The GIS structural components, which are known as ArcObjects, are structures composed of functions, methods and different properties which are used in software environments in form of encapsulated entities and nowadays have important role in creating GIS softwares.
Despite the important role of these objects in implementation of required concepts and algorithms in GIS softwares, unfortunately the usage of them have been less noticed while the facilities built in GIS software are limited too. On the other hand, the extent of using this technology, in natural resources sciences, agriculture and etc, increases day to day.
In this research, using mentioned objects, a software including 12293 lines of code in form of 275 procedures has been designed and created. The software is capable of managing spatial, non-spatial and time series data (in scale of 1:250000) of gauging station and stream networks. The software provides possibilities to store, edit, query, and display data and also prepares output data.
One of the software individual characteristics, which is not available in other current GIS softwares, is the execution of multiple spatial searches and quary on Geodatabase without any need to load and to display data layers into map display. The other software benefits are the production of figurative data layers resulted from spatial queries that can be displayed and used without any physical origins on hard disk.
