Users may read through the very begining of the C codes provided to get an idea how the data is constructed. This is one of a suite of modules we used to plot the emission data for the state of North Carolina. This group of modules allows displaying points, lines and polygons over a map of the United States. The module suite is stored as a group in a compressed tar file at the International AVS Center, with some sample networks and datasets included. You may find it easier to access the modules this way. The compressed tar file is approximately 1.2MB in size, and can be found via anonymous ftp to avs.ncsc.org, in ftp/avs/Data/avs_dataWang_GIS_mods.tar.Z.</p></td></tr> <tr><td align="left" colspan="3"><table class="avs5_repository"> <tr valign="top"><td><b>Author:</b></td><td>Jeff Wang, MCNC, Environmetal Programs Group</td></tr> <tr><td><b>Version:</b></td><td>1.000</td></tr> <tr><td><b>Language:</b></td><td>C</td></tr> <tr> <td><b>Path:</b></td><td>source/data_input/AMS_extract/</td></tr> </table></td></tr> <tr><td align="left" colspan="3"><p> <a href="AMSextract.shtml" target="_top"> <img src="../../../../../img/readme.gif" border="0" width="30" height="30" alt="AMS_extract"></a> <a href="AMS_extract.shtml" target="_top"> <img src="../../../../../img/readme.gif" border="0" width="30" height="30" alt="AMS_extract"></a> <a href="source/data_input/AMS_extract/AMS_extract.tar.gz"> <img src="../../../../../img/targz.gif" border="0" width="52" height="30" alt="Archive - AMS_extract.tar.gz"></a> <a href="source/data_input/AMS_extract/AMS_extract.tar.Z"> <img src="../../../../../img/tarz.gif" border="0" width="52" height="30" alt="Archive - AMS_extract.tar.Z"></a> <a href="source/data_input/AMS_extract/AMS_extract.zip"> <img src="../../../../../img/zip.gif" border="0" width="52" height="30" alt="Archive - AMS_extract.zip"></a> </p></td> </tr> </table> <br> </td> </tr> <tr> <td>  This module allows users to extract data from AIRS AMS (AIRS Area and Mobile Subsystem) files.
