New features and changes introduced in this version are

• Higher Resolution Atlas Data

• External Data Interface Improved

• New Interactive Interfaces

• New Analysis Functions for Geographic Data

• Other New Functions

Higher Resolution Atlas Data

There are now high-resolution country outlines and more city locations available through the worldhi database. The worldmap command automatically chooses this high-resolution data if the region's area is small enough.

The worldlo atlas file has been updated to make it coincide more closely with high-resolution coastlines and boundaries.

The worldmtxmed MAT-file provides a medium-resolution political world matrix map.

External Data Interface Improved

Importing high-resolution atlas data is now much easier with these two visual interfaces:

• Digital Elevation Map Data user interface (invoked with the demdataui function)

• Vector Map Level 0 user interface (invoked with the vmap0ui function)

Many of the matrix map data interface functions now automatically concatenate data across separate files.

The external interface now supports the GLOBE digital elevation map data, a product similar to GTPO30. Use the globedem function for working with that data.

New Interactive Interfaces

You can now adjust interactively, on a map display, geographic lines such as great circle tracks, small circles and sectors of small circles. Use the trackg, scircleg, and sectorg functions to make these interactive adjustments. While in an edit mode, you can drag the lines around on the map, modify the lines in a control panel, or read measurements.

There is a new visual interface to create colormaps. Use the cmapui function to invoke this new interface.

New Analysis Functions for Geographic Data

You can use the new elevation function to find the elevation angle of a geographic point.

The new gradientm function performs matrix map data calculations, including gradient, slope, and aspect.

You can use the new los2 and viewshed functions with terrain data to check the line of sight visibility between points or the visibility of entire regions.

Several new functions have been added to support polygon operations:

Function	Description
bufferm	Compute polygon buffer regions
polybool	Perform polygon Boolean operations
polyjoin	Combine polygon segments into a NaN-clipped polygon
polymerge	Merge polygon segments with abutting ends
polysplit	Separate NaN-clipped polygon segments into cell arrays
polyxpoly	Polygon intersections

Other New Functions

Several new functions have been added to support polygon operations.

Function	Description
contourcmap	Contour colormap and colorbar for surfaces
driftcorr	Heading to correct for wind or current drift
driftvel	Wind or current from heading, course, and speeds
flatearthpoly	Insert points along date line to pole
lcolorbar	Labeled colorbar
mapprofile	Interpolated lines connecting waypoints on a surface
str2angle	Convert formatted DMS angle strings to numbers
