4.4 Create a Task

It's time to start a task for processing the images uploaded in DroneNaksha.
Start a Task
To perform a task, the user has to select task execution parameters such as outputs and the accuracy required.
  • Orthomosaic: Orthomosaic map or image will be created by stichting the images uploaded and processed. By default, this output will be generated.
  • Elevation Model: Elevation models such as DSM, DTM will be created after processing.
  • 3D Model: 3D Model will be created by selecting this type of output.
Selection of Accuracy
The user can select the accuracy level from the drop-down list as shown in the above image. The user can set the accuracy level as:
  • Low
  • Moderate
  • High
  • Highest
Click on the "Yes" button to proceed for creating a task. The task will be created successfully. Click on the "Ok" button to proceed.

4.4.1 Task Process Status:

Pending: The processing time required for a task will be more as it contains a number of images.
Details of a Task
The above image shows the details of a task under processing. It shows the status of processing, date, and time of creation of a task. It also displays the details of the output to be produced after processing such as orthomosaic, elevation model, 3D models with an accuracy level set for that particular output as shown in the above image.

Task Status:

Click on the bell icon to get the task status. Task status will be as good as a task log generated due to various processes carried out. These are as shown in the following image.
Pending Task with Usable Images
It gives the date-wise information of the processes carried out.

4.4.2 Manage GCPs:

Ground Control Points (GCPs) are actual landmarks that are accurately measured using GPS or other surveying methods and placed on the ground. The orthomosaic's accuracy can be increased during image processing by using GCPs, which are visible in the drone photos. The spatial accuracy of the final map can be greatly improved by incorporating GCPs into your drone mapping project, providing trustworthy data for a variety of applications.
To manage GCPs, DroneNaksha provides a feature by using "Manage GCP" option by clicking on three dots on the right-hand side of the screen.
Click on three dots to get the option to manage GCPs as shown.
Selecting Manage GCP option
The following image will be opened after clicking on the option of "Manage GCP". The image will have many blue spots that are related to the geographical location of the images captured a drone.
After Applying Manage GCP option
Click on any desired blue point to get the detailed geographical information of the selected image as shown such as latitude, longitude, and altitude. It also displays the details of pixels and the size of an image in MB.
DroneNaksha provides a list of GCPs on the right-hand side of the screen which includes the number of total predicted GCPs and Marked GCPs.

4.4.3 Download CSV Template

DroneNaksha provides a few CSV templates which can be used to store the information of CSV in that particular format.
Click on "Download CSV Template" option to get the details in the prescribed format.
One ZIP file will be downloaded that includes two files as shown
Download CSV Template
  • GCPTemplate(Degree): This file contains the details of latitude, longitude, and altitude.
  • GCPTemplate(Meters): This file contains the following information in Excel format. It includes details of northing, easting, and elevation in meters.

4.4.4 Manage CSV

Manage CSV
The user can import CSV format in the prescribed format as shown in the image by clicking on "Manage CSV" option from the right-hand top corner.
Import CSV
The user can browse for any specific CSV file from his computer or "Import" a CSV file from any other source.
Once the processing of a task is completed, the task process status will be changed to "Completed" and it produces the outputs which are discussed in the next section as "Visualization".
