from open view to sensors to a geospatial reference - thanks for your patience
I read Dutton's paper a few years ago and noticed it relied on a non-recursive approach. The use of "N" and "S" in the major triad designations, inconsitent numerical coventions (Dutton's scheme can be described as binary/octahedral) but the most glaring difference between his HTM and this recursive triangular mesh is the methodical and consistent method for designating minor triads. but from the comments I've read here so far, my explanation is found wanting - it seems nothing short of an conversion application will do. thanks for the input. - bg > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] Behalf Of michael gould > Sent: Wednesday, June 13, 2007 2:11 PM > To: [email protected] > Subject: [Geowanking] RE: sensor obs > > > Brian (Grant): your HTM sounds an awful lot like what ou find googling > "dutton qtm" > > Hope that helps. > > Cheers, > M Gould > > ------- > Michael Gould > Centro de Visualización Interactiva www.cevi.uji.es > Dept.
