Dear List I am trying to find hot spots (i.e. the best places) for particular habitats across a UK county.
I have a Map Plot grid of various habitats (100 ha sq) and another empty grid of 1 km sq. The only information I am interested in is the presence or absence of any particular habitat in the smaller grid squares and finding out how many occur per 1 km square. I am hoping to produce a series of maps of the 1km squares across the county that have the most (and least) of any particular habitat. The map should end up looking a bit like a contour map with a legend to indicate each of the habitat hot spots. I have looked at the help file on thematic maps and it appears that this must be the way forward. I have tried a few options using the help file on thematic maps (and the guide "Inside MapInfo") but have not got anywhere. Any helpful hints and/or instructions would be welcome ... If MapInfo (V6.5) can not do what I hope to achieve could Vertical Mapper (V2.6)? I have only used proper height data with VM so am puzzled as to how I could use it to map presence/absence data. Thanks in advance for any help and I will of course acknowledge any instructions that have helped me achieve my aims! All the best Jacqui Middleton
