    Default Raster with good spatial resolution to kml and then put it in google

    Hi

    I have an aerial photo with a really good spatial resolution. I'm trying to select a specific place in this photo, then this photo convert to KML so I can use it in Google. The segment that I cut is in a small scale and then convert this segment to kml, but when I zoom this segment in Google it has not the same quality, the resolution is bad. Is it possible that when I cut a segment in a small scale, when I zoom this segment in a larger scale the quality of the Photo persist? Or I have to do a cache of this segment and make a service in ArcGIS Server?
    Hope anyone can help me

    Regards,

    Diego

    Hi Diego,

    I don't know if you've figured it out by now but I had the same problem. Making the resolution better doesn't have much to do with the scale but more with the image size and the dpi you choose. I also had a georeferenced aerial photo and what I did was play with the image size and dpi. A good DPI is 300 or more (i chose 600) and for my image size I chose 12000 and the default value was 1024 so try to play with those values.

    Hope it works, I see it's been a long time since you asked this question.

    Sincerely

    Santiago
