Slide show of information on DOQ file formats

 DOQQ-to-GeoTIFF conversion doq2geotiff.exe [binary] 370688 bytes converts a native formatted DOQQ image to GeoTIFF format in either NAD27 or NAD83. Operates under a DOS window.

Postscript Printer File of instructions for loading USGS 1:12,000-scale DOQQ image files.
README and doqhead.tar [binary] Unix:tar file (606208 bytes) creates Arc/Info BIL header for USGS 1:12,000-scale DOQQ files ... both single and multiple band (CIR). These files are also available as a PKZip file (116135 bytes), but contains source code for C-programs only.

See README file for explanation of NT tools
Windows NT: create DOQ header for older non-keyword-header B&W (BIL) DOQ
Windows NT: convert DOQQ to BIP format for older non-keyword-header Color (BIP) DOQs
Windows NT: create DOQ header for all keyword-header DOQs, both B&W (BIL) and Color (BIP)

New Keyword Header format for DOQQs:README and Unix:C-script for creating Arc/Info BIL headers for multiple USGS 1:12,000-scale DOQQ files.

New Keyword Header format for DOQQs:standalone Arc/Info AML for creating Arc/Info BIL header for single USGS 1:12,000-scale DOQQ file... the basics. For AML/Menu interface, see doqhead.tar or PKZip file

README and doq_drg_merge.tar [binary] version 2.1 as a Unix:tar file (163840 bytes) merging of USGS digital raster graphic (DRG) and digital orthophotoquad (DOQ) images developed at Mid-Continent Mapping Center in Rolla, Missouri. See a GIF version (254798 bytes) of the results.

elev2hillsh.aml creates a hillshade grid from an input elevation grid, with options to rotate and clip output.

README and elevation.tar [binary] Unix:tar file (147456 bytes) menu-driven toolkit for converting USGS DEM files to Arc Grids, creates basic Hillshading and optional 3-D perspective views for either plotter or screen

gridmosaic.aml creates a large mosaicked grid of smaller contiguous grids.

project_headers.aml reprojects all Arc/Info image header (.hdr) files in a directory from one projection system to another. See code for altering the projection parameters, currently UTM/Zone10/NAD83 to UTM/Zone10/NAD27.

image2grid.aml converts an ARC/INFO-supported image into a Grid.

img_clip.aml creates a new sub-image clipped from an input image, based on an interactive extent or a clip coverage.

img_convert.aml converts a single image or a bunch of wildcarded images to the specified output image format.

img_plot.aml and img_plot.menu ( must be bundled) create a plotfile in the specified output format (GRA, EPS, CGM) of either the entire input image or of an image subset.

img_plot_orig.aml creates a plotfile in the specified output format (GRA,EPS,CGM) from the input image(s) or grids. (This previous version of img_plot.aml allows the use of wildcards (*), where the new version does not.)

README and slope.tar [binary] Unix:tar file (131072 bytes) creates a raw slope grid and a reclassified slope range grid from an existing elevation grid. This tool also allows plotting of the slope grids.
