaf off for specific mapping needs

Ground SurveyHigh accuracy data requires significantly more survey control pointsDetailed runway profilesDetailed planimetrics may require survey field checks

Orthophotos1’ color orthophotos will be required for the obstruction surfaces .5’ or .25’ orthos may be generated for airport property

All decisions will have an impact on cost and schedule

Develop a Project Scope Work with consultants to ensure both the AIRPORTS, FAA, & NGS’s needs are met

Sponsor (Airport) Must Create a Project on the AGIS WebsiteConsultant Must Submit a Statement of Work (SOW)

The language in the SOW must support the project scope submitted by sponsorConsultant Must Submit the 3 Plans

The plans MUST support the SOWField Work to be Completed

Acquire aerial imagery Acquire field survey Sponsor to provide existing data that maybe required

Submit Scanned Imagery & Survey to NGS for ReviewGenerate Final Mapping & Submit to FAA & NGS for Review

Mapping & attribution of required features

What is the Process?

https://Airports-GIS.faa.gov/Overview of FAA’s Website

Data Upload Process Airport Sponsor or Consultant

Roles Create Log In for Airport Project

on the FAA GIS/TPSS Systems Allows for Project Tracking by

FAA, Sponsor & Consultants All Data must be uploaded

through System Data remains on system to allow

future use of existing data

Federal AviationAdministration

https://airports-gis.faa.gov/airportsgis/

Airport GIS Website – Project Portal

The Statement of Work Sets Up the Plot of the Story SOW explains WHAT you are going to do FAA is requiring more detail to be added to SOW

The Plans Expand on the “What” and Explain the “How” Explains in further detail what you are going to do Explains your methodologies in detail

Advisory Circular Requirements What are the AC requirements for your particular project? How do your methodologies ensure required accuracies?

Together, Project Plans Tell the Story From Beginning to End Provides background and purpose Provides a timeline Provides a work plan Defends methodologies and ties to Advisory Circulars

What is the Purpose of SOW & Plans?

AC-150/5300-16A - Geodetic Control Plan Required when establishing new PACS/SACS Details methodology for establishing PACS/SACS

AC-150/5300-17B – Imagery Plan Submission/Approval required before acquisition Acquisition report if deviating from imagery plan Details methodology for imagery acquisition and use

AC-150/5300-18B - Survey/Quality Control Plan Required for any survey project initiated thru AGIS Submission/Approval required before project commencement Details methodology for data acquisition and quality control Outlines GIS data attribution and features collected

All Plans must be submitted to the FAA through the FAA GIS/TPSS Website

Project Scope & SOW

This is a project between, FAA, NGS, sponsor & consultants

Communication is key Scope of Work should

provide specific project goals

FAA is requesting more & more detail in both the SOW and the project plans

Project plans are your road map to success

Plans Submission

Sooner is better than later

Get your imagery plans in early for fall flight season

Plans could take several months to get approved

Plan ahead

Division of Work

Clear division of work between consultants is essential

Translation and validation of existing data if appropriate

Attribution of data is a huge cost, who is doing it?

Who will assure data is properly formatted for upload?
