Introduction
This was a fairly brief lab that was more of a introduction into our final project. The main purpose of this lab was to use our hand held device (i.e. Phones) to collect GCP points. The reasoning for this is so that we can see how imports it is to use industry grade gps systems as our cellphones GPS system will not correlate exactly with the GCP points we were wanting to collect.
Methods
Step 1: Fill out dispatch form requesting the proper drone for checkout which in this case will be a Mavic 2 pro. In this form I will also need to provide the number of batteries I would like as well as any additional equipment such as landing pads that will be used.
Step 2: Process a request to conduct your mission with the forestry and natural resources department. Make sure to include all days if this operation will take place over the course of multiple days.
Step 3: Go through the Mavic 2 pro Checklist. It is critical nothing be deleted off of this checklist however if you would like to add additional safety measures to this checklist that is also encouraged.
Step 4: Using Esri field maps make sure to collect the proper GCP positioning. Make sure you're positioning of the GCP points are accurate as to not cause any problems later with data processing.
Step 5: Fill out the Metadata form. This is extremely important as in this form you should also take notes on any important or relevant information that may affect or that may have affected the mission. The more notes you take the better and be specific.
Step 6: Make sure to draw your mission out using an approved UAS flight platform such as that as Pix-4d. When drawing out your mission it is important to over extend the flight area by roughly 20% so that during the flight none of the GCP point are omitted from the data hence causing a major problem.
Step 7: After completing the mission you should review your data collected to ensure that all the GCP points where indeed captured during the flight. By doing this you are are avoiding having to potentially go out into the field again and are able to get the data collected more efficiently and in a timely manner.
Step 8: Properly Process the data in Pix 4d. Make sure to manually mark a few GCP points so that Pix-4d can adjust the data properly to match the data collected including the GCP points. With this also make sure to review the processing documentation report that PIX 4d will generate in terms of the quality report.

As you can see when planning is important to make sure you over-extend your mission plan so that you can ensure that all GCP points will be properly captured during the flight.
