Nama Lapangan ESRI?

Shapefile yang saya ambil dari situs Pennsylvania Redistricting berisi nama-nama bidang seperti TAPERSONS, TA1RACE. TAWHITEALN. TABLACKALN...atauVAPERSONS, VA1RAC, VAWHITEALN...

Beberapa forensik online menyarankan bahwa ini adalah semacam nama bidang yang disediakan ESRI. Namun, saya tidak dapat menemukan model data atau codebook yang menjelaskan definisi bidang. Saya lebih suka tidak mencoba menebak apa artinya, meskipun namanya menyarankan data demografis.

Bisakah seseorang mengarahkan saya ke tempat di mana saya dapat menemukan definisi?

Nama bidang Anda tampaknya ditautkan dengan data SENSUS (sangat mirip dengan file ini )

Jawaban @Map_man akan mengarahkan Anda ke sumber data Anda, pasti.

Esri memberikan pedoman tentang konvensi penamaan, tetapi bukan isi dari nama itu sendiri. Sebagai contoh, shapefile memiliki topi 10 karakter, nama file gambar raster tutup pada 13 karakter, juga tidak boleh memiliki spasi ....

Jawaban Anda kemungkinan tidak akan datang dari situs Esri. Anda harus menggali dataset dan menghubungi pemilik asli untuk metadata mereka, untuk jawaban yang tepat. Biasanya dokumen seperti ini dilengkapi dengan file README.txt.

Esri memang memiliki Model Informasi Pemerintah Daerah (LGIM) yang memberikan beberapa rekomendasi untuk penamaan objek umum. Itu mungkin memberikan sedikit panduan, tetapi sekali lagi - pemilik dataset dapat membuat aturan internal mereka sendiri.
