"My favorite is Getac X500 with 800 nits and touch screen. Unfortunately is heavy and expensive but..."

"@Jani The door analogy is so true in the state, government and any other less responsible kind of ownership. But I think that here in Europe those things are slowly changing due to financial crisis. In my sector (LIDAR & photogrammetry) the…"

"It is a render of DSM (Digital Surface Model). Actually if you look closer you can se that is composition of several renders (azimuth of light varies). Quite common image in my workflow."

"... and I'm working in visualization of those and comparable objects (powerlines,...) using LIDAR data. Investors are regularly under attack from local communities due to visual impact ;-) For smaller projects, your services Krzystof can be…"

"Well I guess not. Except in a case when rows are also one inch apart. 5-10cm GSD should be enough for this. Anyway NIR image in grayscale color is more useful in analysis than false coloured one."

"I think that we didn't understand each other. I was talking about GPS+RTK method only in GCP acquisition. In Pix4d workflow GPS coordinates just helps to order images for faster tie point search. In the worst case I doubt that they even need…"

"The holly grail in photogrammetry is around 0.3 pixel error. Krzysztof do you know what kind of camera parameters (principal points, focal distance, distorsion,...) does Pix4d estimate? I think that with at least 4 GCP (Ground Control Points)…"

"Well I'm quite sure that they are already working in this direction. They seem to be near that target. The main obstacle as I see is high quality automated seamline creation in urban environment where roof edge detection and detection of other…"

"Well I have to say that in some cases we did an orthophoto in 48 hours with 40Mpx camera and LIDAR for areas of several km2. 16-20 working hours. 24 hours is not possible in cloud computing due to image distribution but here I'm talking about…"

"I would like to produce such orthos in less then 24 hours. Is it possible? I think that it is or will be in less than a year. The only problem is high quality seamline creation. Especially in urban area (buildings). True ortho is a good option but…"

"Well if regulator demands a military grade AP then there is no second choice, but if this is not the case, then it is way too much. BTW I have played with AgiSoft software and I've ti say that it is quite good and also fast. Using some LIDAR…"

"50K€! For this I can get 30-50 of helicopter hours with LIDAR (>10 pt/m2 and less than 10cm images). If we are talking about 10k€, then it can be contender, but not with 50k€."

"@Rocca: Well I saw some results where GPU SIFT was used on large number of images that hasn't any kind of georeference information. Its speed is impressive. Almost 1 image (5Mpx) per second. Anyway, there are two working options for me: 1.…"

"@Rocca: Are you also using a GPU SIFT approach and what is maximum image size (pixels) that you can put trough whole process?"

"@Rocca: I'm primary looking for a software. And I'm a fan of command line. Batching processes is priceless for my lazy nature ;-)"

"And for orthorectification terrain (DEM) is necessary. I'm afraid that APM data are not precise enough for this task. I'm working with optical IMU with geodetic grade L1/ L2 GPS reciver and GPS measurments are post processed with GPS base…"
