Best method for capturing Hiking Trails

I'm looking to see how best to be capturing Hiking trails. I'll outline my current process below

Currently, I go out on trails with a shoulder rig and a GoPro attached. I shoot in timelaps at .5s  for each image. What I've found in shooting at this interval and this setting is that each image holds the GPS cord along with allowing for enough shots so that as I move there's no loss in points that can be tied together. 

The only problem in this current method is by the end of a hike I have thousands of photos, when trying to put all that info through reality capture in a single go it's just too much as it's trying to go through miles of photos shot close up.

I've been chunking out these sections at an interval of 999 images per trail set and depending on my pace at the time covers roughly .25 of a mile. 

So what I'd like to know, is, is there a way I can use all these images to run through reality capture in one go so I have the whole trail. Or maybe being able to use these subsections that have already been created to then put together the whole trail? Am I currently capturing in a correct manor as well, the amount I capture is a bit excessive but ensures that each and every image has at least some for of crossover.

The last bit is, what can I do in this process to help reduce cost per model, a .25 mi section is roughly 16 - 20 and a single trial could easily end up costing  $560 to get every section of the model.


I look forward to hearing how I can improve the capture process.
