Extracting approximate point to point cost using osrm

Code is WIP

This code is work in progress and is to change frequently.

What is it

Right now, provide a bbox and cost between all geohash pairs of given precision in it will be extracted. If cost is distance i.e. your osrm config uses distance it gets same

Creating Development Environment

You need to install these tools using standard utils.

• cmake 3+,
• clang++/gcc5 ( supporting C++14)
• autoconf automake etc ( for thirdparty tools )
• glog and gflags.
• libosrm

Compiling

You need to have libosrm , follow the instructions on https://github.com/Project-OSRM/osrm-backend

Create a build directory

mkdir build
cd build
# Debug
cmake -DCMAKE_BUILD_TYPE=Debug .. && make
# Release
cmake .. && make

Running

This can run with ch or mld files, bbox uses (left,bottom,right,top) I usually use the excellent tool at http://norbertrenner.de/osm/bbox.html

./fawcet_main -btype bbox -prec 5 -data 77.469,12.813,77.789,13.085 --mldfile mld_filename.orsm 
./fawcet_main -btype bbox -prec 5 -data 77.469,12.813,77.789,13.085 --chfile ch_filename.orsm

Sorry

... for the sparse documentation, I will make a more detailed description when time permits.
