How to Export from DatuBIM (by Datumate)

  1. Start by creating a new project, click ‘New Site’ in the top left corner.

1a. This will open the Create New Site window and bring you to the Site Info tab. Fill in your site name, type, address, description of the flight collection or project details, project start date, and end date, and click Next to move to the Settings tab.

1b. On the Settings tab, enter the Units, Volume Units, and Coordinate System for the project and select Next to move to the Users tab.

1c. Enter the name of the account user associated with the site and click Create Site to close out of the window.

2. In the left pane, select the new site. This will open a new Upload Flight Data window. The first step is to add your images by dragging & dropping the selected images into the grey pane on the left labeled Drag and Drop images here, or by selecting Select Images and navigating to the folder that contains your images.

3. After your images have uploaded, you will see a list of the number of images and a thumbnail for each image in the left grey pane. If you are missing images, you can select Add More Images at the bottom. You will see a warning notification in the bottom left if there are any issues with your data, as well as dots on the map representing each image location and a red bounding box around the area. Once you have verified all images are uploaded, in the correct location, and don’t have any warnings, you can click Continue in the bottom right to move to the Flight Info & Preferences tab.

4. In the Flight Info & Preferences tab, fill in the flight details with the date the project was flown, the camera model it was collected with, toggle the RTK field on/off if you did/did not use an RTK system, note the operator, and any comments about the flight collection procedures. In the Georeferencing section, select one of the three options based on the nature of your control (see 4a-4c below). In this example, we selected 4b. Drone GPS & Manual GCP markup. Once selected, click Continue to move to the Model Pre Processing tab.

4a. Automatic geo-referencing based on your previous flight is only valid if you have a previous collection of the same area that was processed in DatuBIM. The images will use the previous control points and imagery as control.

4b. ‘Drone GPS & Manual GCP markup’ uses a control file (uploaded as a .csv in the specified format) to insert control points in the window and requires manual selection of the aerial target in a minimum of two photos per target.

4c. ‘Automodel based on drone GPS’ will process the imagery with no external control points and use the location information from the drone

5. In the Model Pre Processing tab, you will see the status of the uploaded images. Do not exit this page before the upload is complete. When the images are uploaded, your status will change to ‘the Model Pre-Processing has started’ and you can click ‘Close & Notify’ to close the window. You will receive an email notification when the processing is complete.

6. Once the ‘Model Pre Processing’ is complete, you will move to the GCP Marking tab

6a. Upload your csv file by clicking Import GCPs in the bottom left corner. Your csv should be in the format below (name, n, e, h) which is (name, northing, easting, height).

6b. Once you select your file, it will start processing assumed locations in the imagery. You can wait for it to finish or click ‘click here’ to start tagging your GCP locations manually.

6c. Once all GCPs are loaded, you will see the location displayed on the map and can adjust each GCP to the location of the aerial target in each image by clicking the GCP name. Select if they are to be used as GCPs or CPs under the Checkpoint column.

6d. When you select the GCP, a new window will pop up with the estimated location as a pink triangle and a cyan blue cursor. Mark the center of the target (in this example, the intersection of the two orange triangles) with the cyan cursor and click next to continue marking in all images. Click ‘Save Marking’ when all images with that GCP are marked. Repeat this step for all GCPs.

6e. Once the GCP marking is complete, click ‘Check accuracy’ to move to the Model Generation tab.
