search for: 10km

I would like to create a geographical grid to have a sort of a reference grid for my georeferenced survey data. The grid should be in a xy format, wgs1984 with a 0.025 degree, alternatively 10km, resolution covering -14 to -24 S and 24 to -34 E (Zimbabwe). Additionally I need to be able to export it as a .dbf Hope someone can help an R- novice ! [[alternative HTML version deleted]]

...of sea-depth for 2000 animal locations using 2 million depth soundings. The result was: Cannot allocate vector of size 20351 Kb I've tried to overcome this problem by making the following adaptations. -Increased the max-mem-size to 1.5Gb (Thanks to Thomas Lumley for his help) -Use a max.dist (10km) for the function Krige -Run the Krige computation for each separate animal location while using a repeat loop -Select only those sample locations and data (depth soundings) within a 20km by 20km box around the animal location (So the Krige function does not need to calculate the distance between t...

I am still trying to find some faster clustering technique for search result. One technique which strike to me is, using the Latent Semantic Indexing for Clustering the search result can give better results. In which we don't even need to iterate over different values of 'k'(in K-means algorithm) to cluster documents rather we can cluster whole search result in one go. How Latent

Hi, We are analizing the relationship between the abundance of groupers in line transects and some variables. We are using the quasipoisson distribution. Do we need to include the length of the transects as an offset if they all have the same length?? Also, can we include in the gam models variables that are measured at different spatial scales? We have done an analysis to see what variables

Seeing as IPV4 is near it's end of life (http://www.internetnews.com/infra/article.php/3915471/IPv4+Nearing+Final+Days.htm), I'm curios as who know whether everyone is ready for the changeover to IPV6? Is anyone using it in production already, and what are your experiences with it? -- Kind Regards Rudi Ahlers SoftDux Website: http://www.SoftDux.com Technical Blog:
