“We cannot solve problems by using the same kind of thinking we used when we created them.”

Albert Einstein

Every organization has it’s own maps and database and there is no communication between the city organizations.

There is no clear documentations about the city.

There is no databases that contain the city assets.

There is no city asset management system.

There is lack in the maintenance process.

Big Data and Cities Cities are growing faster than traditional solutions can handle. By the time that a new power plant is onstream, the demand for electricity will have outgrown the extra capacity that it will have brought. By thetime that a road is expanded with an extra lane, traffic will have grown exponentially compared to the‘breathing space’ that measure was meant to offer. Not to mention the extra congestion that building thenew lane will have caused.

• Deliver the important information about the city assets like(Buildings, street furniture and city infrastructure … etc.)

• To be the middle tier between the government and its citizens by giving the citizens the information that they want and take their feedback.

Building information modelling (BIM)

A BIM is a shared knowledge resource for information about a facility forming a reliable basis for decisions during its life-cycle; defined as existing from earliest conception to demolition.

Industry Foundation Classes(IFC )schema

Is the open and neutral data format for openBIM. The IFC specification is developed and maintained by buildingSMART International as its "Data standard". It is registered with ISO as ISO16739.

A geographic information system (GIS)

Is a system designed to capture, store, manipulate, analyze, manage, and present all types of spatial or geographical data.

CityGML

GML(Geography Markup Language): is an XML grammar for expressing geographical features. This allows users and developers to describe generic geographic data sets that contain points, lines and polygons. Using application schemas, users can refer to roads, highways, and bridges instead of points, lines and polygons. If everyone in a community agrees to use the same schemas they can exchange data easily and be sure that a road is still a road when they view it.

the extendible international standard for spatial data exchange issued by the Open Geospatial Consortium (OGC) and the ISO TC211.

• We will deliver our goals using a standardized schemas:

1. IFC: for the full detailed information related to buildings which is exported from Revit software.

2. CityGML: for city information.

3. CityEngine: will import the IFC after mapping and CityGML files into it.

4. Web viewer: to view the information on a map using CityEngine APIs.
