We'd like to read in locations of recent earthquakes from USGS website and plot them on an interactive map.
Antmap is part of Antarctic Mapping Tools for Matlab (Greene et al., 2017). Click here for a complete list of functions in AMT.
In this example, I will load an some historical data, earthquake hypocenters from the ISC-GEM Catalogue and see how we can work when the amount of data may be too large to fit into memory all at

The scalebar function places a graphical reference scale on a map. This function was designed as a simpler alternative to the built-in scaleruler function.
The gravity_data function returns gridded Antarctic gravity anomaly data from Scheinert et al., 2016. See the Data Citation section below for information about this dataset.
This function returns a logical array describing the landness of any given lat/lon arrays. Requires Matlab's Mapping Toolbox.
QUIVERMC is an adapted version of Andrew Roberts' ncquiverref. This function fixes a couple of problems with Matlab's quiverm function. The two primary issues with quiverm are as follows:
The pathdist function uses the distance function to calculate cumulative distance traveled along a path given by the arrays lat and lon. This may be useful when variables such as ice
This function returns the 1993-2014 linear sea level trend for a given lat/lon, in millimeters per year. Data from CU Boulder Sea Level Research group. Data of lower spatial resolution (1
This function employs the interpm function to densifiy lat/lon sampling in lines or polygons, but extends the available input units to include 'meters' or 'kilometers'. However, note that
Scarlabel and corelabel are part of Antarctic Mapping Tools for Matlab (Greene et al., 2017). Click here for a complete list of functions in AMT.
Icesat plots the grounding zone inferred by ICESat. Data details can be found here. This command has a rather general name for a rather specific function because it may be updated at a future
The fastscatterm function places color-scaled point markers on map coordinates. This is a much faster version of the Mapping Toolbox's scatterm function, adapted from Aslak Grinsted's
This function plots a subregion or continent-wide image of the center-filled 240 m resolution Landsat Image Mosaic of Antarctica. The mosaic is comprised of Landsat 7 images taken primarly
The reftrack function returns coordinates of ICESat's 91-day orbit reference tracks.
Scalebar is part of Antarctic Mapping Tools for Matlab (Greene et al., 2017). Click here for a complete list of functions in AMT.
The gravity_interp function interpolates Antarctic gravity anomalies to arbitary southern- hemisphere coordinates. Data are from Scheinert et al. 2016 and are described below. If you
The smithlakes function plots 124 ICESat-detected active subglacial Antarctic lakes identified in a paper by Smith et al. For details of the underlying data, read the Smith paper and data

Change a map projection when displaying vector data using geoshow . If you need to change projections when displaying both raster and vector geodata, you can combine these techniques.
