Sir I got stuck since last 4 months to implement my algorithm on real ASYMMETRIC road network datasets to get results. I have started research work to address LBS queries like NN, k-NN,ANN, ..... I'm very much confused that I can't interpret data sets as it is given in various uncommon/unknown file format. I believe that I need data sets in the form <longitude, latitude=""> pair for n POI on real road network(spatial data), so that when I give <longitude, latitude=""> of my input query point q, it should find NN, k-NN... In addition we also need directed graph data sets for asymmetric road network where d(a,b) != d(b,a). So, I need step-by-step guidance to implement and test my algorithms in the following contexts a) data sets collection and interpret/Extracting Spatial Data(say from OpenStreetMap) b) implement/simulate a prototype library/framework of LBS queries c) Implement/simulate prototype applications on top of the library so that we can get results of our experiments

I suggest you pick a consultant from the list in our wiki and ask them to help you. What you are asking for (step-by-step guidance on a very specific project) is beyond the kind of help we can provide through a Q&A site like this one.
