How to treat the prospect of photogrammetry and remote sensing technology specialty?

Photogrammetry and remote sensing are two industries with different emphases. Even photogrammetry and remote sensing themselves involve many fields, but they are all technical means. As for the prospect, it depends more on the utilization degree and demand of their achievements between industries. But what is certain is that both of them are the inevitable trend of future development. The main challenge is accuracy, because accuracy determines the degree of utilization.
