Nombres de campo de ESRI?

8

Un archivo de forma que recuperé del sitio de Redistribución de Distritos de Pennsylvania contiene nombres de campo como TAPERSONS, TA1RACE. TAWHITEALN. TABLACKALN...oVAPERSONS, VA1RAC, VAWHITEALN...

Algunos forenses en línea sugieren que se trata de algún tipo de nombre de campo proporcionado por ESRI. Sin embargo, no puedo encontrar un modelo de datos o libro de códigos que describa las definiciones de campo. Prefiero no tratar de adivinar lo que significan, aunque los nombres sugieren datos demográficos.

¿Alguien puede señalarme un lugar donde pueda encontrar las definiciones?

Sus nombres de campo parecen estar vinculados a los datos del CENSO (muy similar a este archivo )

En base a esta respuesta, hice más búsquedas y se me ocurrió esto: muni.org/Departments/Assembly/Documents/… . Los campos de datos parecen ser datos demográficos del censo de 2010. Esta tabla cubrió todas las variables en mi archivo.

Esri proporciona pautas sobre convenciones de nomenclatura, pero no el contenido de los nombres en sí. Por ejemplo, los archivos de forma tienen un límite de 10 caracteres, los nombres de archivo de imagen ráster tienen un límite de 13 caracteres, ninguno debe tener espacios ...

Es probable que su respuesta no provenga de un sitio de Esri. Debe profundizar en el conjunto de datos y contactar a los propietarios originales para obtener sus metadatos, para obtener una respuesta exacta. Por lo general, documentos como este vienen con un archivo README.txt.

Esri tiene el Modelo de información del gobierno local (LGIM) que ofrece algunas recomendaciones para nombrar objetos comunes. Eso podría dar un poco de orientación, pero de nuevo: el propietario del conjunto de datos podría haber hecho sus propias reglas internas.
