I've received a Arcgis layer containing streets, represented by polylines. When I identify a specific street, a large attribute table pops up:

Although I suspect that there are some custom attributes in this table, the majority of the attributes in the table are listed here: http://webapub.sjrwmd.com/arcgis/rest/services/srvc/srRegMapExcnty/MapServer/17

Is there a way to find a description of these attributes? Searching for 'arcgis street attributes/fields/...' does not yield any solutions. Since I'm new to arcgis, I've no idea where to start searching. Searching for some specific attribute names did not yield any results. This external page http://sumo.dlr.de/wiki/Networks/Import/ArcView gave some insights, but only a few attributes are defined there.

Similarly, is there somewhere more information on a polyline? I need to create a graph, exactly like this: Generating graph edge list from polyline and point shapefiles? Although I understand the proposed solution, it seems really error-prone to match points to end-points of edges based on their geographical coordinates. I don't understand why edges are not simply specified by (u,v), where u and v are identifiers of the starting and ending nodes. Two edges (i,j) and (u,v) are then connected if j=u. At least this is how it's done in Openstreet maps.

Unless there is metadata attached to the service that contains attribute information, the only way to get a description of the attributes is to contact whoever owns/maintains the service.

It doesn't appear to be an Esri/ArcGIS supplied service, rather it is hosted by a third-party (sjrwmd.com), so you may need to contact them directly for the information you require.

It turns out that the underlying maps use Navteq's Navstreets Street Data (or the newer HERE map data). The definitions of these fields/attributes can be found in NAVTEQ's Navstreets street data Reference Manual v4.4

Each street segment indeed has a start node and an end node, modeled by resp. REF_IN_ID and NREF_IN_ID. How to get the coordinates corresponding with these points is still an open question for me.

  • If there is metadata for geospatial data, it is probably out there on someone's web page. Metadata is often standalone XML, which is very searchable. I have found metadata for files by searching for the attribute field names, sometimes with the word "metadata." If you can import any useful metadata to your file, other people may find it there. And they should thank you. – danak Jul 19 '17 at 23:24
