<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">My interactive mapping application is currently using Shapefiles to store the contour lines. At 1.5 GB the Shapefiles are rather large. Instead I am considering using a File Geodatabase which will only take up about 500 MB.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Is there a significant performance loss between Shapefiles and File Geodatabases? And are there any performance tips and tricks for using File Geodatabases?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks<o:p></o:p></p>
