New Import

Prior to importing the data, it is necessary to arrange the data in the tool ingestible format. Please read Steps to Load LiDAR DAta in the Tool for more details.

Step 1: How would you like to upload the data? A: Upload through Amazon S3

When selecting the Select Importer URL, the path shown must be unique to each customer.

Step 2: How would you like to group your data?

In this step the user needs to specify how the frames need to be grouped together to appear in the tool as one sequence.

By Folder

Folder wise grouping of point cloud files. This option groups all the point cloud files inside a specific folder together. In the below example, when the user chooses the ‘By Folder’ option to create batches, the following batches are created

Batch 1: 2 frames from Folder_A

Batch 2: 3 frames from Folder_B

Batch 3: N frames from Folder_N

Note: Above image is an example to depict how the grouping happens. Things to keep in mind:

1. Folder with the calibration data MUST be named calibration

2. Folder with the ego_data MUST be named ego_data

By Folder with image limit

This option groups the frames inside a single folder based on the number provided and club the remaining into one batch.

Click on ‘Save Configuration’ once all the above steps are completed.

Estimated Data Import Time

Below is an approximation of import time based on number of frames* :

To upload 100 point cloud (.las) file of 1MB with 3 reference images it take ~ 10-15 mins

To upload 500 point cloud (.las) file of 1MB with 3 reference images it take ~ 1 hour

To upload 1000 point cloud (.las) file of 1MB with 3 reference images it take ~ 2 hours

* subject to network bandwidth

Accessing the Predefined S3 Bucket

By default iMerit provides Cross-account IAM roles for programmatic access to upload customer data into a predesignated S3 bucket.

These steps are for a customer trying to upload data.

1. Create an IAM role or user in the customer AWS account (role_1) .

2. Give the role_1 download permission (GetObject) and upload (PutObject) objects to and from the predefined S3 bucket.

{ "Version": "2012-10-17",
  "Statement": [
    {
     "Effect": "Allow",
     "Action": [
       "s3:GetObject",
       "s3:PutObject"
      ],
     "Resource": "arn:aws:s3:::<to be communicated by iMerit team>"
    }
  ]
}

Note: Please get in touch with iMerit for a custom bucket.
