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.

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 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. 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.

Lidar Specifications

TNRIS USGS QL2

0.5m NPS/4 ppsm 0.71m NPS/ 2 ppsm RMSEz 10cm (non-vegetated) RMSEz 10cm (non-vegetated) Classifications: 1,2,3,4,5,6,7,9,10,13,14 Classifications: 1,2,7,9,10,17,18

The Texas Lidar Specification is modeled very closely to the USGS Lidar Specification version 1.2 and the ASPRS Positional Accuracy Standards for Digital Geospatial Data

Vendor Delivered Products

• LAS Point Cloud
• Hydro-flattened DEM
• Hydro-breaklines
• File level metadata
• 3rd party QAQC Report

TNRIS Derivative Datasets

• 2ft and 5ft cartographic contours
• Building footprints

All data and derivative datasets will be publicly available for download at TNRIS.org.

Schedule

December- February

• Acquisition

November

• 3DEP Award
• Purchase orders to

vendor from Partners

October

• 3DEP Grant

Proposal

September

• Evaluate proposals
• Award

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.
