Digital
image processing support is essential in GIS to handle raster
data sets such as satellite remotely sensed images, and scanned
maps. A custom header is designed in GRAM++ which is appended
to every raster image imported into the raster database.
The software
provides support for:
-
A vector map
can be displayed and the user can examine the associated
attribute data for each point / segment / polygon using
the linkage between the map data and attribute database.
-
SQL base queries
can be generated using a simple graphical user interface
on the attribute database, and vector objects satisfying
the query can be highlighted on the map. This is one
of the simplest and most often used form of interactions
in a GIS.
-
This module also
assists in the generation of statistical maps using
the attribute databases.
-
Queries across
multiple tables/ Queries within a user-specified window.
The data can be accessed from any Open Data Base Connectivity
(ODBC) compliant database.
-
A hierarchy of
maps for eg. from country level to village level can
also be generated using child map facility.
-
Some of the database
operation including addition,deletion and modification
of fields can be done using this module.
