Data Analysis

Building an appropriate and efficient GIS/AM/FM (Geographic Information System/Automated Mapping/Facilities Management) database can be a frustrating and overwhelming task. There are always a number of technical issues to consider from data processing options through to data modeling design discussions. The following outlines some of the more common questions needing to be answered prior to the Data Acquisition and Data Modeling phase of a project.

Data Acquisition

What external data sources exist that are appropriate for the business?
How do we acquire data, such as landbase, to complement existing business data?
What internal data sources exist and what is involved in accessing them?
What processing options exist for acquiring external data or translating existing in-house data or capturing new data and what are the costs involved?
How compatible are the various data sets spatially?

Data Modeling

How do we get the most out of our spatial data?
How can we ensure our data is best meeting our business requirements?
What is UML and spatial database modeling?
What level of accuracy and precision exists in the spatial data and what level is needed for our business?
How can we make the existing data more accessible?

The capabilities and complexity of spatial database technologies is ever increasing and having the necessary skill sets are difficult to maintain, so compromises often occur. This results in databases that are of inferior quality and desirable software features become inaccessible. In the end construction of the spatial database takes longer than necessary and higher costs are incurred.

Orbis Directions has the ability to ensure all the database issues are optimally addressed. Stewart Nimmo has years of experience in understanding the issues associated with managing large spatial datasets and ensuring the database is designed to meet the business requirements. Through both relational and object-relational UML modeling techniques the most appropriate data model will be designed by integrating the right degree of business rules into the data model. The knowledge Stewart Nimmo has acquired and the skills he has developed over time will help you overcome the many technical obstacles you currently face, resulting in the most appropriate database designed to suit your business needs and budget.
