Today was a good day for all aspects of the DeaconEye project. We had 2 missions for the day, to collect imagery of all of Reynolda meadow for mosaicing and to do a thermal imagery trial run to assess the ability of DeaconEye to collect good thermal imagery. The day really started yesterday, with us making 4 test flights (~1 hour flight time) to ensure that everything was in good working order and we would have no surprises today. We worked out the last of the kinks related to the issues we had with magnet errors and poor telemetry connectivity and ended yesterday feeling confident about the state of everything.
Today we started out by collecting the RGB imagery of the meadow. We imaged the entire meadow in 3 flights (if you don't count one aborted flight, more on that later) using 3 sets of batteries. We made the first 2 flights on the Thunderpower 6600 pair and made the next 2 on Hyperion 5000 pairs. We elected to change batteries after we aborted a flight a couple minutes in to ensure that we did not push the envelope.

Big Deac
Big Deac is up, running, and fully operational. System specifications are as follows:
- Dual Intel Xeon E5-2620 CPUs (6 cores each at 2.0 GHz, 24 total virtual cores)
- 64 GB RDIMM ECC DDR3 RAM
- AMD Radeon HD 7970 GPU (32 OpenCL cores, 3 GB DDR3 RAM)
- SuperMicro X9-DAI motherboard (4 PCI-E x16 slots, 16 DIMM slots, 10 SATA ports)
- 2X 2TB Western Digital Black HDDs (RAID 1, for long-term storage)
- 128 GB Samsung 840 Pro Series SSD (Soon to be 2 in RAID 0, for working with data)
As the specs above might betray, Big Deac is a beast and has laughed at most things we have thrown at it so far. While using Photoscan we have now found that we are software limited and no longer hardware limited. We are capable of processing image sets of up to 1000 uncompressed TIFFs on the highest quality settings,
