•Open source•Best of all it is FREE!•http://www.gimp.org
•Most GIS systems already use ArcGIS
Creating Image Layers
2013 Indiana GIS Day & Conference
Tools used:
• Add Alpha Channel• Erase/Cut• Rotate 90 deg.• Rotate Tool• Scale Tool• Perspective Tool• Merge Tool
Creating Image Layers
Two Methods:
2013 Indiana GIS Day & Conference
• Rectangular Clipped Images
• Custom Shape Clipped Images
• Method Wayne Co used
• Works well with various software- Map Guide, AutoCad, Microstation Etc
• Complex in creating• Works well within the
ArcGIS world of raster mosaic datasets
• Rectangular Clipped Images
Preplanning• Would like to
keep clipped edges in road right of ways
• Determine which map pages to merge to create good North South break lines
