ESRI-Feldnamen?

Ein Shapefile, das ich von der Pennsylvania Redistricting-Site abgerufen habe, enthält Feldnamen wie TAPERSONS, TA1RACE. TAWHITEALN. TABLACKALN...oderVAPERSONS, VA1RAC, VAWHITEALN...

Einige Online-Forensiker schlagen vor, dass dies eine Art von ESRI-bereitgestellten Feldnamen ist. Ich kann jedoch kein Datenmodell oder Codebuch finden, das die Felddefinitionen beschreibt. Ich möchte lieber nicht raten, was sie bedeuten, obwohl die Namen auf demografische Daten hinweisen.

Kann mich jemand auf einen Ort verweisen, an dem ich die Definitionen finden kann?

Ihre Feldnamen scheinen mit CENSUS-Daten verknüpft zu sein ( dieser Datei sehr ähnlich ).

Die Antwort von @Map_man führt Sie sicher zur Quelle Ihrer Daten.

Hier finden Sie einige Metadaten, die zu passen scheinen: https://www.arcgis.com/sharing/rest/content/items/ba931cd7a8f341ed9486a41c6f6798d4/info/metadata/metadata.xml?format=default&output=html

Esri bietet Richtlinien zu Namenskonventionen, jedoch nicht den Inhalt der Namen selbst. Zum Beispiel haben Shapefiles eine Obergrenze von 10 Zeichen, Rasterbild-Dateinamen eine Obergrenze von 13 Zeichen und Leerzeichen sollten keine Leerzeichen enthalten.

Ihre Antwort wird wahrscheinlich nicht von einer Esri-Site kommen. Sie sollten in den Datensatz eintauchen und sich an die ursprünglichen Eigentümer wenden, um deren Metadaten zu erhalten und eine genaue Antwort zu erhalten. Normalerweise werden solche Dokumente mit einer README.txt-Datei geliefert.

Esri verfügt über das Local Government Information Model (LGIM), das einige Empfehlungen für die Benennung allgemeiner Objekte enthält. Das könnte eine kleine Anleitung geben, aber auch hier könnte der Datensatzbesitzer seine eigenen internen Regeln erstellt haben.
