Texas Strategic Mapping Program Lidar Initiatives June 7, 2017 Houston-Galveston Advisory Council Monthly Geographic Data Workgroup Meeting Houston, Texas
StratMap Program • Maintain authoritative, trusted state geospatial layers based on national standards. Acquire new geospatial data Update existing geospatial data • Define a common mapping standard to ensure consistent, high quality data for the State of Texas and the public. • Attract partnerships to increase the purchasing power of public funds.
StratMap Contract Initiated/held by Department of Information Resources Administered by TWDB-TNRIS • Pool resources • Lower cost per entity • Higher quality service • Save time – no individual procurements Established 2016 Expires 2020

StratMap Contract How it works 1. Project initiation 2. Compile Statement of Work (SOW) 3. Release Solicitation w/SOW to StratMap Vendor Pool 4. Evaluate proposal responses 5. Purchase Order sent to winning vendor(s) from each partner referencing StratMap Contract(s) 6. Ongoing project management from TNRIS or on your own 7. Quality Assurance and Quality Control (QA/QC) 8. Data review and acceptance
Lidar Acquisitions 2016-2017 StratMap Lidar Acquisitions • Central and East Texas Projects were awarded grants from the USGS 3-D Elevation Program ( 3DEP ) totaling almost $600, 000.00. • Central and East Texas Projects were acquired by Fugro with third-party QA/QC by AECOM Technical Services. Expected Delivery October 2017 and January 2018 . • Coastal Lidar Project was acquired by Sanborn with third- party QA/QC by AECOM Technical Services. Expected delivery September 2017 .
Lidar Acquisitions 2017-2018 Lidar Acquisition • TWDB is currently plans to commit $500,000.00 for a coastal acquisition this winter to replace the remainder of 2006 FEMA data. • StratMap will pursue 3DEP funding for eligible areas. • The coastal region is almost entirely eligible and has been identified as a priority areas for federal 3DEP partners.
Lidar Acquisitions • H-GAC would directly benefit as TWDB AOI is adjacent to and includes portions of H- GAC’s area. • Total acquisition of ~9,400 square miles to recover non QL2 data in H-GAC area. • TWDB is pursuing a coastal acquisition to replace the FEMA 2006 collection. • TWDB can potentially cover ~3,600 square miles within the H-GAC Area. • Potential USGS 3DEP funding of 30% would cover ~2,800 square miles. • Estimated cost per square mile: $125-$175. A partnership with TWDB to recapture non QL2 data for the H- GAC area with the addition of 3DEP funding has the potential to carry discount of ~68% . In this situation H-GAC would only pay for around 3,000 of the 9,400 square miles for that acquisition.

Schedule Timeline December- August September October November February • SOW to DIR • Evaluate proposals • 3DEP Grant • 3DEP Award • Acquisition Proposal • Post SOW • Award • Purchase orders to vendor from Partners • Beginning of August is the cut off for SOW participation and ability to maximize cost share. Partners in SOW will gain additional cost share from 3DEP funding, if awarded. • November will be last chance to participate at proposed cost by vendor. Late additions will not be able to capitalize on 3DEP funding for their areas. • Acquisition will begin in December when leaf off conditions occur.

Lidar Updates • Currently 60,000 square miles of new lidar in production from StratMap and FEMA. • Data should be delivered this winter, and will become available via TNRIS.org. • Two FEMA acquisitions have been postponed until winter 2017-2018. • Status of projects can be seen on the TNRIS lidar status map.
