Distributed processing for Orthophoto productionDave Loescher & Jeff Hyatt

TrendsTrends

Larger orthophoto projects and shorter project times– Reduce project time

Speed up tasks that are processor intensive

– Distributed Processing

– Reduce costs

Automate tasks where possible

Improve QA/QC processes, less rework

– Provide project management tools

OrthoPro Seam editing enhancementsOrthoPro Seam editing enhancements

Improved seams editing

– Red/Blue Image display tool for drawing seams

– User can see where the overlapping images match and edit lines to pass through these areas

– Up to 20% productivity gain for seam editing
