    Hello,

    I 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.

    For 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.

    All 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?)

    Ideally, I just want to rent something. I have a ballpark number of $250 per day to rent something but if needed I could go up some on the $ if there's something worth the extra cost.

    I 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).

    So... what kind of unit would you recommend?

    What type of search terms would you suggest I put into Google or YouTube to get a better idea of what I need?

    I 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.

    TIA!

    You need to serch on Surveying GPS, some setups have a single unit, while others have base station and a roving unit that work together

    Thanks @Nuvi-Nebie ! I have done some searching but it's pretty overwhelming to be honest. What type is the best for getting within 1-meter precision? That would be an acceptable amount of precision for our purposes.
