A collection of useful Arc/INFO and GIS datasets and scripts

This page lists datasets, aml scripts, and operational notes which have been assembled by members of this workgroup, for the use of other workgroup members. If there are questions about any item provided on this page, please refer to the contact information for that item. When a data set was originally obtained from an outside source, contact information for the source has also been provided.

Contents:

To submit a new item to this list send an email to the Hydro Administrator (hydro@hydro.washington.edu) which contains the following:

1. A heading for the item
2. A brief paragraph describing what the scripts do or datasets contain which will be added as text to the web page.
3. The full directory and file name of a tar file which contains all pertinate files, including a readme file which describes the contents of the tar file and how the provided data or scripts should be used.
4. If Arc/INFO files are provided they should be exported from Arc/INFO as .e00 files, and included in the tar file.
5. Information about who to contact from the workgroup if there are questions.
6. If the original data or scripts came from outside our group, include contact information for the original source. If the data is proprietary make sure that it is clear that the data or scripts cannot be obtained through our group.

Until there is disk space allocated to this archive each submitter will have to store the tar file in their own directories.

Creating and plotting color bars in Arc/INFO is not a straight forward task. To help make the task easier, several scripts have been developed locally to try and automate the process. The tar file ColorBar.tar.gz contains scripts, a grid file, and a readme detailing the process.

Contact Keith Aric Cherkauer for more information.

The file latlon.c takes an Arc/INFO ascii grid (exported using the gridascii command) and transforms it into a 3-column format (latitude, longitude, value). The file grid_latlong.c reverses the process, taking a three-column (latitude, longitude, value) file and creates an Arc/INFO ascii grid (which can then be imported into Arc/INFO using the asciigrid command). The command line arguments for grid_latlong.c can be used to either let the latitude and longitude range of the data determine the bounds of the final grid, or a bounding box (in degrees) can be defined. Compile the programs and type compiled file name for the usage.

The file lower48.e00.gz contains the state boundaries for the 48 contiguous states of the U.S.

The file tzone.e00.gz contains the global time zone locations.

The file us_streams.txt.gz contains the streams for roughly the area of the 48 contiguous states of the U.S., converted into a format used by GMT, a versatile, free GIS and plotting software package.

The file usgs_invent.txt.gz contains the site numbers and latitude/longitude locations for stream gaging locations of the USGS in the U.S.

NOHRSC has a useful set of data sets at www.nohrsc.noaa.gov/gisdatasets/

The USGS also has compiled a broad list of GIS datasets related to water resources at http://water.usgs.gov/GIS/

This has additional databases supplied for the continental US as part of the GCIP effort at http://water.usgs.gov/GIS/browse/gcip.HTML
