Erica Fischer 4ef430b913 Add an option for the Visvalingam simplification algorithm (#16) 
* First attempt at porting Paul Mach's Visvalingam implementation

* Make indent

* Mostly working

* Approximate equivalence from Douglas-Peucker to Visvalingam levels

* Don't simplify away tile boundary crossing points

* Add a command-line option and test for Visvalingam simplification

* Update changelog

* Cleanup in response to review feedback

* Include <stdio.h> to fix compiler warnings

Erica Fischer 6de00c15ec Fix tests that I missed updating in 2.6.2 (#15) 2022-09-27 10:37:02 -07:00
Erica Fischer 3086838a10 Fix wrong-way comparison that was causing buffer overflow crash in tile-join (#14) 
* Fix wrong-way comparison that was causing buffer overflow in tile-join

* Update changelog
 2022-09-27 09:15:54 -07:00
Erica Fischer af1a7ed7ae Once features can't possibly fit in a tile, stop trying (#9) 
* Stop adding features to a tile if it can't possibly work

* Add --integer and --fraction options to tippecanoe-decode

* Carry the strategies field from tileset metadata through tile-join

* Update changelog

* Assign different codes to different kinds of error exits
 2022-09-23 20:01:13 -04:00
Erica Fischer 8e46650da7 Upgrade to protozero 1.7.1 (#5) 
* Upgrade to protozero 1.7.1

* Bump version number
 2022-09-13 11:24:01 -07:00
Erica Fischer 073700aa38 Reduce maxzooms being guessed a little: (#2) 
* Reduce maxzooms being guessed a little:

* Use 1.5 standard deviations, not 2, as the minimum distinguishable
* Give overlapping polygons and linestrings more distinct indices

* Add another drop rate guessing options, from the same metrics -zg uses

* Guard against using -rp without -zg
 2022-09-08 15:47:32 -07:00
Erica Fischer a447dfc089 Extra coordinate precision; feature ordering; compression improvements 
* Add an option to retain extra coordinate precision at maxzoom

* Make sure not to shift away the extra detail from coordinates

* Add an option to convert double-precision attributes to single

* Sort attribute values in tiles to make them compress a little better

* Slightly improve polygon simplification

By choosing a point that would be retained after simplification
to be the start/end point that always gets retained

* I regret making all of these tests involve polygons

* Add an option to specify the size of tiny polygons

* Fix accidental requiring of argument for --single-precision

* Guard against duplicate points when generating "sizes" for them

* Restore the intended behavior that tiny polygons don't get simplified

* Make the extra detail settable rather than always maximizing it

* Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)"

This reverts commit fec5e8354c.

* Add an option to prevent choosing a base zoom higher than the maxzoom

* Keep the drop rate high enough when the basezoom gets constrained

* Revert "Revert "Improve maxzoom guessing for tightly-clustered point data sources (#4)""

This reverts commit db6bc27d9e.

* Add --order-by and --order-descending options

* Accept multiple --order-by and --order-descending-by sort keys
