The Earthnet Data Assessment Project (EDAP+) continues the work of its predecessor (EDAP 2018 – 2021) and is responsible for assessingthe quality and suitability of candidate missions being considered for ESA's Earthnet Programme as Third Party Missions (TPM). Early data assessments are publicly disclosed to the community ([RD-1]). Based on its own infrastructure ([RD-2]), Telespazio is responsible for theanalysis of Very High Resolution optical data, including assessment on geometry, radiometry and image quality ([RD-3]). In most cases, inherited from design tradeoffs in the new space domain, the geometry remains a critical aspect. Main outcomes fromvarious workshops ([RD-4]) point out the needs regarding openly available reference data and openly available data assessmentprocessing tools. In this context, a new tool dedicated to geometric assessment has been created:Kanade Lucas Tomassi (KLT) based Algorithm for Registration of Images from Observing System' (KARIOS) The main driver of KARIOS initiative is to support operator for following quality control assessments• Multi temporal geolocation to evaluate the geolocation stability of the mission,• Absolute geolocation to evaluate the geolocation accuracy of an input image gridagainst a well-controlled absolute reference image,.• Band-to band registration to evaluate co-registration between image band grids, allwithin a same product
