The Checklist Entry application
lets you enter and edit a list of plants that you
are looking for -- and/or have actually found --
at a particular location.
To use the application, you need to be registered
as a contributor.
To enter a new record, press the button.
Click on the map to indicate the location .
Enter an observation date in the form 2014-12-31,
or press the today link, or press the calendar link
to choose the date from a calendar.
Other fields are explained on the right.
To add plants to your checklist, press
and then press
Add one plant name.
Type in the first few letters of the scientific name of the plant.
After three letters, a list of matching genera will appear.
You can choose the genus from the list, and then type in a few letters
of the species, or just keep typing.
When you have the right plant name, press the button,
and the plant will appear in the table below.
(It is also possible to paste in a list of plants from
another document; see this
Note that in the table of plants, the last column
is called COUNT, meaning how many of this particular
plant were observed in the search area.
When a plant is first entered,
the value of the COUNT field is ? (unknown).
To change the value, click on the COUNT cell for the plant,
and either type in a number, or choose a range from the drop down.
The following are special values of COUNT:
?: unknown; not yet found.
0: no plants; absence.
1: exactly 1 plant.
1+: at least 1 plant.
By means of the COUNT field, a checklist can function as a simple survey
of the search area. That is, it can indicate that the observers
looked for a plant and did not find it (0, absence),
or that the observers have yet to either confirm or deny the
presence of the plant in the area (?, unknown).
By means of a specific count or a count range (11 - 50)
it can also indicate the relative abundance of a particular plant
in the area.
Line or Polygon:
Press SHAPE at the top to
enter a line or polygon describing the search area.
The shape drawing panel opens in the top
right of the page. Choose polygon or line, then press .
At this point, each click on the map becomes a vertex of
the shape you are drawing. (Dragging the map has no effect on the shape.)
Press when you are done.
Press if you need to add more vertices,
or delete vertices, or move vertices.
Once you have defined a polygon,
press calculate area
(next to Area Size) to calculate the area of the polygon
in any of several units (square meters, acres, etc.).
The area value is obtained from the Google Maps Geometry API.
Press ADD / VIEW PHOTOS
to attach a photo "voucher" to your checklist record,
either by 1. uploading a photo from your computer, or 2.
pasting in the URL of your photo already on the web.
A description of the process is in
FAQ - About Contributing Observations.
The elevation in meters of the point you selected on the map

The elevation value is obtained from the Google Maps Elevation API.
