wkb-parser's Introduction

Geo I/O WKB Parser

A parser which transforms Well-known binary (WKB) representations into geometric objects.

class MyFactory implements GeoIO\Factory
{
    public function createPoint($dimension, array $coordinates, $srid = null)
    {
        return MyPoint($coordinates['x'], $coordinates['y']);
    }

    // ...
}

$factory = MyFactory();
$parser = new GeoIO\WKB\Parser\Parser($factory);

$myPoint = $parser->parse('000000000140000000000000004010000000000000'); // POINT(2.0 4.0)

The error I get is:

in postgres, I get the following:

Removing

        if ($this->srid && $srid !== $this->srid) {
            throw new \RuntimeException(sprintf(
                'SRID mismatch between %s and expected %s.',
                json_encode($dimension),
                json_encode($this->dimension)
            ));
        }

from Parser.php eliminates the problem, but I'm guessing that is less than ideal.

Please let me know if you need more information.

Thanks!

MySQL parse point data error: Bad endian byte value 230

Project Info

geo-io/wkb-parser: v1.0.2
PHP 8.0.16
MySQL 8.0.28

Description

First I save some point data with the following query ST_PointFromText(POINT(90 180), 4326). Why MySQL expects the latitude first and then the longitude is beyond me, because latitude represents a Y coordinate and longitude an X coordinate. I therefore would expect a point to be defined as X Y. But that seems to be the case, because otherwise MySQL throws an error, so I just roll with it.
Then I retrieve that (raw) data back from the database and pass it on to GeoIO\WKB\Parser\Parser::parse. This throws the following exception:

GeoIO\WKB\Parser\Exception\ParserException : Parsing failed: Bad endian byte value 230.

Any idea what I'm doing wrong and how I can fix this?

Parsing MultiPolygons

I'm getting an error when I try to parse MultiPolygons from my database. Error message is:

ParserException in Parser.php line 43: Parsing failed: $polygons must contain at least two entries

Here's an example of WKB data that's throwing the error:

Error when parsing empty GeometryCollection

Hi, I'm trying to parse an empty geometery collection from a mysql db.

$parser->parse('00000000010700000000000000');

but it throws a ParserException: Parsing failed: Not enough bytes left to fulfill 1 double.

Release a proper version

Hey,

I'm using wkb-parser (and wkb-interface) in a project of mine.
So far it's been working great, but since you haven't released a proper version, I have to set minimum-stability to dev in my composer.json in all my projects where I want to use my own package.

Any chance you can release a proper stable release? Your test coverage is great, and I've not had any major issues so far.
