Viewing Datasets

What kinds of data can be viewed using GeoMapApp?

Your own data can be imported from tables, shapefiles or GMT .grd gridfiles and viewed in GeoMapApp by choosing an entry in the File menu.

In addition, over 100 diverse datasets are ready for viewing in GeoMapApp using the Available Data menu. More data and datatypes are continually being added. The following description is to show the user where to look for data and to give some idea of the breadth of datatypes available, not to be an exhaustive and up-to-the-minute list.

The File Menu

The following types of data, both hosted elsewhere and your own computer, are accessed by selecting them from the File Menu.

 

Choose:

Connect to WFS

Connect to WMS

Import Shape Files

Import Grids

Import Data Tables




The Available Data Menu

Select Available Data to access an extensive variety of data through the Custom Data Viewer and General Data Viewer

interfaces. Data pertinent to the NSF Focus Sites is grouped for convenience.

 

Open Searchable List and Select Data From Menu both lead to the same data.

The user may choose the more convenient interface style.


The Search panel: enter any word and all dataset names containing that word will be highlighted.

You may go directly to a highlighted dataset.




Or you may choose among Custom Data Viewers (special interfaces designed to maximize the usefulness of specific datasets, see below), General Data Viewers (for viewing tables, grids and shapefiles) and NSF Focus Sites (see data in Ridge 2000 and MARGINS study areas).

Press OK to select dataset.


Custom Data Viewers

Custom Data Viewers are interfaces designed to maximize the usefulness of the dataset you are browsing. Click the links for information on viewing each data type.


Bathymetry, Grav and Magnetic Profiles

Multibeam Bathymetry Swaths

PETDB Bedrock Geochemistry

Earthquake Locations and Epicenters

Seafloor Eqs and Volcanic Eruptions

Multichannel Reflection Profiles

Single Channel Reflection Profiles

Seafloor Magnetic Anomalies

Drilling-DSDP/ODP/BRG



General Data Viewers

Datasets are listed in an extensive file tree in the Available Data window. Double-clicking any folder icon opens the folder and displays its contents. This view from April, 2007 contains over 50 datasets grouped under the general headings of Tables and Layers, depending on the structure of the data (determines the display options available in GeoMapApp). Data in the National Science Foundation's MARGINS and Ridge 2000 program areas of intensive scientific study are grouped under NSF Focus Sites


General Data Viewers - Tables

For help loading and displaying any of the datasets below, see Import Data Table Help.

The Tables list contains about 45 datasets that are ready for viewing in GeoMapApp. Double-clicking any folder icon opens the folder and displays its contents. You may enter any search term. As of April, 2007:

NSF Focus Sites

Data from the MARGINS and Ridge 2000 programs is listed under the NSF Focus Sites heading. There are over 60 entries as of April, 2007. More data is added as it is received.

For help selecting and loading any of these datasets, see Layers Help.

The View Menu - Grids

allows the user to change the global DEM data type (background) viewed in the Main Map Window. Topography is the default. Gravity or Geoid height may also be selected.

In GeoMapApp South, Topography is the only option.
