OVERVIEW

GEODE uses ActiveX component technology to provide the GIS functionality of the query builder (GEODE MapViewer). The control has been designed to emulate popular GIS packages, therefore, those familiar with GIS should find the control to be straightforward. GEODE MapViewer and its associated data resides on the client machine and must be installed prior to GEODE being used.

VIEW SEARCH RESULTS

Clicking the 'Results' button or 'Submit' on the Query Builder will take one to the Search Results window. This page diplays the title and abstract for each data set that meets the search specifications; (see a sample results display.). It also provides the ability to view the full metadata record or place a file into the backpack.

Clicking a file's 'MetaData' button will allow one to view the entire FGDC Standard metadata record.

Clicking a file's 'Select' button will add it to the backpack. The button will be 'grayed-out' if the file is already in the backpack.

VIEW METADATA and DATA IMAGE

Clicking the 'Metadata' button next to a file on either the View Results or Backpack pages will display the FGDC Standard metadata record for that file.

The Geode MetaData Report allows the user to view an entire metadata record; (see a sample report). The special navigation bar at the top allows navigation to any of the seven FGDC sections.

Files are added to the backpack on the 'Search Results' page.

Next to each data set in the backpack are two buttons. The first will allow one to view the meatdata record for that file. The second allows one to remove the file from the backpack.

Clicking the 'Clear' button will remove all files from the backpack. The 'Submit' button will allow one to submit the backpack to the download process.

DOWNLOADING AND USING GEODE DATA

Downloading a set of files from GEODE requires two separate steps.

1. On the 'Backpack' page, one must confirm that the files displayed are correct and then click the 'Submit' button. Geode will then package the backpack for download. Depending on the number of files, this can take several minutes to complete. When finished, Geode will display the filename and size of the file package. This file name is required to retrieve the file from the library.

2. Each campus will have differing download procedures. Details may be obtained from the campus Geode Coordinator.

On the 'Welcome' screen, clicking the 'Download' button will display a screen that allows one to enter the filename provided by Geode. Clicking on 'Submit' will initiate the downloading of the file to a local machine. When prompted, one clicks 'Save to disk' and enters an appropriate path and filename.

Geode data is provided in ESRI Shapefile format for feature data sets and in BIL format for grids. Each data set will be placed in a separate folder along with its matching metadata record.
