# Geo This is a library for dealing with geo positions and areas.

# Changelog ### 2.5.0 - Enhancement: Export the function `coordinateToString` which takes a position as hours, minutes, seconds and latitude/longitude, then returns a string representation of its input. - Chore: update abseil/s2 external dependencies. #### 2.4.3 - Fix: omit logging of error messages; e.g. if an invalid rect is provided to `region`, the function yields `?None`, but we do not want a message on the console. #### 2.4.2 - Enhancement: update underlying libraries (s2, abseil) to profit from bugfix in abseil. #### 2.4.1 - Enhancement: update underlying libraries (s2, abseil) to profit from performance improvements and possible bugfixes. ### 2.4.0 - Feature: add `<` instance for `:: CircleRegion` to `Data.Geo.Ord`. #### 2.3.1 - Chore: accept `base` `3.0`. #### 2.3.0 - Feature: add `==` instances and `genShow` derivations for `RectRegion` and `CircleRegion`. #### 2.2.3 - Chore: add dependencies on generic-print, json and posix to make compilation test succeed. #### 2.2.2 - Chore: Support base ^2.0. #### 2.2.1 - Chore: update `s2geometry` and `abseil-cpp` dependency. ### 2.2.0 - Feature: add `Data.Geo.GenHash` providing `gHash` instances for all types defined in `Data.Geo`. ### 2.1.0 - Feature: add `genShow`/`ggen` instances of `Region` and `RegionValue`. - Fix: `instance < Position`. ## 2.0.0 - Change: Check that latitude and longitude are in the correct range when generating Position values. Requires to change the type of `position` to result in a `MaybeError` value. #### 1.1.2 - Fix: bug in `rectRegionToBoundaryLines` causing erroneous lines to be returned by the function for the west/south boundaries. #### 1.1.1 - Chore: switch to `abseil-cpp` branch `lts_2022_06_23`. ### 1.1.0 - Feature: add function to create lines and check if the lines intersect with other lines or if the lines intersect with the boundary lines of a `:: RectRegion`. #### 1.0.2 - Chore: upgrade base-compiler-itasks version constraint from =1.0.0 to ^1.0.0 || ^2.0.0 #### 1.0.1 - Robustness: add triangle inequality property to `Data.Geo.distanceBetween` ## 1.0.0 - Initial version
