Geo::StreetAddress::US is a Perl extension for parsing US street addresses.

SYNOPSIS

use Geo::StreetAddress::US;

my $hashref = Geo::StreetAddress::US->parse_location(
"1005 Gravenstein Hwy N, Sebastopol CA 95472" );

my $hashref = Geo::StreetAddress::US->parse_location(
"Hollywood & Vine, Los Angeles, CA" );

my $hashref = Geo::StreetAddress::US->parse_address(
"1600 Pennsylvania Ave, Washington, DC" );

my $hashref = Geo::StreetAddress::US->parse_intersection(
"Mission Street at Valencia Street, San Francisco, CA" );

my $normal = Geo::StreetAddress::US->normalize_address( %spec );
# the parse_* methods call this automatically...

Geo::StreetAddress::US is a regex-based street address and street intersection parser for the United States. Its basic goal is to be as forgiving as possible when parsing user-provided address strings.

Geo::StreetAddress::US knows about directional prefixes and suffixes, fractional building numbers, building units, grid-based addresses (such as those used in parts of Utah), 5 and 9 digit ZIP codes, and all of the official USPS abbreviations for street types and state names.

Geo::Raster is a Perl extension for raster algebra.

SYNOPSIS

use Geo::Raster;
or
use Geo::Raster qw(:types);
or
use Geo::Raster qw(:types :logics :db);

Geo::Raster is an object-oriented interface to libral, a C library for rasters and raster algebra. Geo::Raster makes using libral easy and adds some very useful functionality to it. libral rasters are in-memory for fast and easy processing. libral rasters can be created from GDAL rasters. GDAL provides access to rasters in many formats.

Geo::Raster also adds the required functionality to display rasters in Gtk2::Ex::Geo.

Each cell in raster/grid is assumed to be a square.

The grid point represents the center of the cell and not the area of the cell (when such distinction needs to be made). TODO: This needs more attention.

A grid is indexed like this:

j = 0..N-1
------------------>
.
i = 0..M-1 .
.
.
V
there is also a (x,y) world coordinate system
maxY ^
.
.
y .
minY .
------------------>
minX maxX
x

minX is the left edge of first cell in line. maxX is the right edge of the last cell in a line. minY and maxY represent similarly the boundaries of the raster.

Geo::Coordinates::OSGB is a Perl module that can convert coordinates from Lat/Long to UK Grid.

A UK-specific implementation of co-ordinate conversion, following formulae from the Ordnance Survey of Great Britain (hence the name).

SYNOPSIS

use Geo::Coordinates::OSGB qw(ll2grid grid2ll);

# basic conversion routines
($easting,$northing) = ll2grid($lat,$lon);
($lat,$long) = grid2ll($easting,$northing);

# format full easting and northing into traditional formats
$trad_gr = format_grid_trad($easting,$northing); # TQ 234 098
$GPS_gr = format_grid_GPS($easting,$northing); # TQ 23451 09893
$landranger_gr = format_grid_landranger($easting, $northing) # 234098 on Sheet 176

# you can call these in list context to get the individual parts
# add "=~ s/s//g" to the result to remove the spaces

# and there are corresponding parse routines to convert from these formats to full e,n
($e,$n) = parse_trad_grid(TQ 234 098); # spaces optional, can give list as well
($e,$n) = parse_GPS_grid(TQ 23451 09893); # spaces optional, can give list as well
($e,$n) = parse_landranger_grid($sheet, $gre, $grn); # gre/grn must be 3 or 5 digits long
($e,$n) = parse_landranger_grid($sheet); # this gives you the SW corner of the sheet

# some convenience routines that bundle these up for you
map2ll();
map2grid();

# set parameters
set_ellipsoid(6377563.396,6356256.91); # not needed for UK use
set_projection(49, -2, 400000, -100000, 0.9996012717); # not needed for UK use

This module provides a collection of routines to convert between longitude & latitude and map grid references, using the formulae given in the British Ordnance Surveys excellent information leaflet, referenced below in "Theory".

The module is implemented purely in Perl, and should run on any Perl platform. In this description `OS means `the Ordnance Survey of Great Britain: the UK government agency that produces the standard maps of England, Wales, and Scotland. Any mention of `sheets or `maps refers to one or more of the 204 sheets in the 1:50,000 scale `Landranger series of OS maps.

Geo::Shapelib is a Perl extension for reading and writing shapefiles as defined by ESRI.

SYNOPSIS

use Geo::Shapelib qw/:all/;
or
use Geo::Shapelib qw/:all/;

my $shapefile = new Geo::Shapelib {
Name => stations,
Shapetype => POINT,
FieldNames => [Name,Code,Founded];
FieldTypes => [String:50,String:10,Integer:8];
};

while ( ) {
chomp;
my($station,$code,$founded,$x,$y) = split /|/;
push @{$shapefile->{Shapes}},{ Vertices => [[$x,$y,0,0]] };
push @{$shapefile->{ShapeRecords}}, [$station,$code,$founded];
}

$shapefile->save();

This is a library for reading, creating, and writing shapefiles as defined by ESRI(r) using Perl. The Perl code uses Frank Warmerdams Shapefile C Library (http://shapelib.maptools.org/). The library is included in this distribution.

Geo::ShapeFile is a Perl extension for handling ESRI GIS Shapefiles.

SYNOPSIS

use Geo::ShapeFile;

my $shapefile = new Geo::ShapeFile("roads");

for(1 .. $shapefile->shapes()) {
my $shape = $shapefile->get_shp_record($_);
# see Geo::ShapeFile::Shape docs for what to do with $shape

my %db = $shapefile->get_dbf_record($_);
}

ABSTRACT

The Geo::ShapeFile module reads ESRI ShapeFiles containing GIS mapping data, it has support for shp (shape), shx (shape index), and dbf (data base) formats.

The Geo::ShapeFile module reads ESRI ShapeFiles containing GIS mapping data, it has support for shp (shape), shx (shape index), and dbf (data base) formats.

METHODS

new($filename_base)

Creates a new shapefile object, the only argument it takes is the basename for your data (dont include the extension, the module will automatically find the extensions it supports). For example if you have data files called roads.shp, roads.shx, and roads.dbf, use new Geo::ShapeFile("roads"); to create a new object, and the module will load the data it needs from the files as it needs it.

type_is($numeric_type)

Returns true if the major type of this data file is the same as the type passed to type_is().

get_dbf_record($record_index)

Returns the data from the dbf file associated with the specified record index (shapefile indexes start at 1). If called in a list context, returns a hash, if called in a scalar context, returns a hashref.

x_min() x_max() y_min() y_max()

m_min() m_max() z_min() z_max()

Returns the minimum and maximum values for x, y, z, and m fields as indicated in the shp file header.

upper_left_corner() upper_right_corner()
lower_left_corner() lower_right_corner()

Returns a Geo::ShapeFile::Point object indicating the respective corners.

height() width()

Returns the height and width of the area contained in the shp file. Note that this likely does not return miles, kilometers, or any other useful measure, it simply returns x_max - x_min, or y_max - y_min. Whether this data is a useful measure or not depends on your data.

corners()

Returns a four element array consisting of the corners of the area contained in the shp file. The corners are listed clockwise starting with the upper left. (upper_left_corner, upper_right_corner, lower_right_corner, lower_left_corner)
area_contains_point($point,$x_min,$y_min,$x_max,$y_max)

Utility function that returns true if the Geo::ShapeFile::Point object in point falls within the bounds of the rectangle defined by the area indicated. See bounds_contains_point() if you want to check if a point falls within the bounds of the current shp file.

bounds_contains_point($point)

Returns true if the specified point falls within the bounds of the current shp file.

file_version()

Returns the ShapeFile version number of the current shp/shx file.

shape_type()

Returns the shape type contained in the current shp/shx file. The ESRI spec currently allows for a file to contain only a single type of shape (null shapes are the exception, they may appear in any data file). This returns the numeric value for the type, use type() to find the text name of this value.

shapes()

Returns the number of shapes contained in the current shp/shx file. This is the value that allows you to iterate through all the shapes using for(1 .. $obj->shapes()) {.

records()

Returns the number of records contained in the current data. This is similar to
shapes(), but can be used even if you dont have shp/shx files, so you can access data that is stored as dbf, but does not have shapes associated with it.

shape_type_text()

Returns the shape type of the current shp/shx file (see shape_type()), but as the human-readable string type, rather than an integer.

get_shx_record($record_index) =item get_shx_record_header($record_index)
Get the contents of an shx record or record header (for compatibility with the other get_* functions, both are provided, but in the case of shx data, they return the same information). The return value is a two element array consisting of the offset in the shp file where the indicated record begins, and the content length of that record.

get_shp_record_header($record_index)

Retrieve an shp record header for the specified index. Returns a two element array consisting of the record number and the content length of the record.

get_shp_record($record_index)

Retrieve an shp record for the specified index. Returns a Geo::ShapeFile::Shape object.

shapes_in_area($x_min,$y_min,$x_max,$y_max)

Returns an array of integers, consisting of the indices of the shapes that overlap with the area specified. Currently this is a very oversimplified function that actually finds shapes that have any point that falls within the specified bounding box. Currently it may miss some shapes that actually do overlap with the specified area, if there are two points outside the area that cause an edge to pass through the area, but neither of the end points of that edge actually fall within the area specified. Patches to make this function more useful would be welcome.

check_in_area($x1_min,$y1_min,$x1_max,$y1_max,$x2_min,$x2_max,$y2_min,$y2_max)

Returns true if the two specified areas overlap.

bounds()

Returns the bounds for the current shp file. (x_min, y_min, x_max, y_max)

shx_handle() shp_handle() dbf_handle()

Returns the file handles associated with the respective data files.

type($shape_type_number)

Returns the name of the type associated with the given type id number.

find_bounds(@shapes)

Takes an array of Geo::ShapeFile::Shape objects, and returns a hash, with keys of x_min,y_min,x_max,y_max, with the values for each of those ranges.

EpiGrass is a simulator of epidemics over networks. EpiGrass is a scientific tool created for simulations and scenario analysis in Network epidemiology.
For an in depth description of Epigrass capabilities, please refer to the documentation.
EpiGrass can interact with the GRASS GIS from which it can obtain maps and other geo-referenced information. However, EpiGrass does not require an installation of the GRASS GIS for most of its features.
Epigrass is free-software, licensed under the Gnu public license (GPL).
Currently, EpiGrass is supported only on the Gnu/Linux platform. If you would like to see it run on other platforms, you can volunteer to oversee the porting to a given platform. Since Epigrass is written entirely in Python, porting to other platforms should be very easy. However this is not the main priority of the EpiGrass development team.
Enhancements:
- An import bug was fixed.

Geo::Ellipsoids is a package for standard Geo:: ellipsoid a, b, f and 1/f values.

SYNOPSIS

use Geo::Ellipsoids;
my $obj = Geo::Ellipsoids->new();
$obj->set(WGS84); #default
print "a=", $obj->a, "n";
print "b=", $obj->b, "n";
print "f=", $obj->f, "n";
print "i=", $obj->i, "n";
print "e=", $obj->e, "n";
print "n=", $obj->n(45), "n";

CONSTRUCTOR

new

The new() constructor may be called with any parameter that is appropriate to the set method.

my $obj = Geo::Ellipsoid->new();

METHODS

set

Method sets the current ellipsoid. This method is called when the object is constructed (default is WGS84).

$obj->set(); #default WGS84
$obj->set(Clarke 1866); #All built in ellipsoids are stored in meters
$obj->set({a=>1, b=>1}); #Custom Sphere 1 unit radius
list

Method returns a list of known elipsoid names.

my @list=$obj->list;

my $list=$obj->list;
while (@$list) {
print "$_n";
}
a

Method returns the value of the semi-major axis.

my $a=$obj->a;
b

Method returns the value of the semi-minor axis.

my $b=$obj->b; #b=a(1-f)
f

Method returns the value of flatting

my $f=$obj->f; #f=(a-b)/a
i

Method returns the value of the inverse flatting

my $i=$obj->i; #i=1/f=a/(a-b)
invf

Method synonym for the i method

my $i=$obj->invf; #i=1/f
e

Method returns the value of the first eccentricity, e. This is the eccentricity of the earths elliptical cross-section.

my $e=$obj->e;
e2

Method returns the value of eccentricity squared (e.g. e^2). This is not the second eccentricity, e or e-prime see the "ep" method.

my $e=sqrt($obj->e2); #e^2 = f(2-f) = 2f-f^2 = 1-b^2/a^2
ep

Method returns the value of the second eccentricity, e or e-prime. The second eccentricity is related to the first eccentricity by the equation: 1=(1-e^2)(1+e^2).

my $ep=$obj->ep;
ep2

Method returns the square of value of second eccentricity, e (e-prime). This is more useful in almost all equations.

my $ep=sqrt($obj->ep2); #ep2=(ea/b)^2=e2/(1-e2)=a^2/b^2-1
n

Method returns the value of n given latitude (degrees). Typically represented by the Greek letter nu, this is the radius of curvature of the ellipsoid perpendicular to the meridian plane. It is also the distance from the point in question to the polar axis, measured perpendicular to the ellipsoids surface.

my $n=$obj->n($lat);

Note: Some define a variable n as (a-b)/(a+b) this is not that variable.

n_rad

Method returns the value of n given latitude (radians).

my $n=$obj->n_rad($lat);
rho

rho is the radius of curvature of the earth in the meridian plane.

my $rho=$obj->rho($lat);
rho_rad

rho is the radius of curvature of the earth in the meridian plane.

my $rho=$obj->rho_rad($lat);
polar_circumference

Method returns the value of the semi-minor axis times 2*PI.

equatorial_circumference

Method returns the value of the semi-major axis times 2*PI.

my $equatorial_circumference=$obj->equatorial_circumference;
shortname

Method returns the shortname, which is the hash key, of the current ellipsoid

my $shortname=$obj->shortname;
longname

Method returns the long name of the current ellipsoid

my $longname=$obj->longname;
data

Method returns a hash reference for the ellipsoid definition data structure.

my $datastructure=$obj->data;
name2ref

Method returns a hash reference (e.g. {a=>6378137,i=>298.257223563}) when passed a valid ellipsoid name (e.g. WGS84).

my $ref=$obj->name2ref(WGS84)

Geo::Coordinates::VandH is a Perl module that can convert and manipulate telco V and H coordinates.

SYNOPSIS To convert V: 5498 H: 2895 to lat/long coordinates:

use Geo::Coordinates::VandH;
$blah=new Geo::Coordinates::VandH;
($lat,$lon) = $blah->vh2ll(5498,2895);
printf "%lf,%lfn",$lat,$lon;

To find the mileage between 5498,2895 and 5527,2873 in miles:

use Geo::Coordinates::VandH;
$blah=new Geo::Coordinates::VandH;
printf "Distance between Pontiac, MI and Southfield, MI is approximately: %d milesn",$blah->distance(5498,2895,5527,2873);

Currently this package supports the translation of V+H to Lat/Long, and mileage calculations between two V+H coordinates.

Results are returned in decimal degrees for V+H to Lat/Long, and Miles for distance.

Future versions will convert Lat/Long to V+H coordinates.
