To create an orthomosaic with PrecisionMapper desktop app using Simple mode, follow these steps.


1. Navigate to PrecisionMapper desktop app and provide details like project name, the storage location,
     and click Ok (Figure 1).


Figure 1: Creating a project



2. Click Add Images, selects images from your survey folder (Figure 2).

3.If your survey is carried out with multispectral sensor, then click Manage Multiband Calibration to calibrate multispectral bands. 

Otherwise, click OK to confirm your selected survey images and continue with next steps (Figure 3).

4. In the absence of inbuilt GPS parameters, click Add Telemetry and select GPS parameters
     file (telemetry file for PrecisionHawk drones) (Figure 4).

5. Adjust the GPS table (Figure 5). 


     5.1  In Table Formatting section,

                 Adjust the table with the help available features like Skip _ no. of rows,
                 header row checkbox, and Column separator option.


     5.2   In Position Input section,

                  Select the column numbers as per their respective GPS values.

                  (For example, as per your telemetry file table, if the Latitude is present in the 2nd column,
                  then select 2 in Latitude starting from the Column drop-down box.
                  Similarly, select respective column numbers for Longitude and Vertical). 
Click OK.

6. To add ground control points (if available), click Add GCP.

      After adding GCPs, click Next. This begins the Initial Process (Figure 6).


      Initial Processing consists of following steps.

      1.Feature Detection

      2.Feature Matching

      3.Structure From Motion (SFM)

      All of the above processes are auto-generated. You can see their status at right bottom
      corner of the screen.


      After completion of Initial Processing steps, click Next.

7. Crosscheck the GCP locations and click Next.


8. In Output Ortho Details section, enter the appropriate processing details and click Next

     (Figure 7).

9. PrecisionMapper desktop app creates an orthomosaic after completion of the following processes (Figure 8).

     1. Refine Using GCPs

     2.Undistort Images

     3.Create Dense Point Cloud

     4.Create Dense Point Grid

     5.Smooth Mesh

     6.Generate Orthos

     All of the above processes are auto-generated. You can see their status at right bottom
     corner of the screen.



10. To access the generated Orthomosaic, click Open Results Folder (Figure 8).
