Creating Image Layers
Software used:• GIMP (manipulating images)
• ArcGIS Desktop (Rectification and clipping)
2013 Indiana GIS Day & Conference
•Open source•Best of all it is FREE!•http://www.gimp.org
•Most GIS systems already use ArcGIS
![Page 12: A New View to the Sanborn Map Collection of Wayne County, Indiana](https://reader035.fdocuments.in/reader035/viewer/2022070422/56816552550346895dd7c9d2/html5/thumbnails/12.jpg)
Creating Image Layers
2013 Indiana GIS Day & Conference
Tools used:

Creating Image LayersTwo 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

Rectangular Clipped Images
2013 Indiana GIS Day & Conference
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

Rectangular Clipped Images
2013 Indiana GIS Day & Conference
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
