The Marine Geospatial Ecology Tools (MGET) include a geoprocessing script, "Calculate Species Diversity Index for Polygons" that can compute Species Diversity Indices for polygon coverage data. Under the hood, that function uses the R vegan package to compute the measures. cheers, Shaun Thanks a lot Shaun, I downloaded and installed your tool. However, I am not sure if I can use it. My intention is to calculate Shannon entropy index to measure "urban sprawl" (diversity of land use). I don't have points identifying the observed species but polygons capturing different land uses. thanks so much for your answer Miguel

Hi, I am using arcgis 10.0 and I need to install the tool (diversity calculator) that was developed for (ArcGIS 9.2/9.3). I know that At ArcGIS Desktop 10 users have to install ArcObjects SDK for .NET which also automatically installs .NET support. But when I launch the setup for ArcObjects SDK for .NET in the installation DVD. It gives me the error "arcobjects SDK for the microsoft.net framework requires a supported edition of microsof visualt studio 2010 to proceed" Does anyone know what the problem might be?

Thank, I did not explain myself. I do need to create the quadrat grid (240 by 240) first. How can I do that?

Hi I have a shapefile with municipality bounderies with several attributes. I would like to overlay a quadrat grid (240 by 240) on top of the shapefile. Then I would need to attach the attributes of the municipality, to each of the grid intersections that are inside each municipality. thank you very much for your help Miguel

Thank you very much. It works Miguel

Hi all, I have a shapefile with the regions boundary. I need to have a unique polygon that englobes all the regions and then I need to calculate the distance of the centroid of each region to this external boundary. Does anyone knows how could I get this external boundary? I tried union, dissolve, aggregate but I have not been able to obtain it? Once I have this external boundary I will just need to use the MNEAR function I guess. Thanks

Hi all, I need to calculate the number of kilometres in each municipality. I have a layer with the municipalities boundaries and another layer with the road maps. Does anyone know which tool should I use? thanks,

Hi all, I have a raster maop with elevation data for Spain. I also have a shapefile with the municipalitie boundaries. I need to calculta the range in elevation for each municipality. I think that using the overlay/intersect tool I can have a shapefile with elevation data in each municipalitie, but how do I calculate the different between the maximum and the minimum elevation in each municipalitie? thanks for your help

Hi all, I have a raster data of elevation terrain for the 50 provinces of Spain. I did a mosaic in order to get a single raster of elevation data for the whole country. Now I need to superimpose a grid of 90x90 meters that will allow me to calcutale a ruggedness terrain index. Can anybody suggest which might be the best way to acomplish it? thanks
