GIS in Cadastral Mapping
A cadastral map is a map that provides detailed information about real property within a specific area.
Cadastral mapping services also enable to user to study additional details, such as survey district names, unique identifying numbers for parcels, certificate of title numbers, positions of existing structures, section or lot numbers and their respective areas, adjoining street names, selected boundary dimensions and references to prior maps.
Cadastral data describes the past, current, and future right, title, and interest in real property, including the spatial information necessary to describe the geographic extent.
The geodatabase, a data storage framework developed by ESRI, can store attribute tables, geographic features, satellite and aerial imagery, surface modelling data, and survey measurements.
Many countries are computerising their cadastral records and creating large, national databases. Land-related data are now being integrated, analysed, and distributed in ways that until recently were not possible.
A cadastre is an information system consisting of two parts, a series of maps or plans showing the size and location of all land parcels, together with text records that describe the attributes of the land
This mapping often portrays block lines, lot lines, lot numbers, road limits, right of way limits, metes and bounds, plan numbers, dimensions and other information about property parcels found on plans of survey. Cadastral data is used for building applications, regulatory permit and planning.
CHALLENGES IN CADASTRAL MAPPING
The challenge many governments face with the collection, management and compilation of cadastral data is:
- The complexity of magnitude: Provincial or state scale issues associated with complexity and volume.
- Data formats: Survey data comes from multiple sources and is in various formats, making it difficult to compile and maintain.
- The state of the original information: Original data may still be in paper hardcopy, which can be difficult to read, poorly maintained and difficult to access.
- Costs: Inefficiencies leading to higher costs to compile and maintain the data.
- Sustainment: Building and maintaining a current database can be challenging due to budgetary constraints.

GIS technology has been too sophisticated, has required specialist users, and has been difficult to integrate into mainstream information technology. This has restricted its widespread adoption by those involved in land administration.
As GIS and associated technologies mature and more data become available in computer form, the use of GIS for integrating land-related data becomes more opportune. Increased openness and integration of data are, however, more than technical issues and are often seen as a threat rather than as an opportunity. The effective implementation of any system of land administration requires the cooperation of a diverse number of government agencies and private sector organizations.
With GIS technology in cadastral mapping, we can even more effectively provide our core target group of business development managers and location scouts with correct and up-to-date information on specific strengths, focuses and developments of our local economy.
And what is even more important: Potential investors can access this relevant information anytime and any.
