    Even if btbevo.exe is in the confident list, the same problem remains. I have reinstalled btb, put the license file in the folder, and the detection happened again. So I have to quit Kaspersky in order to use btb. Not a smart solution, but at least, it works.

    Hello everyone,
    coming back to the BTB 1.0 topic, I would like to ask if anyone used successfully .asc LIDAR files in BTB. I got some UK files for test, but they are not in the format requested by BTB, they are text files with .asc extension, with 1000 lines per 1000 rows filled with, I think, x,y,z values separated by spaces and the . decimal point.
    Maybe some way to convert them into something importable?

    Any help will be greatly appreciated.

    I have that problem with importing the lidar data.
    Loading the Lidar data that comes with BOB's work fine.
    But when i load my own i get this error message.
    It's quite a detailed scan of 0,5 x 0,5 meter.
    First my file was just to big.
    So i cut it up in multiple parts to make it easier to handle.
    My lidar data comes without intensity or color.
    It's just XYZ.
    I made sure intensity and colour data is not imported.
    After importing it tell me 10.000 points are loaded.
    So far so good.

    But when try to show the location data I get this message.
    Value of '-2147483393' is not valid for 'green'.
    I seen you said there is a workaround.
    But i don't get that workaround at all.
    Should I add some extra rows with fake data?
    Clearly there is a bug in bobs, if it can't even handle such a simple file.

    Here is a sample of the data in the CSV file.
    516.49,886.42,11.43
    516.47,887.55,11.70
    516.18,887.29,11.65
    515.88,887.04,11.59
    515.59,886.78,11.51
    515.29,886.55,11.54
    515.00,886.30,11.52

    Richard - I found you need to add an intensity column and fill it with fake data.

    ok thanks.. i make another one up.
    Quite a flaw in Bob's that it needs this data even when you unclick it.
    But i give it a go this evening.

    Have tested it out with the fake intensities values.
    Been working my way trough LasTools, a truly great program for previewing, merging, cropping & XYZ positioning of LAZ files.
    With LasTool I merged 2 lidars, 1 from the ground + 1 from everything above ground.
    So all the buildings and fioliage are seperate accessable from the ground lidar.
    Than did output from .laz to .txt and renamed the new .txt file to .csv.
    After that some CSV Ed to add a empty 4th column.
    Than with CSV Ed I inserted the fake intensity values.
    With CSV splitter I cutted the much to big file CSV containing 27.000.000 points in smaller CSV files of "only" 600.000 points.
    Import than finally worked flawless! FInally.
    Still some funky color i guess from the fake intensity.
    But hey the data is there and much more detailed than i hoped for.
    It almost looks laserscanned.

    Anybody guess the track?

    Hi Richard,

    Where did you find the LiDAR data for Zandvoort? I've not been able to find any European data.

    All of Netherlands has had an aerial LiDAR survey done by the water board(s), the people who control the dikes. That is out there as a public download, but I couldn't find an index into the files, so haven't added it to my list. The ArcGIS folks and/or AutoCAD folks also have Zaandvoort as a demonstration file.

    Here you can find Lidars of the Netherlands.
    Comes in 5x5 meter or in 0,5x0,5m resolutions.
    Than it's splitted in grounddata and everything above ground.
