Official code for the paper 'A Fast Hybrid Spatial Index with External Memory Support (FHSIE)' https://ieeexplore.ieee.org/abstract/document/10148115

How to use

  1. boost homepage: https://www.boost.org/

  2. Change path change {boost_1_78_0/include's root} to your own path

Dataset

Download the dataset from the link https://drive.google.com/file/d/1uAq8O0rPLHV5eGOPEXi5Jol0JcN_tHvQ/view?usp=sharing decompress the file, and put dataset, workload and model to FHSIE

Parameter Settings

16M: level_num=4; level_custer[level_num] = {20,20,20,20}; 256M: level_num=4; level_custer[level_num] = {40,40,40,40};

Running code

{reaplce /home/suzy/boost_1_78_0/include with your own boost_1_78_0/include's root} {reaplce /home/suzy/boost_1_78_0/lib with your own boost_1_78_0/lib's root}

  1. Runing the utils.cpp and Constant.cpp g++ -O3 -std=c++14 -o utils.o -c utils.cpp -g -I/home/suzy/boost_1_78_0/include g++ -O3 -std=c++14 -o Constants.o -c Constants.cpp -g -I/home/suzy/boost_1_78_0/include

  2. Running AKS to build the embedding, we upload an index on skewed_16m, if you just want to check the query, you could skip this step g++ -O3 -std=c++14 -o AKS.o -c AKS.cpp -g -I/home/suzy/boost_1_78_0/include g++ -O3 -std=c++14 -o AKS AKS.o Constants.o utils.o -I/home/suzy/boost_1_78_0/include -lpthread -L/home/suzy/boost_1_78_0/lib -lboost_filesystem ./AKS

  3. Running {query type}_query.cpp to conduct query An example of point query: g++ -O3 -std=c++14 -o point_query.o -c point_query.cpp -g -I/home/suzy/boost_1_78_0/include g++ -O3 -std=c++14 -o point_query point_query.o Constants.o utils.o -I/home/suzy/boost_1_78_0/include -lpthread -L/home/suzy/boost_1_78_0/lib -lboost_filesystem ./point_query

For window and knn query, we replace the point_query with window_query and knn_query, repectively.
