[OSM-dev] Spatial road network data sets and implementation using API

Dear all:
Please suggest how to implement my algorithm on real ASYMMETRIC road
network datasets to get results.
I' m doing 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
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

Thanks and regards

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.
