<p class="MsoNormal">Hello,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">In the past I prepared my air photos for MapServer by converting them into GeoTiff and creating compressed jpeg overviews. I would like to double check if this is still a recommended method to prepare air photos that are fast, have a decent
amount of quality, and are not terribly large. If anyone has any comments on how I should prepare air photos for MapServer and possibly ArcGIS or QGIS let me know.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Here is what I used in the past, which seems to work good:<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I will be provided an ECW file, Mr Sid file, and I will be given the choice of getting either 775 individual jpg or tiff tiles.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
