Using the Interactive Maps: Icons, Zoom Features and More
E-Flora BC's interactive web maps allow you to explore the distribution of a species and how it relates to the Biogeoclimatic Ecosystem Classification (BEC) zones, the climate, etc. of British Columbia. You can learn more about the data on our Mappng on E-Flora BC page. If you have any questions about our maps, please contact us.
General Information
The important thing about interactive maps is that you can do a lot with them. You can enlarge the maps or make them smaller by uzing the ZOOM feature. You can move the map around by using the PAN feature (hold your cursor down to move the map). You can retrieve data for a distribution dot by using the GET DATA feature (just click on a dot for the data to show up). You can change the base map using the SELECT A BASE MAP feature (you can switch from a regular map to a satellite map, for example). At any time, after you have made selections using our tools, you can return to the original map by hitting the REFRESH button on your computer or by using our FULL EXTENT tool, which does the same thing.
Our interactive maps show several categories of data, including distribution data and geographic data. For example, to view the data layers we use to show species distributions, go to the data layers box on the right, and click on the little box beside E-FLORA DATABASES. This opens a drop down list of databases we use. You can turn these database layers on and off by clicking on the associated checkbox. The other (geographic) data layers work the same way.
Our distribution dots are colour coded. Use the LEGEND icon in the data box (the little white box at the top of the data box) to open the legend and view what all the colours mean. Use the little folder next to it to close the legend and return to the list of databases.
What the ICONS and symbols on the maps mean.
The four large blue buttons (icons) located in the upper left of the map along the bottom of the banner -- "Navigate", "Tools", "Select a Basemap" and "Info" -- provide access to additional features (called 'tools'). The features / tools associated with each button
are explained in more detail below. The currently selected tool is
listed after "Current Action:" to the right of the species name; the default
tool when the map opens -- Get Data -- allows you to click on a data point and obtain information about that record. Shortcuts to most of the tools are also provided as mini-icons along the top of the banner.
Placing your mouse over an icon in the web map will, in many cases, result in a text pop up telling you what the tool does.
This is where you can access the tools
for navigating through the map. You can also drag the little arrow
on the scale bar in the upper-left edge of the map to zoom in or out. The scroll wheel
on your mouse will do the same thing.
Zoom
in: Click once to zoom in a little bit and recenter the map where
you clicked. If you want to zoom to a specific area, left-click &
hold the mouse button down while you drag a box with the mouse, and then release the
mouse button.
Zoom
out: This works the same as zoom in, but in reverse. You can click
on a point to zoom out a bit and recenter on that point, or drag a box
to zoom out by a different amount (drag a small box to zoom way out, or a
large box if you want to zoom out less).
Full
Extent: This button zooms you out to the full extent of the map,
which is the entire province.
Pan:
Left-click & hold the button down while you drag the mouse to pan
the map. You can also double-click to re-center the map, or, if you hold
down both shift and the left-mouse button and then draw a box with the mouse, it will work like the zoom in
tool.
This is where you can find additional tools for getting more details about the records shown on
the map, and for redisplaying the E-Flora Layers. You can minimize a tool with the 
button. You can also hide all open tools with
the 
button, and make them visible again with 
. Finally,
if you have several tools open you can scroll up and down the list with 
and 
. These buttons are located in the upper right of the map: 
Get Data: This tool allows you to click on a record and obtain the data associated with that record. To get the record's data, click the 
button and then
click on the record you want to see details about. You can continue to click on additional records and obtain their data. If you click on the results in the Get Data window the map will zoom into the record. To clear your selection, click
the 
button. Clicking on the 
on the top right of the Get Data window will bring you back to the initial window, clicking on 
will switch back to the Get Data results.
E-Flora
Layers: This folder icon opens the Table of Contents (that is, all layers available for this map set ) and allows you to choose which layer or layers you wish to display on the map. By default, the E-Flora Databases layer
is always visible and the other layers are turned off. To view other layers, imply click the check box 
next to a layer to turn it on 
or off .
Clicking on the small gray arrow next to a layer 
will 'open' the layer and show you the sublayers it contains. Click on the boxes of the sublayers you wish to view, and these will be displayed on the map.
You can close the table of
contents with the 
button, or minimize it with the button.
Legend:
Within the Table of Contents window you'll see this icon (on the top edge of the ToC window). Clicking on this icon will display a legend for the map that explains what the symbols for
each layer mean. Click on the folder icon immediately to the right of the legend icon to return to the list of E-Flora layers.
Print:
Print the map as it currently appears in your web browser.
This is
where you control what base map is visible on the web map. There are three
base maps available (other data listed under E-Flora layers can be displayed
on top of the base map).
Street
Base Map: This base map includes roads, political
boundaries, cities, major rivers and lakes, and some protected areas.
Satellite
Base Map: This base map has satellite imagery for the world
at a resolution of 15m worldwide, and 1m in the USA.
Shaded
Relief Base Map: This is a simple base map of shaded
topographic relief. It is intended for use between 1:40,000,000 and
1:70,000 as the data is not visible at the global scale or when zoomed
way in (the imagery will turn off).
