10 2018 Spring Acquisition Summary Stats 13 flight days Roughly 70 flight hours 16 mission (including re-flights) Approximately 62,000 exposures About 45 sensor hours Challenges Air Traffic, especially east part of 3 ortho area, very busy air space Weather at beginning and end of flight schedule Opportunities ATC helpful and understanding Dry winter, little snow cover Weather was generally cooperative, especially during 1 st two weeks of March 10

11 Click Interim Click to to Imagery edit Master - Quick title style Ortho style Services Interim data is being streamed already months earlier than in previous projects! The Quick Ortho methodology is meant to provide you with the earliest possible access to the 2018 imagery. You will likely see positional accuracy and aesthetic issues (all to be corrected in your final deliverable). Everyone has access to the highest resolution captured, because: Creating multiple services and restricting access would delay delivery; The services are temporary and will expire when final deliveries are made; QAQC will be better if everyone is looking at the best data; and It s an opportunity to show the quality of the 3-inch data to those that haven t yet paid in for that resolution (there s still time to buy-up!).

12 Click Interim Click to to Imagery edit Master - Quick title style Ortho style Services Two options for access: Geoserve and a WMTS Geoserve is a proprietary web interface developed by Sanborn that shows the imagery with other important contextual layers. This is what we will use in the fall for QAQC. The WMTS can be loaded in ArcGIS (be sure to Add WMTS Server instead of a WMS server). One layer in the service coming May 2018 Color-balance coming July 2018 Final WMTS (ortho, no seamlines) coming December 2018 Credentials were distributed via on 3/15/18.

13 Click to edit Master title style Click to edit Master title style BRIEF GEOSERVE TOUR

14 Click QAQC Click to to Procedure edit Master title style style Partners Use Geoserve to report aesthetic issues including: Seamlines, shadows, building lean, blur, haze, bridge distortion, etc. Assignments have already been accepted. Work will be done in the fall. Training and criteria will be provided. Who is responsible for DAT this year? We are! Why? To save money and to evaluate firsthand the cost/benefit of doing it ourselves DRCOG Use past project GCPs to evaluate positional accuracy.

15 Click Partner Click to to GCPs edit Master title style style Did you lay out panels for the spring flights? Will you lay out panels for the summer flights? If yes, please: Send to DRCOG in case we need additional points for DAT. Reference these guidelines.

16 Click Aesthetics Click to to edit Survey Master Results title style style Conducted in February 23 respondents Focused on contrast, since we determined color and brightness preference during DRAPP The vote was to increase contrast for all resolutions (between 25% for urban 3inch and 45% in rural 12inch when compared to 2016).

17 Click Orders Click to to edit Master title style style No SID this year because a bug in the LizardTech software is keeping us from generating multi-resolution SIDs. We still offer a compressed format (JPG2000). Orders have already been provided to Sanborn so they can plan for packaging/shipping. If you didn t respond to the order , I used your 2016 order as a guide. You ll get one more opportunity to review your order (September 2018) to make any last minute changes. The full area might be delivered later after everything else.

18 Click Supplemental Click to to edit Master Imagery title style style Partners received quotes in mid-june 2017 that compared: Resolution Flight timing Estimated delivery dates Cost Coverage Positional accuracy QAQC Procedures Deliverables Trial availability Access to historical imagery Licensing Support for derivatives (e.g. planimetrics) RFP in January 2018 for supplemental streaming services. Google (via Sanborn) won the evaluation, but the consortium voted (96%) to not pursue that solution. Google had the most interest. Not enough interest in any option to fund it.

19 Click Supplemental Click to to edit Master Imagery title style style What have I learned from these exercises? Past off-year imagery (i.e. 2017) is not enticing. Partners want fast turnaround time on current imagery. The supplemental options available to us are lacking, either: Not the right time period of capture Slow turnaround time License terms that don t work for us Partners needs for supplemental imagery are more varied than for the primary imagery (DRAPP) so we are having a harder time determining a suitable solution. Discussion questions Is the DRAPP 2018 interim imagery WMTS satisfying the need for quick turnaround on current imagery? Does our project still need a supplemental source? If so, what kind?

22 Click Regional Click to to edit Planimetrics Master title Project style style 2018 What: A regional project to acquire building roofprints, sidewalk centerlines, parking lots and more! When: Delineations occur in 2019, project planning happening now. Why: To update previously collected data on the built environment and leverage our investment in imagery How: With contributions from users like you!

23 Click Regional Click to to edit Planimetrics Master title Project style style 2018 What makes this data valuable? Very detailed (1:100 map scale) Manually drawn (no automated methods = no errors of commission) Based on DRAPP imagery (high resolution and strict positional accuracy standards) Current (updated every two years following completion of DRAPP) How is the data being used? Public agencies Water modeling emergency response planning floodplain analysis asset management bike/ped master planning scenario planning - visualizing reality Private companies App to help the visually impaired navigate as pedestrians selling attribution that attaches to our geometries consulting firms doing better work for local clients like cities and counties site selection apps Researchers Evaluating intersection safety estimating energy savings

24 Click Regional Click to to edit Planimetrics Master title Project style style 2018 Goal gain more partners so that this project can become routine just like DRAPP and: Continually provide current high-quality data at a small fraction of the cost of ad hoc projects; Consistently generate standardized built environment layers for the region; Drive research, innovation, and entrepreneurship by sharing our data with our communities.
