2015 NAIP Post-Mortem
The 2015 NAIP Post-Mortem meeting was held at APFO in Salt Lake City, UT on December 1, 2015.
Kent Williams (APFO) started the meeting with an overall welcome and quick introductions.
Bridget Barlow (APFO) gave a summary of the 2015 NAIP program. She discussed the task order awards and quantities given to the three prime contractors. Imagery acquisition during 2015 was greatly hindered due to forest fire smoke and significant cloud coverage. The smoke and poor weather prevented the acquisition of 834 Montana DOQQs before the first major snow fall in late November. APFO is reviewing possibly collecting the missing 834 DOQQs in 2016.
Each of the three NAIP prime contractors (Jodi Delorme for North West, Peter Briere for Quantum Spatial, and Tim Bohn for Surdex) gave briefings on their performance and lessons learned from the 2015 season. A common topic between the three briefings was the impact to imagery acquisition due to forest fires and unseasonably wet weather this past summer. Surdex included a quick discussion on the Wyoming stereo and point cloud dataset buy-up. The group discussed if the perennial snow definition could be moved to an earlier date from the current August 1 date (meaning at what acquisition date snow on the ground would be considered perennial and most likely not melt). Also discussed was the usage of the Early Access Web service (EAWS) and how the usage should significantly increase once FSA incorporates the service into their enterprise applications. The contractors offered to increase public awareness of the web service by writing articles for trade magazines or papers for conferences.
Joan Biediger (APFO) briefly discussed the current status of Super-resolution imagery test. Joan is currently conducting a blink test (similar to the “Pepsi Challenge”) among the native collection and the four additional collections. The purpose of the test is to determine if, and at what multiplier, could the ADS-100 high resolution mode be used on NAIP.
John Mootz (APFO) discussed the increasing airspace clearance denial over military installations and the possible impacts of collecting at a higher resolution. APFO is in contact with the DoD and will continue to work with them on trying to resolve the issues. John Welter (North West) did state that the XPro software used to process the ADS-100 imagery does have a “black out” feature that can blank the original raw imagery with 0,0,0 if we have a shapefile of sensitive areas.
An open discussion on several key topics followed John’s conversation.
- The 2015 task orders incorporated the EAWS price into the DOQQ price preventing the contractors from invoicing for the cost of the service which occurs weeks before the acquisition performance payment. APFO will modified the contract and/or 2016 task order to allow a 2% performance based payment once the EAWS has been turned on.
- For all practical purposes, the coarsest resolution the ADS-100 sensor can acquire is 80 cm. The dialogue centered on the key question of why we are asking for a 1-meter product if we get a better resolution image with only a minimal increase in production cost. A long conversation occurred on whether the specifications should be changed to a fixed resolution (such as 80cm) or ask for the native resolution. Since the native resolution would vary based on several operational factors, the resulting inconsistent resolution could potentially cause more problems than possible resolution benefits.
- APFO asked the contractors if increasing the horizontal accuracy specification from the current ±6-meter requirement would cause any risk or cost impacts. All three contractors stated that they are currently measuring less than ±3-meter errors, a slight tightening of the specification would not have an impact.
Bridget Barlow gave the final briefing on the 2016 NAIP Plans. APFO is expecting to award 22 states for the 2016 acquisition season – the twenty one states not flown in 2015 plus North Dakota. At this time, no ½-meter buy-up partners have been identified for 2016.
- What was the maximum concurrent users of EAWS during the 2015 season (assigned to: North West, Quantum, and Surdex; due date: Dec 31, 2015)
- Determine if the perennial snow date of Aug 1 can be moved up earlier without impacting (assigned to: Everett; due date: Dec 31, 2015)
- Review NAIP coverage to determine in some areas, such as no CLUs or are at a higher alt, can have their seasons adjusted to minimize season extensions (assigned to: Brian V.; due date: Feb 28, 2016)
- Draft initial specifications for stereo/point cloud datasets for 2106 season (assigned to: Surdex; due date: Dec 31, 2015)
