  • Batch Process for "Export Mbtile format" for bulk tif images

    Hello,

    You can use the EXPORT_WEB script command in a batch export of MBTiles data.  If you are new to Global Mapper scripting, we have an introductory, prerecorded webinar here.

  • Cast shadow analysis

    I am currently wondering about the analysis of cast shadows based on the the terrain.

    My background is, that I am trying to simulate the near shading effects by trees, buildings and other elevated objects onto lower terrain to see if the terrain behind / below will be shaded during specific hours of the day.

    I figured out, that the shaded relief function allows for setting of different sun angles and azimuth and so I tried to work with this. However, it appears to me, that this functionality will only display, whether or not a specific area would in theory receive direct sunlight but it does not cast / show the shadow, which an object will throw.

    So for example, I am attaching a view from a 3D model, where I overlaid three hill shading options. The model is located in Yamagata, Japan.

    Option 1 (10:00 am)
    Sun angle 24.5°
    Azimuth 155°

    Option 2 (12:00 pm)
    Sun angle 28.5°
    Azimuth 180°

    Option 3 (14:00 pm)
    Sun angle 20°
    Azimuth 215°

    I am aware, that the above numbers are not 100% correct, but it is accurate enough for my purposes.

    My point is, that the programm just creates dark areas, where there is no direct sunlight, but it does not cast shadows. In this case, there are two buildings in the centers, which are roughly 30m and 40m high and they would probably cast quite far shadows behind them.

    Is there a way to do this? I would like to see, how far shadow is reaching but right now it seems that the programm is not doing that.

    Regards,

  • Any options to export TIN to LandXML in GM

    I'm running into a strange issue where the land/xml file is reporting as metric, even though all the data and all the settings I have set are US Survey feet. We were not experiencing this issue in earlier builds.

    Thank you for your help-

  • How to combine multiple .mbtiles files into single one ? (purpose is to web upload)

    Hello,

    From that image, it is difficult to be sure, but it appears that you are exporting a large area (most of which is blank) at a high resolution, and exporting a lot of zoom levels.  Here is another approach that should work:
    1. Load one of the layers.
    2. File -> Export -> Export Web Format..., and choose MBTiles
    3. Tiling Options: Set your zoom levels, and other options
    4. MBTiles Options: Remove check next to "Delete Intermediate Tile Files", and choose a Location directory.
    5. Click OK to perform the export
    6. Load the other layer
    7. File -> Export -> Export Web Format..., and choose MBTiles
    8. Tiling Options: Set your zoom levels, and other options
    9. MBTiles Options: Remove check next to "Delete Intermediate Tile Files", and choose the same Location directory as you used above.  You may get a warning about the directory not being empty, but you can ignore it.
    10. Click OK and choose an MBTiles file name that is different from the one you used previously.  After you are done, this one should contain all of the tiles from both layers.

  • Automatic classification of moving objects and Road features using GM script for LiDAR Module

    Dear All,

    I wanna know the way to write script for automatic classification of moving objects (like cars) and Road Features (like white markings, lanes) using GM script. I have airborne LiDAR data and I need to classify the road features. It took more time to classify it manually using GM LiDAR module. Is there any possibility to run auto routine through script? If yes, it would be helpful. 

    Thanks,
    Sandhya Mary

  • Point Cloud Classification Settings

    When you open the case study and receive the file-not-found screen, edit the address to remove the characters after ".pdf" and the file will then open fine.

  • Point Cloud Classification Settings

    Thanks for response, Katrina.  I have seen the excellent webinar.  The issue seems to be with the higher point densities of the photo generated point cloud.  I will continue to work with smaller sections.  I don't know if there are any recommended settings for such a file as a starting point.  Using '1 point' spacing for the gridding seems to tight, and 1 or 2 meters may be to large.  There are so many settings, it is a little daunting. I know there is personal training available; however, is there a chance to just talk with someone on the phone for a short conversation?  BTW, the link for the case study above did not work.
