*** CROSS-POSTED ***<br><br>
Next <font color="#FF0000">Tuesday, July 20, from 9:00-10:00am in the CCL
Electronic Classroom</font>, Abe Parrish will present the sixth in this
Summer's series of REFreshers: <b> Geographic Information
Systems.<br><br>
</b>GIS is an information system that is designed to work with data
referenced by spatial or geographic coordinates. It refers to the
software, hardware, and procedures that process the information
requested. Once a map is digitized, it can be geo-coded. This means
that the GIS program "knows" each point's latitude and
longitude, so that one map can overlay another map and the same location
will be aligned in both. It is possible to use maps of various uses
(land use, topography, roads, human habitat, etc.) for a given area, and
multiple uses can be found by combining two or more layers. For example,
topography, land use, and rainfall pattern layers can be combined to find
areas that may be flooded.<br><br>
Please join us Tuesday morning, and learn more, including how this
technology is being used in teaching and research at Yale.<br><br>
