This is due to the many manual steps still present in many GIS publishing and consuming workflows, which preclude more frequent schedules. Thus, there is not as much of a rush to do their updates, and the need is not as urgent as the proposed film would show. Randall claims the urgency was exaggerated for dramatic effect, humorously disregarding the fact that neither version of this scene would be dramatic to a typical moviegoer.&lt;/div&gt;&lt;/td&gt;&lt;td class='diff-marker'&gt;&amp;#160;&lt;/td&gt;&lt;td style=&quot;background-color: #f9f9f9; color: #333333; font-size: 88%; border-style: solid; border-width: 1px 1px 1px 4px; border-radius: 0.33em; border-color: #e6e6e6; vertical-align: top; white-space: pre-wrap;&quot;&gt;&lt;div&gt;The title text refers to the fact that most GIS datasets are not published in &amp;quot;real time&amp;quot;, but, rather in updates every 3 months or less often.
