Hello,\n\nI am bidding on wetlands delineation job that's located in south Mississippi. I need to use GPS to collect about 50-70 data points across 40 acres of land. The area is an open field that is absolutely flat. There aren't any trees within a 100 feet of the study area.\n\nFor the GPS data points I need sub meter accuracy on horizontal values. Would prefer same for the vertical but that's not imperative. I have used hand held GPS units over the years but have never used anything more sophisticated like these other higher accuracy units - hence the reason I'm here.\n\nAll I need is something to give me a GPX file so I can load in to the GIS software, in sub meter resolution (preferably one foot?)\n\nIdeally, I just want to rent something. I have a ballpark number of 0 per day to rent something but if needed I could go up some on the $ if there's something worth the extra cost.\n\nI am fairly tech savvy (but obviously not in this area) and am pretty confident I could pick up and run something more sophisticated (provided I get to read the documention beforehand).\n\nSo... what kind of unit would you recommend?\n\nWhat type of search terms would you suggest I put into Google or YouTube to get a better idea of what I need?\n\nI know there's probably some things that I have left out so please let me know if you need more info in order to help answer my question.\n\nTIA!
