A system and method for improving the resolution and accuracy of avionics databases with limited impact on the size of the database includes identifying tiles including runway approaches and incorporates higher resolution tiles for those regions. The system may also identify tiles including high terrain variability. Those regions may also include higher resolution tiles. The system may identify multiple tiles that each define the same elevation and / or terrain variability. Those tiles may be consolidated into a single lower resolution tile. Aircraft may record elevations via onboard sensors. Multiple sensor samples may be combined and applied to an existing database to constrain the database accuracy.
