GIS Data & Metadata

This Open-File Report contains ready-to-use GIS data that was prepared using ESRI's ArcView, ArcGIS and ArcInfo. Data pertaining to this report can be view directly off this CD-ROM by opening the ArcView project "FGB_OFR.apr" located in the directory "Data." (note: If you do not have ArcView, you will need the FREE GIS browser ArcExplorer which may be downloaded from ESRI at www.esri.com). Otherwise, the individual datasets are available for download, to be used with you own GIS mapping software.

ArcView Project:

Project Info and Instructions

The directory "Data" of this CD-ROM contains an ArcView project file called FGB_OFR.apr which was created on a Windows2000 system using ArcView 3.2a. When using the CD, either double-click on the filename to launch ArcView, or open ArcView and load the project (see README for software requirements). The project file has been modified to reflect relative pathnames to files, so it should work from the CD-ROM drive, regardless of the assigned drive letter. However, this project files contains grids and requires the user have the Spatial Analyst extension to open the project. For those users who have ArcView, but not Spatial Analyst, open the ArcView project file in the data directory of the CD-ROM entitled FGB_nosa.apr. This ArcView project does not contain any of the gridded surfaces. Those grids can be loaded as images, but because the grids are floating point grids the default colormap loaded is grayscale which does not reveal many of the details of the surfaces.

Hotlink button from ArcView 3.xHotlinks: These ArcView projects contain hotlinks which, when run off the CD-ROM, will link sediment sample locations to a pop-up photo of the sediment grab sample. These hotlinks will work in both the Spatial Analyst and Non-Spatial Analyst versions of the project but will only work when running the project off the CD-ROM. Hotlinking is activated by making the sediment point shapefile the active theme, selecting the hotlink button (left) from the view toolbar and clicking on a sample in view "2. Bottom Sample Locations & Photos."

For the hotlinks to work with these ArcView projects, the user must supply information regarding the data location. When the ArcView project is first opened, a window will prompt the user to enter the location ArcView project file (the root directory, i.e. "d:/data/"). If the file is read from the CD-ROM, then the drive letter of the CD-ROM is what needs to be filled in. If the whole contents of the CD-ROM are copied to the hard disk, then this directory information needs to be entered at the prompt. This procedure only works of the directory structure of the CD-ROM is kept in tact when moved to the hard disk.

Download GIS Data:

The tables below represent the GIS data available for download pertaining to USGS Open-File Report 03-002. The first column contains a description of the dataset as well as a link to the metadata file and a browse graphic of the data. The second column contains a .zip file for each data file. To use these data with your own GIS mapping software you will need to unzip each of these files to a local data directory using an unzipping program such as WinZip (a trial version can be downloaded from WinZip at http://www.winzip.com/download.htm). Once unzipped, shapefiles should be ready to use with ESRI GIS mapping programs. Note that grids from this Open-File Report are made available here as zipped ascii files and must be unzipped and then converted to grids using ArcToolbox, ArcInfo, ArcView or other GIS software. ArcGIS layer (.lyr) files are included within most of the zipped data files (.zip). Because layer files simply link a legend to a data source, you may need to update the links ("set data source") within the layer file and set it to where you have placed the data on your own system. In addition, the zipped data files ferltxtr.shp, caco3.shp, ef_interp.shp and wf_interp.shp also include ArcView legend files (.avl) which were created using ArcView 3.2a.
