Typically, you can only access a small area at a time, but you tend to get what you need. And youРІР‚в„ўll need to prepare your budget in advance. YouРІР‚в„ўll need to allow enough lead time for them to process your request. There are many providers willing to capture the data you need, at a cost. Engage a third party to capture it for you on request.

Consider: How efficient is manual capture when producing noise models that span thousands of buildings or hundreds of kilometres?Р”Р€.

Time is inevitably wasted in creating and combining data manually.

However, it can be time consuming and monotonous work that lowers your overall productivity.

Consider: When you need to source the same data in future, will it still be available via open source?Р”В¬apturing your buildings data manually means you get what you need with immense confidence in the data.

Generally, open source data will require some manipulation to suit your needs, often at an additional cost. It can also be difficult to determine if itРІР‚в„ўs up to date and accurate. However, the data may not be complete in terms of geographic coverage and it may lack the data attributes you require. Searching for open source data is a good option if you want to save money РІР‚вЂњ itРІР‚в„ўs free and readily available if the specs align with your needs. There are broadly four options for sourcing buildings data for noise modelling. How can this process be streamlined for acoustic engineers and noise modellers? Sourcing spatial data Plus, estimating the cost of sourcing (or previewing) spatial data prior to needing it, for tendering purposes, is challenging. And who has time to digitise buildings by hand in QGIS? ItРІР‚в„ўs a notoriously manual and time-consuming process.

Inconsistent data formats, gaps in coverage and software integration. Data sources that are fragmented by geographic region and data type. We know that sourcing the right spatial data for modelling and visualisations РІР‚вЂњ at the right time, for the right location РІР‚вЂњ can be, letРІР‚в„ўs be honest, painstaking and arduous for professionals like acoustic modellers and urban planners.

Analysing the context of the proposed development paints a clearer picture of sensitivities around land use.

Understanding how a development may impact local residents, businesses and communities is an essential step in the planning and design process. And the essential acoustic modelling ingredient is reliable, easy to use buildings data. Streamline data sourcing to save time and moneyР”В®nvironmental noise assessments for major developments and construction projects typically require detailed 3D modelling.
