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
Teaching is an art and a challenge as well. It doesn't matter how much we know. What matters is how clearly others can understand what we know.
