Find survey mistakes
before they become
site problems.
CheckMarkup turns survey reports and field files into clear, visual, traceable QA evidence: upload the files, check the data, mark issues on the report or map, and decide the right office or field action before delivery.
CheckMarkup is a QA assistance and markup tool. It does not certify survey work, replace a qualified surveyor, or automatically correct raw survey data.
Designed around the tools surveyors already use
