Welcome to the Dapple Help Center. The following topics will help you start
browsing, discovering and displaying geoscience data.
Download and Install Dapple
- To download, go to
http://dapple.geosoft.com/default.asp and click the "Download Dapple"
icon. For system requirements and additional installation help, go to
- Once you have downloaded
"dapple-setup-2.1.4.exe" go to the directory you saved it to, and run it. The
Dapple Setup dialog will be displayed.
- Follow the directions on
the dialogs that appear. When the Installation Completed dialog is
displayed, click the [Finish] button to complete the installation process.
Dapple, Geosoft's global data explorer, is designed to provide an open
and optimal environment for visualizing, presenting and sharing massive
quantities of geoscientific data. Dapple, enables you to browse, discover
and display graphically rich data from global and corporate spatial servers
– Geosoft DAP servers, NASA servers, USGS servers, ArcIMS servers, and the many, many WMS
servers currently available. The easy to use interface contains five data
view windows and six main menus. See the Data view windows and Main menus
tables below for more details.
Data View windows
Global Explorer and Navigation
The Global Explorer and Navigation tools (top right)
provides an interactive 3D globe that enables you to view and
position the selected data from a satellite altitude to any
location on earth.
The Search window (top left) enables you to Search all available "Servers" or the "Web", using both
spatial extents and keywords. The search results can be viewed in either List
or for "Servers" in Tree view ()
and for the "Web" in Thumbnail view ().
Note: When the "Servers" tab is displayed in "List view" the results are displayed for one server
at a time.
Note: The "Web" search includes an automated cataloging system that is continually updating itself.
The Data Layers window (middle left) includes all the selected data and enables you to control the
display features and organise the data layers for optimal viewing.
The Overview map window (bottom left) enables you to select an area or using the dropdown list,
a specific region of the globe, for the best possible view of your data.
The Metadata window (bottom right) displays the Metadata that is associated
with the currently selected dataset. The selected dateset can be from either the Search or the
The File menu enables you to open, save, save as, set home view, and send your
current data view as well as open an image file. This menu also provides
the option to exit the application.
The Tools menu enables you to Search (search Servers or the Web), Add to Data layers (add selected
data to the Data Layers window), Remove from Data layers (remove the selected data from the Data Layers window),
and Create GeoTIFF Snapshot (create a GeoTIFF of the data currently displayed in the Global Explorer window).
The Servers menu enables you to Add servers (DAP, WMS, ArcIMS), Set Properties, Set as Favourite,
Add Browser Map to Layers, as well as Refresh, Disable and Remove a server.
The View menu enables you to set the following options for the global view, Grid overlay, Show place names, Scale bar,
Cross-hair, Compass, Information overlay, Tile download activity, as well as specifying the Sunshading,
Atmosphere. and Vertical Exaggeration settings.
The Setting menu enables you to set your default start-up home view. The
Setting menu also enables you to access the Advanced settings wizard,
which enables you to set up Dapple.
The Help menu provides a link to the about Dapple dialog, the
Dapple project homepage, Dapple forums, Dapple documentation (this help topic)
and to check for Dapple updates.
The ability to access data from global and corporate spatial servers (Geosoft
DAP servers, WMS servers, ArcIMS servers, NASA servers, and USGS servers) along with
the Internet is a powerful and
insightful way to work with spatial data. Dapple provides effective data
browsing tools for locating geoscience data, satellite imagery, remote sensing
data, geology maps, geophysical data, and many other data sets of interest to
- Open Dapple.
- To specify the spatial extents you can use the Global Explorer and Navigation tools, or in the Overview
map window you can select an area (including the entire globe) or select a specific region using the dropdown
list. You can further focus your Search criteria by entering "Keywords" in the text box () provided. To
clear the search parameters, click the Clear search ( ) button.
- In the Search window, select the "Servers" tab and click the Search () button.
The Available Servers will be searched for any data that falls within your spatial extents and matches
your keywords. (Note that, when you select the "Web" tab the Internet will be searched for data files
that falls within your area of interest and matches your keywords.)
The results, which are displayed on the "Servers" or "Web" tabs, and can be viewed in either
List view or
Tree view (for Servers) or Thumbnail view (for Web).
- To view your search results, the selected dataset(s) must be added into the Data Layers window. To
do this, select (highlight) a dataset from the "Servers" Tree view or select
multiple datasets from the List view. Note that, you can also select
multilpe datasets from both the "Web" List and Thumbnail views.
Then, right-click and from the popup menu, select Add to Data Layers.
The selected data will be added to the Data Layers window (Note that you can also use Drag-n-Drop
to move the "Search" result datasets to the "Data Layers" window).
- In the Data Layers window you can use Drag-n-Drap to organise the
data layers for optimal viewing. Any metadata associated with the selected Data layer, will be displayed
in the Metadata window.
- To create a GeoTIFF snapshot of your current view, click the Create a GeoTIFF
button. Specify the GeoTIFF name and directory and click the [OK] button. A GeoTIFF of your current Global
Explorer view will be created.
- For more information on all the available options, see the table below.
Once you have selected a data set of interest in the
Servers window, right-click and from the popup menu, select Add to
Data Layers (or double-click on the selected data) and the data will be displayed
in the Data Layers window (middle-left) and when checked ()
is visible in the global explorer view, uncheck to remove (hide) from the global
The Layers tools are provided to enable you to control
the display features, including the transparency and view window. Use Drag-n-Drop to
specify the rendering
order of the selected data layers in the global explorer view. See the Data Layers
table below for more details.
Data Layers window
Once you have displayed your selected data layers you can use the
Navigation Tools to better view the data in the global view window.

What version of DirectX and .NET do I need?
Dapple uses the Managed Extensions for DirectX (MEDX), which exposes DirectX 9 to managed code. NONE of the operating systems come with MEDX by default, as it is not part of the core DirectX package.
Users can get the Managed Extensions for DirectX from the DirectX End-User Runtimes (the latest version of this is February 2010, available at: http://www.microsoft.com/downloads/details.aspx?familyid=0CEF8180-E94A-4F56-B157-5AB8109CB4F5&displaylang=en). MEDX can be installed on any of the five operating systems listed.
Almost every XP computer will already have some version of MEDX already installed from some program they have installed in the last three years. Vista and 7 computers often as not are missing MEDX.
For MEDX, if a user attempts to install Dapple on a computer that is missing MEDX, the install will display a message telling them they are missing MEDX and will provide a link that they can follow to obtain it. The installer will then close.
For .NET, no specific check is made. But a user will be prompted to install during start-up. However, Vista and 7 come with .NET 2.0 as an OS component.
