eSpatial mapping software provides the United Kingdom (UK) constituent country, English government office region, English and Welsh county and unitary authority, local authority, ward, UK postcode area, UK postcode district, UK postcode sector and UK postcode unit boundary datasets. The English and Welsh boundary datasets provided by eSpatial where obtained from the Office of National Statistics 2011 English and Welsh census. The 2012 UK postcode boundary datasets which eSpatial provide where obtained from Map Logic LTD. These boundary datasets can be used in conjunction with your own personal or commercial data. The eSpatial mapping software facilitates the linking of your own data with these boundary datasets allowing for a visual analysis of your data on a map. These boundary datasets can also be used in conjunction with your own data to create reports in which your data is summarized in relation to these boundaries. Below is an example of this kind of report. This report was designed by eSpatial to illustrate how to get the most out of the eSpatial mapping software and the data it provides.
A heat map report was created using the eSpatial mapping software, the English and Welsh county and unitary authority boundary dataset and a sample sales dataset which was created for the purpose of this report. This report examines total sales in relation to these county and unitary authorities. This report could also have been ran against any of the other UK boundary datasets which eSpatial supplies but for the purpose of this sample report the English and Welsh county and unitary authority boundaries were chosen.
County and unitary authorities are colored and categorized according to the total number of sales within them in 2012. The graduated color scheme adopted by eSpatial mapping software allows for a quick and easy analysis of this data. It is evident from the map that yellow colored county/unitary authorities (e.g. Worcestershire) have the lowest sales totals, less than 270,000 while red colored county/unitary authorities (e.g. Oxfordshire) have the highest sales totals more than 730,000. It is also therefore easy to surmise that the sales in the light orange (e.g. Surrey), orange (e.g. Wiltshire) and dark orange (e.g. Hampshire) colored county/unitary authorities lie somewhere between 270,000 and 730,000 respectively.
Firstly the topic reflected in the map can be changed quickly and easily simply by selecting the map this field option. Once this option has been selected the map will change to reflect the values in this topic (e.g. select the map this field option on Sum (Total Sales 2011) to see the 2011 values mapped in relation to the English and Welsh county and unitary authorities). Secondly the report can be sorted in ascending or descending order. This is useful when trying to decipher quickly which areas have the highest/lowest values (e.g. select sort ascending on Sum (Total Sales 2012) to see which county/unitary authority has the lowest number of sales). Finally the report can also be filtered by specific values. This is useful when trying to quickly search for areas with specific values (e.g. select filter results on (Total Sales 2012) so that states with between 100,000 and 300,000 sales are only displayed on the map).
