NLT provided an intermediate GIS specialist onsite at the Aberdeen Proving Grounds in Aberdeen, Maryland. NLT’s GIS specialist performed quality assurance and quality control on Operational Range Inventory Sustainment (ORIS) data concerning Army Training Lands. That process included identifying errors in coordinate resolution and drafting revised ORIS output to Army installations and agencies. Quality verification included visual inspection, automated checks using the Production Line Tool Set (PLTS), topology authentication, attribution validation, and other custom quality control tools.NLT also provided data composition and map production, updated Army 101 course materials with appropriate maps and figures highlighting GIS capabilities, and created a custom tool using ArcGIS Model Builder to verify the spatial accuracy of source data against the final product. ArcGIS Model Builder and other GIS tools were used on the project.
