This page provides helpful information about how to use the GeoPortal. You can use the sidebar links to navigate to what you want to know.

The GeoPortal provides access to data sets and a map editing application allows users to browse existing maps and contribute their own.

Browsing Data

The Spatial Data tab allows you to browse data uploaded to this GeoPortal.

All data can be downloaded in a variety of formats, for use in other applications.

Browsing Maps

The GeoPortal allows users to create and share maps with one another.

The Maps tab is a gateway to map exploration on GeoPortal. From here you can search for a map or create a map, which will open the Map Composer.

Google Earth Mode

Any map viewed in the interactive map editor can be seen in 3D mode with the Google Earth plugin. To switch to 3D mode select the Google Earth globe logo, the rightmost button on top toolbar. If you do not have the Google Earth plugin installed you will be prompted to install it.

Creating a Map

To create a new map go to the Contributed Maps tab and click the create your own map link.

This will take you to the Map Composer with a base layer loaded.

To add data layers from the GeoPortal click on the green plus button located below the layers tab on the left hand side of the screen. This will open a dialog listing all the layers available on the GeoPortal.

To add layers to your map select them and hit the Add Layers button. When finished you may hit Done to close the dialog and go back to the map.

Reordering and Removing Layers

Change the display order of the layers listed in the data tab by simply dragging and dropping their names. The order in the map will be updated to reflect that. To turn a layer's visibility off simply uncheck it, and to remove it entirely select it and hit the red minus button.

Updating a Map

Any map available can serve as a starting point for a new map.

  1. Open the map in the Map Composer.
  2. Add and remove layers as you like.
  3. Pan and zoom to highlight the area of interest.
  4. IMPORTANT: Update the title, abstract, contact info and tags to reflect the new map.
  5. Save the map.
