ArcView® Project Files (for V. 3.x Users Only) ArcView® Project Files (for V. 3.x Users Only) For those users with ArcView geographic information system (GIS) software installed on their computers, two ArcView V. 3.x project files have been included on this CD-ROM. These project files incorporate all of the vector and image data that are available on this CD-ROM set. The file named landcov.apr contains all of the Coastal Change Analysis Program (C-CAP) images and ancillary data sets such as streets, census information, and hydrology. The LIDAR project file, lidar.apr, contains the LIDAR BeachMapper data, including contours and ancillary data. Project files have been created for users who have ArcView Spatial Analyst as well as users who do not have Spatial Analyst®. The LIDAR project file was developed to determine whether or not the user has Spatial Analyst installed on their computer. The Spatial Analyst extension allows spatial modeling and analysis to be performed in ArcView. This extension must be purchased separately from ESRI.
The ArcView project files are located in the root directory on the CD-ROM. To use either of the project files, start ArcView, then under the File pull-down menu, choose Open Project, navigate to the CD-ROM drive, and select landcov.apr or lidar.apr.
This option is available to users with ArcView software on Windows® or UNIX platforms. To learn more about ArcView, visit the Environmental Systems Research Institute (ESRI®) home page.

Adobe Acrobat® Portable Document Format Map Images |
Adobe Acrobat Reader is free software that allows you to view, navigate, and print Portable Document Format (PDF) files across all major computing platforms. Whether or not users are proficient with ArcView or other GIS, they will be able to view the 1990 and 1995 land cover data, change analysis data, and LIDAR data from PDF map images contained on this CD-ROM. Furthermore, unlike some software packages that are limited to selected platforms, Adobe Acrobat Reader is available for a wide range of platforms including: Windows 95, Windows NT, Windows 3.1, Macintosh, LINUX, IBM AIX, Sun SPARC SunOS, Sun SPARC Solaris, SGI IRIX, HP-UX, Digital UNIX, and OS/2 Warp. To learn more about Adobe Acrobat Reader, visit the Adobe home page.
Why use the PDF for map display? Documents or images created with any software package can be converted to a PDF file. With the free version of Adobe Acrobat Reader provided on this CD-ROM, any user can view PDF files regardless of whether the software originally used to create the files is installed on their computer. Because of the intense density of the data, the PDF files will not draw properly from your browser. To view the PDF files navigate to the pdf directory on this volume of the South Carolina CD-ROM set. Select islands to view LIDAR maps or counties to view land cover maps.
This free PDF viewing software is ready to be installed from this CD-ROM. For instructions on installing Adobe Acrobat Reader software and accessing the PDFs contained on this CD-ROM, click here.
ArcExplorer®
Project Files (Windows 95 OR NT 4.0 Users Only)ArcExplorer is a lightweight GIS data explorer developed by ESRI. As a stand-alone application, ArcExplorer allows users to display and query a wide variety of standard data sources. ArcExplorer also features legends, overview maps, multiple views, saving and retrieving views, and map printing. With ArcExplorer you can:
- Use a wide variety of vector data formats.
- Display a wide variety of image formats.
- Pan and zoom through multiple map layers.
- Display data using classifications, symbols, and labeling.
- Identify and query geographic and attribute data, and much more.
This free GIS software is on this CD-ROM and ready to be installed. For instructions on installing the ArcExplorer software, accessing the ArcExplorer project files, and a description of the ArcExplorer project files contained on this CD-ROM, click here. If you've never worked with GIS software, give it a try — it's easier than you think!

LIDAR Loader Extension (ArcView V. 3.x Users Only)The LIDAR Loader is an easy-to-use ArcView® extension included on this CD-ROM. It was designed to allow text files to be displayed as a theme in ArcView. The LIDAR Loader automatically opens the text file as a table and then adds the table as an event theme.
To use the extension, open ArcView, select the LIDAR Loader extension, and then click the Bex the Dog
icon. The final result displays the x,y points as elevation points in 16 shades of green in an ArcView View.

LIDAR Data Handler Extension (ArcView V. 3.x and Spatial Analyst Users Only)The LIDAR Data Handler provides users with tools to manipulate LIDAR data. This extension requires the user to have Spatial Analyst, because the tools in the Handler were developed to work with the Arc/Info Grid format. You can use data that you downloaded from LDART and interpolated to a surface, or you can download some sample data files below that have been interpolated already. These files are in the binary raster file format, which is described in the metadata for each file.
The LIDAR Data Handler contains eight simple tools designed to help you manipulate grids. Although it was designed with digital elevation models (DEMs) and LIDAR data in mind, many of the tools could be used with other kinds of grid data.
There are three buttons for working with the legend:
- Legend Scaler - Allows you to interactively scale a legend (AVL file) to your range of data, or any range that you want.
- Legend Loader - Allows you to apply a legend (AVL file) to any number of selected grids at once.
- ColorMap Editor - Allows you to edit the red, green and blue (RGB) values of any of the classes in the grid legend.
There are three buttons that allow you to manipulate and extract grid data:
- Grid Subtractor - Allows you to subtract one grid from another.
- Cut/Fill Calculator - Allows you to calculate volume and area gained and lost from a difference grid (such as one calculated by Grid Subtractor).
- Grid Clipper - Clips a grid by a selected polygon theme or graphic. This can be useful if you want to calculate differences for a small section of your grid.
- Grid Profiler - Allows you to create profiles or transects across selected grid themes.
- Graphic To Shape - Allows you convert a selected graphic (perhaps one that you have used to clip a grid) to a polygon theme.
This tool is available on the CD-ROM at: /exten/lidhandl.avx.
BeachMapper (Windows 95 OR NT 4.0 Users Only)This is a Java software tool was designed to allow the user to view beach profiles and elevation maps extracted from raw LIDAR data. The easy-to-use interface permits the user to choose the South Carolina Office of Ocean and Coastal Resource Management (OCRM) survey monuments or insert known x,y coordinates for a specific area. Both profiles and the elevation maps can be viewed on the screen, printed, or saved as a text file. To view the elevation text file in ArcView, the user can either follow the steps in the Using LIDAR Data in an ArcView Project or use the LIDAR Loader extension.
The BeachMapper application and HTML instructions for its use are located on the second volume of South Carolina's Coast: A Remote Sensing Perspective CD-ROM.

Metadata Collector (ArcView 3.x Users Only)The Metadata Collector v 2.0 is an easy-to-use software application that can be utilized by any ArcView 3.x user without having to fully understand the Federal Geographic Data Committee's (FGDC) "Content Standards for Digital Geospatial Metadata." The tool provides a dialog for creating FGDC compliant metadata for most data types supported by ArcView. The tool automatically extracts information (metadata) such as bounding coordinates, spatial data organization information and attribute information. In addition, the tool allows users to store information as .dbf and text (.txt) files that can be edited, if needed, and reused for subsequent metadata records. The application generates output in both text and HTML formats. If you are creating metadata for an ARC/INFO® coverage, you also have the option of generating an INFO file that will become part of that coverage.To learn more about the tool and how to use it, click here.
