Feature Representation
In addition to the generic FME feature attributes that FME Workbench adds to all features (see About Feature Attributes), this format adds the format-specific attributes listed below upon reading.
Attribute Name |
Contents |
---|---|
arcgisonline_type |
The type of geometric entity stored within the feature: arcgisonline_point arcgisonline_multipoint arcgisonline_polyline arcgisonline_polygon arcgisonline_no_geom |
Points
arcgisonline_type: arcgisonline_point
Features tagged with this value consist of a single point.
Multipoints
arcgisonline_type: arcgisonline_multipoint
Features tagged with this value consist an aggregate of one or more points.
Line
arcgisonline_type: arcgisonline_polyline
Features tagged with this value consist of a single line, a set of lines that form a continuous path, or a set of lines that are disjoint.
Polygon
arcgisonline_type: arcgisonline_polygon
Features tagged with this value can be a single polygon, a donut polygon, or a multi-area comprised of single polygons, donuts, or both.
No geometry
arcgisonline_type: arcgisonline_no_geom
Features tagged with this value have no geometry. Features from tables have no geometry, whereas features from layers do.
Attribute Types
This section of the <ReaderKeyword>_DEF statement defines the field types for a layer:
Column Type |
Description |
---|---|
esriFieldTypeSingle |
Single fields store 32-bit floating point values. There is no ability to specify the precision and width of the field. |
esriFieldTypeDouble |
Double fields store 64-bit floating point values. There is no ability to specify the precision and width of the field. |
esriFieldTypeInteger | Integer fields store signed integers. |
esriFieldTypeSmallInteger | Small integer fields store 16-bit signed integers. |
esriFieldTypeString(width) | String fields store arbitrary string data, up to a specified size limit. |
esriFieldTypeDate(width) |
A date field stores date and/or time. It is represented as a UNIX timestamp within ArcGIS Online. FME converts this format to the FME date/time format. |
esriFieldTypeGUID(width) | A globally unique identifier (GUID) field. The width is ignored. It is exposed to maintain parity with the ArcGIS REST API. |
esriFieldTypeGlobalID(width) | The Global ID field. Each feature type may define at most one field with this type. Its value is a GUID. The width is ignored. It is exposed to maintain parity with the ArcGIS REST API. |
