WorldWind project shut down, this site probably will be too.

Hello all,

With the recent announcement that the NASA World Wind project has been shut down (https://worldwind.arc.nasa.gov/news/...ension-notice/) there is really very little reason to continue running this forum, and as NASA staff were providing most of the moderation and responses it will likely fill up with spam shortly.

Unless something changes in the near future, I will be shutting down worldwindcentral.com as well as this forum, as it is no longer useful. Most of the data on WWC is referencing the legacy C# version of World Wind anyway.

Thanks,
Matt.

    Having them in the desert makes perfect, if not more than perfect sense.
    The pivot irrigation is a way to make stuff grow where it would be impossible to grow otherwise by keeping it constantly waterfied.
    The middle of the desert is a prime spot for this stuff to be used.
    yes ,of course! quite simply: the question to ask is,Where else but the desert would you irrigate?

      The answer to that question would be any place that has an under adequate supply of surface water. Alot of places in the midwest US use pivot irrigation. In western Kansas and eastern Colorado, you see it alot. I live in Kansas and we do get lots of rain, but in some places, or some years, we just don't get all that we need in order for crops to grow. I also spent a year in Iraq. They have huge irrigation networks on hand dug canals that run from the river to irrigate huge tracts of land. They also use pivot irrigation in many areas that are too far from the river so the dig a well. If you look in the desert enough, you will see alot of holes, they will appear very small, of you can see them at all, on the landsat images as they are just small resevoirs and wells.

        Israel was a desert one century ago. Zoom on it and look the power of water, wich is the blue gold of Moyen Orient. Geopolitic (add-ons in that way should be great) of water in dry places is one of most complicated of the entire world. The rivers are majority not national.
        Or there are many enormous aquifères (I don't get english traduction from french) under the ground of Sahara, billions cube meters of water like under the Mars one. If you hollow, very deep, you get the blue gold.

        And remember that these pharaonics projects are in the historic tail of Nasser (Assouan barrage), who is a kind of model for these actuals "socialist" arab leaders.

        Transform the desert and make it green, like in the terraforming of Mars (read the Mars Trilogy of Keith Robinson, Red Mars and sequels), seems a project of fools, and may be, I don't know. But it's a dream of pioneers, in theses arid places.

            What kind of add-ons are you thinking of - what do you mean by "geo-political"? I'd love to try making them. BTW, the word you're looking for is "aquifers" (or perhaps "wells") in english.
            Note: The above statement is probably an educated guess, derived from much forum reading, IRC chatting, general curiosity, etc. Use at your own risk.
            Before asking, check the FAQ or search, and Ask a good question.

              Aquifers ? Thanks a lot, I was not very far finally

              For geopolitics add-ons, I think about many things. Like progressives historics maps of past lands, countries, empires. The earth didn't change enough since 5000 years (Aral sea drying, or volcanos, or may be 2 meters sea level on certains places due to alluvions, are details when we think in geogologic time, and with our NLT resolution).
              The lands are the same. It would be fine to see human territories maps changing with time.
              But I think further about actual maps showing tensions places (ex : Cachemire zone or Marocco Sahara vs Mauritania, or precisely water territorial complexity in moyen orient), with UN or other links.

              In France, we have a fantastic short TV documentary by Jean-Christophe Victor, the son
              of Paul-Emile Victor, the Pôles and Groendland specialist. We understand everything thousand time faster with his gopolitics maps.
              Where is money, where are the biggers pipe-line of Internet, Oil maps and reserves,


              I don't know the technical way. I'm a quite old timer. I tried to make add-ons but this kind of is a little bit too complicated for me. It's euphemistic :(

              But I guess that they would be great for education.
              May be at start, the historics maps by centuries, or important epochs, seems the more simple way to start... Because the area of this idea is enormous, I repeat

                Aquifers are large reservoirs of water underground, wells are the holes you drill to pump water out of an aquifer.

                    Irrigation in a middle of a desert???
                    In sahara desert?????
                    No chance I say.
                    It maybe looks like a scientific test.

                    My father was in the irrigation business and sold pivots to many countries, including Lybia. Not only are those indeed irrigation pivots, they may be the ones that put me through college! :P

                    Here's an example of them in Saudi Arabia:
                    worldwind://goto/world=Earth&lat=26.80344&lon=49.15316

                    And some in Israel:
                    worldwind://goto/world=Earth&lat=31.23000&lon=34.50961

                    It's an efficient way to grow crops in the desert. The emitters can hang low from the slowly rotating pivot, feeding the crops a nutrient solution with drippers or sprayers, keeping the roots moist and minimizing water waste.

                    Technically, it's a form of hydroponics since the soil does not contain enough nutrients to grow the crops but only serves as a medium to support the plants - the fertilizers have to be continously fed with the water.

                        Why we don't use the Landsat 7 image to find the truth,
                        it is easyly use the image to find out whether it is a crop or water pool.

                              I am really spooked by this! :lol:

                              here is a link for hotspot: http://www.worldwindcentral.com/hotspots/v...spot.php?id=673
                              I would suggest these are open oil resevoirs. It would seem that a scooped out area in the sand would be cheaper to construct than hauling a lot of steel in to erect a bunch of expensive tanks.
