Scope of Work/Phases > Initiation > Ground control survey

> Digital aerial photography and airborne control survey > Aerotriangulation > Interim 3-band orthophotography > DEM Review/Update – new DSM/DEM generation as needed > Final 4-band digital orthophotography and metadata > Covering 11-county, ~7000 sq. mi. Denver, CO region

All work performed in-house from/at Kucera headquarters office (Willoughby, OH)

Regular, scheduled communication/status reporting

Use of proven, latest generation technologies and procedures

Thorough batch and manual QC review/edit process

Strive for improvement upon previous years' orthos

Kucera Approach - General

Kickoff Meeting/Conference

> Introduce points of contact

> Review project phases and deliverables

> Review project procedures and technologies

> Administrative/contract details

> Past contract review – procedures and deliverables

Project Procedure Plan

> Flight/control plan + tile layout

> Completion schedule + milestones

> Deliverable listing/transmittal procedures

> Equipment listing/calibrations

> Quality control criteria and procedures

Source Data Review – Received January 2012

> Project area boundaries and tile scheme

> DEM and ortho from 2008 + 2010 projects

> Ground control records

> Building points and bridge centroids

Project Initiation / Source Data

Point marking and field identification/referencing> Semi-permanent, e.g., - Pk nail, rebar, chiseled mark> Photos + description sheets

Control report - hardcopy + digital

> Procedure summary> Control listing > Network diagram

Control Survey / Georeferencing (Con't)

Aerial Photography Acquisition Time Frame

> Areas 1, 2, 4 - March 15 - April 15, 2012 (~ 60 flight hrs.)> Area 3 - June 2012 - after DRCOG authorization (~ 12 flight hrs.)

Capture Technologies> Piper Navajo Chieftain twin-engine aircraft, one w/ 2 sensor port> Leica ADS40/SH51 4-band, large format, pushbroom/strip image capture digital aerial cameras> Leica IPAS AGPS/IMU

Conditions> No significant clouds/cloud shadows, snow, flooding, leaves (Areas 1,2,4) > Minimum 30 degree sun height, 40 degrees over downtown Denver

Base of Flight Operations> Centennial Airport - Arapahoe County> Aircraft available for viewing during non-acquisition hours

Flight Plan> Areas 1 and 4 - 4700' above ground - 0.5' image capture> Areas 2 and 3 - 9400' above ground - 1' image capture> N-S Flight lines - full tile coverage> 30% side image overlap, 60-80% for reduced lean/”near-true” ortho areas

Leica ADS40 Digital Camera Technology

Kucera experience – 6 years, >200 counties/cities + 1 state (OR) - ~210,000 sq miles

Two committed systems + 1 backup available

Upgraded 51 series sensor heads (SH51)> Full alignment of color and infrared imagery> Improved image quality – shadow + highlight detail> Proper use of integration time for optimal image quality

Advantages of strip image capture> Reduced overall feature lean> Reduced image “stitching” / mosaicing required> Supports expedited preliminary ortho image delivery

> Varied stereo views/exaggerations support efficient DSM autocorrelation > Not susceptible to multiple camera-system anomalies (e.g., image “fringing”)

■ Inherent characteristic – elongation of moving vehicles in line of flight> Generally occurs only for vehicle speeds >35 mph> Can reduce effect using different image views (forward, nadir, aft)

Building No Lean Reduction

Reduced Mosaicing

Interim Orthophotography Time Frame

> Areas 1, 2, 4 - April 2012 delivery> Area 3 - June 2012 delivery

Production Technologies/Procedures> Leica XPro/ORIMA> Georeferencing to AGPS, ground control, existing DEM> Accuracy - ASP Class 2, as supported by existing DEM

Ortho Image Delivery> 3-band color> uncompressed GeoTIFF format> include digital flight index

DEM Preparation

Time Frame – May - August 2012 delivery

Production technologies/procedures> DSM Generation - Leica DSM

> Change Detection - Global Mapper > DEM Classification - TerraSolid Terramodeler

> Breaklines as needed- BAE Socet Set stereoplotters> Test rectification w/ source DEM> Determine areas of change> Update and/or replace as needed

Deliverable> New/updated DEM in specified format/datum (e.g., shapefile)> Optional DSM w/ or w/o image draping

Change Detection

Final Orthophotography Time Frame

> Pilot Areas 1, 2, 3 – June 2012> Pilot Area 3 - July 2012> Full Areas 1-4 - July - October 2012

Production technologies> Image rectification - Leica XPro> Image mosaicing/tiling - Inpho OrthoVista> Image edit - Adobe Photoshop> Datum conversion - Global Mapper

General process> Initial rectification + QC/geometric accuracy check

> Image mosaicing/seam line placement> Radiometric/color/tone adjustment/balancing> PLS tile extraction> Manual tile QC review/edit> Datum conversion/reprojection> Final uncompressed QC review + delivery> Compressed QC review + delivery

QC review process matching DRCOG DAT criteria> Positional accuracy> Feature representation geometric integrity> Image radiometry/resolution/detail visibility> Image coverage, organization, formats, metadata

Orthophoto Deliverables

Datums/Projections> NAD83/HARN CO Central Zone State Plane> NAD83 Pre-HARN CO Central Zone State Plane> NAD83/HARN CO North Zone State Plane> NAD83 Pre-HARN CO North Zone State Plane> UTM Zone 13 North, NAD83, meters

Uncompressed imagery> 4-band> PLS tiles> GeoTIF or TIF/TFW format

Compressed imagery> 4-band > PLS tiles>10:1 JPEG2000 w/ world file>10:1 JPEG2000 GeoTIFF>10:1 SID Gen 3 w/SDW

Associated data> FGDC-compliant XML metadata by tile> Mosaic seam line files -shapefile

Special Requirements - “Reduced Lean/Near True Orthophotography> Downtown Denver> Denver Tech Center> Denver Medical Campus
