MarineBIOS Data Viewer User Guide
Upon web map viewer startup, a welcome screen provides you with information about the viewer, possible use restrictions and links to additional information.
Project Banner
In the top left corner of the viewer is a banner area that includes the CDFW logo and the project banner.
Clicking on the CDFW logo in the
banner will take you to the California Department of Fish and Wildlife homepage.
Clicking on the
Marine logo in the banner will take you to the Marine Region homepage.
Table of Contents (TOC) - In the left side panel is the Table of Contents. The
Table of Contents lists the data layers that are available to the particular
viewer by default and the available basemaps. The TOC also provides other map
content related functionality, such as displaying the metadata and symbology
for your data layers.
If the TOC Panel is collapsed it can be
made visible again by clicking on one of the tabs on the toolbar such as the Layers tab or the Basemaps tab. If it is open and you wish to close it you can do so by clicking
on the close (x) button on the upper-right corner of the panel. You can switch
the contents of the panel by clicking the different tabs on the
toolbar. Clicking on the tab that is already 'on' will close the panel.
The
Table of Contents panel may include the following contents:
- Layers
- This tab is active by default
in the TOC panel. It displays a list of all the current map content with
the exception of the background map.
- To draw a data layer, simply check on the small box to
the left of the name of the data layer in the Table of Contents. We have
some very large and complex datasets in MarineBIOS, so we do not draw
them automatically when they are loaded into the map. This gives you a
chance to zoom in to your area of interest first improving both the
performance of the viewer and the legibility of the data.
- Click on the layer name in the Layers tab of the Table
of Contents to activate the layer
or select it as the current Active Layer. This makes the layer available
for use with the various tools in MarineBIOS. You will see a pink box
appear around the layer indicating that it is active and the name of the
layer will show in the Active Layer display.
- You can view the metadata document for the layer by
clicking on the Info
(i)
button to right of the layer name.
- The Go
button will allow you to quickly zoom the map to the full spatial extent
of the Active Layer.
- A symbology legend is available for each data layer in
the Layer tab. Click on the
+ to the left of the Layer name
and check box and a drop-down legend will appear below the layer name
showing each type of symbol used to display that dataset in the map.
Feature symbology is not editable in MarineBIOS at this time.
· Graphics and Selections - This section lists any graphics layers that you have created in your map, such as map labels, as well as any selections that you have created while working with the layers and tools.
- Reference
Layers -
This section lists the general purpose map layers that are provided for
geographic reference. These include layers for cities, place names, county
boundaries, USGS Quads, and US Township/Range/Sections. By default, the Point Info tool uses
these layers to display general location information about a point that
you clicks on the map.
- Basemaps
- You can change the background
map to any map available under the Basemap tab
in the Table of Contents on the left side of the viewer window. Choices
include imagery, street maps, topographic maps and several years of NAIP
imagery, among other options. The default basemap
that is loaded when the viewer opens is the ESRI Oceans Map.
Table – Between the Layers tab and the Basemaps tab in the Table of Contents you will find the Table tab.
This tab will
open and close the collapsible data panel along the bottom border of the
viewer. When you search for a layer feature by using the Search Active Layer
Quick Tool or select features using the Select tool, valid results will be
displayed in a table format in this Table panel. No more than 300 records will
be displayed in the Table panel.
· Active Layer Display - Along the top of the Table of Contents panel and just below
the Layers tab is a small display showing the currently selected Active Layer.
Tools that
interact with the data layers will work only on the Active Layer. To make a
layer active you simply click on the layer title. You will see a pink box appear
around the layer showing that it is active and the name of the layer will show
in the Active Layer display.
Map Canvas
In the center spanning the most of the page height and width is the map canvas. This is where map layer data will be displayed where you can interact with the data by using the tools provided. Panels that run along the side of the viewer (side panels or sidebars) can be closed to reveal a large map area.
- Zoom
Slider- Zoom in
and out of the map view by clicking on the bar or hold mouse down and drag
the slider up or down the bar.
- Scale
Bar - The map scale bar along the
bottom right of the map next to the Esri logo
shows the current map scale in miles distance.
- Overview
Map - The overview map lies on the
bottom left corner of the Map Canvas and offers a broader overview of the
current map view extent. Upon first opening the map viewer, the Overview
map may be hidden. Click on the little arrow at the lower left corner
to expand it. The overview map may be hidden by the Table panel when the
Table panel is open.
MarineBIOS Tools
All of the tools from the previous version of the MarineBIOS viewer are still available in the new version. They have been arranged into the three drop-down menus that you see at the top of the viewer.
To use a tool in MarineBIOS, you must first select the layer that you want to use the tool on in the Layers tab of the Table of Contents on the left side panel of the viewer, making it the Active Layer. Once you have an Active Layer to work with you can select and use your tool. The current Active Layer is indicated by a solid pink box around the layer name in the Layers list.
Quick Tools Menu
On the
top center of the viewer, next to the logo area is the Quick Tools menu. Here
you will find tools that interact with the text box to the right of the menu to
perform various tasks. Results may be displayed in an automatic drop-down
selection list directly below the input text box. Click on the Quick Tools
drop-down to see a list of available tools.
- Add
Data: KML Tool – This tool allows you to add a publicly
accessible dataset that is formatted as KML (Keyhole Markup Language) or
KMZ (zipped or compressed KML files) to your BIOS session. Select the Add
Data: KML tool and then enter the URL into the Quick Tool menu input box
and press the Enter key on your keyboard.
- Add
Map Service Tool –
This tool allows you to add any publicly accessible ad hoc map data source
in the format of an ArcGIS Server REST Map Service. Select the Add Map
Service tool, enter the URL into the Quick Tool menu input box and press
the Enter key on your keyboard. The Map Service will be added to the
Layers tab in the Table of Contents and will draw in the Map Canvas.
- NOTE: Some functionality will be limited if the map service coordinate system / spatial reference is not in Web Mercator (wkid=102100, conforming to ArcGIS.com/Bing/Google Maps).
- Select
from List (of Feature Names)
Tool - This tool queries the
current active layer for a list of feature names and returns them as a
list. If the immediate result for the entire feature layer is less than
500 features, then all of the names are listed in a drop-down list under
the quick text box.
You can also type something directly into the quick input box and the list will be dynamically filtered to match the search term that you have entered. Click on a feature in the list and the map will zoom to it and display the corresponding attribute information for that feature in a pop-up window in the Map Canvas.
- Search
Active Layer Tool
– This tool allows you to
search for features in the current Active Layer by attribute values.
First you must activate a feature layer and choose the Search Active Layer tool from the Quick Tools menu. Then type in a search term in the text box and press the Enter key on your keyboard to run the tool. You can type in a partial search term if you are not certain of the full term. For example a search of the California Marine Protected Areas dataset for “reserve” returns all records with a value of “State Marine Reserve”.
A record for each of the features selected will be listed in the Table panel along the bottom of the viewer. The corresponding features will be highlighted yellow in the Map Canvas. Click on the Go button in the ZoomTo field to zoom to a particular feature listed in the table.
- Locate
Address Tool - Type a
full or partial street address, zip code, city or place name into the
search box and press the Enter key on your keyboard. A geocoding service
will locate the address entered on the map and the map will zoom to the
location of the closest match results.
