Information Technology/Data Sharing<br />

Futuristic predictions say that by 2030, video calling will be pervasive, generating 400 exabytes of<br />

data - the equivalent of 20 million Libraries of Congress. The phone, web, email, pho<strong>to</strong>s, and<br />

music will explode <strong>to</strong> generate 50 exabytes of data. With that, improved Wireless<br />

Telecommunications Services will be observed such as: Video distribution and messaging;<br />

innovative service offerings; packages tailored <strong>to</strong> niche groups regionally; and instantaneous<br />

(19, 20 and 21)<br />

transmission of large amounts of data. Such overwhelming data availability will<br />

challenge agencies capability of handling and making good use of such amount of data.<br />

Information sharing across agencies is a key fac<strong>to</strong>r <strong>to</strong> overcome this issue, promoting a strong<br />

basis for collaboration and coordination in managing incidents.<br />

Today, one of the challenges in identifying operational performance benefits is generally related <strong>to</strong><br />

a lack of baseline performance data from which <strong>to</strong> measure. With an improved data quality and<br />

amount, electronic data collection (particularly in recording the incident start and s<strong>to</strong>p times) will<br />
