Overview

Xtractomatic is a set of free tools, written in Matlab or in R, that allows client-side access of environmental data served on the ERD/CoastWatch ERDDAP Server.

The xtractomatic tools were originally developed for the marine biology tagging community to extract satellite data coincident to the tracks from tagged animals. The packages have been extended to extract a 3D cube of data and time series from the region defined by the polygon.

Features

Xtractomatic scripts work within R and Matlab to subset and extract satellite and other oceanographic-related data from a remote server.

Data can be extracted

• for a moving point in time along a user-supplied set of longitude, latitude and time points,
• within a 3D bounding box, and
• within a polygon through time.

Xtractomatic accesses data that are served through the ERDDAP server at the NOAA/SWFSC Environmental Research Division in Santa Cruz, California.

Xtractomatic also includes two helper functions to search for and obtain information about available datasets.
