Using the Site Scan Manager to combine multiple flights into a single model

Now you can access, share, and process your data from any web browser. The Site Scan Manager allows you to view photos from previous jobs; download orthomosaics, point clouds, and meshes; create new jobs; and download photos in an easy-to-share zip file. Each of these features unlocks many new workflows, but specifically this tutorial explains how to combine multiple flights into a single model. This is useful to combine Surveys spanning multiple missions into a single orthomosaic (as long as you stay below 500 images), to combine oblique and Nadir imagery to generate a single point cloud of a structure and its surroundings, and to combine a Crosshatch survey with Manually acquired oblique imagery to automatically scan the majority of a building while hand-flying tricky or overhung areas.

To see a visceral example of how this works, take a look at the images below. I used an Area Survey to generate the ortho below that provides site context and existing conditions.

However, an ortho generated from Nadir imagery does not necessarily generate an accurate model or point cloud of a structure.

To capture the oblique imagery, I performed a Crosshatch Survey and used the Site Scan Manager to combine the two datasets. This allows me to work with a single model that contains both specific details and general context.

Combining 2 jobs on the Site Scan Manager

1. Go to sitescan.3dr.com and log in to the Site Scan Manager using your Site Scan credentials.

Click on the top center of the screen to open a drop down window showing your different Projects. Select the one where you can find the Jobs you want to combine into one.

2. Using the Job selection window at the top left, click the first of the jobs that you would like to combine into a single point cloud, mesh, or orthomosaic.

3. Click on the “Share” icon at the top right corner and then within the “Share Photos” tab, click on the Download button and save them to your computer. Repeat these steps for all of the jobs you would like to combine, keeping the 500 photo limit in mind. In the event that you do need to go beyond this limit please contact our Success Service team for further assistance.

4. Going back to the Job selection window, click on it to reveal the list of Jobs available within the currently open Project, but this time select “New Job” at the bottom of the list. Once you do this a new window will apear allowing you to name this new Job and giving you the option of selecting what Project you want it to be under. Once you select it click on the “Create” button.

4. Drag the images you just downloaded into the dotted box and wait for them to upload. Note: This tool can be used for combining Nadir and oblique imagery, terrestrial with aerial imagery, combining multiple Surveys, or anything within that context.

5. Once the images are uploaded make sure you have selected the correct Job from the Job Selection window and initialize processing by clicking on the “Process Job” button.

6. If you haven’t done it yet, this will ask you to log into your Autodesk A360 account. After logging in the processing phase will start. You can tell that the Job is processing by the icon that appears next to the “ortho” section under Data Layers.

7. After processing is complete, click the Share icon at the top right corner of the screen which will open a window with all the resulting files. Clicking on any one of them will initiate the download of said file.

Note: As a reminder, Ortho generates a georeferenced, scale orthomosaic, RCS generates an Autodesk-format point cloud, RCM generates an Autodesk ReMake-format mesh, OBJ generates an open-format mesh, and LAS generates an open-format point cloud.
