Доступ файл ".csv" для карты наркопреступленний

George O 6 months ago • updated by Dmitriy Skougarevskiy 6 months ago 5

Здравствуйте всем--я студент, мы с коллегами на медицинском факультете в университете Джонс-Хопкинса работаем над проектом по эпидемиологической ситуации ВИЧ в РФ. Развитие ситуации связано с наркотиками, а мы используемся карты в программе ArcMap, чтобы описать аспекты самой ситуации. 


Мы с коллегами ищем файл ".csv" для карты наркопреступлений 2014 г., показана в этой ссылке: http://atlasjustice.com/drugmap/region.html# . 


Такой ".csv" используется в программе "ArcMap". Мы хотим знать, если этот файл существует, а если есть общий доступ к файлу. Спасибо большое за ваше внимание.

Hello Dmitriy, thank you for providing this data link. Is the data also convertible into SHP (shapefile for use in ArcMap)? 


Alternatively, I have converted the API to CSV and am now trying to convert the CSV into SHP using FME software, and I would like to know what the following attributes stand for (I realize some concern МВД data but am not entirely sure what they correspond to):


mvdvp10, mvdvp20, mvdvp30 (...) mvdvp90

fnsvp10 (...) fnsvp90

drshmvd

drshfns

prctoverla


My other question is that I am trying to convert non-spatial data (CSV) that you provided into spatial data, but for all attributes (mvdcode, oktmo, etc.), the data type is string. I am somewhat new to data mapping and I was hoping to find attributes that can be converted to x- and y- coordinate data types, to place each federal subject in a spatial data arrangement (map of RF). For each federal subject, I am unsure of which attributes represent coordinates or position--is this spatial information contained in the API? Please let me know. Thank you!

Dear George


First, I could suggest reading up a bit on shapefile data structure. Apart from the .shp (geometry file) it contains information on projection (.prj) and the data (.dbf), inter alia. The API now returns the data contained in the DBF, not the geometry. For geometry you can use any Russian region admin1 shapefile (say, from GADM) and then merge the data you got from the API (represented as the new DBF) on appropriately prepared region field with your geometry. Any GIS software in capable of that.


On attribute disambiguation: since the API is undocumented I suggest you reverse-engineer it — open one region on the map and look for the same values in corresponding API return for this region. That will give you an idea on what variables stand for.


On variable types: it's easily fixable in any statistical package (say, in R: v <- as.integer(v)).

Hello again Dmitriy, thank you for this help.


I tried reverse-engineering by opening regions on the map and looked for matching values in corresponding API but could not find matches for the attributes I listed above.


Since you kindly provided the API, is the .prj for the map also available? 


Thank you,


George

Dear George


mvdvp10 et al. are from percentile chart on the second tab of the infowindow.


On .prj — again, I can only suggest you familiarise yourself with shapefiles more. This file is related to your geometry, not the .dbf. So, I am afraid it is pointless to provide this file for you as it merely describes the chosen geometry.
