advantage of [*Mega-Archive*]{} for science other than NEAs. In 2017 we introduced MASFO tool to search the [*Mega-Archive for Fixed Objects*]{}. In 2018 we implemented the MASDS tool for [*Mega-Archive Search for Double Stars*]{}. To specify exactly the exact CCD of major mosaic cameras include in the [*Mega-Archive*]{}, in 2016 and 2018 we built the graphical [*FindCCD*]{} and [*FindCCD for Fixed Objects*]{} to overlay the moving or fixed targets over seven mosaic cameras, plotting also the uncertainty ellipse for poorly observed NEAs. In the near future we plan to grow the [*Mega-Archive*]{} and improve [*Mega-Precovery*]{} and other related data mining tools.\
We have entered already in the big data epoch, where present and future surveys will provide huge amount of imaging data valuable for data mining and time-domain astronomy. In this sense, we recommend to the IAU, specifically Division B (Facilities, Technologies and Data Science) and Commissions B2 (Data and Documentation) and B3 (Astroinformatics and Astrostatistics) to adopt a common format and recommend to all astronomical observatories to use it for indexing and storing their science images, and make them available for programmable queries.\
On a cosmic scale, NEAs pose real threat to mankind, and there are cases when faint
