Pima Image Comparison Tool - PICT
The Pima Image Comparison Tool (PICT) is an orthophoto and aerial image viewer.
PICT can display images side-by-side or overlaid
to compare different image types and image years.
See the overview for more explanation.
We hope to add more features to PICT at a later date.
PICT is supported only on the Windows Internet Explorer web browser at this time.
The first time you open PICT, you may be prompted to install the required ECW Plugin.
See ECW Plugin for more.
Results are unpredictable with other web browsers.
- Read the Disclaimer and Pima Image Comparison Tool Help.

For best results maximize (enlarge) your web browser window
before opening the PICT viewer.
If you resize the PICT viewer window, hit your browser's Refresh button
to restart PICT for the new window size.
The viewer can't be resized after you open it.
The "Spliced Views" mode will have a gap at the seam if the browser window is
small and the window has a horizontal scroll bar.
It would be interesting to know how PICT helps you.
What makes it better than looking at imagery using MapGuide or other tools?
What PICT options and image choices are particularly interesting or useful?
