Although aviation photogrammetry mapping efficiency is very high, but the mapping precision co., LTD. So, there must be amount of photogrammetric observations to participate in joint area network adjustment, in order to improve the accuracy of photogrammetric. As control point measurement tasks are not independent existence, must be better, for the purpose of improving the precision of photogrammetric combining with the photogrammetry technology requirements for measuring.

Although Aerophotogrammetry mapping efficiency is very high, but the mapping accuracy is limited. Therefore, there must be non-photographic measurement of observables participation in regional networks combined adjustment in order to improve the accuracy of photogrammetry. Like control point measurement task is not an independent existence, must be based on better improve the measurement accuracy for the purpose of photography, combined with the technical requirements of Photogrammetry Surveying.
