Jacob Coble is an Application Developer for Tallahassee-Leon County GIS

His tasks range from data analysis to making custom tools, applications and models. On the programming end of things, he started out scripting AMLs, and then made a successful MapObjects mobile application. Now much of his focus in on ArcGIS for the desktop. He creates custom tools and automates tasks using Python or .NET/ArcObjects. He has done projects involving processing aerial imagery (anything from historical aerial imagery to satellite imagery), using LiDAR data and customizing a GeoPortal Web application.

Presentation

Processing Satellite Ortho Imagery Using ArcGIS and PhotoShop

This will demonstrate how to use Photoshop together with ArcGIS to convert 16-bit, 8-band satellite ortho imagery into highly usable, color-adjusted RGB and CIR images. Why would one want to use Photoshop to make color adjustments to the imagery? Photoshop will allow you to bring out the very best from the imagery. It is cumbersome to import a 16-bit 8-band image into ArcMap and adjust the symbology for an RGB view of the image. Also, the quality of the 8-band images viewed straight from ArcMap will probably not be very good and the colors will probably not be accurately represented. You can use Photoshop to make very good color-adjusted RGB and CIR versions of the images.You can deploy these images and use them in ArcGIS just like you would use any other aerial images.

I will demonstrate several image conversion and color adjustment processes in ArcGIS and Photoshop. I will take some sample images, process them and show the results in ArcMap. Best of all, these processes can be automated both in ArcGIS and Photoshop! You might be surprised at what you can do with imagery using Photoshop together with ArcGIS.

This is not really meant to be an introductory Photoshop class. If you are not that familiar with Photoshop you might still find it helpful to see how programs like Photoshop can be used in conjunction with GIS. If you are experienced with Photoshop, this might give you some specific ideas to try.
