The User Guide documentation is very brief and the terminology is difficult to comprehend. What is meant by ‘geometries’ and why would I want an atlas of ‘geometries’? Can someone give an example of what it might be used for and how it would be set up? <o:p></o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal style='text-autospace:none'><span style='font-family:"Arial","sans-serif"'>The reason for asking is because I would like to be able to automate the process of creating maps showing wildlife distributions. GIS is used widely in the UK and other countries for storing wildlife data, but until now in order to produce atlases we have used software such as DMAP and MapMate. To those not familiar with wildlife mapping the simplest possible dataset would be a number of records of one or more species, each with an X and Y coordinate. The data can be saved as a shapefile point data layer. Each record is therefore a feature. The data can be styled as ‘single symbol’ so that records with the same coordinates overlie each other when viewed. To see the distribution map for a particular species the data needs to be displayed as ‘rule based’ and a rule set up to filter the records for each individual species (e.g. “Species” = ‘Quercus robur’ filters out records of Pedunculate Oak). The resulting map can then be output to a jpeg in the usual way using Print Composer. This process is unworkable, however, because every time a different species is viewed or output, the filter needs to be manually changed. The only other option at present is to split the data into separate layers, one for each species, so these can be turned on or off as needed. This is workable for small numbers of species but not for 1000+ species as would be required for a flowering plant atlas for example. So is creating a species distribution atlas possible using the atlas generation dialog in version 2, or is ‘atlas’ being used in a completely different sense here? And if it is not possible, is anyone working on a solution? It would be of huge benefit in the nature conservation world if so.<o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'>John Norton, Gosport, UK</span><span style='font-family:"Arial","sans-serif";mso-fareast-language:EN-GB'><o:p></o:p></span></p><p class=MsoNormal><span style='font-family:"Arial","sans-serif"'><o:p> </o:p></span></p></div></body></html>
