hi all,

thank you to all those who took time to answer my
query. this was what Mr.Lary Alber suggested me...


if using ArcView 3.2. Key point:  geographic
coordinates MUST be in decimal degrees, not Degrees
Minutes Seconds.

1) Format your data as either a Dbase formatted file
or a comma-delimited ASCII file with the first record
containing the field (column) names.
2) ADD that data file into TABLES.
3) In a VIEW window, select the View Menu and choose
ADD EVENT THEME and follow the prompts. Key is to
identify the x (easting) and y (northing) fields.
4) If you're successful to this point, make that theme
the active theme and select the Theme Menu and choose
CONVERT TO SHAPEFILE. Follow the prompts for shapefile
name and path.


if using ArcInfo 8.1 (ArcTools) since you are using
lat/long

1) Table to Point Coverage: Converts an INFO or a
dBASE table or a text file with X and Y coordinates to
a point coverage.The tool works only with stand-alone
INFO and dBASE tables. Coverage feature class tables
(FATs) and shapefile dBASE tables cannot be
converted.  Table to Point Coverage uses the ArcInfo
commands Generate, Build and Joinitem to generate the
Output coverage.Attribute information present in the
Input X-Y table is transferred to the output coverage.
 The Text file conversion options are used to define
the field properties for the Output coverage's PAT.
Notes The tool requires geographic coordinates to be
in decimal degrees, not Degrees
Minutes Seconds.
2) Coverage to Shapefile.
