Quality Control
Digital Orthophotograhy Project
Asunción, Paraguay

Woolpert International provided quality control and quality assurance services to the Ministerio de Hacienda (Servico Nacioinal de Catastro) for the production of digital orthophoto quad maps for the nation of Paraguay.  We reviewed the existing ground control network, aerial triangulation, planimetric and topographic maps, and digital orthophotos to ensure that these items complied with project technical specifications.  Work included:

• On-site review of monument conditions and placement

• Verification of the cartographic production of map sheets with feature annotations and topographic content
