New York's Lat = 40.697132 and Log = -73.931351 which can be found in row 2 (highlighted below) and calculating distance with other cities from New York city using variables latitude and longitude. We are going to generate the distance between New York and other cities in KM. The data that we are going to use, is us_cities.dta that contains latitude and longitude of US cities. Syntax: geodist lat1 lon1 lat2 lon2, generate(new_dist_var)
#Geodist install stata install
Please install geodist if you haven't installed this command. The geodist command is used to calculate the distance between two locations, cities or latitude and longitude.ġ. Working with Geo-Distance Part 1: How do I calculate the distance between two locations with Stata? Read about them in the online help file (type help spmap).ī. Spmap has many options that control the color, legend, etc. Graphregion(icolor(stone)) - graph region color Plotregion(icolor(stone)) - plot region color Legend(region(lcolor(black))) - legend region line color
Title ("Poverty in Nepal by Districts") ///įcolor(Reds) - fill color of base map polygons (using Reds pallets here)Ĭlnumber(9) - number of classes or number of color legends
Spmap poverty using nepalcoord, id(id) /// Variable name type format label variable labelī) Napel Coordinate data (extracted from the map)Īdding Title, Legends and Colors to the base map based on the povery level dta datasets: nepaldb.dta and nepalcoord.dta.Ī) Nepal Dataset (extracted from the map) In any case, the translation has created two new. We would have translated MapInfo files the same way, but we would have used the command mif2dta instead of shp2dta. The Nepal map, however, took only a few seconds. Shp2dta can take several minutes to run, depending on the map’s size and level of detail. genid(id) specified that we wanted the ID variable created in nepaldb.dta to be named id.coordinates(nepalcoord) specified that we wanted the coordinate file to be named nepalcoord.dta.database(nepaldb) specified that we wanted the database file to be named nepaldb.dta.Pay attention to the three options we specified: Shp2dta using shape_files_of_districts_in_nepal, database(nepaldb) coordinates(nepalcoord) genid(id) We use shp2dta command to extract data from shapefile in the curernt directory.

#Geodist install stata download
Please download the example dataset here:Ī) Nepal Shapefiles (shape_files_of_districts_in_nepal.rar) - Please unzip it - we need only. We are going to use Nepal Country Map shapefile to find poverty level in each state by merging Poverty dataset. Those maps are available from public or provate sources. Find a map (as ESRI shapefile or a Mapinfo format file).Ī map recordes the geometry and attribute information of spatial features.
Important Note: This works only on STATA version 15.1 and above versions. Shp2dta using shpfilename, database(filename) coordinates(filename) Install the spmap, shp2dta, and mif2dta commands You can use ESRI shapefiles or MapInfo Interchange Format.ġ. Obtain and install the spmap, shp2dta, and mif2dta commands and search the web for the files that describe the map onto which you want to graph your data. With spmap, you can graph data onto maps and produce results. Working with spmap and maps How do I graph data onto a map with Stata?
