I’m looking for some advice and guidance on a project that I may have the opportunity of using DD on. I’ve been using DD for about 3-4 months now and It’ll be the first time introducing it to an interested client. The potential client that is interested owns an industrial repair yard and they are planning on going through a reconstruction of the entire site.
I’m using the Phantom 4 pro V2.0
The site is about 84-91 acres based on my flight plan.
The land is primarily flat here so there are no drastic change in elevations.
There are 2-4 Tower cranes on the dock area (so I will need to factor
that into my flight alt) I’m thinking I will need to be 250’ at least but I wont
know for sure until I actually do a site visit.
The site consists of flat buildings, warehouses, fabrication shops, etc.
It will the largest area I ever had to cover and I’m unsure of what flight modes will produce the most useful results. I’m currently on the pro plan and will undoubtfully upgrade to the business plan if I secure the job.
Will I need to invest in GCP’s? Because the site primarily consists of mostly buildings, steel materials and constantly moving equipment I’m thinking that relative accuracy may be sufficient considering they will mostly use my services for construction progression updates.
If I need to cover the dock area that the tower cranes are stationed on and they are above 250’ alt, is it good practice to fly the entire site at the same alt or can I lower my alt for the areas that I can increase the resolution of the map?
Any assistance and concerns are greatly appreciated.
