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.

How it works
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 Fugrowith 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.
2016-2017 StratMap Lidar Acquisitions
Lidar Acquisitions
• 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.
2017-2018 Lidar Acquisition
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.

August
•SOW to DIR•Post SOW
• 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.
