xtractomatic is an R package developed to subset and extract satellite and other oceanographic related data from a remote server. The program can extract data for a moving point in time along a user-supplied set of longitude, latitude and time points; in a 3D bounding box; or within a polygon (through time). An update to the package has been released. The major change (besides some minor bug fixes and prettifying of code) is the inclusion of some 20 new datasets. These include the reprocessed SeaWIFS chlorophyll data (R2014.0), MUR SST v4.1, a MUR-based SST anomaly, a 750m VIIIRS chlorophyll dataset for the North Pacific, a HYCOM-based estimate of sea surface height, and an estimate of frontal probability.
I am slowly working on getting xtractomatic suitable for submission to CRAN, in the meantime the instructions for installing the package can be found on the Github site https://github.com/rmendels/xtractomatic. Also there is the wonderful "rerddap" package from the rOpenSci folk which is available from CRAN.
