  1. The first thing to do before mapping is to set up the camera parameters. Before to set up camera parameters, recommended resetting the all parameters on camera first. To set camera parameters manually need to set to manual mode. Image quality: Extra fine Shutter speed: to remove blur from photo shutter speed should be set for higher value. 1200–1600 is recommended. Higher the shutter speed reduce image quality . if there is blur in the image increase shutter speed ISO: lower the ISO higher image quality. ISO between 160–300 is recommended. if there is no blur but image quality is low, reduce ISO. Focus: Recommended to set the focus manually on the ground before a flight. Direct camera to an object which is far, and slightly increase the focus, you will see on camera screen that image sharpness changes by changing the value. Set the image sharpness at highest. (slide the slider close to infinity point on the screen you will see the how image sharpness changes by sliding) White balance: recommended to set to auto. On surveying mission Sidelap, Overlap, Buffer have to be set higher to get better quality surveying result. First set the RESOLUTION which you would like to get for your surveying project. When you change resolution it changes flight altitude and also effects the coverage in a single flight. Overlap: 70% This will increase the number of photos taken during each flight line. The camera should be capable to capture faster. Sidelap: recommended 70% Flying with higher side-lap between each line of the flight is a way to get more matches in the imagery, but it also reduces the coverage in a single flight Buffer: 12% Buffer increases the flight plane to get more images from borders. It will improve the quality of the map source: https://dronee.aero/blogs/dronee-pilot-blog/few-things-to-set-correctly-to-get-high-quality-surveying-results
  2. i just saw this on the news, nice design
  3. sep ganz, ehehehehe
  4. Dapat data shp untuk peta multirawan se Indonesia. silahkan dicek https://drive.google.com/file/d/1anG5xcA9uMo1P9jLeppBvEXpaExJsLhk/view untested, lupa dapet darimana link ini
  5. one of my favorite image hosting, , this is their announcement : Rest in Peace TinyPic
  6. I dont know about ready to use lidar for car, but I imagine you need to build custom for that for the start, the lidar sensor (velodyne) approx 8000 usd and above, and you need to custom mounting, cabling, controller and of cource laptop or pc for processing IMHO
  7. can you please elaborate in more details, post screenshoot please
  8. for this kind of high resolution data, I think better using another method, for example OBIA https://gisgeography.com/obia-object-based-image-analysis-geobia/
  9. not necessary to excel environment but : https://github.com/orbisgis/h2gis/wiki/4.2-LibreOffice
  10. true, Huawei already lead in their enterprise business, for example the first 5G implementation if they can make this Hongmeng a.k.a Harmony OS success, then they sure will be another titan in mobile business
  11. yes, the hardest part is build apps ecosystem for developers, make all the developers interesting with this new OS and build apps for it
