Historical Areas of Concern Mapping and Sampling Design
|Representative Project:||Historical Areas of Concern Mapping and Sampling Design|
|Services:||Database Development / Spatial Analysis – Overlay Analysis|
Padre acquires and geo-references historical aerial imagery spanning decades. Each image is reviewed to create a spatial database of areas of potential concern (AOPCs). Often features seen in historical images no longer exist and are not apparent during a field visit. Mapping and cataloguing attributes of historical features is an important step in identifying areas to sample and focus remediation efforts. Mapped AOPCs act as a guide for sampling design. Padre leverages high accuracy GPS technology to navigate to proposed sample locations and collect ‘as-built’ sampling locations. Sampling locations and their analytical results are fed back into the project spatial database. The bolstered spatial database of AOPCs, sample locations and results are then used to create maps and cross-sections to plan for remediation design.
