Help (Java-based Form)
This form is used for sending user defined values for selection from
Seismological Catalog. Client software consists of Java-based request form
as well as simple HTML form. While Java-based form provides more
convenience, especially if user needs to define complicated area form, it
can't work under old WWW browsers which do not support Java. In this case
user can use HTML form, which, being less convenient, provide the same
level of functionality.
- Select map orientation:
Map1 or Map2.
- Define form of area for search.
- Rectangle.
Move cursor to one of proposed corners of rectangle, press mouse key,
draw mouse to the opposite corner, then release it. You can start from any
of the corners.
- Polygon. Move mouse to the first
corner (node) of proposed polygon, click mouse, then move it to the next
(incident) node, again click, and so on. Press together two mouse buttons
to close polygon.
By default maximum number of polygon nodes is 50.
- Circle. Move cursor to the center
of circle, press mouse key, draw mouse along the radius to the circle and
press mouse key.
Note that the circle is not actually round one because of map projection used.
- Coordinates. In this case you
don't need to draw anything on the map. Change coordinate fields of the
form if you need.
- Fill in text fields of the forms for time
, magnitude and
depth intervals.
When you filling in text fields of the form applet prevents you from entering
non-digit characters or interval delimiter,
if it is not applicable. In case of entering values, which are out of the
default range, a warning message appears.
- Redrawing and changing. To redraw
figure and change it or to change time, magnitude, and depth values press
"RESET" button.
- Submit. When your request is ready
press "SUBMIT" button to submit entered
data to the server.
