comment How to apply a specific Rendering to an Image and export to JPEG?
This works for me, except for one small thing. My IMG is 250 px*250 px. I want to make a Jpeg of twice that dimensions, i.e. 500px*500px. Can you tell me how I could do this?

comment How to export a shape polygon to a file
what do you mean by file? Shapefiles are files. Do you mean a specific format? if so which format? What GIS software are you using?

comment Sorting points to flight path route
Sorry If I came off rude; That wasn't my intention. I'm trying to say that your requirement is vague. Even with the latest image, I can think of several lines that could be drawn. It might be easiest to solve, if you could manually number the points. Code could then be written which creates a line based on the numbering that you have provided.

comment What are the equivalents of ESRI products in open source for Web Mapping?
Unfortunately, Open Source is not an Monolithic entity like ESRI, and there isn't one single place where you could get all the information. You need to search at various locations and individual websites. The closest you could get is a site like GIS.Stackexchange, which has information about various different softwares.

comment Sorting points to flight path route
When we are dealing with computers, we need to tell them exactly what to do. your current requirement is rather vague. snake like path can mean different things in different contexts. Do you always have an exact rectangular array of points? You need to give more details, and need to be more specific than this. What attributes do your points have? Do you want to do this only on the basis of geometry? what have you tried so far? where are you stuck?

comment Sorting points to flight path route
what is the Logic behind this route? How do you know that the path should start at 5, and not at 1? Once you figure out that logic, we can then look into implementing it.

comment Building a road path using openlayers and shapefiles?
could you explain why you have decided to use ruby and mongo db? what was the rationale for that? There are pre existing solutions in other technologies that have already been developed and widely used. You don't have to reinvent the wheel.
