Because these two ArcView 3.x extensions have similar functions, they are offered here together in one download. Extension descriptions are provided below.
Image-Tools (v2.6)
This extension provides various image-related utilities, including specific features for use with single-band images (such as topographic map scans, DRG, DOQ, NOAA chart, and other pseudocolor/color-indexed products) as well as multi-band images (such as true color airphotos).
The current Image-Tools extension provides these options:
* Side by side single-band image viewing (edgematching - making overlap transparent).
* Isolate particular single-band image colors.
* Toggle single-band image colors to transparent.
* Display single-band image colors in grayscale.
* Restore default image colors.
* Display transparent single-band image colors as white.
* Save a colormap file for the active single-band image (including transparent colors).
* Load a colormap file for single-band images (including transparent colors).
* Make all images visible (or all single-band images or all multi-band images).
* Activate (highlight) all images (or all single-band images or all multi-band images).
* Build an image catalog from images in the view.
* Build an image catalog from images stored on disk.
* Export views to georeferenced JPEG images (with quality and DPI settings).
* Convert active single-band images to grids (transfers image colors to grid theme).
* Note: Spatial Analyst is NOT REQUIRED to use the core features of the extension.
Once downloaded and unzipped, please read the file "imgtools.txt" for further information. Check back for future updates.
DRG-Tools (v3.7)
This extension provides specific utilities for use with most digital raster graphic (DRG) images. A DRG is a scanned image of a USGS standard series topographic map. For more information about DRG products and ordering, visit the DRG Program home page at: http://topomaps.usgs.gov/drg/
The current DRG-Tools extension provides these options:
* Side by side DRG image viewing (edgematching - making the collar transparent).
* Isolate particular DRG image features, such as contours or hydrography.
* Toggle DRG image colors to/from transparent.
* Display DRG image colors in grayscale.
* Restore default DRG image colors.
* Display transparent DRG colors as white.
* Save a colormap file for the active DRG image (including transparent colors).
* Load a colormap file for DRG images (including transparent colors).
* Make all DRG images visible.
* Activate (highlight) all DRG images.
* Build an image catalog from DRG images in the view.
* Convert active DRG images to grids (transfers DRG colors to grid theme).
* Note: Spatial Analyst is NOT REQUIRED to use the core features of the extension.
An archive of DRG-related *.clr, *.avl, and *.avp files is also included....
