digital form, at least 1600 X 1200 resolution, full color, and saved in the

names will be descriptive (i.e. WMS XS_20343_US.JPG, not
IMG014.JPG). Photos of the channel or cross -sections shall be labeled
as to direction of flow.
Scanned Documents: Scanned documents will be provided in Adobe
PDF format, with the entire document appearing in a single file (not
individual PDFs for individual pages or for chapters). Bookmarks to
chapter beginnings and other important pages will be provided in the PDF.
G/S Spafia► Dafa File Formats:
All GIS vector data layers (points, lines, polygons, etc.) shall be provided
in one of the following three ArcGIS compatible formats: personal or
file geodatabase (preferred), shapefile, or coverage. Continuous surface
model data (i.e. DEMs or DTMs) shall be in ESRI's GRID or TIN format.
The City will provide the elevation data for each study area plus a 500 foot
buffer in the LIDAR LAS binary file format. Aerial photography or other
raster imagery will be provided in a common GIS image format (preferably
GeoTIFF), with appropriate header information and a world file for
georeferencing. If large amounts of raster images are required for the
project, and image catalog will be created and provided to the city.
All GIS data, and other files containing coordinates, shall use the State
Plane coordinate system set to the Texas North Central (4202) zone. The
horizontal datum shall be the North American Datum of 1983 (NAD83) and
the vertical datum shall be the North American Vertical Datum of 1988
(NAVD88), both the horizontal and vertical units shall be in feet. All
surveyed data shall be captured or converted to grid coordinates. If
conversion is required, the surface to grid conversion factor shall also be
provided. All GIS datasets shall have the projection defined either
internally (geodatabases) or with a projection file (shapefiles).
A FGDC compliant metadata file shall be provided for each GIS dataset.
This metadata will be compatible with ArcCatalog and saved in XML
format.
Data accuracy shall be reported and checked using NSSDA standards
instead of other older standards like WAS or ASPRS.
Atl submitted data files must not contain any server link references to the
server network and file folders.
