Abstract
In this paper, first we are going to discuss briefly the importance of 3D information, and its application because of the Increasing demand for detailed information about real world objects and phenomena including altimetry and planimetry data (X, Y, Z), then we will explain in short the available methods for 3D measurement. It’s important to note that the Information collection by itself cannot define and sufficiently provide all the necessary actions to be taken in order to get them accessible and useful for users. The data management and establishment of a proper and reliable DBMS and finally a GIS system at the same time are vital crucial in the course of 3D application that will be discussed throughout the paper. The existing drawbacks and elements needed to be considered for the cartographic presentation are the key issues in three-dimensional world visualization. The elaboration on the 3D information and its knowledge transfer to the users in a SDI framework as well as the requirement recognition of beneficiary organizations will be the next step in this paper and the most probable problems will be studied in this stage. At the final stage, we’ll come up with conclusion, warnings and recommendation.
Highlights
Increasing demand for detailed information about real world objects and phenomena including altimetry and planimetry data (X, Y, Z), along with attributed information has made tremendous changes in all related Geomatics disciplines and activities

Summary
Increasing demand for detailed information about real world objects and phenomena including altimetry and planimetry data (X, Y, Z), along with attributed information has made tremendous changes in all related Geomatics disciplines and activities. One of the main conceptual characteristics and reasons for a GIS system is to provide possibility to attach and keep information about spatial feature as well as tools for analytical process and creating environment for value-added knowledge regarding the world around us The details of this information can be numeric, semantic along with positional information. The provision of the spatial information is time consuming, cost effective and most labor intensive job which inherits its adjective from Data Collection phase in any types of mapping projects Apart from this phase, the availability of tools that evolve around the real or virtual world data, is advancing throughout software development and existence of appropriate application-oriented software. The Geomatics community has a very difficult situation to comprehensively response to the current expectations raised in a daily base management requirement tools
