First developed by Tim Berners-Lee in 1990, HTML is short for HyperText Markup Language. HTML is used to create electronic documents (called pages) that are displayed on the World Wide Web. Each page contains a series of connections to other pages called hyperlinks.

Deep learning for large scale biodiversity monitoringGreenapps&web

Conservation Metrics, Inc.
Healthy ecosystems with intact biodiversity provide human societies with valuable services such as clean air and water, storm protection, tourism, medicine, food, and cultural resources. Protecting this natural capital is one of the great challenges of our era. Species extinction and ecological degradation steadily continues despite conservation funding of roughly U.S. $20 billion per year worldwide. Measurements of conservation outcomes are often uninformative, hindering iterative improvements and innovation in the field. There is cause for optimism, however, as recent technological advances in sensor networks, big data processing, and machine intelligence can provide affordable and effective measures of conservation outcomes. We present several working case studies using our system, which employs deep learning to empower biologists to analyze petabytes of sensor data from a network of remote microphones and cameras. This system, which is being used to monitor endangered species and ecosystems around the globe, has enabled an order of magnitude improvement in the cost effectiveness of such projects. This approach can be expanded to encompass a greater variety of sensor sources, such as drones, to monitor animal populations, habitat quality, and to actively deter wildlife from hazardous structures. We present a strategic vision for how data-driven approaches to conservation can drive iterative improvements through better information and outcomes-based funding mechanisms, ultimately enabling increasing returns on biodiversity investments.

end application will do required processing on
that data in whatever way you like.

drop-down menus, radio buttons, checkboxes,

• This is also a form of single-line text input
controls are created using an <input> element
whose type attribute has a value of password.
• <input type=“password“>
7. Multiple-Line Text Input Control

more than one line of text, you should create a
multiple-line text input control using the
<textarea> element
Attributes for <textarea> tag.
• name: The name of the control. This is used in
the name/value pair that is sent to the server.

is required to be selected.
Radiobox attributes:

sent to the server if this option is selected.
14. <!DOCTYPE html>
<html>
<body>
<form action="">
<input type="radio" name="sex" value="male">Male<br>
<input type="radio" name="sex" value="female">Female
</form>
<p><b>Note:</b> When a user clicks on a radio-button, it
becomes checked, and all other radio-buttons with
equal name become unchecked.</p>
</body>
</html>
15. HTML Forms - Select box Control
• Drop Down Box is used when we have many
options available to be selected but only one will

17. HTML Forms - File Select Boxes
• If you want to allow a user to upload a file to
your web site from his computer, you will
need to use a file upload box, also known as a
file select box. This is also created using the
<input type=“file”> element.
