We have invested heavily in developing software tools and mathematical algorithms for geographic modelling, optimisation and visualisation. Our software tools provide a level of control not available through standard GIS (Geographical Information Systems) and incorporate features that are unique to Selective Analytics.
Below we have listed some of our tools, but these just represent the major items. On top of these we have a significant number of mini-tools we can use for data cleaning, optimisation and visualisation.
Spatial Modeller™ is our new web-based modelling and visualisation tool that now allows clients to look at at any modelling results as soon as we have done them. It provides both a presentation mode and an analysis mode which allows detailed exploration of each result.

SAModeller: Large-scale location optimisation
SAModelleris designed to find the best locations for services in cases where there are billions of possible options. SAModeller uses our unique RACL optimiser, developed in conjunction with our academic partners, which is capable of optimising country-wide location problems with multiple criteria in minutes.
SAModeller is designed to hold multiple runs with different criteria so that a range of possibilities can be considered. Each optimisation runs contain a full audit trail with criteria and statistic so that there is no confusion when it comes to choosing the right solution.
SAModeller also incorporates over 40 different visualisers to display different aspects of each optimisation run. This uses the latest Google fusion table technology to display the information as maps, tables or charts.
PublicTran: Public Transport modelling
Any modelling of public services such as healthcare needs to consider ease of access via public transport. The generally available sources of public transport timings are meant for travel planning, not modelling so we have developed our own modelling system which uses the TransXChange database of all public transport, bus, underground, ferries etc. This provides special features such as:
- Generalised coverage during a given time period,
e.g. 9am to 5pm Monday to Friday
- Allows for waiting times for public transport,
e.g. knows likely waiting times for a bus etc
- Uses a ‘multi-transport’ heuristic, e.g. knows if you could catch either bus 64, 192 or 199.
MapPlace: modelling and visual presentation
The MapPlace is designed for healthcare modelling. It allows the user to model different scenario. This is preprocessed (see 2 below) to allow MapPlace to calculate and show different options in real-time.
MapPlace can show the existing situation and a series of possible options optimised against different criteria. Information from each result can be displayed on a map as overlays, pie charts, bar charts etc plus details of each possible option and its fit to the chosen criteria.
In conjunction with InputPlace (see below) MapPlace can model the demand for different services, e.g. Inpatients and OutPatients, different treatments, e.g. maternity, cardiovascular, or different diseases, e.g. diabetes, COPD.
InputPlace: data preprocessor and combiner
InputPlace has been designed to take in multiple, often quite diverse data sources and combine them into a coherent whole. It inspects, cleans, validates and filters data to allow MapPlace to carry out complex calculations and display quickly. InputPlace’s key features are:
- Data cleaning: to ensure accurate data
- Combining: to create an overview from multiple sources
- Tracking: every row of data is traceable to its source
- Anonymise: data passed to MapPlace is anonymous
- Filtering and grouping: allows complex queries on data
InputPlace can hold millions of data items and it carried out various grouping and filtering actions to aggregate data before passing it to MapPlace. This allows MapPlace to carry out quick, ‘what-if’ calculations and displays that would not be possible without this level of preprocessing.
And many more…
This is just a sample of what we do. In addition we have:
- Tools for quick visualisation of data in geographic form. If you have a potential project then consider sending us your raw data and we will produce a map of the current situation.
- Access to a number of standard optimisation and simulation tools, with the experience to know when and how to use them.
- Detailed knowledge of Microsoft SQL server spatial commands and how to use them.
- Detailed knowledge of a number of mapping and GIS tools.
- The ability to provide web-based tools to allow you, after appropriate training, to do the modelling yourselves.
