I found, while working on a terrain following/avoidance system for some of the aircraft I've done, that the Nasal geo.elevation(<lat>, <lon>) function will return the height of buildings or other structures e.g. bridges located at that <lat>,<lon>. There are not any in-built FG scanning schemes/mechanisms though, so you'll have to design and implement one in Nasal to fit your needs. Have a look at the cvs BAC-TSR2 TFA nasal stuff to see the simple look-ahead scanning schemes I've done. Both of the schemes I've used just perform a single track look-ahead scan, compensated for yaw but not for turning flight (yet).
