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 Mapping on E-Flora BC page.
If you have any questions about our maps, please contact us.
To view the layers and legends and background data
When you view the full-size interactive map, two data/information boxes should appear on the right-hand side of the map. These contain 1) the layers and legends used on the map and 2) a box that allows you to display the data associated with each distribution dot (click on a distribution dot to call up the data).
If the two information boxes are not opened by default by your browser, then you will need to open them. To do this go to the icons on the top left of the map. Cursor over them until you find one labeled as 'Layers and Legends' and one labeled as 'View Record Details' (the 2nd and 3rd icons in the figure below). Click on these and the boxes will open.
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 using 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). The data will be displayed in the 'View Record Details' box on the right hand side of the map. 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. The dots should be displayed to the left of the layer name in the Layers and Legends window (see below).
What the ICONS and symbols on the maps mean.
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.
Located along the top left edge of the map are 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.
: 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
: 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).
: This button zooms you out to the full extent of the map,
which is the entire province.
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
Along the top of the map is where you can find additional tools for getting more details about the records shown on
the map, and for redisplaying the Layers and Legends window. You can minimize a tool with the - button located in the upper right of the window.
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).
Base Map: This base map includes roads, political
boundaries, cities, major rivers and lakes, and some protected areas.
Base Map: This base map has satellite imagery for the world
at a resolution of 15m worldwide, and 1m in the USA.
Topography 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).
