It is malicious and innapropriate to discredit a company based on rumour.
There are two sides to this story.
I flew a few contracts for DIMAP over a few months. Their products met industry standards, management was professional and compassionate and the company was generally well organised.
I would not hesitate to fly for them again, nor would I hesitate to consider buying survey data from them.
I have a related degree, and several years flight and ground survey experience.
It's a dog eat dog world out there.
