[GIS] Countries’ Latitude and Longitude range

gpslatitude longitude

Do countries have a Latitude and Longitude range?.

Is it possible to get the latitude and longitude range or boundary for each country.

UK lat and long is 51.5000° N, 0.1167° W.

What is the Maximum and minimum ,latitude and longitude i can have to be still in the UK?

For an example, i have 2 sets(a,b) of lat and long, I start at set a which i know is within the country but i don't know if Set b my destination is still within the country.

Yes. It is possible to get lat/long range for each country. The minimum and maximum lat/long is available at the below link. Hope this helps. https://web.archive.org/web/20150319012353/http://opengeocode.org/cude/download.php?file=/home/fashions/public_html/opengeocode.org/download/cow.txt

[GIS] How to obtain the maximum/minimum longitude and latitude for a polygon

Unless I'm misunderstanding the question, the shape's .extent property is all you need.

with open('out.txt', 'wb') as out_text_file, arcpy.da.SearchCursor('path_to_data', ('msa', 'SHAPE@')) as cur:
    print >>out_text_file, "msa     min_lon   max_lon   min_lat  max_lat"
    for row in cur:
        msa, ext = row[0], row[1].extent
        print >>out_text_file, "{0:5}   {1:2.4}   {2:2.4}   {3:2.4}   {4:2.4}".format(msa, ext.XMin, ext.XMax, ext.YMin, ext.YMax)

if interested in a python suggestion - using OGR

from osgeo import ogr, osr

# setup function to reproject coordinates
def convertCoords(xy, src='', targ=''):

    srcproj = osr.SpatialReference()
    srcproj.ImportFromEPSG(src)
    targproj = osr.SpatialReference()
    if isinstance(targ, str):
        targproj.ImportFromProj4(targ)
    else:
        targproj.ImportFromEPSG(targ)
    transform = osr.CoordinateTransformation(srcproj, targproj)

    pt = ogr.Geometry(ogr.wkbPoint)
    pt.AddPoint(xy[0], xy[1])
    pt.Transform(transform)

    return([pt.GetX(), pt.GetY()])

you can then feed the lat/long coordinates to the function, with appropriate epsg codes (for this example, we'll use WGS84 as the input and albers for the output):

coords =  (-116.419389, 38.802610)
albersXY = convertCoords(coords, 4326, 5070)

add 20 miles to one direction of the albers coordinates (which are in meters)

albersXY[0] = albersXY[0] + 20 * 1609.344
# albersXY[1] = albersXY[1] + 20 * 1609.344

then convert from albers back to WGS

newlonlat = convertCoords(albersXY, 5070, 4326)
print(newlonlat)
>>> [-116.13229978439009, 39.14407586190597]
