arcgislayers 0.3.1

Bug fixes

• page_size resulted in error due to introduction of type-check. Fixed and added test to avoid in the future. #205
• Add warning if arc_select() results include fewer features than expected from request #220

New features

• arc_raster() gains an argument raster_fn which takes a character scalar and performs a raster function server side before returning results
• list_service_raster_fns() is a new helper function to list available raster functions for an ImageServer
• arc_open() ignores queries included in input URLs and retains any custom queries in the query attribute for Table and FeatureLayers. (#215)

Breaking changes

arcgislayers 0.3.0

• arc_open() will now work on any resource that works when f=json is set in the query parameters closes #163
• Now uses {arcpbf} when a layer supports protocol buffers.
  • This is an ~3x speed improvement over json processing.
• New query_layer_attachments() and download_attachments() help you access and download attachments to a layer
• arc_raster() now downloads the exported image to a temp file instead of creating a connection to the url returned. This fixes an issue where rasters would stop working after the url had been removed.
• Add alias argument to arc_read() allowing replacement or labelling of field names with alias values (#169)
• Add pull_field_aliases() utility function
• arc_select() now uses arcgisutils::rbind_results() for faster row-binding if {collapse}, {data.table}, {vctrs} are installed (#175)
• Preserve order of fields column names for arc_select() (fixes minor bug with arc_read handling of col_names) (#185)
• Set CRS for a FeatureLayer or ImageServer using "wkid" or "wkt" value if "latestWkid" is missing. (#188)
• Fix issue with arc_select() when layer can’t support pagination. (#191)

arcgislayers 0.2.0

• initial CRAN release

arcgislayers 0.1.0

• arc_open() no longer removes NULL properties h/t @elipousson

• includes page_size argument to arc_select() allowing users to return smaller page sizes and avoid timeouts for dense geometries

• Add support for GroupLayers

• Add arc_read() with support for name_repair argument using {vctrs} (#108)

• Add get_layer_estimates() to retrieve estimate info such as the number of features and the extent of the layer

• Add truncate_layer() to support truncate and append workflow

• Add support for opening MapServers https://github.com/R-ArcGIS/arcgislayers/pull/83

• arc_open() with a layer that does not support Query sets the n attribute toNA https://github.com/R-ArcGIS/arcgislayers/pull/83

  • Print method will show something like <FeatureLayer <NA features, 10 fields>>

• arc_select() is now supported for ImageServers #78

• add_features() is now paginated and performed in parallel. It gains an argument chunk_size which determines the maximum number of rows to be added to a feature service.

• adds get_layers() which can fetch multiple items from a FeatureServer or MapServer

  • new utility function list_items()

• adds cli as an explicit import (has been implicitly imported by httr2)

• repository made public

• add lifecycle badges to all exported functions https://github.com/R-ArcGIS/arcgislayers/pull/101

• Breaking:

  • token arguments are required to be a valid httr2_token object (strings are not supported).
  • all host arguments are removed. Instead, the host is fetched from the token.
  • all user arguments are removed. Instead, the username is fetched from the token. If it is not found, an error is thrown.

These binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
