Automatic numeric attribute accumulation does *not* apply to attributes
that have an explicit attribute accumulator set, because the order of
operations is too messy and weird
* Another try at fixing longitude wraparound for bins
* Gonna get it right this time
* Forgot to update the comment
* The filter case was not supposed to reinterpret geometry
* Copy antimeridian-crossing geometries to the other side too
* Getting closer to getting antimeridian-crossing polygons right
* Update changelog and version
* Factoring out tilestats management from GeoJSON file reading
* Move code around so overzoom can link against parse_layers
* Read the file of bins
* Plumb the bins through to overzoom()
* Some zip code bins to test with
* (Currently non-functional) test of binning
* Starting to spell out the bin matching loop
* Can't flatten points, so don't flatten bins either
* More fleshing out bin traversal
* Bounding box of tile-relative mvt geometry
* Smallest enclosing tile from bbox
* Most of the bin scan
* Add point in polygon check. It crashes.
* Find the matching bins
* GDAL-style bounding boxes have eaten my brain
* Make some features to bin into
* Increment a count as features are found to be within the bins
* Fix longitude wraparound in overzoom bins
* Fix the tests
* Push off attribute copying until after bin assignment
* Carry sum of numeric attributes into the bins
* Also add mean, min, and max
* Add --calculate-feature-index since I keep needing it for testing
* Add an option to accumulate sum/mean/max/min/count of all numeric attrs
* Don't bake in tippecanoe:mean, since we redo it from sum and count
* Forgot to update this test fixture after removing tiled mean
* Update version and changelog
* Replace build-essential in Docker builder image
build-essential is overkill, it pulls in all of the tools one needs to
make to build debian packages, which we are not doing. Even though this
is a builder image, it still takes time to download all the extra crud.
Replace build-essential with make gcc and g++, which are all that are
needed.
* Replace dev packages in final Docker image
The dev packages are only needed in the builder image. They add header
files and docs and things that are not needed in the final image.
Removing them and replacing them with just the runtime libraries reduces
the final image size by about 25% (160M->124M) in a local build.
Additionally, just for simplicity, zlib1g is already part of base
ubuntu minimal, so we don't even have to list it.
* Remove build-essential mention from the README
Just like the in Dockerfile, people don't need all of those packages
to build directly on their system.
* Clip before dealing with multiplier or filters in overzoom
* Be more careful to retry when the feature count is exceeded
* Adjust the estimated total feature count for the multiplier too
* Fix the feature count estimates, I think
* Pass build info into the version string
* Report the actual max zoom of any tiles as the metadata maxzoom
* Revert unneeded renaming to make the diff more readable
* Clean up the adjustments to tile sizes and feature counts
* Update version and changelog
* Dropping a feature into a multiplier cluster still effectively drops it
* Update changelog
* Rethink the changelog description
* Don't try to truncate zooms if we are still tiling at z18
* Track output position at the file level instead of within each tile
* Track file position where the child tile data begins
* Add option and document its intended behavior
* Changing the detail loop to account for stopping early
* I forgot I already added an option for this
* Stop early if we can make a complete tile
* Add a test of zoom truncation with limited feature count
* Forgot to commit the actual code change
* Make room for a vertex count in the header of each serialized tile
* Estimate tile complexity; don't try truncating when unlikely to work
* Be more conservative, because ever retrying a tile is a big speed hit
* If stopping early, don't simplify or clean; leave that to overzoom
* Add tiny polygon reduction / dust to overzoom
* Don't try to stop early in the children if we dropped anything by rate
* Fflush here too before pwriting
* Don't stop early if we ended up dropping any features.
Rework the can-the-next-zoom-stop-early logic to avoid going
one zoom further than needed.
* Fix warning
* Fix warnings
* Oops, checking for the wrong expected return value
* Cleanup from adding line simplification in overzoom
* Current (wrong) behavior when combining coalescing and truncating
* Keep a list of parent tiles to skip rather than truncating
* Now the coalesced tiles in z12 get children in z13
* Don't double-count feature dropping when the zoom level is retried
* Correct README description
* Remove todo about special case below basezoom, which is accounted for
* Be a little more aggressive in drop-densest determination
* Scale tile feature limit for megatiles in the same way as byte limit
* Fully deprecate -detect-shared-borders into an alias
* Track the distances found in the douglas-peucker recursion
* Serialize and deserialize the distance with the vertices
* Revert "Serialize and deserialize the distance with the vertices"
This reverts commit 753f1b7909.
* Revert "Track the distances found in the douglas-peucker recursion"
This reverts commit e5361f8c22.
* Revert "Fully deprecate -detect-shared-borders into an alias"
This reverts commit 0698aeb766.
* Better tracking of whether we failed to make a full-detail tile
* Put a bloom filter in front of the binary search for shared nodes
* Forgot to take out this printf
* Improve dispatch of tiling tasks
* Still dispatch the biggest tasks first
* Track zoom truncation in the strategies list in the tileset metadata
* Prescan for small deltas before doing proper simplification
* Revert "Prescan for small deltas before doing proper simplification"
This reverts commit d1d8238b83.
* Update version and changelog
* Rename to --generate-variable-depth-tile-pyramid
* Reviving multi-source-tile overzoom: the clip.cpp side
* Reviving multi-source-tile overzoom: the overzoom.cpp side
* Update readme
* Update version and changelog
* Start to distinguish fixed cluster density setting from as-needed density
* Make consistent {drop,coalesce}-densest decisions between zooms
* Actually track the previous index instead of just intending to
* Clean up collinearities in coalesced features
* To determine densest, look at actual physical distance, not just index
* Don't actually need the previous index in serial_feature now
* Center of mass of one feature to most distant point of the next
* Add apologetic comment
* Wait, how did the tests pass before?
* Revert "Wait, how did the tests pass before?"
This reverts commit f73c8ee543.
* Add --maximum-string-attribute-length option
* Update version and changelog
