Origins and destinations

stplanr 0.1.5

NEW FEATURES

• New argument destinations added to od2line(). See example(od2line) for an example.
• New dataset destinations for showing how OD matrix with destinations can be converted to spatial data
• New argument list_output allows the route information to be saved as a list, allowing save_raw = TRUE (which does not return a Spatial object) to be passed to the route_ function.
• tmap dependency removed for faster installs

BUG FIXES

• Bug with line2route() (#124) fixed
• Various improvements to documentation

Bearings and reprojections

stplanr 0.1.4

NEW FEATURES

• New function reproject() is a simple wrapper around spTransform() that uses
  crs_select_aeq() to convert a spatial object in geographic (lat/lon) coordinates
  into on with projected coordinates, with units of 1 m. This is useful for various
  spatial operations, such as finding the length and area of an object.
• Implement gprojected(), a function for performing GIS operations on a temporary, projected, version
  of spatial objects.
• Addition of line_bearing() to return the bearing of lines based on start and end points.
• Addition of angle_diff() for finding the angular difference between lines: are they roughly parallel or perpendicular?

BUG FIXES

• line2df() now works on lines with multiple vertices and is faster.
• Fixes in the examples used to illustrate how od_dist() works.

stplanr 0.1.3

NEW FEATURES

• Update to OSRM functions to support API v5.
• New parameter byvars in the overline() function, to allow disaggregation of results by a grouping variable (see example(overline)).
• Faster implementation of od2line(): od2line2(). Plan is to replace the original if no issues are found with new implementation.
• New function od2odf() which converts OD data into a dataframe of origins and destinations (feeds od2line2() but also useful as self-standing function).
• New argument new_proj in buff_geo() allows the results to be exported to any coordinate reference system (CRS).
• New function gprojected() generalises concept of buff_geo(), building on crs_select_aeq() to allow any GIS query to be conducted on a temporary projected version of spatial objects with geographical CRSs.
• New function od_dist() can quickly calculate Euclidean distances of OD pairs without converting to spatial objects.

BUG FIXES

• Bug fix in onewayid() so it captures all lines.
• Various improvements to documentation and code.

Google Distance Matrix

stplanr 0.1.2

NEW FEATURES

• Interface to the Google Distance Matrix API with dist_google.
• New transport planning API added, with route_transportapi_public (for testing).
• Update to line2route, allowing it to accept different routing funtions via the new argument route_fun (for testing - tested with route_fun = route_cyclestreet).
• New functions for creating origin-destination data frames (point2odf) and SpatialLinesDataFrames (points2flow).
• Addition of n_vertices and is_linepoint for identifying the number of vertices in spatial objects and whether the 'line' is really a point.

BUG FIXES

• line2route refactored, with 10 fold speed increases on large (1000+) batches of lines.

stplanr 0.1.1

This is was the first major working update on CRAN.

NEW FEATURES

• Addition of new class definition SpatialLinesNetwork, methods for plot
  and summary and functions calc_network_routes and find_network_nodes
  allowing fast route calculations via igraph and other network analysis
  functions.
• Functions for removing beginning and end of lines: toptail and
  toptailgs. Helper functions buff_geo,
  crs_select_aeq and line2points added.
• Functionality for reading in the UK's stats19 data: read_stats19_*
  functions download, unzip and re-categorise the data.
• read_table functions added for reading Australian OD data.
• decode_gl added to decode Google polylines and other functions for
  querying and reading data from OSRM services.
• gtfs2sldf added to import GTFS routes as SpatialLinesDataFrames.
