Description

As the agency reported it.

Purpose
The purpose of this award is to assist hamilton county in completing the final preparation, delivery, and acceptance of its new 2024 QL1 lidar dataset under USGS 3DEP program requirements. This project will ensure that the countys latest high-resolution elevation data formally replaces the current 2016 QL2 data, becomes part of the USGS 3DEP holdings, and supports indianas long-term participation in the USGS 3DEP and 3DHP initiatives.
Activities
Hamilton county will coordinate with USGS to submit all required QL1 lidar deliverables, including classified point clouds, hydro-flattened bare-earth dems, breaklines, swath separation imagery, metadata, QA QC documentation including vertical accuracy assessment. Activities will also include responding to any USGS QA QC callouts, performing required adjustments or corrections if necessary, and finalizing all data products for formal acceptance. Contracted technical support from dewberry engineers will assist in any redelivery or revision activities.deliverables and expected outcomes: deliverables include the complete submission of:classified QL1 lidar point clouds (LAS format) (tested point density: 27.44 ppsm)hydro-flattened bare-earth digital elevation models (dems)breakline and hydrologic enforcement featuresswath separation imageryfgdc-compliant metadataqa QC summary reports documenting independent review and compliance verificationthe expected outcome is full acceptance of hamilton countys QL1 lidar dataset into the USGS 3DEP program, ensuring the data is publicly available through the national map. The data will provide a modern elevation base for future EDH development aligned with USGS 3DHP specifications.
Intended beneficiaries
The intended beneficiaries of this project include hamilton county government agencies, indiana state and local agencies, indianas nrcs office, the USGS, other federal mapping and emergency management programs, and the general public. These data will improve flood risk mapping, infrastructure planning, environmental resource management, and statewide hydrography modernization efforts.
