Issue

@Ned-Laman-NOAA

There is a gap between AI and GOA stratum shapefiles to the west of Umnak.

library(akgfmaps)

slope_layers <- akgfmaps::get_base_layers(select.region = "ebs.slope", set.crs = "EPSG:3338")
ebs_layers <- akgfmaps::get_base_layers(select.region = "ebs", set.crs = "EPSG:3338")
goa_layers <- akgfmaps::get_base_layers(select.region = "goa", set.crs = "EPSG:3338")
ai_layers <- akgfmaps::get_base_layers(select.region = "ai", set.crs = "EPSG:3338")
chukchi_layers <- akgfmaps::get_base_layers(select.region = "ecs", set.crs = "EPSG:3338")
ebs_survey_bathy <- akgfmaps::get_survey_bathymetry(select.region = "ebs", set.crs = "EPSG:3338")

survey_regions <- dplyr::bind_rows(
  dplyr::filter(ebs_layers$survey.strata, SURVEY == "EBS_SHELF"),
  dplyr::mutate(slope_layers$survey.strata,
                SURVEY = "EBS_SLOPE"),
  dplyr::mutate(ai_layers$survey.strata,
                SURVEY = "AI"),
  dplyr::mutate(goa_layers$survey.strata,
                SURVEY = "GOA")
)

I'm aware of this issue and we are beginning to discuss with Mark Zimmermann the re-gridding of the Gulf and Aleutian survey areas to address this and other issues related to these historical and non-reproducible sampling grid systems. This discussion extends beyond the Groundfish Program to include OFIS and database/data management activities for things like supporting our enterprise ESRI ArcMap capabilities along with our enterprise Oracle data storage and application issues.
