Web maps,
GIS,
And the take-away message
Web Maps, GIS, and the take-away message

1. The growth of the web. More interactive and engaging
websites. Mobile devices. This means maps in the hands
and eyes of billions.
2. Your map educates and it advocates, but…

Some examples

Looks great!
How do I do it?
TCPDF
1
1. Library for producing PDFs in PHP.
2. Can generate sophisticated PDFs: pictures,
borders, fills.
3. Can be tedious to adjust every pixel.

require_once('tcpdf/config/lang/eng.php');
require_once('tcpdf/tcpdf.php');

public function Header() {
$this->Image(K_PATH_IMAGES.'legend.jpg', 5, 100);

$arial = $this->addTTFfont('Arial.ttf', '', 'TrueType');
$this->SetFont($arial, '', 24, '', false);
$this->SetX(90);
$this->SetY(10);
$this->Cell(642, 55, "Duck Populations by Parcel, 2012", 0, 0, 'C');
}
public function Footer() {
$footfont = $this->addTTFfont('impact.ttf', '', 'TrueType');
$this->SetFont($footfont, '', 10, '', false);
}
}
$date = date("F j, Y");
$this->Cell(762, 10, "Map created on $date. Disclaimer and so forth.", 0, 0, 'C');
$pdf = new MYPDF(L, 'px', LETTER, true, 'UTF-8', false);
$pdf->AddPage();
$pdf->Image("/var/www/tmp/images.201209281107.jpg", 155, 70, 632, 507);
wkhtmltopdf / wkhtmltoimage
1
1. Command-line utilities for Linux, using a real
browser engine to draw pictures. Feed it a HTML
file, it generates a PDF or JPEG file.
2. Supports JavaScript, including Google Maps,
OpenLayers, et cetera.
3. Develop your PDF layouts in HTML, JavaScript,
and CSS!
4. Command-line tool means saving HTML to a file,
reading PDF as a file or capturing filename, …
