Spatial Data Functions

Description

These functions allow for analysis and manipulation of spatial data. Tasks include but are not limited to analyzing polygons, comparing projections, and checking data compatibility.

Usage

polyfix.sf(x)

build.prj4str(
  prj,
  datum = NULL,
  ellps = NULL,
  zone = NULL,
  zoneS = FALSE,
  aea.param = "USGS",
  gui = FALSE
)

trunc10shp(x)

merge_extents(layer1, layer2)

check.extents(
  bbox1,
  bbox2,
  showext = FALSE,
  layer1nm = NULL,
  layer2nm = NULL,
  stopifnotin = FALSE,
  quiet = FALSE
)

getprjatt(prj4str, prjatt, stopifnull = FALSE)

areacalc.poly(
  polyv,
  polyv_dsn = NULL,
  areaprj = "aea",
  zone = NULL,
  unit = "ACRES",
  areavar = NULL
)

checksf.longlat(x, nolonglat = TRUE, crs.default = NULL)

crsCompare(
  x,
  ycrs = NULL,
  x.crs = NULL,
  nolonglat = FALSE,
  checkonly = FALSE,
  crs.default = NULL
)

sf_dissolve(sflayer, col = NULL, areacalc = TRUE)

closest_poly(x.centroid, ypoly, ypoly.att = NULL, nbr = NULL, returnsf = TRUE)

getIntersect(layer1, layer2, layer1.unique, layer2fld, overlapThreshold = 0)

clip.othertables(
  inids,
  othertabnms,
  othertabs = NULL,
  uniqueid = "PLT_CN",
  savedata = FALSE,
  outfn.pre = NULL,
  outfolder = NULL,
  out_fmt = "csv",
  out_dsn = NULL,
  outfn.date = FALSE,
  overwrite_layer = FALSE,
  gui = FALSE
)

check.area(bnd, bnd_dsn, bnd.att = NULL, areaunits = "acres", min.area = 6000)

Details

These functions carry out spatial data analysis.

Value

Spatial data object from 'sf'. Used for spatial data analyses.
