Landsat 5 Stabilised and Investigated

The Landsat 5 satellite tumbled out of control and power was at a critical level in the early morning of 13 August. The cause for this anomaly is currently unknown and being investigated. The spacecraft has been stabilized after the USGS Landsat Flight Operations Team initiated recovery operations. Power is still at a critical level, and the extent of damage is yet to be determined. Imaging operations are suspended until further notice.     Landsat 5 was launched in 1984 and designed to last three years with a possible extension to five years. It is still a valuable resource and... (read more)

Landsat 5 Experiencing Technical Difficulties

On 26th November 2005, the back-up solar array drive on Landsat 5 began exhibiting unusual behaviour. The solar array drive maintains the proper pointing angle between the solar array and the sun. The rotation of the solar array drive became sporadic and the solar array was not able to provide the power needed to charge the batteries. Maintaining power to the batteries is critical to sustain proper operation of the spacecraft. The primary solar array drive failed under similar circumstances last January. As a result of this current situation, imaging operations will be suspended for at least the next two... (read more)

5 Questions to... Christian Heipke

The ISPRS Congress is in full swing. How did you experience it up to now? The congress is very well organized, there is a good atmosphere and the people are eager to learn. The presentations were interesting. The two fora were important, well attended and with a useful discussion. They were a bridge between science and application, contributing to the profession. You are now chairing the ISPRS. How do you feel about this? I feel good about it. It’s good to see the society move forward at this pace. Good to see that people want to take on responsibility in...

5 Questions to...Lena Halounov√°

The ISPRS Congress is in full swing. What was your experience of the first few days? That the Congress Director had no time to attend the Congress parallel sessions and interactive sessions. I would recommend the next one to read the papers during the reviewing process. Back in 2012 Prague won the bid to host the 2016 ISPRS Congress. Any regrets? No, not at all. I have met a lot of people I would have never met and I have visited many countries and exceptional places. All of that has given me a greater understanding of people from other countries...

5 Questions to…Martin Isenburg

GIM International took the opportunity to ask Martin Isenburg, founder of rapidlasso GmbH, a couple of questions - ranging from Lidar and the large number of conventions and tradeshows he attends, to his complicated relation with Esri.   You are the creator of some indispensable tools for the Lidar industry, such as LAStools and the compressed LASzip format (*.laz). Much of your work is also open source. What drives you personally to create these products? The open source library ’LASlib’ was originally written to support my scientific work as a postdoc at UC Berkeley. I was working on triangulating gigantic point clouds... (read more)

The overall opinion is that the gathering of geo-data is becoming easier through automation. It’s almost a ‘push the button’ and there’s your dataset. Of course this is something of an oversimplification, but since the advent of gps, rtk and automated total-stations, surveying is no longer difficult. On building sites it’s often not even anymore the surveyor who’s in charge of the total-station, but an engineer or building professional acting as data gatherer. Pessimists might view this with horror: the profession of surveyor on the verge of dying out. But believe me, it’s not. The reverse is true. The profession... (read more)
