I've received a Arcgis layer containing streets, represented by polylines. When I identify a specific street, a large attribute table pops up:
OBJECTID Shape LINK_ID ST_NAME FEAT_ID ST_LANGCD NUM_STNMES ST_NM_PREF ST_TYP_BEF ST_NM_BASE ST_NM_SUFF ST_TYP_AFT ST_TYP_ATT ADDR_TYPE L_REFADDR L_NREFADDR L_ADDRSCH L_ADDRFORM R_REFADDR R_NREFADDR R_ADDRSCH R_ADDRFORM REF_IN_ID NREF_IN_ID N_SHAPEPNT FUNC_CLASS SPEED_CAT FR_SPD_LIM TO_SPD_LIM TO_LANES FROM_LANES ENH_GEOM LANE_CAT DIVIDER DIR_TRAVEL L_AREA_ID R_AREA_ID L_POSTCODE R_POSTCODE L_NUMZONES R_NUMZONES NUM_AD_RNG AR_AUTO AR_BUS AR_TAXIS AR_CARPOOL AR_PEDEST AR_TRUCKS AR_TRAFF AR_DELIV AR_EMERVEH PAVED PRIVATE FRONTAGE BRIDGE TUNNEL RAMP TOLLWAY POIACCESS CONTRACC ROUNDABOUT INTERINTER UNDEFTRAFF FERRY_TYPE MULTIDIGIT MAXATTR SPECTRFIG INDESCRIB MANOEUVRE DIVIDERLEG INPROCDATA FULL_GEOM URBAN ROUTE_TYPE DIRONSIGN EXPLICATBL NAMEONRDSN POSTALNAME STALENAME VANITYNAME JUNCTIONNM EXITNAME SCENIC_RT SCENIC_NM TO_X_LANES FR_X_LANES FOURWHLDR COVERIND PLOT_ROAD REVERSIBLE EXPR_LANE CARPOOLRD PHYS_LANES VER_TRANS PUB_ACCESS LOW_MBLTY PARK_AVAIL PRIORITYRD SPD_LM_SRC TRANS_AREA L_FIPS R_FIPS L_STATE R_STATE L_CITY R_CITY MEANDER DRIVE_TIME L_ROUTE R_ROUTE FROM_ELEV TO_ELEV OLD_LROUTE OLD_RROUTE BREADTH WALK_TIME WALK_PEN NO_PARK_L NO_PARK_R TRAVCONS LEFT_NOTE RIGHT_NOTE FT_PENALTY TF_PENALTY FUTURNRES TUTURNRES AR_MOTOR EXPAND_INC DCA DISTANCE Serv_Time RSOwner RSClass RSDivision RSRoadClass RSPaveClass Route_Num Beltway Service Left Service Right # of Passes Left # of Passes Right Left Priority Right Priority Left Range Right Range RS_Truck RS_ServiceLeft RS_ServiceRight RS_TUTURNRES RS_FUTURNRES RS_MISC RS_5T_TRAVCONS RS_1T_TRAVCONS RS_HOOD_L RS_HOOD_R Shape_Length
Although I suspect that there are some custom attributes in this table, the majority of the attributes in the table are listed here:
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.
