comment Geodjango - User's uploaded shapefiles and model creation
Seeing that this question has recieved some interest lately I just want to point out that PostgreSQL now supports schemaless data, using json or hstore (postgresql.org/docs/9.1/static/hstore.html)

comment How to link a text to a map
Yes, it's possible. (This was what you asked, but probably not the answer you are looking for. Please put some more effort into phrasing your question, give us an idea of what you've tried so far and other relevant information.)

comment A mistake in very easy python code (Buffer 1 - Buffer 2- Erase 2 fom 1)
could you tag this with a less general tag than python in addition? This seems to be arcpy, so tag accordingly

No, I do not think Geoserver has a notion of "right rendering order"

comment Setting properties of geoJSON in OpenLayers
Setting a new property on a vector feature is done with set(): openlayers.org/en/v3.1.1/apidoc/…

As for problem 2: I missed your first defition of feature, but renaming it should be easy..

comment Setting properties of geoJSON in OpenLayers
For problem 1) these objects are not copied when assigned to a new variable, the reference is passed. That means that if i loop through Layer2Source, extract feature i, assign it to a variable, push that variable into a new array, and then get it back out from that array and assign it to a new variable it's still the same object as the original one

comment Using raw_input python to accept string with a dash (-)
Consider adding a less generic tag in addition to Python here, this looks like some sort or arcpy-thing?

comment Files generated with QGIS are invisibles for my system (windows 8.1) How can I Solve this?
Welcome to GIS SE. While I cannot help you directly I feel that there is a bit too little context here. Are you sure you are looking in the right folder?

comment OpenLayers FrameCloud does not find JavaScript functions
Ah, i didn't expect to find an onclick event in there. FYI: onClick should be avoided, and given the state your code is in I cannot really give a better answer than look up jQuery or some other sane frameworks.

comment Selection instead of click for display of features in openlayers
What you are asking is simply not possible with WMS, regardless of whether you set a bounty or not. If you want to query individual features using a BBOX you have to use something vector-based, WFS seems like the easiest solution for you

comment ogr2ogr window closes after termination
When you have such questions you shouldn't assume that people know that you are on Windows (but again, most do, because this is a windows-issue). But again: as AndreJs answer illustrates, stating what windows version you are using would be helpful

comment How do the equations/algorithms behind buffering tools actually work?
Just to be smirky: jsjts is really java implemented using javascript, so it's about the same ;)

comment How to calculate the Azimuth between two points in PostGIS?
Not an actual answer to your question, but since you mentioned "computing azimuth" and "JavaScript" I thought you want to look at github.com/atlefren/holsenjs, a port of Geodetic Fortran code to JavaScript. To compute asimuth between the points mentioned below: var holsen = new Holsen(); holsen.setEllipsoid('wgs84'); var asimuth = holsen.lgeo2(-0.730, 55.578, 37.062, 55.578).A1;

comment Is there a good GPS track analysis library?
Just a follow-up here: I've started porting this project to Python, using Shapely and GeoAlchemy (and Flask), it works but is rather slow at the moment. Code at github.com/atlefren/mineturer2 for the curious

comment How to insert coordinates to url
thanks for noticing! No, not really, I'm not an expert on this, so maybe pushState would be better?

Learn Javascript. Understand why global variables is a bad thing, provide a minimal example. Study the docs.
