can anyone give file format of the sdf file

[Anonymous]

der sir,
i got surprised by knowing that the sdf require only one file so we get rid of the other file formats like in shapefile as we have .shx,.dbf,.shp,.prj and all.

so is it possible to get file format of the sdf file so one can read it using its own code customize the product as he can

SDF stands for Spatial Database Format. It supports multiple feature classes per file with fully typed properties and multiple geometry properties per feature class. Each geometry property is indexed via an R-Tree. As for spatial operations, the SDF query engine supports Intersects, Contains, Within, Disjoint, and Inside.

The format is built on SQLite, but does not use any of the relational aspects of SQLite, hence you cannot use any of the SQLite client tools for viewing / querying an SDF file. We are just using the low level storage components of SQLite.

thanks a lot sir,

i have get some clue for the sdf file.
but still if i get pdf file of the documentation that describe the total file format of sdf file so one can read it can make its own software.

in the same way we have pdf file of the shp is available with the arc gis documentation, but i am not able to find such documentation for the sdf file.

it is thanful to u if u can provide the documentation or the some web link to download that documentation.

when we are working with the ARC GIS we generate the data fROm that software and develop our own application using the language suc as VB,VC,VC++. and we provide low cost softwre to the client but for that our basic requirement is that we need to know the .SHP file format so that we can load file in our own product.

NOW we have shifted our work to the AUTOCAD MAP2008 we have generated the database using that and get the product in terms of the .SHP,and get the work done by software people,but still we are dependet on the .shp format.

we want to get rid of the .shp format and want to build application on the .SDF FORMAT.

FOR THE ABOVE MENTIONED REASONS WE WOULD LIKE TO KNOW THE FILE FORMAT OF THE .SDF

Maybe not all that you are looking for is available.... certainly not in the PDF format you seem to be after.

goto this site: http://www.nabble.com/Feature-Data-Objects-%28FDO%29-f18162.html

goto this site:http://fdo.osgeo.org/

goto this site:http://www.sl-king.com/
get a copy of fdo2fdo ....

FDO is an open source project so you can even roll-your-own.

and since you have Map3d you have access to all of the FDO apis within .NET

... if you are not near heaven after spending some time at these sites you have missed the point ....

have a great day ...
