ArcGIS Project Read-Me

The map documents and shapefiles used to create the trackline maps provided on this disc can be found in the arc.zip file located in the ARC subfolder of the SOFTWARE folder located at the top level of the disc. 
The map documents were created with Environmental Systems Research Institute (ESRI) ArcGIS 9.1 software.  Shapefiles may also be viewed with other versions of ArcView, ArcGIS, or public domain software ArcExplorer
(http://www.esri.com/software/arcexplorer/index.html).
The Points to Lines ArcScript, downloadable at 
http://arcscripts.esri.com/details.aspdbid=12702, was used to create the swath / side scan and singlebeam trackline layers.

The list below describes the shapefiles provided with the ArcGIS project.  The project, Sarasota_Bathy_SS, is divided into three group layers, one for each of the data types collected during the survey.  Metadata are available as HTML documents (viewable with any Web browser) and XML documents (used by ArcCatalog).

The Side Scan Sonar Mosaic layer contains:

Swath_and_Sidescan_lines:
line layer of 06FSH01 side scan trackline navigation

Sarasota_SS_final.tif:
Georeferenced tiff image of side scan sonar mosaic


The Submetrix_Swath layer contains:

Swath_and_Sidescan_lines:
line layer of 06FSH01 swath trackline navigation

SARAS_SW Events:
table of 5-m gridded x,y,z values for the processed swath data

Swath_5m_shp:
point layer shapefile created from the above table

Ordinary Kriging:
interpolated surface of swath bathymetry created by kriging method 

Swath_raster_cell32:
raster layer for interpolated swath surface created using the export to raster command

Contours_swath:
polygon layer of 1-m bathymetry contours for the interpolated swath surface


The Singlebeam layer contains:

Singlebeam_tracklines:
line layer of 06FSH01 singlebeam trackline navigation

grd_5m:
raster layer of interpolated singlebeam bathymetry surface based on nearest neighbor method and gridded to 5-m

grd_10m: 
raster layer of interpolated singlebeam bathymetry surface based on nearest neighbor method and gridded to 10-m

grd10_hill:
raster layer of hillshade values created from the 10-m gridded singlebeam bathymetry

ctour_1from10mgrd:
line layer of 1-m contours created from the 10-m singlebeam bathymetry grid
