Dear Colleagues, a few questions if I may: -I am doing 3 million points, overlays, reprojections and table edits, and an expensive GIS package failed on us 'esrliy' (I like this word, in case it actually is one). So we ran it in QGIS and the entire project saved; hooray! THANKS!!!! Anyways, how about we want to run 6 million points in QGIS ? How to do it best ? Any advise ?
-we find a consistent bug in QGIS when using Mercator projection and with a 180 degree meridian. Chukotka peninsula data do not show up; perhaps you know of a cure ? I am happy to send you the shapefiles and grids to look at. -I love MetaEdit; well, except, I cannot find it in the PlugIns and the website seems to be not supported anymore. http://gis-lab.info/qa/metatools-eng.html Any hints for ISO compliant XML metadata editor with QGIS ? QGIS needs it. Thanks so much again; very best Falk Huettmann On Mon, Aug 26, 2019 at 9:43 AM Falk Huettmann <fhuettm...@alaska.edu> wrote: > Dear Kind Colleagues, > > thanks, I have a similar question, but with an opposite aim: > > We have two points, > and want to connect them, > but then, NOT with the most direct and shortest path. > Rather, with the most meaningful and considerate one. > Like, > length is not to be penalized but other factors, habitats available, > amount of pixels > underneath etc. > Perhaps even showing different scenarios (aka, many paths lead to Rome...) > ? > The path can consist of more than a line, an area connection let's say. > > So in other words: the optimization is NOT done by short distance. > > Would you have any ideas and suggestions on that ? > > Thanks so much for any input > Falk Huettmann > > > > > > > On Mon, Aug 26, 2019 at 2:07 AM Chintan Advani <chintanadv...@gmail.com> > wrote: > >> Hi guys, >> >> I have a shape file with set of points on a road network.
