This GIS application tool is used to display and save map layers containing location based data. A map layer has data stored either in different files associated with it like dbf, shp and shx files or can be stored in a database using the SDO_GEOMETRY spatial database object type that can be used to store a wide variety of spatial data like points, lines, polygons etc. The conversions between esri shapefiles and oracle SDO tables are important. ESRI provides a tool for esri to SDO, and the reverse tool is part of this thesis. This GIS application tool can do the following: · Display maps containing location based data from files containing the dataset. · Display maps containing location based data from the database or save them as shapefiles. · Save map layers to the database. · Remove all displayed maps.
