A Fortran program (ADC2ADC.F) to convert an ADCIRC coastal ocean model output file from ASCII text to ArcGIS format. It was developed for, and distributed to, NOAA Coastal Services Center in 2007 and the scientific community to encourage broader usage of ADCIRC datasets in inundation mapping, evacuation planning and other GIS applications.

This program allows a smaller geographical subdomain and time window to be extracted from the full ADCIRC ASCII output file for import and display with ArcGIS software.

• elevation files fort.63
• current velocity files fort.64
• pressure files fort.73
• wind speed files fort.74

• a time window
• a space window
• a flag for dry nodes

Example: Latitude and longitude values can be plotted in ArcMap via the "Add XY Data" under the "Tools" menu.

• header time in hours (e.g., T_49_500)
• time fields to 3 decimal places (e.g., T_49_500)
• latitudes and longitudes up to 6 decimal places

• Grid file (e.g., fort.14 ADCIRC file)
• ADCIRC output file (e.g. fort.63)

1) Download adc2arc.F

2) Compile Fortran code

For Intel compilers you can use:

> setenv FFLAGS "-O3 -FR -cm -w -convert big_endian -mp"
> ifort $FFLAGS -o adc2arc.exe adc2arc.F

Any Fortran compiler should work as long as the code is compiled with an option for extended source length (greater than 72 characters).

3) Run:

> adc2arc.exe

Example input text
Example output text

4) The output file has an ".arc" extension
Example of an arc output file

Note: if modifications to the code are made, please send them to me (my email address is in the code comments) so they can be included in the next version of the code and distributed to the community. Thank you!
