10013: Layer uses dynamic orthorectification

You have a raster map layer with orthorectification being performed at draw time. The processing time required for the dynamic orthorectification will cause the layer to be drawn more slowly. Raster layers that have already been orthorectified and saved as a dataset will result in better drawing performance than deriving the orthophoto on the fly.

ArcGIS provides a series of tools for improving the display of imagery, including using orthorectification for more accurate raster display. Orthorectification is the process of stretching and warping the image to match the spatial accuracy of a map by considering location, elevation, and sensor information. Variations in scale and displacements that occur during initial image collection (for example, due to relief) are eliminated or reduced by the orthorectification process. The product of this process is often referred to as an orthophoto.

There are some valid reasons for computing orthorectification on the fly. One is that you may have a new, more accurate (and higher resolution) DEM that can help to improve the locational accuracy of your orthophoto display.

You have two approaches that you can use to apply orthorectification:

For use in a Web map, your Web map design will need to change to use the ArcGIS Server Image extension. You would remove image layers from your ArcMap document. In your Web application, you would mash up your resulting optimized map service with the image service.
