Through TMView, datasets with geo-spatial data
can be organized and visualized. Data is organized in TMView through
the MapSpace Manager window. The TMView Map Window displays
the Mapspace data graphically. You have learned how to view maps
using the ePublication MapSpaces that you installed and the sample
MapSpaces that came with the application download. You can also
create your own MapSpaces or download MapSpaces from the ECAI
Clearinghouse.
5.1 Downloading MapSpaces from the ECAI Clearinghouse
-
In TMView, go to MapSpace > Download
from Clearinghouse.
-
TMView will connect to the ECAI Clearinghouse.
Note: Periodic update of the TimeMap software and architecture
require users to update the software. If while attempting to
connect to the ECAI Clearinghouse you get a message telling
you the software is outdated, please go to http://ecai.org/tech/timemap.html.
-
Insert your selection parameters in the Metadata
containing box and click Filter for MapSpaces.

Select the desired MapSpace and click the
Download MapSpace button.
- Indicate where the MapSpace should be saved and click Download.
The MapSpace will come with pre-defined datasets.
You can download some or all of these.
- Select the datasets to be included in the download and click
Download Datasets.
- You will be provided with a status window to show the progress
of the downloads.
- When the download is complete, the TimeMap MapSpace Datasets
Download / Find window will update with green check marks
to show which datasets were successfully loaded. Click OK
to return to TMView.
The newly downloaded MapSpace with all associated datasets and
will appear in the MapSpace list in the MapSpace Manager.
If not, go to MapSpace > Browse to the directory where
the new MapSpace was downloaded and Open the new MapSpace.
In the MapSpace Manager, highlight the new MapSpace name
and click Draw Map.
5.2 Downloading Datasets from the ECAI Clearinghouse
For direction on downloading datasets from
the ECAI Clearinghouse, please refer to the Viewing Data
> TMView > MapSpace Manager > Adding Datasets
section of the TMView Help Tool.
5.3 Looking further at the MapSpace Manager
With MapSpaces and datasets loaded in the
MapSpace Manager, we can begin to look at the tabs
on this page to get more detail about the data we have.
Overview Tab
Graphically shows the geographic extent of each of the
MapSpaces listed in the MapSpace Manager window.
The extents of each MapSpace are enclosed by a bounding
box.
MapSpace Tab
Allows you to enter metadata about a MapSpace.
Extent Tab
The Extent tab control a variety of functions
Datset Tab
Allows you to review the metadata for a dataset.
Layer
Allows you to control the display of the selected layer.
