OdaStat-G Software can also be used to configure instrument parameters such as setting calibration levels and logging intervals. Users can also save a preferred configuration or set of instrument parameters and then reuse the configuration file to download to multiple OdaLog instruments (of the same type). Flowlink ® Download.

Data and Package Basics
Download Flowline Drivers License
The first thing you are going to need to do is go get some data to work with. nhdplusTools provides the ability to download small subsets of the NHDPlus as described in the Discovery and Subsetting section. For large subsets, greater than a few thousand square kilometers, you can download the National Seamless database at this web page. You will need 7z or the archive package to extract it.
If you are working with the whole National Seamless database, nhdplusTools has some convenience functions you should be aware of. Once you have it downloaded and extracted, you can tell the nhdplusTools package where it is with the nhdplus_path() function.
If you are going to be loading and reloading the flowlines, flowline attributes, or catchments, repeatedly, the stage_national_data() function will speed things up a bit. It creates three staged files that are quicker for R to read at the path you tell it. If you call it and its output files exist, it won’t overwrite and just return the paths to your staged files.
As you can see, stage_national_data() assumes you want to stage data in the same folder as the nhdplus_path database and returns a list of .rds files that can be read with readRDS. The flowlines and catchments are sfdata.frames and attributes is a plain data.frame with the attributes from flowline. Note that this introduction uses a small subset of the national seamless database as shown in the plot.
NHDPlus HiRes
(6/16/2019) NHDPlus HiRes is an in-development dataset that introduces much more dense flowlines and catchments. In the long run, nhdplusTools will have complete support for NHDPlus HiRes. So far, nhdplusTools will help download and interface NHDPlus HiRes data with existing nhdplusTools functionality. It’s important to note that nhdplusTools was primarily implemented using NHDPlusV2 and any use of HiRes (which is still “beta data” as of writing this) should be subject to significant scrutiny. Never the less, here’s a short summary of how to work with NHDPlus HiRes.

For the demo below, a small sample of HiRes data that has been loaded into nhdplusTools is used. The first line shows how you can download additional data (just change download_files to TRUE).

Other functionality in the package, such as the get_UT/UM/DM/DD functions, subsetting, indexing, etc. also work now or will soon! Stay tuned for a dedicated NHDPlus HiRes vignette and submit issues as you find them!
