I wrote this small program, following the boost documentation, but I get pages of errors when building it. Here is the build: ...
I am kinda confused and think I get something wrong but I really fail to see it. I have a boost::geometry::index::rtree that stores 2D boxes of 2D ge ...
I have two files: header.h and code.cpp, I can not write any boost namespace on code.cpp, so all "boost::geometry::etc..." calls go on header.h. The i ...
I am currently using Geopandas, and I need to search for the k-nearest neigbour efficiently in a data frame. According to the documentation, the imple ...
My code is The error message Basically I have similar error with this ImportError: Spatial indexes require either `rtree` or `pygeos` in geopan ...
I have a built boost rtree: I can iterate through leaf nodes: I can get root bounds: But how can I get other level bounds ? There is no bound ...
I would like to continue using Room, but I see no way to create an Entity that uses rtree. There is @FTS3 and @FTS4 annotations but nothing for RTree ...
I am having some difficulty understanding how to draw an R-tree of 2D rectangles from a picture of its structure. I have quickly drawn a sketch of som ...
Given a defined (lat, lon) geo-point I'm trying to find in which polygon this point lies in. I suppose iterating over all the polygons is not efficien ...
There are two shapefiles. And I have extracted those two data using geopandas file. and it was successful. Now I want to look for the intersecti ...
TLDR: is there a way to update object directly in a Boost r-tree (by setting the location class property to const, or something similar)? More info: ...
As Here said: "In version 3.4 they introduced SASI indexes (SSTable Attached Secondary Indexes). Basically a portion of the index is associated to eac ...
I am using Boost's r-tree implementation in my code. I have a list of objects with coordinates (say cities on a map, if it matters), which I wish to i ...

I have a surface mesh of triangles. Assume, the surface mesh is closed. I intend to do a spatial query to figure out whether a space is within my s ...
We have a scenario where we dynamically grow a memory mapped file used for boost's r-tree geometric index. We also make use of boost's interprocess me ...
Here introduces how to boost spatial intersection queries using R-Tree. Here @JHuw provides ways using R-Tree to calculate the nearest distance from p ...
After reading this article https://www.sqlite.org/rtree.html about the R*Tree in SQLite, i am currently experimenting with a 2-Dim R-Tree in a Core Da ...
