GIS provides tools and methods for the integration of different data into a format to be compared and analyzed. Analysis models comprise simple user-defined views to complex stochastic models, like suitability analysis, network analysis, optimization, allocation, etc. Geometric modeling has immense ...
In Geographic Information (GI) technology, it is essential to find suitable mappings between the — one and only — 'real world' and — several possible — 'virtual worlds' that constitute greatly simplified copies of the original, omitting aspects that are irrelevant for a certain range of ...

Pre-processing Data in GIS When working on a GIS project, the first issue or decision that cartographers have to face is how to incorporate data into the system. This is the process called “data capture”. The fact that data capture is one of the most time consuming processes in GIS, ...
ArcGIS Enterprise, a foundational system for GIS, runs behind the firewall, on premises, or in the cloud and powers comprehensive functionality via apps and add-on capabilities.

Process modeling is another approach to designing GISs. Instead of identifying data first, process modeling seeks to identify processes, transformations...
ArcGIS Proreads building information modeling(BIM) filesas an ArcGIS workspace of feature classes called a BIM file workspace. The BIM file workspace is organized into feature datasets named after conventional construction disciplines. These disciplines include architectural, structural, electrical, mechanical...
Spatial hydrology modeling such as extracting watersheds and flow lines also uses a raster-based system. Spectral data presents aerial or satellite imagery which is then often used to derive vegetation or geologic information by classifying the spectral signatures of each type of feature. Raster dat...
In linear infrastructure project, we have to integrate geospatial information. In geospatial information modeling and in Geospatial Information System (GIS), the level of detail concept is generally dedicated to model objects with the most relevant geometry and representation according to a specific ...
