Texas Imagery Participation Update - Gayla Mullins

Google provided notification of current/upcoming quality issues o “Thin Line” issue: Thin lines have so far appeared every 100 yards in 8 blocks flown from 8/17 to January 2018 o Quality control process is ongoing, more blocks flown during this period may present issue, Google will notify if found o “Thin Line” issue will persist until next fly-over of affected areas Gayla expressed concern around consistency and currency of data o Some blocks flown twice in same year, some not flown at all o Some blocks not refreshed since 2014, asked Google to prioritize these Group discussed currency requirements o Entire state must be refreshed at least every 3 years o Concurred with need for priority on blocks last flown in 2014 o Suggested using older (within 3 years) images rather than newer, quality-reduced images until next fly-over o Stated as long as spatial accuracy is not affected, newer is better o Concluded newer images will be used, with access to older on request (Unknown) requested Brownsville be given extra priority due to ongoing project New customers continuing to sign up about 1/mo, most recently UT

Google Cloud Platform Storage - Jenn Sylvester

Continuing investigation indicates any hybrid solution will incur additional cost, suggestion is to choose one storage line per layer Based on historical usage data, Statewide layer is a prime candidate for conversion to cold-storage o This comprises the bulk of current storage, ~24TB, and will produce the greatest immediate savings o Conversion will take ~3 days, existing layer will be available until completion o Approval given to proceed with conversion, contingent on successful test run Discussion opened regarding serving LIDAR rather than storing as image layer, tabled until later date.
