GLINT & GLARE ANALYSIS and ASSESSMENT
An area of increasing activity in the Irish renewable industry over the past number of months has been that of solar photovoltaic (PV). Along with the usual planning requirements of LVIA, photomontage, ecology etc. comes another requirement quite unique to Solar PV developments: the phenomenon of glint & glare. Although Solar PV arrays are designed to absorb as much light as possible, there are certain times of day where some sunlight may reflect off solar panels causing a potential for nuisance to certain receptors.
Innovision has been working hard to develop a robust methodology to address this issue. We are pleased to announce that, with the benefit of training from the United States, we can now assess potential glint and glare effects from proposed solar developments on residences, flight paths and transport routes.
The visual and analytic nature of glint and glare assessments can be comprehensively addressed using Innovision's core services of GIS and mapping. This allows us to produce a robust and visually appealing document which can be easily understood by members of the public and local authorities alike.
A Geographic Information System (GIS) is a means of capturing, manipulating and storing spatial or geographical data. This data can then be analysed, managed and presented in a clear and understandable fashion. Innovision has all the necessary skills, experience and equipment to engage in detailed GIS analysis, regardless of the scale of project. This allows us to transform complex datasets into a visual resource which can be used to help make informed decisions.
We can capture data to a mapping grade standard using the very latest in GPS mapping equipment and can even create bespoke systems to help efficiently capture data for a specific client need.
We can also carry out desk based data collection such as digitising from ortho-photography, geo-referencing scanned or historic maps and asset management.
SPATIAL & 3D ANALYSIS
Spatial and 3D analysis is a crucial part to any GIS work. It enables interesting results to emerge that are not necessarily apparent in the initial raw data. The resulting visualisations greatly assist decision-makers in understanding complex situations. For example, where does your customer base reside and what areas should you target? Or, perhaps you have a proposed structure in an environmentally sensitive location and want to explore the possibilities of reducing visual impact.
These are just some of the scenarios in which spatial and 3D analysis can be utilised to help your company achieve its objectives.
ZTV or Zone of Theoretical Visibility analysis is the process of producing a map indicating areas which, in theory have a view of a proposed development such as a wind farm, solar farm, chimney stack, telecommunications mast or building. From this map the reader can quickly rule out places within the study area which simply have no view of the proposed structure. No further assessment needs to be carried out in these areas from a visual impact point of view. These maps are a requirement for a lot of larger planning applications and are also very useful in the selection of viewpoints for photomontage.
The ZTV process can also be reversed which allows the client to see where a development can potentially be built without it impacting (visually) on a particular sensitive receptor. This is particularly useful for proposed developments near a highly sensitive amenity, village or archaeological site.
Innovision can provide a map indicating optimum areas for project development which take account of height restrictions relating to the receptor.
