FIND Maps now with enhanced map printing

We’ve been asking our users what improvements they’d like to see to FIND Maps. The top response was easier map printing. So we’ve responded, and introduced a couple of significant enhancements to printing.

Printing is important because it enables users to get map and accompanying annotations out of findmaps.co.uk and into a savable and sendable format (PDF or JPEG). The only other way to do this is to ‘export’ the map as data, but this requires high-end professional mapping software to open.

Our software engineers have now added additional map printing functionality to the site to make things faster and easier. The first change makes editing saved prints more straightforward. Now once you've saved a project the print area is clearly marked with a red border on the map screen.

This new feature makes previous print areas immediately apparent; making it easier to identify them and will help users to avoid paying again for duplicate prints. It will also make it easier for users to change text and annotation on the print if needed.

The second new feature adds four standard print defaults scales to all maps. This means you can save time by selecting from frequently used standard map scales when printing. For example, if you are printing ‘Street’ map, it can be printed at 1:10 000 scale by selecting this from the drop down menu.

While making these changes to printing we have also taken the time to reduce the cost of printing the ‘Town’ map (1:50 000). Printing is now £1 for the first Km² and just 6p for each subsequent Km².

We're continually enhancing FIND Maps and adding new data/reports. If you have any ideas about how we might improve the site please send your suggestions to: support@findmaps.co.uk

Scale matters when using digital maps for surveys

Misunderstanding the meaning of scale and its application to surveys can result in products which don't meet anticipated needs. Scale is important because it defines overall content and accuracy of a survey in a very basic way.



Fundamentally scale is not absolutely related to accuracy but in a graphical product it will limit the accuracy that can be achieved.  For example, 1:1 means what it says; a survey which is life size. It does not mean ‘dimensioned in metres rather than drawing millimetres’. For example, 1:100 means that an object 1m long on the ground will be 10mm long on the plan. When talking about relative scale size, a scale of 1:50 is larger than 1:100 and would require a larger hardcopy plan to represent the same physical object or area.

Understanding how scale are used in surveys means producing the required amount of detail to the desired accuracy, without needing to understand all the processes involved. Of course, if you are familiar with specifying surveys then a full specification will get the best for your project, but if that is not your favourite pastime then getting the scale right is a good second best. However, remember for unmapped territory you need a full Chartered Surveyor.

So where do we start? First of all, what accuracy do we need? Traditionally, surveyors will show detail correct to within 0.2mm at the plotted scale. So, if you want detail to be accurate to within 50mm, you should specify a plot scale of 1:250. But don’t forget that this is a guide. It does not apply to underground services and if the accuracy of any feature is critical you should tell the surveyor. Secondly, what detail needs to be shown (resolution)? Normally we show any point objects to scale if they are larger than 1mm at the plotted scale.
