Introduction / Help
The COMAH (Control of Major Accidents and Hazards) Land Information Search is a map based tool that allows you to search for data relating to any sensitive features/area/land located around your COMAH establishment for the purpose of identifying any possible sensitive receptors with respect to your identified credible major accident scenarios and Source-Pathway-Receptor linkages.
The COMAH Land Information Search tool enables you to define your area of interest by drawing a 1km radius circle on a map to represent your area of interest.
The search results will highlight the presence of a range of features such as Scheduled Monuments, Sites of Special Scientific Interest and Native Woodlands that fall within the area you have identified and within a 1km buffer.
Search results are delivered directly from the Scotland's Environment Web partners.
The COMAH Land Information Search has been designed as a search tool and is not intended to be a map browser. However it does enable the user to view individual results against their area of interest.
Draw your area of interest1. Please Note! The button allowing you to draw only becomes available once you have zoomed the map into a scale of 1:64,000 or higher (the scale is found at the bottom right hand side of the map).
2. Draw an area on the map to represent where you are interested in searching. A 1000m buffer will automatically be created around your shape.
3. You can zoom in and out on the map whilst drawing your shape.
4. To delete a whole feature, hold down the ‘Control’ key and click inside the shape.
5. To measure a distance on the map click on the 'Measure' button. A measure dialogue box will appear. Select the measure icon and double click on the map to measure. Double click again to finish measuring.
6. To cancel a measurement and start again, click on the measure icon.
7. When you are happy with the search area you have defined, click the 'Run Search' button.
8. To view the search results on the map, select individual layers.
9. To see the full report click on ‘Show Full Report’. You can print and save it to PDF.
10. Rename and save a search area that you have drawn by selecting ‘Rename and Save Search Area’ within the full report. This feature enables you to reload previous searches should you need to do so.
11. To reload a previous search area, click on the ‘Saved Search Areas’ tab – individual searches are defined by a coloured banding and a date, time and name.
16. You can view each layer's map key by clicking on the ‘Legend’ tab.
