The following changes were made throughout August and September 2017, when new services were published to replace previous content:

GovUnits

• All land unit types broken out into individual layers. Rather than a single layer with "Other Reserves" that included USFS, Military, and others, each FTYPE (from GU_Reserve) has its own layer, created with definition queries. Affected layers:

  • National Park

  • National Forest

  • National Wilderness

  • Wildlife Reserve

  • National Grassland

  • National Cemetery

  • Military Reserve

  • NASA Facility

  • Metropolitan Washington Airport

  • BLM land (no labels)

  • Tennessee Valley Authority land (no labels)

  • Incorporated Place, Unincorporated Place, Minor Civil Division, Native American Area, Congressional District, County, and Large/Small-scale States remain the same.

• Layer order changed.

• Labels updated to new typeface. Most labels have their drop shadows or fills changed to be visible against newly designed layers, whether the PADUS style polygons or others.

• Labels use drop shadows instead of halos.

• Polygon fills of most national lands updated to match color scheme in PADUS viewer .

• Outlines/fills of all other features updated to be visible against new USGS Topo base map and grayscale shaded relief.

• Visibility restrictions by scale removed from all layers except States which are still divided into large-scale and small-scale layers.

• Currently, only States and Counties are on by default while all other layers will have to be manually turned on. States are visible at all scales; Counties are visible in beyond 1:600,000.

Map Indices

• Layer order changed.

• Label font and halo changed.

• Colors of 1x1 degree and 30x60 minute cells changed.

• 1x1 degree cell features are visible at all scales; 1x1 degree cell labels are visible larger than 9M in scale.

• 30x60 minute cell features are visible larger than 20M, and 30x60 minute cell labels are visible larger than 5M in scale.

• 15 minute cell features are visible larger than 4M, and 15 minute cell labels are visible larger than 2M in scale.

• 7.5 minute cell features are visible larger than 1M, and 7.5 minute cell labels are the same (visible at 577K and larger in scale).

• 3.75 minute cell features are visible larger than 500K, and 3.75 minute cell labels are the same (visible at 288K and larger in scale).

• All layers are on by default (which is same behavior as previous service).

Structures

• Label layers and feature layers separated.

• Labels/features regrouped by type, and reordered. Labels/features are created as single layers (one layer per feature class) by using definition queries.

• Layer order changed.

• Label font and halo changed.

• Some symbols updated.

• Post offices and State capitols are on by default while all other layers need to be manually turned on.

Geonames

• Label layers and feature layers separated.

• Labels/features regrouped by type, and reordered.

• Labels/features are their own layer and can be toggled on/off, rather than being grouped into a single layer (for example, schools, airports, and buildings are separate layers, rather than grouped into a Structure layer as they used to be). Labels/features are created as single layers (one layer per feature class) by using definition queries.

• Layer order changed.

• Label font and halo changed.

• Historical features are grouped by type (cultural-political, hydrographic, and physical).

• Symbols for most features updated.

• Communities (populated places) are on by default while all other layers need to be manually turned on.

Contours

• Label font and halo changed.

• Index contours have thicker lines than intermediate contours.

• Large-scale, 50-foot, and 100-foot contours are regrouped by type and sub-type, and all available sub-types are included in the layer list. Layer order numbers have changed as a result.

• Small-scale contours for the continental U.S., Alaska, Hawaii, Puerto Rico, and the U.S. Virgin Islands have been included, and are visible at 1:1,000,000-scale.

• Slight changes were made to visibility-through-scale settings.

Transportation

• Label font and halo changed.

• Small-scale transportation data originally from the National Atlas has been refreshed to replace previous content shown in the service.

• Additional road types are now included in the small-scale data layers: ferries and railroads.

• Large-scale local roads, ferries, tunnels, 4WD trails, and U.S. Forest Service roads are now able to be shown up to 1:300,000-scale.

• However, these layers are turned off by default, so users will have to manually turn them on to see them.
