Location accessibility:

 Aerial Imagery:

The reach of an aerial acquisition company is usually restricted to a specific area or country due to the fact that aircraft are based in a specific location. Remote survey locations attract higher mobilisation and logistical costs.

High Resolution Digital Aerial Imagery vs High Resolution Satellite Imagery – Part 1

The gap between these two usually complementary mapping technologies is getting smaller as both satellite and aerial imaging systems have benefited from great technology improvements in the last decade. These technologies can even overlap in terms of resolution, meaning that issues such as accuracy, acquisition and processing time need to be taken into account . It is more of a challenge to make informed decisions about which technology to choose for a mapping project. Nevertheless, each technology is alive and well and possess unique characteristics and strengths which need to be highlighted. Read more
