Some international spatial coordinate formats and international date formats are not recognized by default when they occur in the input text. However, the dates in the input text above fall outside the default date range. Once the locations of the three earthquakes have been extracted from the input text, the output feature class appears in the Contents pane, and the points are visible in the active map.īy default, any dates found in the input text that are within a relatively recent time period are also extracted and recorded in the attribute table of the output feature class. The third, measuring 8.6, occurred on March 9th, 1957, near the Andreanof Islands ( 51.50°N,đ75.63°W). The second largest Alaskan earthquake, measuring 8.7, occurred on February 4th, 1965, near the Rat Islands ( 51.25°N,đ78.72☎). The largest, measuring 9.2 on the Richter scale, occurred in the Prince William Sound ( 60.91°N,đ47.34°W) on March 28th, 1964. This interaction has accounted for three of the largest recorded earthquakes in history. The tectonics of the region are dominated by the interaction of the Pacific and North American plates.
Input textĪlaska averages 100 earthquakes a day. If you are reviewing news articles about earthquakes in Alaska and want to see each location that is mentioned in an article on a map, the sample input text below can be copied and pasted directly into the pane. The capabilities provided in the Extract Locations pane are also available using the Extract Locations From Document and Extract Locations From Text geoprocessing tools. The Extract Locations pane does not automatically recognize text that represents an address as a spatial location and, therefore, cannot use a locator to produce a point representing that location. Dates and keywords associated with the location can also be extracted. Text around the spatial location is extracted from the original document and stored in attributes to provide context for the location. You can also drag text from an email or a web page onto the pane to be analyzed.Įach point in the output feature class has content in the attribute table indicating the file in which the spatial location was found. The Extract Locations pane can process many folders and files at a time, or scan an entire disk.

Unstructured data is any text or document including, but not limited to, web pages, reports, emails, and social media content. The ArcGIS LocateXT extension allows you to use the Extract Locations pane to search unstructured data for spatial locations and generate point features representing those locations.
