1 Obstruction Surveys and Airport Airspace Analysis Bob Vander MeerDirector of Aviation Programs
2 Obstruction Surveys and Airport Airspace Analysis This presentation will detail the project considerations learned through producing airspace analysis under the new AC150/ a, 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
3 Multiple Parties are Needed to Make Projects a Success Airport SponsorFAA/NGSAirport ConsultantsProgram ManagersVarious Subconsultants
4 Planning to Assure Appropriate Mapping LPV ApproachUpdate to Master PlanUpdate toward new eALPBase Mapping for New ConstructionObstruction Survey for Runway ExtensionTable 2-1 in AC18B, “Survey Requirements Matrix” will help define required information
6 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 airportAll the items affect the project design.
7 Planning to Ensure the Airports Needs are Met Now & for Future Purposes Sponsors must consider project requirements:Minimum of 1’ pixel resolution quality requiredHigher accuracy is typically necessaryDoes your project require topography?1’ Contours2’ ContoursDoes your project need engineering quality planimetric mapping?Imagery limits for obstruction analysis may not cover other project parametersThe answers to these questions impact the whole project
8 Impacts of Design The Design Criteria May Impact: Multiple Flights Leaf on for obstructionsPossibly leaf off for specific mapping needsGround SurveyHigh accuracy data requires significantly more survey control pointsDetailed runway profilesDetailed planimetrics may require survey field checksOrthophotos1’ color orthophotos will be required for the obstruction surfaces.5’ or .25’ orthos may be generated for airport propertyAll decisions will have an impact on cost and schedule
9 What is the Process? Develop a Project Scope Work with consultants to ensure both the AIRPORTS, FAA, & NGS’s needs are metSponsor (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 PlansThe plans MUST support the SOWField Work to be CompletedAcquire aerial imageryAcquire field surveySponsor to provide existing data that maybe requiredSubmit Scanned Imagery & Survey to NGS for ReviewGenerate Final Mapping & Submit to FAA & NGS for ReviewMapping & attribution of required features
10 Overview of FAA’s Website https://Airports-GIS.faa.gov/
11 Data Upload Process Airport Sponsor or Consultant Roles Create Log In for Airport Project on the FAA GIS/TPSS SystemsAllows for Project Tracking by FAA, Sponsor & ConsultantsAll Data must be uploaded through SystemData remains on system to allow future use of existing dataFederal AviationAdministrationhttps://airports-gis.faa.gov/airportsgis/
13 What is the Purpose of SOW & Plans? The Statement of Work Sets Up the Plot of the StorySOW explains WHAT you are going to doFAA is requiring more detail to be added to SOWThe Plans Expand on the “What” and Explain the “How”Explains in further detail what you are going to doExplains your methodologies in detailAdvisory Circular RequirementsWhat are the AC requirements for your particular project?How do your methodologies ensure required accuracies?Together, Project Plans Tell the Story From Beginning to EndProvides background and purposeProvides a timelineProvides a work planDefends methodologies and ties to Advisory Circulars
14 Overview of PlansAC-150/ A - Geodetic Control PlanRequired when establishing new PACS/SACSDetails methodology for establishing PACS/SACSAC-150/ B – Imagery PlanSubmission/Approval required before acquisitionAcquisition report if deviating from imagery planDetails methodology for imagery acquisition and useAC-150/ B - Survey/Quality Control PlanRequired for any survey project initiated thru AGISSubmission/Approval required before project commencementDetails methodology for data acquisition and quality controlOutlines GIS data attribution and features collectedAll Plans must be submitted to the FAA through the FAA GIS/TPSS Website
15 Sample Project Process Sample process from the point that a Statement of Work has been uploaded, through project uploadWhat happens & when?How long will the process take?
16 Submission of Statement of Work Provides Project ScopeOutlines Project DeliverablesProject Plans OverviewMust Submit SOW to the FAA through the FAA AGIS WebsiteProject Time FramesCreation: weeksFAA Approval: 2-4 weeks (FAA workload dependant)
17 FAA’s AC 150/5300-16A Requirements (Survey Plan) Establishment of Geodetic Control and Submission to the National Geodetic SurveyDevelop Project Survey Plan, upload to FAA’s GISDecisions on use of PAC’s/SAC’s or Temporary ControlFinal Survey Deliverables and Report to NGSProject Time FramesCreation: weeksNGS Approval: Weeks(NGS workload dependent)
18 FAA’s AC 150/5300-17B Requirements (Imagery Plan) Airport Imagery Acquisition and Submission to the National Geodetic SurveyVertically or Non Vertically Guided SurfacesImagery purposeFlight lines, exposure counts, control point layout, photo scales, etc.Overview of processing and quality assurance proceduresProject Time FramesCreation: weeksNGS Approval: Weeks

21 FAA’s AC 150/5300-18B Data Submission Airport Obstruction Survey Completion and Submission to FAA/NGSConsultant must provide the following:Complete Photogrammetric MappingComplete Field Survey including Runway Profiles & Nav Aid SurveysComplete Field Verification of all survey dataSubmit completed survey to FAA’s GIS Website for ApprovalProject Time FramesPhotogrammetric Mapping…………………. 2-4 weeksField Survey and Obstruction Verification… 2 weeksFinal database formatting andSubmission of Final Survey………………….. 2 weeksNGS Approval: Days (NGS workload dependant)

23 Lessons Learned Project Scope & SOW Plans Submission Division of Work This is a project between, FAA, NGS, sponsor & consultantsCommunication is keyScope of Work should provide specific project goalsFAA is requesting more & more detail in both the SOW and the project plansProject plans are your road map to successSooner is better than laterGet your imagery plans in early for fall flight seasonPlans could take several months to get approvedPlan aheadClear division of work between consultants is essentialTranslation and validation of existing data if appropriateAttribution of data is a huge cost, who is doing it?Who will assure data is properly formatted for upload?
