<DIV>Hello.<BR><BR> Currently, PostGIS doesn't support dealing with images.
So, I used<BR>PostGIS's Geometry Type as a refrence or retrieval for exaternal
aerila<BR>photo in the following manner for outputing SVG instances by
PHP.<BR><BR><BR>
Table "airphoto"<BR> Attribute |

precision |<BR> b |
double precision
|<BR> c | double
precision |<BR> d |
double precision
|<BR> e | double
precision |<BR> f |
double precision |<BR><BR> where "geo_value" is polygons which is
extent of images, "urlname" is<BR>URL of images, "ox" and "oy" are
origin coordinate in pixel, "width"<BR>and "height" are literally images' ones
in pixel, "a" - "f" are<BR>parameters of affine tranformation for images
deriving from world files<BR><BR> I show followin'
examples.<BR><BR> geoid
