Creating Image Layers

Software used:• GIMP (manipulating images)

• ArcGIS Desktop (Rectification and clipping)

•Open source•Best of all it is FREE!•http://www.gimp.org

•Most GIS systems already use ArcGIS

Creating Image Layers

Tools used:

• Add Alpha Channel• Erase/Cut• Rotate 90 deg.• Rotate Tool• Scale Tool• Perspective Tool• Merge Tool

Creating Image LayersTwo Methods:

• 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

Rectangular Clipped Images

Create Base Map in ArcGIS

• Use Features found on the Sanborn Map• Road R/W• Parcel Lines

• Set scale to equal Sanborn Map• Most maps 1”=50’

• Export base map for use in GIMP• Tiff or Jpg

Add map pages and base map to GIMP• Rectify against base map• Rotate, Stretch, Erase• Cut and paste data that might get lost in

the clipping process

Ready for Georeferencing
