1.From http://data.labins.org/2003/ > Quad Index (pdf file)> find 2 adjacent quads
in Escambia
County, Florida. Selected 5160
Perdido Bay and 5159 Fort Barrancas.
2.From Labins select DOQQ using 2004
RGB StatePlane, FT MrSID for both quads.
Extract all files for both
quads (NE,NW,SE,SW of types
3.USX, SDW,SID). Saved to folder
called s:Intro to GIS\Week 6\Projections Assignment
Information about the Data: Projection: State
Plane
Datum: NAD83
Units: Feet
Graphics Type: MrSID
World File: sdw
Resolution: 1-meter
Color: True Color (not CIR)
4. Check ArcCatalog to make sure file has the
correct spatial reference.
State Plane: NAD 1983 StatePlane Florida North
FIPS 0903
5.Update projection of other files cntbnd.shp, qd24, and majrds_feb10
From the toolbox, Double-click Project tool Project

6.Open all files in ArcMap.
7. Open Excel and import
fileEscambia_tanks.xls.
Add columns for Xcoor and
Ycoor. Use formulas for converting lat/long to decimal degrees (DD):
X = LATITUDE with FORMULA of DD=degrees +
(minutes/60) + (seconds/3600)
Y=LONGITUDE with FORMULA of DD =((degrees +
(minutes/60) + (seconds/3600)) *(-1)
The negative for Y is because the US is West of
the Prime meridian so all longitude is negative.
Hover curser on bottom right of Xcoor column
until a plus sign pops up.
Click and drag to the bottom of the file data. Do
the same for Ycoor.
8. Add Data to a Blank ArcMap
page. File ; Add Data>XY Data.
