Dear GeoMapApp community,

We are pleased to announce a new release, version 3.4.0. Highlights of the release include several enhancements and bug fixes.

Also, Mac users running 10.8.x or 10.9.x and higher that have trouble downloading the new application should see our FAQ page for instructions.

The GMRT base map Tiles now load sequentially allowing the map to be refreshed more quickly when zooming and panning. At the bottom of the window frame, Elevation Data Sources can be listed, with updated country flags showing the nations that have contributed data for the GMRT elevation model.

A Save Sessions/Import Sessions function is now available. It provides limited ability to save, store and re-use an instance of a GeoMapApp session. Saving a session under File > Session Manager captures the loaded data portals and data layers as well as the map location and zoom. When a saved session is imported, the application automatically zooms to the pre-set map area and displays the previously-loaded data layers and portals. The choices to zoom and load all layers are also added to the My Layer Sessions menu. Save Sessions/Import Sessions functionality could be useful for teaching, allowing an educator, for example, to have all students start GeoMapApp at the same view with the same data sets loaded.

When point data is loaded, improvements to the load/import data sets and decimation of points allow better control of the number of points plotted on the map. If a data set contains more than 20,000 records, a choice is given to plot all of the points (potentially impacting graphics card performance) or to plot a geographically-decimated subset of the points (may not display all valid points). When importing ASCII data from a URL, the import function prompts the user if the data set has more than 100,000 points. The ability to sort a data column has been improved.

Progress bars and status messages for the Multibeam Swath Bathymetry portal have been updated. Once loaded, the Multibeam Swath Bathymetry portal is cached automatically, making subsequent loading times very fast. The Ocean Drilling portal is now correctly released when closed.

When importing multiple grids, the geographical bounds and Z-range of the selected grids are now correctly identified. An optional one-click import function accepts and applies those bounds to all of the chosen grids.

The availability of Tear-Off Menus is highlighted at the top of each menu - when clicked, a separate navigation window helps users quickly navigate the menus.

Other improvements and bug fixes requested by the GeoMapApp user community have also been included such as the location of saved files now defaulting to a user's home directory, a clearer distance scale bar, and fixes to correctly display the red-green-blue symbol colors of an imported spreadsheet or data table. Tool tip information was also updated. Visit the GeoMapApp development history page for more details and a complete list of changes.
