geojsonio (development version)

geojsonio 0.11.2

  • This is a tiny patch release with no user-facing changes.

  • Added \alias{geojsonio-package} to man/geojsonio.rd.

geojsonio 0.11.1

  • Removed references to geojsonlint as that package nears retirement.

geojsonio 0.11.0

Breaking changes

  • SpatialPolygonsDataFrame inputs are now cast to sf before being written out to fix ring ordering. This was previously handled by maptools, which is being retired. Outputs are visually identical, but underlying representations may have changed.
  • Functions relying on rgeos (such as those writing rgeos objects to file) are defunct. PRs to replace these using the newer geos package are welcomed.

New features

  • topojson_write() has been restored, and now supports conversion to topoJSON formats. User reports indicate output files might be larger than anticipated; PRs to address this are welcomed. Huge thanks to @Shaunson26 for this PR!

Other changes

  • The rgeos and maptools packages have been removed from Imports. (Thanks to Roger Bivand and Mike Sumner on Mastodon!)

geojsonio 0.10.0

  • Deprecated (with a warning) functions relying on rgeos. These will stop working in 2023.
  • Tests have been updated to use testthat 3e, plus a number of other improvements around isolating tests and improving test quality. HUGE thanks to @czeildi for tackling this in two massive PRs (#187, #186, #183).

geojsonio 0.9.5

geojsonio 0.9.4

BUG FIXES

  • fix for sprintf() usage within the projections() function; only run sprintf on a particular string if it has length > 0 (#172)
  • fix for as.json() when the input is the output of topojson_list() - we weren't constructing the TopoJSON arcs correctly (#160)
  • fix to geojson_read(): now using package geojsonsf to read geojson (#163)

geojsonio 0.9.2

BUG FIXES

  • fix a test for change in stringsAsFactors behavior in R v4 (#166) (#167)
  • temporarily make topojson_write() defunct until we can sort out issues with new sf version (#168)

geojsonio 0.9.0

NEW FEATURES

  • geojson_sf() and geojson_sp() now accept strings in addition to json, geoson_list and geojson_json types (#164)

MINOR IMPROVEMENTS

  • topojson_json() and topojson_list() gain params object_name and quantization to pass through to geojson_json() (#158)
  • replace httr with crul (#105)
  • rgdal replaced with sf throughout the package; all writeOGR replaced with st_write and readOGR with st_read; this should not create any user facing changes, but please let us know if you have problems with this version (#41) (#150) (#157)

geojsonio 0.8.0

NEW FEATURES

  • geojson_read() gains new S3 method geojson_read.PqConnection for connecting to a PostgreSQL database set up with PostGIS. See also ?postgis for notes on Postgis installation, and setting up some simple data in Postgis from this package (#61) (#155) thanks to @fxi

MINOR IMPROVEMENTS

  • geojson_read() instead of going through package sp now goes through package sf for a significant speed up, see ropensci#136 (comment) (#136)
  • geojson_list() gains parameter precision to adjust number of decimal places used. only applies to classes from packages sp and rgeos (#152) (related to #141) thanks to @ChrisJones687
  • improve dependency installation notes in README (#149) (#151) thanks @setgree and @nickto
  • move to using markdown docs
  • file_to_geojson() now using https protocol instead of http for the online ogre service called when using method = "web"

BUG FIXES

  • fix geojson_read() to fail better when using method="web"; and update docs to note that method="web" can result if file size issues, but method="local" should not have such issues (#153)
  • change name of print.location method to not conflict with dplyr (#154)

geojsonio 0.7.0

NEW FEATURES

  • geo2topo() gains a new parameter quantization to quantize geometry prior to computing topology. because topojson_write() uses geo2topo() internally, topojson_write() also gains a quantization parameter that's passed to geo2topo() internally (#138) thanks @pvictor

MINOR IMPROVEMENTS

  • use package sf instead of sp in topojson_read(). note that the return object is now class sf instead of classes from the sp package (#144) (#145)
  • the type parameter in topojson_json() now set to type="auto" if the input is an sf/sfc/sfg class object (#139) (#146)
  • fix to geojson_list.sfc() for changes in sf >= v0.7, which names geometries, but that's not valid geojson (#142)

DEPRECATED AND DEFUNCT

  • The two linting functions in this package, lint() and validate() are now defunct. They have been marked as deprecated since v0.2. See the package geojsonlint on CRAN for linting geojson functionality (#135) (#147)

geojsonio 0.6.0

NEW FEATURES

  • topojson_write() gains a new parameter object_name. With it you can set the name for the resulting TopoJSON object name created. As part of this geo2topo() also gains a new parameter, similarly called object_name, that does the same thing as for topojson_write(). (#129) (thanks @josiekre) PR (#131)
  • As part of PR (#132) we added a new function geojson_sf() to convert output of geojson_list() or geojson_json() to sf package classes - as an analog to geojson_sp()

MINOR IMPROVEMENTS

  • geojson_json() gains option with the type parameter to skip a coercion to the geojson package class geoclass. Using type = "skip" you can skip the geoclass class coercion, which in some cases with large datasets should have performance improvements (#128) PR (#133)

BUG FIXES

  • A bug arose in geojson_sp() with the newest version of rgdal. This was resolved by using the sf package instead to read GeoJSON. This had a knock-on benefit of speeding up reading GeoJSON. In addition, sf is now in Imports instead of Suggests (#130) PR (#132)

geojsonio 0.5.0

NEW FEATURES

  • gains new function geojson_atomize to "atomize" a FeatureCollection into its features, or a GeometryCollection into its geometries (#120) via (#119) thx @SymbolixAU
  • gains new functions topojson_list and topojson_json for converting many input types with spatial data to TopoJSON, both as lists and as JSON (#117)
  • geojson_json uses brief output provided by the geojson package - this makes it less frustrating when you have an especially large geojson string that prints to console - this instead prints a brief summary of the GeoJSON object (#86) (#124)

MINOR IMPROVEMENTS

  • doing a much more thorough job of cleaning up temp files that are necessarily generated due to having to go to disk sometimes (#122)
  • @ateucher made improvements to geojson_json to make type parameter more flexible (#125)

BUG FIXES

  • Fixe bug in topojson_write - we were writing topojson file, but also a geojson file - we now cleanup the geojson file (#127)

geojsonio 0.4.2

BUG FIXES

  • Fix package so that we load topojson-server.js from within the package instead of from the web. This makes it so that the package doesn’t make any web requests on load, which prevented package from loading when no internet connection available. (#118)

geojsonio 0.4.0

NEW FEATURES

  • Gains new functions geo2topo, topo2geo, topojson_write, and topojson_read for working with TopoJSON data - associated with this, we now import geojson package (#24) (#100)

MINOR IMPROVEMENTS

geojsonio 0.3.8

MINOR IMPROVEMENTS

  • geojson_write and geojson_json now pass ... argument through to rgdal::writeOGR or jsonlite::toJSON depending on the class/method. For those methods that use the latter, this now allows setting of the na argument to control how NA values are represented in json, and the pretty argument to control whether or the resulting json is pretty-formated or compact (#109) (#111)
  • Spelling/grammar fixes, thanks @patperu ! (#106)

BUG FIXES

  • geojson_json and geojson_write now convert unsupported classes to their basic class before conversion and/or writing to geojson. This was most commonly occurring with fields in sf objects calculated by sf::st_area and sf::st_length which were of class units. (#107)
  • Fixed a bug occurring with GDAL version >= 2.2.0 where the layer name in a geojson file was not detected properly (#108)

geojsonio 0.3.2

BUG FIXES

  • Fix to tests for internal fxn convert_wgs84 to do minimal test of output, and to conditionally test only if sf is available (#103)

geojsonio 0.3.0

NEW FEATURES

  • geojson_json, geojson_list, and geojson_write gain new S3 methods: sf, sfc, and sfg - the three classes in the sf package (#95)
  • geojson_json, geojson_list, and geojson_write gain two new parameters each: convert_wgs84 (boolean) to convert to WGS84 or not (the projection assumed for GeoJSON) and crs to assign a CRS if known (#101) (#102)

MINOR IMPROVEMENTS

  • geojson_json() for non-sp classes now only keeps seven decimal places in the coordinates. This follows the default that GDAL uses.
  • Now namespacing base package calls for methods/stats/utils instead of importing them
  • Improved documentation for method parameter in geojson_read clarifying what the options are for (#93) thanks @bhaskarvk
  • Internal fxn to_json now defaults to 7 digits, which is used in as.json and geojson_json (#96)

BUG FIXES

  • Fix to geojson_read to read correctly from a URL - in addition to file paths (#91) (#92) thanks @lecy
  • Fix to geojson_read to read non-.geojson extensions (#93) thanks @bhaskarvk

geojsonio 0.2.0

MINOR IMPROVEMENTS

  • Major performance improvement for geojson_json() - moved to reading in json with readr::read_file() (#85) thanks @javrucebo !
  • Now requiring explicit versions of some package dependencies
  • Removed the startup message

BUG FIXES

  • Changed file_to_geojson() to use httr::write_disk() instead of download.file() (#83) thanks @patperu

DEPRECATED AND DEFUNCT

  • The two linting functions in this package, lint() and validate() are now deprecated, and will be defunct in the next version of this package. See the new package geojsonlint on CRAN for linting geojson functionality (#82)

geojsonio 0.1.8

NEW FEATURES

  • New method geojson_sp.json() added to geojson_sp() to handle json class inputs

MINOR IMPROVEMENTS

  • Added encodin="UTF-8" to httr::content() calls

BUG FIXES

  • geojson_write() didn't overwrite existing files despite saying so. New parameter added to the function overwrite to specify whether to overwrite a function or not, which defaults to TRUE (#81) thanks @Robinlovelace !

geojsonio 0.1.6

NEW FEATURES

  • New function geojson_sp() to convert output of geojson_list() or geojson_json() to spatial classes (e.g., SpatialPointsDataFrame) (#71)

MINOR IMPROVEMENTS

  • Startup message added to notify users to ideally update to rgdal > v1.1-1 given fix to make writing multipolygon objects to geojson correct (#69)
  • Filled out test suite more (#46)

BUG FIXES

  • Fix to lint() function, due to bug in passing data to the Javascript layer (#73)
  • Fixes to as.json() (#76)

geojsonio 0.1.4

NEW FEATURES

  • New function map_leaf() uses the leaflet package to make maps, with S3 methods for most spatial classes as well as most R classes, including data.frame's, lists, vectors, file inputs, and more (#48)
  • geojson_read() now optionally can give back a spatial class object, just a convenience in case you want to not get back geojson, but a spatial class (#60)

MINOR IMPROVEMENTS

  • Now that leaflet R package is on CRAN, put back in examples using it to make maps (#49)
  • Added a linter for list inputs comined with geometry="polygon" to all geojson_*() functions that have .list methods. This checks to make sure inputs have the same first and last coordinate pairs to close the polygon (#34)

BUG FIXES

  • Importing all non-base R funtions, including from methods, stats and utils packages (#62)
  • Fixed bug in geojson_write() in which geojson style names were altered on accident (#56)

geojsonio 0.1.0

NEW FEATURES

  • released to CRAN
