How do I go about creating a map of the earth in QGIS or Openstreetmap, etc. and then export art in the appropriate projection so that it can be wrapped around a sphere?

Working with QGis and data from Natural Earth I would like to prepare a world map (1:50 000) for a globe that can be printed in 6 segments, which glued together build a ‘sphere’ (ball) according to the following graticule:    What projection would you recommend (Winkel tripel?) and how can I export the result (probably segment by segment?) via the print composer to a vector graphic program that allows me to generate the final printing layout (CMYK)?    I am not (yet) an experienced GIS user; the result will be used as teaching aid in poor South American schools.

Is it hard to do a script where I can create a lot of spheres? I have a csv file with x,y,z,r (radius) coordinates. I saw some topics but nothing worked to me.

The question itself is really simple: How can I make the sphere draw a line?    The only idea I had was to use a particle system to create a trail of particles behind the sphere. This didn't work since I wasn't able to make the particles stay in place. I didn't find anything by using google so I hope someone can help me here.

In Cycles, is there a way to create a procedural texture that follows the longitudinal lines of a sphere? Like a beach ball or globe? The texture should be able to be mapped to any sphere-shaped object, not just perfect spheres.    My current approach is to use a rotated wave texture, but that doesn't come from the poles (It uses latitudes)

I am attempting to create a 24x36 map of New York City, and overlay it with a shapefile from City Planning. I'm using the Openlayers plugin, and I've tried all of the different types of base street map layers. I have been able to successfully convert the shapefile from a NAD 83 projection (EPSG 2263) to a WGS 84 projection (EPSG 3857), but I'm still suffering from some type of shift whenever I draw the map out on the print composer on a large scale piece of paper. The larger I try to print, the more dramatic the shift the misalignment.

After reading  It seems that there is no perfect solution for getting rid of the stretch at the poles of UV spheres.  According to , icospheres can be used for stretch-less UV mapping:     All faces have the same area, which may be useful for certain types of UV mapping containing non-organic textures. An example that comes to mind is an isocahedral die or billiard balls where stretch must be minimized near the point where the number is printed onto the ball.   Incidentally, a lowish-poly billiard ball is exactly what I'm attempting to create.  However, my attempts at neatly unwrapping an icosphere have mostly failed (smart UV unwrap works perfectly for using baked textures, however I was hoping for something more like the example in the 6th post of , with a nice clean rectangular map).  How can an icosphere (I assumed the term "geosphere" in the thread was referring to a (geodesic) sphere made of triangles, like an icosphere) be cleanly unwrapped? Or if it's not possible, is there another way to do this which I'm missing?    I'm planning on using the resulting sphere in the BGE.

I'm looking for a qml file (or equivalent e.g. sld) to allow me to use QGIS to take OpenStreetMap data and produce paper maps. I'm re-asking this question (it was asked once or twice over a couple of years by other people) because I'm really surprised not to easily find such a thing already (I looked hard).   I have found  - which are good, but only style basic data like roads (and do so simply). I've successfully followed the  for getting OSM data to work with. I've carried out some basic style editing successfully. I realise I could create my own styles for this purpose - but this seems like a very big job. I want a visually pleasing map taking into account most of the data available on OSM (i.e. not just streets, but tracks, paths, rivers, woods, lakes, buildings and so on). I'd have thought that there would be other people out there already doing the same... It seems odd to have to re-invent the wheel when both OSM and QGIS are open source / open data projects. I feel like maybe I've just missed the obvious repository of OSM qml files which resides out there on the internet somewhere if you know where to look.  Additional notes in response to query below...  Ideally I'm looking for a Mapnik style rendering of the OSM data, but any equivalent properly developed and complete style would be good.  At the moment the objective is to use this data to produce paper mapping, but simple use of the mapping as base data on which other geographic data can be displayed also requires a decent rendering. At work I use Ordnance Survey data completely styled to produce a full and very detailed UK map (the point being that I didn't have to design this styling, it came with the data). I realise that other tools exist for paper mapping, but the same issues tend to arise at one stage or another... I'm more or less successful in making the tool work for me in really basic terms, but to get to something visually useful I end up back with me either needing to re-invent a complete rendering style from scratch (beyond my skill), or encountering such a complex set of requirements for database setups or whatever that the process crashes and burns before I get anywhere useful. With a few more years of GIS experience I'll maybe be a database, CartoCSS (or whatever else) wizz... but until then I'm prevented from using the amazing resource that OSM provides by this one barrier.  Update (July 2015): Please note that I'm still looking for information on this, and given that I've just been informed that the question has had 2500 views in the last year clearly others are too.

Suppose I have a set of coordinates in latitude and longitude.  What would be the easiest way to export those to an SVG file?  I'd rather do this programatically (any language or library will do) rather than manually, but can revert to that if necessary.

I am making a sphere with the radius of earth (6371000 meters). I have only limited zoom out and that makes it impossible to add something on the terrain. If I press F, it does not zoom out further than I could before. I tried to add a very large object like terrain and hitting F, but the zoom was still not sufficient.   I am using Unity 5.2.1

I have an image with known boundary and projection EPSG:4326 and want to overlay it to openstreetmap using Leaflet.js.   I have tried using function imageoverlay, but the image is not aligned with the basemap.   L.imageOverlay(imgUrl, [[-15, 75], [45, 145]], {opacity: 0.6, autoZIndex: true});   So, I use gdalwarp to transform the image projection to EPSG:3857.  gdal_translate -of Gtiff -a_ullr -15 145 45 75 -a_srs EPSG:4326 test.png out_4326.tiff gdalwarp -s_srs EPSG:4326 -t_srs EPSG:3857 -ts 850 728 out_4326.tiff out_3857.tiff gdal_translate -of png out_3857.tiff final.png   However, the final image looks like distorted. Here is the original image.    Here is the final image

I'm using the Autopano Giga 4.4 and Autopano Video Pro 2.6 to stitch and create spherical content, but I've recently moved into wanting to create 360° tours via Unity. I know this is partly a developers question, but if anyone out there can help me with the right specs for exporting a spherical image or video from Giga to use to create the image for the inside of the sphere on Unity, I'd appreciate it!  Experimenting with Premiere and FCPX to edit highlight reels of spherical content, I've had seamless experiences created. For some reason in Unity, the images appear to be stretched around the sphere wrong and it's creates issues on the top and bottom of the image:    The image shown is the bottom of the sphere. I'm using the Android platform to hopefully turn these tours into apps when completed. Thank you for any help!

What I would like to do is to project world map from EPSG:4326 to other ones in geoserver ,special for the Esri EPSG world projection methods. GeoServer has so many EPSG codes in the demo/srslist, but seems most of them do not work. For example,from EPSG 4326 to 54052 PROJCRS[&quot;World_Goode_Homolosine_Land&quot;], I put the gt-epsg-extension-23.2.jar which mainly support the Esri EPSGs to the GeoServer lib path，it should have done for it's projecion, but nothing happens. So how to make GeoServer support the Esri world map projection, like &quot;World_Goode_Homolosine_Land&quot; 54052, &quot;World_Bonne&quot; 54024 or &quot;World_Winkel&quot; 54019? GeoTools maybe supported the Esri EPSGs, does some errors happen in the GeoServer inside?

All of the most powerful texturing applications require a color ID map (Substance Designer, Substance Painter, Quixel DDO). I've been using a Maya plugin called Nightshade Blockout to export color maps for use in these programs. Nightshade may be one of the most-used plugins for texture artists abroad, simply because it's referred and linked by those giants.      I would hope it's as simple as assigning a material color and baking the texture, but it's safe to assume such a map wouldn't come with edge padding (extending the boundaries of each color island by a certain number of pixels, to hide seams during the texturing process).   If there is a Blender workflow/plugin for this, I would love to know about it!  Thanks for reading,  Allen

Ok so I got as far as getting the colors I want, and making them gradient. Now my question is how do I get the colors to wrap around a circle mesh like the rings around a planet? Im guessing it has something to do with mapping?

I'm looking for a shapefile containing an 1000m or 2000m UTM grid ("graticule"). All I was about to find on the web is a 10000m UTM grid (here: ) and I am aware that a 1000m UTM grid for the whole world might be quite big.  That's why I'm now wondering if and how it would be possible to generate such a shapefile for a part of the world. I would prefer to use open source tools like gdal. Others output formats than a shapefile might be ok too.   Has anyone an idea?

QGIS Pisa 2.10.1 Mac Pro, Mac OS   I don't seem to be able to create a simple World Map using the Natural Earth Dataset and the Robinson World projection, unless I zoom in. What could be the problem?

I have slight experience with ArcGIS, but am new to QGIS.  I'm trying to set the projection of my map, and I understand that this is done by altering the CRS (coordinate reference system) of each layer and/or the entire project.  When I right click a layer and select "Change Layer CRS", however, the visual representation of the map (the distortion) does not reflect the selected projection. My world map looks like it has a Robinson (or similar) projection, even if I select a Mercator CRS. The EPSG code in the lower right corner changes, as do the coordinates.    Setting the project CRS to the same projection does not help, nor does enabling on-the-fly projection.  My goal is to export the map to SVG, so the visual distortions are important.  Am I doing something wrong?
